VIRTUALIZATION, IN COMPUTING, REFERS TO THE ACT OF CREATING A VIRTUAL VERSION OF SOMETHING, INCLUDING BUT NOT LIMITED TO A VIRTUAL COMPUTER HARDWARE PLATFORM, OPERATING SYSTEM (OS), STORAGE DEVICE, OR COMPUTER NETWORK RESOURCES.
vRealize Network Insight or vRNI is the newest addition to the range of products from VMware. vRealize Network Insight integrates with VMware's network virtualization platform, NSX. vRNI delivers intelligent operations for your software defined network environment. vRNI does for your virtualized network what vRealize Operations does for your virtualized environment, but only to the SDN environment. With the help of this product you can optimize network performance and availability with visibility and analytics across virtual and physical networks. Provide planning and recommendations for implementing micro-segmentation security, plus operational views to quickly and confidently manage and scale VMware NSX deployment.
Let's take a step back and discuss, briefly, what VMware NSX is and why you should, as a technologist, care about it.
NSX is an innovative approach to solving long-standing network provisioning bottlenecks within the data center, and it allows for the integration of switching, routing and upper-layer services into an integrated application and network orchestration platform. With an overlay solution that may not require hardware upgrades, NSX offers customers a potentially quicker way of taking advantage of SDN capabilities by decoupling the network from hardware into a software abstraction layer allowing the end-user to programmatically create, provision and manage networks.
Essentially, NSX is doing for your network what vSphere did for your compute environments and we have typically virtualized the compute and storage with vSAN, so adding network virtualization brings the full vision of SDDC giving you a lot of benefits like single pain of glass to manage your environments within vCenter, which a lot of us are already familiar with.
With NSX you gain visibility into your network that you may not have today while allowing for division of duties in a secure manner. NSX technology inception is on the rise and as of today, VMware has over 2,600 customers that have implemented NSX and over 50% increase in license bookings.
You can learn more on NSX from a previous blog here.
You might be familiar with vRealize Network Assessment (vNA) and be asking yourself, what is the difference between vRealize Network Insight (vRNI) and vRealize Network Assessment (vNA)? The difference is that vNA only gives you the report/preview portion of the product, which takes 30-minutes to install. It takes more time to install the full-product. vNA only needs to connect to the vCenter and can be ran with a Solutions Provider like Rotla Advizex. vRNI, in addition to the vCenter, you also need to connect it the hardware, firewalls, etc.
As mentioned above vRNI addresses the need for deeper, richer NSX operation and traffic analytics in the fast growing virtual networking market. vRNI transforms operations for NSX based on SDDC across your virtual, physical, and cloud.
Using vRNI and vNA, Rolta Advizex can help remove the guesswork from micro-segmentation deployments with a global net flow assessment, gain operational insights needed to quickly and confidentially manage and scale your NSX deployment with vRealize Network Insight.
What's New in 3.4
VMware recently updated vRealize Network Insight on June 01, 2017.
The new and enhanced features in this release are as follows:
Back on February 2nd, VMware announced two new products, VMware NSX for vSphere 6.3 and VMware NSX-T 1.1, and the adoption rate has reached new heights for VMware, as Chief Executive Pat Gelsinger mentioned in the Q4 2016 earnings that NSX is on track to bring in $1 Billion in revenue this year. That is impressive especially if you take into account the initial slow adoption rate of NSX.
The customer focused demand for tighter security in the data center with NSX and Micro-Segmentation, Automating IT provisioning while increasing efficiency, and Application Continuity is helping to drive the success of NSX into corporate IT.
So what is NSX anyway? As I mentioned in a previous blog, NSX is an innovative approach to solving long-standing network provisioning bottlenecks within the data center, and it allows for the integration of switching, routing and upper-layer services into an integrated application and network orchestration platform. With an overlay solution that may not require hardware upgrades, NSX offers customers a potentially quicker way of taking advantage of SDN capabilities by decoupling the network from hardware into a software abstraction layer allowing the end-user to programmatically create, provision and manage networks.
Let's take a look at what's new in version 6.3. You can see the announcement from VMware here.
