SDN

Based on my last post, you’ll understand some of the challenges that are faced with traditional approaches to datacenter networking so let’s get into the high-level conceptual design here of how we might solve one of these problems. Most service providers have or are at least familiar with using MPLS for customer segregation in a WAN scope as I alluded to in my previous datacenter networking article. What we want to do is simplify the provisioning and distribution of subnets to a customer’s virtual environment, all the way up to the WAN....

As of late, I have been getting my feet wet in more networking things - Firstly out of necessity, but it has grown into a genuine area of interest to me. I have a homelab that I like to simulate a production working environment in, so I had a nice opportunity to lab up what a possible multi-tenant IaaS architecture might look like using NSX. NSX fundamentally changes how customer environments for service providers are designed - it moves the complexity away from the physical network and up into the hypervisor management layer, let’s be honest anything that limits touching the physical infra is good, right?...
