3 Ways Organizations Use NSX for Application Continuity
Five example customers using NSX to enable application continuity for their business
No one looks forward to data center outages. Not the business leaders who fear revenue loss from applications being down, nor the heroic IT admin whose pager is going off at 3:00 AM. Therefore many critical data centers have a sister location and some form of a disaster recovery plan, should something go awry. At the same time, infrastructure teams are under pressure to be more agile and more responsive to the business, across the board, while still lowering costs and making the most out of what they already have. So what exactly happens in the case of a disaster?
The Ponemon Institute reports the average cost of a data center outage to be $740,357, but with massive variance – some known examples going up to $150 million. As businesses move to accelerate to keep up with changes in their industry, each minute lost to downtime can have an impact not only on company resources but also on brand reputation. This is why enabling business continuity or application continuity in a manner that doesn’t require new infrastructure is vital. VMware NSX can offer companies a competitive edge through networking and security Continue reading

Time to Overhaul Your Campus Network
Over the last few years cloud service providers have steadily adopted white-box Ethernet switches and modern, flexible Network Operating Systems into their ecosystems. Mega data center operators, such as Google, Amazon, and Microsoft, have replaced their proprietary gear with white boxes in their production environments. The major benefit of this paradigm shift is significantly reduced CapEx and OpEx, a more reliable environment, and customized traffic flows for efficiency. According to IDC, the worldwide ODM direct Ethernet switch (white box) market was $677 million in 2016 and is expected to exceed $900 million in 2017. That’s a growth rate of 33%, and the trend is accelerating.
The shift in white-box adoption started as early as 2012, but has been limited to data centers for many reasons. Even though Enterprise IT executives are motivated to adopt white-boxes, the migration has been slow and challenging. Essentially, the Enterprise network is distinctly different from data center network in many ways.
- The data center network is usually homogeneous, while the Enterprise network is heterogeneous. Typically, Enterprises require a variety of speeds ranging from 100Mbps to 100Gbps, and run over different cables, including various types of copper and fiber. The increasingly deployed Power over Ethernet (PoE) Continue reading

How well can you know each of these four systems? Can you actually know them in fine detail, down to the last packet transmitted and the last bit in each packet? Can you know the flow of every packet through the network, and every piece of information any particular application pushes into a packet, or the complete set of ever changing business requirements?
Obviously the answer to these questions is no. As these four components of the network combine, they create a system that suffers from combinatorial explosion. There are far too many combinations, and far too many possible states, for any one person to actually know all of them.
How can you reduce the amount of information to some amount a reasonable human can keep in their minds? The answer—as it is with most problems related to having too much information—is abstraction. In turn, what does abstraction really mean? It really means you build a model of the system, interacting with the system through the model, rather than trying to keep all the information about every subsystem, and how the subsystems interact, in your head. So for each subsystem of the entire system, you have a model you are Continue reading
