Why AWS Teams Are Migrating from ECS to EKS
Amazon ECS is a solid container orchestrator, but teams outgrow it when they need advanced scheduling, a richer ecosystem, or multi-cloud portability. Amazon EKS gives you the full power of Kubernetes while staying within the AWS ecosystem.
Our EKS consulting team has migrated 30+ ECS clusters to EKS, handling every detail: Task Definition conversion to K8s manifests, ALB target groups to Ingress resources, ECS Service Connect to Kubernetes service discovery, and Task Roles to IRSA.
We use Terraform to provision production-grade EKS clusters with Karpenter autoscaling, and implement GitOps workflows for automated, auditable deployments.
ECS vs EKS: What Changes
Key differences when migrating to Kubernetes on AWS
Moving from ECS to EKS unlocks the full Kubernetes ecosystem while retaining deep AWS integration.
AWS ECS
- Task Definitions for container config
- ECS Service Connect & Cloud Map
- ALB target groups per service
- Task Roles (limited to task level)
- ECS-specific tooling only
- AWS-locked container orchestration
AWS EKS (Kubernetes)
- Kubernetes Deployments with Helm charts
- Kubernetes Services & DNS-based discovery
- Ingress controller with path-based routing
- IRSA with fine-grained pod-level IAM
- 1000+ CNCF ecosystem tools & operators
- Portable workloads across any cloud
ECS to EKS Migration Services
End-to-end AWS container migration from ECS to Kubernetes
Task Definition to K8s Manifest Conversion
Convert ECS Task Definitions—container definitions, resource limits, environment variables, and secrets—to Kubernetes Deployments, Pods, and Helm charts. We ensure parity in resource allocation, health checks, and logging configurations.
- Task Definition analysis & conversion
- Resource request/limit mapping
- Environment variable & secret migration
- Sidecar pattern implementation
ALB to Kubernetes Ingress Migration
Migrate from ECS Service Connect and ALB target groups to Kubernetes Ingress with AWS Load Balancer Controller. We configure path-based routing, TLS termination, and health checks using native EKS integrations.
- ALB target group to Ingress mapping
- AWS Load Balancer Controller setup
- TLS certificate migration via ACM
- Path & host-based routing config
IAM & Security Migration
Migrate ECS Task Roles and execution roles to IAM Roles for Service Accounts (IRSA) on EKS. We implement Kubernetes RBAC, Pod Security Standards, and network policies for defense-in-depth security.
- Task Role to IRSA conversion
- Kubernetes RBAC implementation
- Pod Security Standards setup
- Network policy configuration
EKS Cluster & Infrastructure Setup
Provision production-grade EKS clusters using Terraform with managed node groups, Karpenter autoscaling, VPC networking, and observability stack. We configure the cluster to match or exceed your ECS environment's capabilities.
- EKS cluster provisioning via Terraform
- Karpenter node autoscaling
- VPC & subnet configuration
- Observability stack deployment
ECS Concepts to EKS Equivalents
Every ECS construct has a Kubernetes counterpart
Task Definitions to Pods
ECS Task Definitions become Kubernetes Pod specs within Deployments, with identical resource limits and container configurations.
Services to Deployments
ECS Services translate to Kubernetes Deployments with ReplicaSets for scaling, self-healing, and rolling updates.
ALB to Ingress Controller
Application Load Balancers are replaced by the AWS Load Balancer Controller with Ingress resources for routing.
Task Roles to IRSA
IAM Task Roles convert to IAM Roles for Service Accounts (IRSA) for fine-grained, pod-level AWS permissions.
Parameter Store to Secrets
SSM Parameter Store and Secrets Manager integrate via External Secrets Operator for Kubernetes-native secret management.
CloudWatch to Prometheus
ECS CloudWatch metrics are replaced by Prometheus and Grafana for deeper container-level observability.
Our ECS-to-EKS Migration Process
A proven approach for AWS container migration
-
ECS Environment Assessment
Audit all ECS services, Task Definitions, networking, IAM roles, and integrations. Map dependencies between services, identify stateful workloads, and build a prioritized migration roadmap.
-
EKS Cluster Provisioning
Deploy production-grade EKS clusters via Terraform with Karpenter autoscaling, VPC networking, IRSA, and observability stack. Configure namespaces, RBAC, and network policies.
-
Service Migration & Testing
Convert Task Definitions to Kubernetes manifests and Helm charts. Migrate ALB routing to Ingress, Task Roles to IRSA, and secrets to External Secrets Operator. Run parallel validation.
-
Traffic Cutover & ECS Decommission
Execute zero-downtime traffic shift from ECS to EKS using Route 53 weighted routing or ALB target group switching. Validate performance, then decommission ECS services.

ECS to EKS Migration FAQs
Common questions about migrating from ECS to EKS
Why migrate from ECS to EKS?
EKS provides greater portability (avoiding AWS lock-in), a richer ecosystem of CNCF tools, advanced scheduling capabilities, and better multi-cloud strategies. Teams gain access to Helm, ArgoCD, service mesh, and thousands of Kubernetes operators. Our EKS consulting team helps you leverage these advantages fully.
How do you convert ECS Task Definitions to Kubernetes manifests?
We analyze each Task Definition—container images, CPU/memory limits, port mappings, environment variables, secrets, volumes, and health checks—and create equivalent Kubernetes Deployments or StatefulSets. We package everything into Helm charts for versioned, repeatable deployments and integrate with ArgoCD for GitOps.
How do you handle ECS Service Discovery during migration?
ECS Service Connect and Cloud Map entries are replaced with Kubernetes Services (ClusterIP, NodePort, LoadBalancer) and DNS-based service discovery. During migration, we run services in parallel and use DNS-level traffic shifting to ensure zero-downtime cutover.
What about ECS services using Fargate?
EKS supports Fargate profiles for serverless pod execution, so your Fargate workloads can continue running serverlessly on EKS. Alternatively, we can migrate to managed node groups with Karpenter for more flexibility and lower costs at scale.
How long does an ECS to EKS migration take?
Small environments (5-10 services) take 4-6 weeks. Medium environments (10-30 services) take 6-12 weeks. Large enterprise migrations with complex networking, databases, and compliance requirements span 3-6 months with phased rollouts. Contact us for a detailed assessment.
