Kubernetes
Kubernetes is a tool that helps companies manage their software applications in a modern way. Think of it like a smart traffic controller for computer programs - it makes sure applications run smoothly, handles sudden increases in user traffic, and automatically fixes problems. Companies use Kubernetes because it helps them run their applications reliably and scale them up or down based on need. Similar systems include Docker Swarm and OpenShift. When you see Kubernetes (sometimes shortened to K8s) on a resume, it means the person has experience with cloud computing and managing modern applications at scale.
Examples in Resumes
