AWS Subnets
AWS Subnets are logical subdivisions of an Amazon Virtual Private Cloud (VPC) that allow you to segment network resources for security, performance, and organization. They enable you to isolate instances, control traffic flow, and assign IP address ranges within a VPC. Subnets can be public (accessible from the internet) or private (restricted access), facilitating secure and scalable cloud architectures.
Developers should learn AWS Subnets when designing cloud infrastructure on AWS to implement network segmentation, enhance security through isolation, and optimize resource placement. Use cases include deploying web servers in public subnets with internet access, placing databases in private subnets for protection, and managing multi-tier applications with distinct network layers for compliance and performance.