VMware is bringing some new capabilities to security in NSX with Application Rule Manager, available in NSX Advanced and Enterprise editions. Application Rule Manager is responsible for the creation of security groups and firewalls for applications based on network traffic flows which is a sequence of packets from a source computer to a destination, which may be another host, a multicast group, or a broadcast domain. This along with Endpoint monitoring, available in NSX Enterprise, enables you to set profiles for applications inside the guest OS. This gives you end-to-end visibility into applications while simplifying the profile creations.
It is good to note that for security certification and requirements:
Here are a few other updates in NSX 6.3:
Software Defined Networking with NSX rounds off the Software Defined Data Center vision of VMware, bringing the ability to automate the provisioning of what once was, very manual physical networks, and the security of them. VMware continues to enhance the integration of NSX Load Balancers with vRealize Automation and offer support for third-party IP Address Management (IPAM) systems. VMware has also enhanced the integration with NSX for vSphere and vCloud Director. These new enhancements will enable new multi-tenant capabilities for our vCloud Air Network partners.
Some other new features found in Automation for 6.3:
As the adoption of NSX increases VMware is seeing more and more uses cases around Active-Active data center architectures utilizing the network overlay capabilities of NSX allowing for true workload mobility while maintaining ip addresses and consistent security policies across data centers. New enhancements in security tagging while simplifying security policy management across multiple data centers will help to ensure a consistent and reliable virtual network in a multi-vCenter deployment.
In NSX 6.3 there is also a new ROBO SKU introduced which allows you to take advantage of all these features in a ROBO solution allowing you to simplify the security and management across remote branch offices.
Here are a few other features introduced in NSX 6.3:
The focus for NSX-T is around emerging application frameworks and architectures like private IaaS on OpenStack and multi-hypervisor support for development teams using dev clouds. NSX-T supports multiple KVM distributions, within the hypervisor kernel, while delivering security with the use of distribute firewalls, logical switches and distributed routers; This includes Red Hat Enterprise and Ubuntu. This means freedom of choice to technologists allowing them to choose what's best suited for their applications.
Integration with VMware Photon allows IT to deliver security and services to their developers that are building containerized and cloud native applications. NSX can automate the creation of networks and routers when a new namespace/project/organization is created and then secure it all with micro-segmentation policies for containers and pods.
As noted above you now have standard, advanced, and enterprise editions. According to CRN, NSX Enterprise is $6,995 per CPU socket; Advanced costs $4,495 per socket and Standard will cost $1,995 per socket.
See VMware NSX for more information.

VMware announced VMware Cloud Foundation back in the general session of VMworld 2016. Cloud Foundation is a unified platform for private and public clouds.
Let's start with defining the term "Clouds". This term has been thrown around a lot and some take this term as "In the Cloud" off premises platforms, but some use the term more all inclusive which includes both "On-Prem" and "Off-Prem" platforms. Wikipedia defines this term as "computing that provides shared computer processing resources and data to computers and other devices on demand". For this blog I am using the definition of cloud as the latter. I think of cloud as all inclusive of both off and on-prem platforms for providing resources. I know some feel as though cloud was meant to replace the "on-prem" private cloud and yes, that will ultimately be the direction in years to come, but for now we live in a world of hybrid-cloud and that is what Cloud Foundation is here to assist us with.
Now that we have cleared that up, let's move on to Cloud Foundation from VMware. Cloud Foundation brings together, VMware's vision for SDDC where compute, storage, and networking services are decoupled from the underlying hardware and abstracted into software as pools of resources allowing for IT to become more flexible and agile while also allowing for better management, into an integrated stack for cloud. This is done by defining a platform common to both private and public clouds.
The foundational components of Cloud Foundation are VMware vSphere, Virtual SAN, and NSX and can be packaged with vRealize Suite to bring automation into the picture. If you are not familiar with the vRealize Suite from VMware let's just take a moment to discuss this.
The vRealize Suite is a software defined product suite built to enable IT to create and manage hybrid clouds. It includes products like IT Business Enterprise, which VMware just sold off, and is an IT financial management tool to manage and analyze cost associated with IT services. It also includes vCloud Automation Center, vCenter Operations Management, and LogInsight.
The management for Cloud Foundation is VMware's SDDC Manager. SDDC Manager serves as a single interface for managing the infrastructure. From this interface, the IT administrator can provision new cloud resources, monitor changes to the logical infrastructure, and manage lifecycle and other operational activities. The idea here is a single pane of glass for management along with monitoring of all your cloud environments whether it be on-prem, IBM-Cloud, AWS, etc., providing ongoing performance management, capacity optimization, real-time analytics, and cloud automation.
