Managing complex environments effortlessly while focusing on growth
The most beneficial aspect of Amazon EKS is that it helps manage the Kubernetes master node, so I don't need to maintain the master node, including tasks like upgrading. This allows me to focus on business code. If using services like Fargate, I only need to maintain my workload, simply uploading code that will be deployed to the Kubernetes cluster. This is especially beneficial for startup companies that lack the technical resources to manage the Kubernetes cluster. Furthermore, Amazon EKS allows me to utilize Kubernetes cluster-level expansion. If there’s insufficient resource on a machine, the cluster can automatically expand to add new nodes.

An operational system, similar to Linux where you can run your applications inside containers
With CoreOS, you can run your applications inside containers. For example, if you have an application that needs to run on Linux, you can create and install a container. However, it's important to note that you don't install CoreOS inside a container; CoreOS is the host operating system that manages containers. When you mentioned using Nacula as part of your CI/CD pipeline, it means your application is deployed and managed automatically through the CI/CD process. Containers are used to deploy your application within this pipeline, but CoreOS does not run inside these containers. Instead, CoreOS is the base operating system that supports and manages these containers.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Overall Amazon EKS is a good solution in the industry. The solution can support multi tendencies, and network isolations are the key factors."
"The most valuable feature is the computing speed."
"I can use the autoscaling feature to manage and scale up infrastructure."
"Amazon EKS is a useful solution for modern, cloud-native applications. It offers both horizontal and vertical scaling, which is a big advantage. The tool can also help manage costs while maintaining high availability."
"The solution's performance is good."
"Amazon EKS is very stable, and when properly configured, I rate it ten out of ten."
"EKS has security features that you can't find in competing solutions."
"We do not have to do a lot of administration, such as create virtual machines, or worry about our controllers or nodes going down because the solution is fully managed by Amazon."
"CoreOS Clair's best feature is detection accuracy."
"With CoreOS, you can run your applications inside containers. For example, if you have an application that needs to run on Linux, you can create and install a container. However, it's important to note that you don't install CoreOS inside a container; CoreOS is the host operating system that manages containers."
 

Cons

"I'd like improved traffic handling and additional application details within the system."
"It is very cumbersome to assign permissions to users to interact with a cluster."
"Amazon EKS can be improved by having the maintenance of Kubernetes versions managed better, as everything is handled by the Kubernetes team and possibly a separate team at AWS."
"It's difficult to connect to some of the clusters."
"Amazon EKS needs to improve customer operations and technical support."
"I think the monitoring part and observability part could be improved."
"The initial setup for Amazon EKS is not straightforward. Kubernetes is not an easy technology because there are many technologies in the cluster."
"Amazon EKS is predominately public. However, the government has started to have a lot of interest in Kubernetes and is receiving more education on Kubernetes and Amazon EKS. If we can have the security of Amazon EKS align with the security that is set out by the government it would be much better."
"An area for improvement is that CoreOS Clair doesn't provide information about the location of vulnerabilities it detects."
"It can be improved in its support response. They usually take up to seven days to resolve the issue."
