Since AWS released Transit Gateways almost a year and a half ago, what is the point of a transit VPC concept?
Also, do we still need to study this old architecture for this exam?
Yep Transit VPCs are still a thing….they are more an architectural arrangement of VPC components versus a black box thing like Transit Gatway. They are still in use in lots of architectures either from a legacy standpoint or that’s just how the landscapes evolved. From an exam standpoint, I’d just have an understanding of the when’s and why’s of Transit VPC and Transit Gateway.
