When you order a new product, you welcome it with open arms once it arrives. Next, you unbox it and ensure that the package is intact. For a well-packaged product, you can’t wait to open its protective casing to dive deeper into its inner workings. Examining the individual components, understanding how to install them, and exploring how to use the product provide valuable insights into its design and functionality. In the same way, we aim to delve into Amazon EKS by uncovering its core components, analyzing how they are interconnected, and exploring the configuration options available for cluster operators. This approach will offer a clear understanding of EKS’s architecture and how to tailor it to meet diverse application needs. Specifically, we will cover the EKS architecture and the three cluster network access control options available for cluster operators. This should lead us into security discussions and the implications of cluster network access control use cases.
