Adrian Cantrill’s SAA-C02 course, 75 minutes: https://learn.cantrill.io/ ‘VPC Sizing and Structure – parts 1 and 2’, ‘Custom VPCs’, ‘VPC Subnets’ sections.
I learned about the importance of the VPC in the overall architecture of a well-architected solution. I looked at CIDR blocks, VPC sizing, default VPC’s, Default and Dedicated Tenancy, and using DNS via Rte 53 in VPC’s, along with other topics.
Learning this material is strengthening my resolve to continue focusing on cloud networking security as my ultimate goal. However, now I am building step-by-step instead of trying to learn everything at once.
