In this session, we will review the new AWS Transit Gateway and new networking features. We compare AWS Transit Gateway and Transit VPCs and discuss how to architect your accounts and VPCs. This session will be helpful if the developers have been let loose, and you are planning lots of VPCs or accounts. How should you connect them; what limits do you need to be aware of; and how does routing work with many VPCs? We dive into the details of recent launches and how to work with concepts like Transit VPCs, account strategies, scaling services, using firewalls, and direct connect gateways to solve problems of many VPCs.
