This article
explains the similarities between a LISP/VXLAN based Campus Fabric and AWS
Virtual Private Cloud (VPC) from the Intra-Subnet Control-Plane and Data-Plane
operation perspective. The AWS VPC solution details are not publicly available
and the information included in this article is based on the author's own study
using publically available AWS VPC documentation.
There are two main reasons for writing this document:
First, Cisco SDA is an on-prem LAN model while the AWS VPC is an off-prem DC solution. I wanted to point out that these two solutions, even though used for very different purposes, use the same kind of Control-Plane operation and Data-Plane encapsulation and are managed via QUI. This is kind of my answer to ever going discussion about is there DC-networks, Campus-networks and so on, or is there just networks.
Second, my own curiosity to understand the operation of AWS VPC.
I usually start by introducing the example environment and then explaining the configuration, moving to Control-Plane operation and then to Data-Plane operation. However, this time I take a different approach. This article first introduces the example environment but then the Data-Plane operation is discussed before Control-Plane operation. This way it is easier to understand what information is needed and how that information is gathered.
