GKE
Google Kubernetes Engine (GKE) is a service by Google Cloud that helps companies run and manage their applications in the cloud. Think of it as a smart system that automatically handles how computer programs are distributed and run across multiple servers. It's like having a virtual IT team that makes sure applications run smoothly, can handle more users when needed, and recover quickly if something goes wrong. Companies use GKE because it makes it easier to manage complex applications without needing to worry about the underlying technical details. Similar services include Amazon's EKS or Microsoft's AKS.
