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.

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 is a major tool for our application functionality and job purposes; it helps us at the orchestration level, allowing us to not worry about the entire deployment and service migration.

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 is an excellent choice for organizations already invested in AWS.

What I appreciate about Amazon EKS is the autoscaling feature; when you configure the Kubernetes cluster manually on the VMs and need to add new VMs or if you run out of storage for the VM, you don't have to worry about that with Amazon EKS because it automatically scales the nodes and provides another VM ready for you automatically, which is a great aspect of Amazon EKS.

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.

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.

One area of Amazon EKS that could be improved in the future is related to the behavior of the cluster autoscaler.

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.

Failures from containers running on nodes in AWS data centers can halt our workflows, especially when running in single availability zones.

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.

There are some drawbacks regarding Amazon EKS; pricing can increase as clusters and workloads scale, and there is an initial configuration learning curve.

I find the pricing for Amazon EKS to be quite expensive. The EKS service itself is free, but you will incur costs for the VMs used as nodes in that cluster.