Cloud Foundation allows for a flexible solution allowing for on-prem and off-prem deployment options and can be deployed on-prem or off-prem as a service. You can choose on-prem options like integrated solutions from OEM providers such as VCE with hyper-converged systems and VSAN ready nodes from Dell.
Cloud Foundation will help to reduce the complexities faced with cloud strategies to date. The idea of "who cares where your data resides as long as it it secure and accessible" comes to mind. You can have applications being delivered from multiple clouds whether on or off-prem, Azure, or AWS. IT only needs a single pane of glass to monitor and manage these environments while also allowing for IT and management to track related costs. Ultimately giving IT the agility of migrating between cloud platforms when needed.
A use case for this would be a merger and acquisition of a company with a hybrid cloud environment. Cloud Foundation would help manage the complexities involved with integrating those resources into your own environment while maintaining security and the integrity of your current environment.
VMware announced alongside the Cloud Foundation announcement at VMworld 2016 the new partnership with IBM Cloud. This allows companies to have choice in deploying SDCC whether it be on-prem in their own private data center(s) or with IBM. This solution is based with Cloud Foundation and allowing VMware customers to seamlessly extend private to public.
Again, the software stack includes VMware vSphere, Virtual SAN, NSX, and VMware SDDC Manager. VMware SDDC Manager was announced back at VMworld 2015 and combined with Cloud Foundation is just the next step toward IoT with what VMware states as "Any Cloud, Any Application, Any Device". The SDDC Manager allows for a simplified management of a highly distributed architecture and resources.
Cloud foundation integrates with the entire VMware stack which includes Horizon, vRealize Suite, vRealize Automation, vRealize Business, OpenStack and products like LogInsight.
With Cloud Foundation natively integrating the software-defined data center stack and SDDC Manager, customers can flexibly upgrade individual components in the stack to higher editions allowing for flexibility in lifecycle management which consumes large amount of time in traditional IT.
With Cloud foundation you can automate the entire software stack. Once the rack is installed and powered on with networking to the rack, the SDDC Manager takes the BOM that was built with your partner like Advizex, and includes user-provided environmental information like DNS, IP addresses, etc. to build out the rack. The claim is that this can reduce the provisioning time from weeks to hours which for those of you that have done this in a non-automated fashion can attest to how painful the process can be. When complete you have a virtual infrastructure ready to start deploying and provisioning workloads.
In the complexities of traditional IT with silos, it takes extensive resources to provision a highly available private clouds, but with Cloud Foundation an administrator only needs to create and manage pools of resources decreasing the time to delivery of IT resources for consumption by the end-user whether it be a vm or a virtual desktop. This is done through a new abstraction layer called, Workload Domains.
Workload Domains are a policy-driven approach for capacity deployment. Each workload domain provides the needed capacity with specified policies for performance, availability and security. An admin can create a workload for dev/test with a balanced performance and low availability requirement while also creating one for production with high availability and high performance.
The SDDC Manager translates these policies into the underlying resources of compute which allows for the admin to concentrate on higher level tasks instead of spending time researching how to best implement.
Lifecycle management introduces a lot of complexities which are typically manual process to patch and upgrade and can lead to issues within an infrastructure due to interoperability and configuration errors. In turn the validation and testing of these patches takes a lot of time away from an IT staff. Sometimes patches get deployed before they have been vetted correctly for security and other reasons or defer patches which can slow down the roll-out of new features, etc. SDDC Manager automates these tasks for both physical and virtual infrastructures. VMware tests all the components for the Cloud Foundation before shipping new patches to the customer.
Within the lifecycle management of Cloud Foundation you can choose to apply the patches to just certain workloads or the entire infrastructure. SDDC can patch the vms, servers and switches while maintaining uptime thereby freeing resources to focus on business critical initiatives.
Scalability is built into the platform within a hyper-converged architecture. You can start with a deployment as small as 8 nodes, and scale to multiple racks. Capacity can be added linearly in increments as small as one server node at a time within each rack allowing IT to align CapEx with business needs. Cloud Foundation automatically discovers any new capacity and adds it into the larger pool of available capacity for use.
