[@Thiru-zt5lw]

kubernatis , can we place inside the aws? docker

[@Thiru-zt5lw]

Yes, Kubernetes can be run inside Amazon Web Services (AWS) and can be used to manage Docker containers. Kubernetes provides an orchestration layer for Docker containers, making it easier to manage and scale large-scale applications. AWS offers several options for running Kubernetes, including managed services like Amazon Elastic Kubernetes Service (EKS) and self-managed options like EC2 instances with kubeadm. With the combination of AWS and Kubernetes, you can build, deploy, and manage highly scalable and resilient applications. i got the information from chatgpt, can you elloraborate more about it

[@Javatechie]

Yes I will upload about EKS soon
