Designing secure VPCs
Our first stop in this chapter is designing secure VPCs. A VPC is a virtual network dedicated to your AWS account, and its design plays a crucial role in the overall security of your AWS resources. In this section, we will walk you through key security considerations and best practices to ensure your VPCs are securely designed.
Understanding VPCs and their importance
VPCs mark a paradigm shift in network architecture within cloud computing, largely enabled by software-defined networking (SDN). SDN overcomes traditional networking’s physical constraints, such as limited ports and connections, by virtualizing the network stack and separating it from the physical infrastructure. This advancement facilitates granular access control and the creation of numerous subnets for detailed network segmentation. A VPC mimics a conventional network you might operate in a data center but benefits from AWS’s scalable infrastructure and SDN’s flexibility...