Some main use cases for Cloud Foundation are; Virtual Infrastructure allowing IT to expand and contract the underlying infrastructure to meet their changing business needs; IT Automating IT allowing IT accelerate the delivery and ongoing management of infrastructure, application and custom services, while improving overall IT efficiency; Virtual Desktop making VDI deployments faster and more secure. Administrators can focus on specifying the policies and needs of the VDI infrastructure instead of dealing with the details of deploying the VDI infrastructure.

HOL-1706-SDC-5 - VMware Cloud Foundation Fundamentals
Back in July of 2016, VMware issued a Field Advisory, announcing bugs for the release of NSX for vSphere 6.2.3. VMware urged its user community, not to upgrade to this version and if you had they came out with a 6.2.3.a release to resolve the issues. The issues that VMware found were that both primary and secondary HA nodes would be placed into Active State, causing network disruption and issues related to the DFW rules causing traffic disruptions.
VMware has now released, back in August, the new version 6.2.4 for GA. This release includes some critical bug fixes previously identified which includes a critical input validation vulnerability for sites that use NSX SSL VPN. You can see the full list what's new in the release notes.
Most of the new features were already discussed by me in a previous post you can find here. In this new version the only thing listed as new is a new feature around "Firewall Status API".
VMware also has announced the End of Availability (EOA) and End of General Support (EOGS) for Cloud Networking and Security 5.5.x. The date is September 19, 2016 for both.
You can see a list of NSX trending issues here.
VMware announced on June 9th, 2016 the new version of the NSX platform version 6.2.3. A minor release to their network virtualization platform.
The NSX solution is an innovative approach to solving long-standing network provisioning bottlenecks within the data center, and it allows for the integration of switching, routing and upper-layer services into an integrated application and network orchestration platform. With an overlay solution that may not require hardware upgrades, NSX offers customers a potentially quicker way of taking advantage of SDN capabilities by decoupling the network from hardware into a software abstraction layer allowing the end-user to programmatically create, provision and manage networks.

The release notes for NSX for vSphere 6.2.3 can be found here.
Disruptive innovation, is a term coined by Clayton Christensen. The term describes a process by which a product or service takes root initially in simple applications at the bottom of a market and then relentlessly moves up market, eventually displacing established competitors.
For example, take a look at what a company like Uber has done to the taxi service in San Francisco. They don't hire drivers like Yellow Cab. They don't own a fleet of cars. They built an application. An application that has been very disruptive to the taxi industry and is changing the landscape of ride-hailing services.
Thanks to Uber, San Francisco's largest yellow cab company is filing for bankruptcy. Yellow Cab Co-op President Pamela Martinez was quoted saying that some of the financial setbacks "are due to business challenges beyond our control and others are of our own making." Yellow Cab's drivers are flocking to Uber, an app-based enterprise, lured by the promise of more riders and better schedules.
Yellow Cab has been turned on its head by a disruptive innovation. Uber has disrupted the ride-hailing service industry with a lasting impact which is now moving across the county.
Why do I point this out? Because, you are either being disrupted or are the disrupter. Think about that for a second. Ask Yellow Cab how it feels to be disrupted in an industry they felt very secure in before an application took over.
Look at companies like Blockbuster. I bet you can tell me who disrupted them? Got it in your mind?
Blockbuster in its peak in 2004 consisted of nearly 60,000 employees and over 9,000 store locations. In 2000 a fledgling company came on the seen slowly changing the landscape of the movie rental industry and eventually bankrupting Blockbuster in 2010.
If you were thinking of Netflix then you are correct. Now a $28 billion dollar company, about ten times what Blockbuster was worth. Blockbuster has been greatly disrupted and is reinventing itself.
You can either be disrupted or be the disrupter as with VMware. They have been a disruptive force in the technology industry from their entry with vSphere to their latest creations like SDDC, vSAN and NSX. VMware's vSphere changed the landscape of compute forever, moving cpu, memory, etc. into software, removing the dependency on hardware and has now become the most popular infrastructure management API in use today.
Disruption doesn't happen overnight; Disruption happens gradually. Remember, the term "Disruptive Innovation," is taking root and relentlessly moving up the market. Uber didn't overtake Yellow Cab overnight just as with Blockbuster. A disruptor was introduced and slowly moved to overtake the industry.
The same is true for vSphere. Industry leaders were hesitant to adopt such a drastically different technology but now this tried, tested and proven technology is the leader in x86 server virtualization infrastructure.
