The Elastic Container Service now leverages VPC Lattice for built‑in deployment patterns, allowing customers to shift traffic more safely during updates.

Amazon Elastic Container Service (ECS) now integrates with AWS VPC Lattice, delivering native support for blue‑green, linear, and canary deployment strategies.

What VPC Lattice Brings to ECS

VPC Lattice provides a managed service mesh that routes traffic at the network layer, eliminating the need for separate load balancers or custom routing logic when updating containerized applications.

By embedding VPC Lattice directly into ECS task definitions, customers can declare deployment patterns in their service configuration, and the platform automatically handles traffic shifting, health checks, and rollback if needed.

Supported Deployment Patterns

  • Blue‑green: Deploy a new version alongside the current one and switch traffic once health checks pass.
  • Linear: Incrementally move a fixed percentage of traffic to the new version over a defined schedule.
  • Canary: Gradually increase traffic to the new version while monitoring key metrics.

These patterns are defined using simple JSON fields in the ECS service definition, making it easy to adopt best‑practice deployment workflows without additional tooling.

Benefits for Developers and Operators

The integration reduces operational overhead by removing the need to manage separate service‑mesh components or external traffic‑routing scripts. It also improves safety, as traffic can be rolled back instantly if the new version fails health checks.

Because VPC Lattice operates at the VPC level, traffic never leaves the private network, preserving security posture and reducing latency compared with internet‑facing load balancers.

Getting Started

To enable the feature, users update their ECS service definition to include a deploymentController of type VPC_LATTICE and specify the desired rollout strategy. The AWS CLI and SDKs have been updated to accept these parameters, and the AWS Management Console now shows a dedicated UI for configuring rollout settings.

Existing services can be migrated by adding the new configuration and performing a rolling update, allowing a seamless transition without downtime.
