Adrian Cantrill’s SAA-C02 course, 90 minutes: https://learn.cantrill.io/ ‘Custom VPC’s’ through ‘Implement Multi-tier subnets’ demo
Going through the process of creating a virtual private cloud (vpc) and then creating a group of subnets using CIDR block allocation was a great learning experience. My networking studies have been put on the back burner for now to focus on AWS exclusively, but it was great to draw on what I have learned.
The context for networking concepts is a little nuanced in a cloud environment. It’s basically the same information, but the application is modified a bit in the cloud environment vs. a regular physical network. I will be reiterating on this shortly, and making sure it’s really ingrained.