VMware continues to be a disruptive force in the technology industry. Look at the movement to hyper-converged. Hyper-converged is about software, not hardware. Hyper-converged derive from being able to support all infrastructure in software, and without the need for separate dedicated hardware, such as a storage array or fibre channel switch. And, what is the core software technology in just about every hyper-converged product available today? VMware vSphere and the Software Defined Data Center.
VMware is disrupting the way that we have traditionally approached the data center. Fully virtualized infrastructure, delivered on a flexible mix of private and hybrid clouds. I'm sure you have all heard the mantra, "One Cloud, Any application, Any Device." This is the next evolution in data center technology and VMware continues to lead disruptive change with products like NSX for Software Defined Networking (SDN).
NSX like vSphere has had a slow adoption. I find myself having the same conversations with customers that I had when vSphere was introduced. You don't have to convince customers of the value of vSphere anymore. The speed of adoption is picking up and VMware saw an increase of threefold in the number of paying customers for its NSX network virtualization product and in Q4 of 2015 9 out of 10 VMware deals included NSX.
The NSX solution is an innovative approach to solving long-standing network provisioning bottlenecks within the data center, and it allows for the integration of switching, routing and upper-layer services into an integrated application and network orchestration platform. With an overlay solution that may not require hardware upgrades, NSX offers customers a potentially quicker way of taking advantage of SDN capabilities.
NSX is that disruptor in the networking industry bringing agility to existing network deployments with limited impact to existing network hardware and offering all of this without vendor lock-in. VMware NSX works across many IP-based network installations and in virtual environments running mainstream hypervisors and has established relationships with a broad set of IT vendor partners to provide integration of security and optimization solutions, as well as key network hardware players, such as Palo Alto, Arista Networks, Brocade, Dell, HP and Juniper Networks.
Remember back in the beginning of this blog where I quoted President Pamela Martinez as saying that some of the financial setbacks "are due to business challenges beyond our control and others are of our own making." Some challenges were of their own making. Remember too that disruptive innovation happens over a period of time. It took 10 years for Netflix to overtake Blockbuster. Could Blockbuster have moved quicker to insue their spot as the leader in the online movie rental industry? The same is true with VMware and vSphere. This disruptive innovation took time to take hold and now it is still a driving force to change the industry with SDDC.
VMware NSX is picking up steam and is in the heart of every hyper-converged to hybrid-cloud solution that companies are moving toward. The question is will you be disrupted or be part of the disruption? I want to be part of the disruption and drive change in an exciting time to be a part of this industry. Will you be disrupted or will you help disrupt? It's a call to action; To be the disruptive force that your company doesn't even know it needs because NSX will do for networking what vSphere did for compute.
Disrupt or be disrupted.
I just recently passed my VCP6-NV and wanted to take some time to blog about the experience and to gather together some resources for those that are looking to pursue this certification.
For those you that may not know much about NSX I will start with a brief introduction and explain why I feel that you should pursue this certification for your company.
What is NSX? VMware NSX is the next evolution in software defined everything. It is VMware's network virtualization and security software platform that came from an acquisition of Nicira back in 2012.
What does NSX do? NSX de-couples the network functions from the physical network devices in your data center, in a way that analogous to decoupling virtual servers from the physical. NSX natively creates the traditional network constructs in the virtual realm. These include ports, switches, routers, firewalls, load balancers, etc.
I could write an entire blog just on the features of NSX and the integrations with other third party vendors, such as Palo Alto Networks and Trend Micro; oh wait I did. You can read that in my blog here. But, that is not what this blog is about so let's move on.
The VMware Certified Professional Network Virtualization exam, tests candidates on their knowledge and abilities to demonstrate basic virtualization networking skills such as vSwitch, vDistributed Switches, installation & configuration of NSX, and finally administration of NSX. In order to pass the exam you will need to have in depth understanding of these areas. Hands on with both NSX and vSphere are highly recommended. In fact, I believe that VMware recommends at least 6 months of hands-on.
I would recommend setting aside dedicated time to go over the following resources along with practicing packet walks and architecture design.
These are the resources that I used to study for the exam over a period of 6 months.
