NSX and Load Balancers

During VMworld a lot of announcements were made, one that may not have been as well advertised is F5’s integration with NSX. Load balancing isn’t always looked at as a sexy technology and at the end of the day may not be because when it works it just works.  But there are use cases for load balancing that go beyond a single web site with multiple servers hosting it or round robin load balancing VPN concentrators.

If this doesn’t look familiar you aren’t flying to the moon

Active\Active datacenters and workloads require some level of load balancing, and saying you are going to cloud burst without understanding how the DNS and network will respond or be routed is like saying you are going to fly to the moon with out understanding the premise of escape velocity.

Virtualize all the things means storage too

Remember when we started virtualizing servers? The problem we were solving was under-utilization and hardware abstraction. I guess I could go back to the first GUI OS’ and the hardware abstraction layer (HAL) but let’s stay on topic for once.

So we virtualized servers in order to get better utilization, reduce operating costs, add redundancy and allow for mobility across vendor platforms. Today we are seeing storage vendors try and tackle the same problem. EMC is doing this with ViPR, NetApp has vFiler, HP has StoreServ, there are also smaller startups like Pernix and Atlantis trying to do similar things. Even VMware to some extent is trying to virtualize the storage layer with VSAN.
