Create a public AWS VPC with CloudFormation

Matthew Casperson's blog post, published on May 9, 2022, elaborates on creating an Amazon Web Services (AWS) Virtual Private Cloud (VPC) with public subnets using a CloudFormation template. It explains the differences between public and private subnets, highlighting that public subnets connect to the internet via an internet gateway, while private subnets do not. The post provides a step-by-step guide to building a VPC with two public subnets, detailing the necessary components such as the internet gateway, route tables, and their associations to direct traffic through the gateway. The process allows instances within the VPC to access the internet and receive public IP addresses for external communications. The post concludes by hinting at the next topic in the series, which will cover creating a VPC with both public and private subnets and a NAT Gateway to enable internet access for private subnet instances.
