This video introduces Amazon VPC Lattice, a new EC2 networking service that simplifies connecting, securing, and monitoring service-to-service communication. The presenters discuss how VPC Lattice addresses key challenges in modern application architectures, including connectivity across multiple VPCs and accounts, consistent security controls, and observability. They explain how VPC Lattice provides a unified solution for both network connectivity and application-layer proxy functionality, working seamlessly across different compute platforms like EC2, containers, and serverless. The service enables administrators to enforce security policies while giving developers flexibility to focus on business logic. Key features include service networks, authentication and authorization via IAM integration, and simplified traffic management. The presentation covers common use cases like multi-cluster Kubernetes environments and implementing fine-grained access controls.
