  • Introduction to Amazon VPC Lattice

    Amazon VPC Lattice is a fully managed service announced at re:Invent 2022 that simplifies application networking by providing consistent connectivity, security, and monitoring between AWS services, eliminating the need for sidecar proxies.

  • Comparing App Mesh and VPC Lattice

    The post contrasts App Mesh's reliance on Envoy sidecar proxies with VPC Lattice's managed control and data planes. Key differences include Service Networks vs. Service Meshes, Services vs. Virtual Services, Target Groups vs. Virtual Nodes, and Listeners/Rules vs. Virtual Routers/Routes.

  • Architectural and Observability Differences

    VPC Lattice offers built-in CloudWatch metrics, while App Mesh requires manual configuration of the CloudWatch Agent with Prometheus. VPC Lattice natively supports cross-account/VPC access and integrates with the Gateway API and IAM authentication policies.

  • Migration Strategies and Walkthrough

    The guide outlines migration strategies such as in-place and blue/green deployments. It also provides a high-level walkthrough using a sample multi-tiered application on Amazon EKS, detailing steps for configuring the application with App Mesh and then migrating to VPC Lattice resources.
