Canary delivery with Argo Rollout and Amazon VPC Lattice for Amazon EKS

Canary delivery with Argo Rollout and Amazon VPC Lattice for Amazon EKS Solution overview Walkthrough: progressive delivery with VPC Lattice and Argo Rollouts Integration highlights Conclusion About the authors Modern application delivery demands agility and reliability, where updates are rolled out progressively while making sure of the minimal impact on end users. Progressive delivery strategies, such as canary deployments, allow organizations to release new features by shifting traffic incrementally between old and new versions of a service. This allows organizations to first release features to a small subset of users, monitor system behavior and performance in real time, and automatically roll back if anomalies are detected. This is particularly valuable in modern microservices environments running on platforms such as Amazon Elastic Kubernetes Service (Amazon EKS) , where service meshes and traffic routers provide the necessary infrastructure for fine-grained control over traffic routing. This post explores an architectural approach to implementing progressive delivery using Amazon VPC Lattice, Amazon CloudWatch Synthetics , and Argo Rollouts. The solution uses VPC Lattice for enhanced traffic control across microservices, CloudWatch Synthetics for real-time health and validation monitoring, and Argo Rollouts for orchestrating canary updates. The content in this post addresses readers who are already familiar with networking constructs on Amazon Web Services (AWS), such as Amazon Virtual Private Cloud (Amazon VPC) , CloudWatch Synthetics and Amazon EKS. Instead of defining these services, we focus on their capabilities and integration with VPC Lattice. We also build upon your existing understanding of VPC Lattice concepts and Argo Rollouts. For more background on Amazon VPC Lattice, we recommend that you review the post, Build secure multi-account multi-VPC connectivity for your applications with Amazon VPC Lattice , and the collection of resources in the VPC Lattice Getting started guide. The architecture integrates multiple AWS services and Kubernetes-native components, providing a comprehensive solution for progressive delivery: Amazon EKS : A fully managed Kubernetes service to host microservices. VPC Lattice : A service networking layer that enables consistent traffic routing, authentication, and observability across services.
