The value of Amazon EKS for us is due to our microservice-level architecture, where we need to automate and have a fast, scalable application, allowing us to directly configure the Amazon EKS cluster in the application, which will make it very easy to run our application smoothly and scalably.

By integrating AWS IAM roles with Amazon EKS service accounts, we can leverage other services from Amazon EKS such as S3, Secrets Manager, or EC2, and the concept of IRSA helps us integrate with external services of the Amazon EKS cluster easily.

The major advantages include reduced time, high availability, and scalability, and from a security perspective, AWS has multiple security layers including IAM roles, different ILBs, ingress controllers, and multiple security features.

Amazon EKS's scalability is brilliant, as you can easily scale from zero nodes all the way up to the tens of thousands, probably even higher, without really having a bottleneck in terms of scalability.

The most valuable aspect of Amazon EKS, from my perspective as someone who has worked with on-premises solutions, is that it eliminates manual setup requirements, handles everything automatically, and removes the effort of manual configuration that is necessary with on-premises solutions.

Amazon EKS doesn't have that feature to read the dynamic one and consider that the password has changed overnight; there is no functionality from the provider to see the changes and then restart the pod or fetch the new value.
Fedir Plotnikov - PeerSpot reviewer

What could be improved in Amazon EKS is the documentation. It's pretty dynamic, moving too fast, and sometimes the documentation doesn't reflect the migration between changes, especially if you use some non-native vendor enterprise components and CRDM modules.

We have not automated patches to be applied for the Amazon EKS cluster because it will resolve live production services.

The costing perspective could be improved. With normal on-premises servers using Kubernetes services, the costing might be slightly higher compared to other Kubernetes vendors.

While exploring options for potential Amazon EKS downtime scenarios, we found Velero to be the only backup option, which is both overwhelming and complicated to set up.