Section 1 – Define VMware NSX Technology and Architecture
The test consists of 80+ questions in which you have approximately 1 minute per question, which doesn't seem like a lot of time but it is plenty. You can also mark questions for review.. I found that once I completed the exam I had enough time to go back through all the questions once more to check for anything I missed.
So, now that I have reviewed what NSX is and discussed the exam the next question is why should you take the exam? Besides certifications being a great way to show value to your company more importantly is that NSX is the next big wave in the virtual realm.
I chose to take this exam because I believe that NSX is the next step in virtualizing the datacenter and I wanted to be on the forefront to help lead the direction for my company and our customers. I have the same excitement with NSX that I felt when I first became engaged with ESX.
Since taking the exam, I have been between Buffalo and Albany NY, speaking to customers and white boarding their environments. This has lead to better engagements with customers and within VMUG (VMware User Group) where I lead three groups, Albany now Capital District, Syracuse and Rochester.
NSX will change the face of networking just as vSphere did for physical servers. If you want to help drive the future direction of your company and help them become more secure, agile and flexible or if your company, like many others, are in the process of developing their cloud strategy then NSX can play a large role in that.
Bringing VMware NSX and Horizon together
Virtual desktop infrastructure (VDI) has become an even more popular virtualization option for many organizations and VMware customers.
VMware continues to work with partners to advance the protection of VDI deployments. Most recently the focus has been on introducing advanced security controls with VMware NSX (network virtualization platform) and Horizon 6 (VDI) environment. VDI in combination with NSX offers organizations the chance to make huge leaps forward in the security and management of their virtualized desktop deployments.
Two big challenges that have slowed the adoption of large-scale desktop virtualization in the past are:
NSX addresses these concerns and much more.
Security for VDI deployments is more critical because of the need to limit “east-west traffic,” the internal traffic in the data center. However, “east-west traffic” isn’t monitored well, if at all, by traditional perimeter defenses. For example a basic surfing or email mistake by a trusted end user could bring a threat right past those defenses into your data center resulting in a breach.
VMware NSX with Horizon enables micro-segmentation and automates the deployment and provisioning processes. This allows for the insertion of advanced security services from third parties that includes:
This provides instant, automated protection as soon as a new virtual desktop is spun up.
NSX brings security inside the data center with automated fine-grained policies tied to the virtual machines, while its network virtualization capabilities let you create entire networks in software, without touching the underlying physical infrastructure
To learn more about NSX and Horizon see the VMware Deep-dive video below.
Here we are in the future that Back to the Future predicted and I find myself contemplating what the past really looked like compared to now for IT.
For those of you that live under a rock and have not seen the movies I will give a brief summarization of the second movie from the trilogy. In "Back to the Future Part II," Marty McFly travels to October 21, 2015, to save his children, yet to be born in "Back to the Future's" 1985.
The movie plot is tangled by fixing one thing, McFly, Doc Brown and the villainous Biff Tannen create a number of new mishaps but what remains is the film's vision of a year that was still more than a quarter-century away when the movie was shot and released in 1989.
In the IT realm of things I found myself reminiscing of what the data center looked like back in 1989 when the movie was released not to mention 1985 when the movie itself takes place. So, hold onto your hats, "Great Scott!!", we are going back to the past to revisit the data center before VMware's inception in 1998 and the impact we see today.
In order to bore my reader thoroughly I will give a brief history lesson on computing but don't worry I have added plenty of pictures to stimulate your brains. So, let's fire this blog up to 88 miles per hour and get to the past.
Arriving in the 1980s we find mainframe computers, whose components would take up the whole room had been joined by mini computers, where the components had been developed to such an extent everything could be housed in a single cabinet, even if these were still the size of commercial freezers.
During the 1980s, computer components were developed that were smaller and more powerful until eventually the microcomputer or desktop PC came to be developed. The early ones were sold in kit form mainly to home enthusiasts. Eventually, though, these became more reliable and software was developed that meant they found their way into businesses. Eventually the ‘dumb’ terminals connected to a mainframe computer were replaced with microcomputers, each with their own processors and hard drives. However, since this segmented information, issues of data integrity and duplication soon led to the development of networks of server and client microcomputers, and the servers often ended up housed in the computer rooms either alongside or instead of the mainframes and minicomputers, often in 19” rack mounts that resemble rows of lockers.
In 1985, IBM provided more than $30 million in products and support over the course of 5 years to a supercomputer facility established at Cornell University in Ithaca, New York.
