AppMesh vs VPC Lattice

App Mesh is best suited for ECS, EKS, and EC2 customers who run workloads across different orchestrators and need client-side service mesh functionality, such as traffic resiliency controls (retries, timeouts, connection pooling) and mTLS. App Mesh customers do not mind added complexity of configuration and client-side proxy management implemented as Envoy-based side-cars/proxies.

VPC Lattice is ideal for customers who want to automate connecting micro-services that are distributed across a mix of Kubernetes, native EC2/ASG, and serverless environments (Lambda and Fargate). Additionally, VPC Lattice is best suited to customers who prefer the automation of service discovery, traffic-management, authentication, authorization, and observability across VPCs and accounts without having to deploy and operate sidecar-based service-meshes and also prefer not requiring any prior VPC networking experience in deploying their modern application architectures.
