Implementing a multi-tenant networking platform with NSX

So we have covered the typical challenges of a multi-tenant network and designed a solution to one of these, it’s time to get down to the bones of it and do some configuration! Let’s implement it in the lab, I have set up an NSX ESG Cust_1-ESG and an NSX DLR control VM Cust_1-DLR with the below IP configuration: I have also enabled OSPF as a NSSA (area 51) between the ESG and the DLR control VM and specified to redistribute connected routes attached to the DLR:...

Designing a networking platform for IaaS multi-tenancy

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....

Multi-tenant network challenges

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?...

Designing a modern multi-tenant DC network

Over the last 12 months my posting has been dialled back, this isn’t for lack of wanting or ideas, mainly a lack of time and mental bandwidth. Reason being, I have been designing and implementing a new cloud platform (namely “STC” ↗) for my employer, Novosco - as with any new service or product this requires an element of discretion - but now is the time to let slip some of the detail on what makes the service tick!...
