Amazon EKS in Production: Feedback and Complete Evaluation

TL;DR: Amazon EKS dominates the managed Kubernetes market with 30% market share and 2 million customers (Atmosly). This feedback details the advantages, disadvantages, and best practices for deploying EKS in production. Verdict: a robust solution that requires solid Kubernetes administration expertise.

Cloud operations engineers who want to master EKS follow the LFS458 Kubernetes Administration training.

Why collect Amazon EKS feedback before migrating?

Amazon EKS represents the default choice for many companies migrating to Kubernetes on AWS. With 82% of container users running Kubernetes in production (CNCF Annual Survey 2025), the question is no longer "should we adopt Kubernetes?" but "which platform to choose?".

Collect field feedback before any decision. Marketing benchmarks don't reflect operational reality. This article synthesizes Amazon EKS feedback from teams that have been operating clusters in production for several years.

Key takeaway: A Cloud operations engineer with CKA Kubernetes certification identifies AWS integration pitfalls 3x faster than a self-taught administrator.

What are the advantages of EKS in production?

Native integration with the AWS ecosystem

EKS natively integrates with over 200 AWS services. IAM, VPC, ALB, CloudWatch, Secrets Manager: each component works without complex configuration.

Configure IRSA from day one. This feature eliminates static credentials in your pods:

apiVersion: v1
kind: ServiceAccount
metadata:
name: my-app
annotations:
eks.amazonaws.com/role-arn: arn:aws:iam::123456789:role/my-app-role

Managed control plane reliability

AWS manages the Kubernetes control plane with a 99.95% SLA. Security updates are applied automatically without service interruption.

According to Spectro Cloud State of Kubernetes 2025, 80% of organizations manage an average of 20+ clusters. EKS simplifies this multi-cluster management through tools like eksctl.

Key takeaway: The managed control plane eliminates 60% of daily administration tasks related to etcd, kube-apiserver, and kube-scheduler.

Fargate ecosystem for serverless

EKS on Fargate eliminates node management. You deploy pods without provisioning EC2 instances:

eksctl create cluster --name prod-cluster \
--region eu-west-1 \
--fargate

This approach suits unpredictable workloads where traditional autoscaling lacks responsiveness. To dive deeper into deployment strategies, explore our Kubernetes tutorials and practical guides.

Amazon EKS feedback: Disadvantages to anticipate

Time to first attack

EKS clusters face their first attack within 28 minutes of creation (Wiz Kubernetes Security Report 2025). This finding requires a proactive security posture.

Enable Network Policies immediately. By default, all pods communicate with each other:

apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
name: deny-all-ingress
spec:
podSelector: {}
policyTypes:
- Ingress

Cost model complexity

EKS charges $0.10/hour per cluster (about $73/month) plus EC2 or Fargate resources. Costs explode without rigorous FinOps governance.

According to nOps FinOps Statistics, 89% of IT leaders plan to increase their cloud budgets in 2025 for AI workloads. This budget pressure reinforces the importance of solid EKS expertise.

Vendor lock-in dependence on AWS

Integrated services (ALB, IRSA, EBS CSI) create strong adhesion to AWS. Migration to GKE or AKS requires rewriting infrastructure configurations.

Key takeaway: Document each AWS-specific integration. Use Helm or Kustomize abstractions to facilitate potential migration.

How to evaluate EKS against managed alternatives?

EKS market positioning

EKS holds 30% of the managed Kubernetes market with 2 million customers (Atmosly). This dominant position is explained by companies' existing AWS ecosystem.

When to choose EKS over GKE or AKS?

Choose EKS if your AWS infrastructure exceeds 50% of your workloads. Native integration justifies the control plane cost.

Avoid EKS if you're starting with Kubernetes without a certified team. GKE offers a more guided experience with Autopilot.

To dive deeper into this comparison, read our analysis Google GKE for developers.

Is Docker Swarm still an alternative?

According to The Decipherist, 96% of organizations use or evaluate Kubernetes versus ~24% for Docker Swarm. The gap is widening.

Docker Swarm suits small teams with simple needs. As Portainer Blog states: "Docker Swarm: 1 command setup (docker swarm init); Kubernetes: more complex multi-step installation."

Our guide Kubernetes vs Docker Swarm: which orchestrator to choose details the decision criteria.

What Cloud operations engineer profile to manage EKS?

Required technical skills

A Cloud operations engineer with CKA Kubernetes certification masters the essential fundamentals:

• Control plane and node administration
• Network configuration (CNI, Network Policies, Service Mesh)
• Storage management (PV, PVC, StorageClass)
• Security (RBAC, Pod Security Standards, Secrets)
• Troubleshooting (kubectl debug, logs, events)

As The Enterprisers Project points out: "Anybody can learn Kubernetes. With abundant documentation and development tools available online, teaching yourself Kubernetes is very much within reach."

CKA certification value

The CKA exam validates 2 hours of practical skills with a passing score of 66% (Linux Foundation). 104,000 people have taken this exam, with 49% year-over-year growth (CNCF Training Report).

A testimonial from TechiesCamp CKA Review: "The CKA exam tested practical, useful skills. It wasn't just theory - it matched real-world situations you'd actually run into when working with Kubernetes."

Key takeaway: CKA certification is valid for 2 years (Linux Foundation). Plan your recertification.

The average salary for a Kubernetes developer reaches $152,640/year globally (Ruby On Remote).

How to secure an EKS cluster from day one?

EKS security checklist

Apply these measures before any production deployment:

1. Enable audit logging to CloudWatch or S3
2. Configure Pod Security Standards in enforce mode
3. Deploy restrictive Network Policies
4. Use IRSA to eliminate static credentials
5. Scan images with ECR Image Scanning or Trivy

# Enable audit logging
aws eks update-cluster-config \
--name prod-cluster \
--logging '{"clusterLogging":[{"types":["api","audit","authenticator","controllerManager","scheduler"],"enabled":true}]}'

EKS production pros and cons: Security summary

71% of Fortune 100 companies run Kubernetes in production (CNCF Project Journey Report). These organizations apply strict security standards that you must replicate.

What training to master EKS in production?

Recommended path for Cloud operations engineers LFS458 Kubernetes Administration training

The LFS458 Kubernetes Administration training covers essential skills in 4 days (28h):

• Cluster installation and configuration
• Network and storage management
• Security and access control
• Troubleshooting and maintenance

This training directly prepares for CKA certification, essential for operating EKS in production with confidence.

Complete with Kubernetes security

After CKA, the LFS460 Kubernetes Security Fundamentals training (4 days) deepens critical security aspects for EKS.

Chris Aniszczyk, CNCF CTO, states: "Kubernetes is no longer experimental but foundational. Soon, it will be essential to AI as well." (CNCF State of Cloud Native 2026)

Key takeaway: Investing in Kubernetes training generates measurable ROI in incident reduction and deployment acceleration.

As TealHQ Kubernetes DevOps Guide recommends: "Don't let your knowledge remain theoretical - set up a real Kubernetes environment to solidify your skills."

Final verdict: Is EKS right for your organization?

Summary of EKS production pros and cons

Recommendation: EKS excels for organizations already invested in AWS with trained teams. Without CKA certification on the team, plan for 3-6 months of skill development.