This is what the data center looked like in the 1980's and in the immortal words of Doc Brown, "Great Scott!".
Jumping back into the delorean and taking a quick trip forward to 1990's we find the data center is still evolving and microcomputers are now called “servers”. Companies started putting up server rooms inside their company walls with the availability of inexpensive networking equipment.
The biggest change in the nature of data centers comes as a result of the lifting of restrictions on the commercial use of the Internet.
Companies needed fast Internet connectivity and nonstop operation to deploy systems and establish a presence on the Internet and many companies started building very large facilities to provide businesses with a range of solutions for systems deployment and operation.
Enter the time of virtualization development. In 1998 VMware comes onto the scene with a patent for their virtualization platform and on February 8, 1999, VMware introduces the first x86 virtualization product, VMware Virtual Platform, based on earlier research by its founders at Stanford University.
The impact of this is not fully realized at the time but this event will change the future of data centers for ever, (see the timeline below).
The solution was a combination of binary translation and direct execution on the processor that allowed multiple guest OS's to run in full isolation on the same computer with readily affordable virtualization overhead.
Now let's hop back into that delorean and take one last trip to where we find ourselves today.
VMware started this revolution nearly 17 years ago, and is continuing to lead the industry in building out an operating system agnostic virtualization ecosystem to help companies transform their IT environments. Today there is no alternative that compares to VMware's performance, stability, ease of management, security, support, features and vast partner ecosystem.
I guess the big question now is what will the future hold for us in IT? The data center is now moving into the "cloud" with again VMware leading the charge with the idea of One Cloud, Any Application.
We have seen the data center shrink its footprint, hosting multiple virtual servers on an x86 platform. We have seen the transformation of the business computer or workstation with VDI. We have seen the virtualization of the storage with VSAN and VVOLs. We have seen the virtualization of the network with NSX and are seeing the transformation of companies into the cloud with vSphere Hybrid Cloud. We have also, see the transformation of applications and application mobility with containerization and virtualization of the applications.
What will the future hold for those of us lucky enough to bare witness to it? Only time will tell and I for one am off for one last adventure in the delorean to visit the future where Dell owns the world of computing.
I'll let everyone know how the stock does when they go public. See you all in the future.
It can be extremely difficult to secure and maintain security in your production environment. The traditional security model focuses on the perimeter defense but continued security breaches show that this model is not affective.
Firewall can be deployed at each VM, but that proves to be unmanageable. With NSX 6.1 it is possible to micro segment your network, so that only traffic that is allowed can travel through the network between virtual machines.
Traditionally, network segmentation is a function of a physical firewall or router, designed to allow or deny traffic between network segments or tiers. The traditional processes for defining and configuring segmentation are time consuming and highly prone to human error, resulting in a large percentage of security breaches. Implementation requires deep and specific expertise in device configuration syntax, network addressing, application ports and protocols.
Network segmentation is a core capability of NSX. A virtual network can support a multi-tier network environment, meaning multiple L2 segments with L3 segmentation or micro-segmentation on a single L2 segment using distributed firewall rules. These could represent a web tier, application tier and database tier. Physical firewalls and access control lists deliver a proven segmentation function, trusted by network security teams and compliance. Confidence in this approach for cloud data centers, however, has been shaken, as more and more attacks, breaches and downtime are attributed to human error in to antiquated, manual network security provisioning and change management processes.
In a virtual network, network services (L2, L3, ACL, Firewall, QoS etc.) that are provisioned with a workload are programmatically created and distributed to the hypervisor vSwitch. Network services, including L3 segmentation and fire-walling, are enforced at the virtual interface. Communication within a virtual network never leaves the virtual environment, removing the requirement for network segmentation to be configured and maintained in the physical network or firewall.
Two Stage ECMP
Equal cost multi path (ECMP) routing for distributed logical routers and NSX Edges has been added to 6.1. This gives NSX the ability to support ECMP between the Distributed Logical Router (DLR) and the NSX Edges to the physical network. This is limited to 8 ECMP paths. With this new feature you can better utilize bandwidth by way of multiple NSX Edges and their respective uplinks.
Every NSX Edge has the ability to provide load balancing which can provide support for load balancing policies of IP hash, least connection, round robin and URI. NSX 6.1 includes the ability to load balance TCP, UDP and FTP.
