Which Kubernetes object is most suitable for deploying stateless applications?

• A. Deployment
• B. StatefulSet
• C. DaemonSet
• D. Job

Answer: (A)

Deployments are the go-to way to run stateless applications in Kubernetes. They manage a desired number of replicas through a controlling ReplicaSet, handle rolling updates and rollbacks, and keep pods interchangeable. Because stateless pods don’t rely on stable identity or local storage, you don’t need to preserve a specific pod name or startup order; a Deployment provides a reliable, declarative way to scale, update, and recover your service while keeping a stable service endpoint via a separate Kubernetes Service. The other options serve different needs. StatefulSet is for stateful workloads that require stable network identities and persistent storage. DaemonSet runs a copy of a pod on every node (or a selected subset), which is great for node-level agents but not for general stateless services. Job is for batch tasks that run to completion and finish, not for long-running stateless services.
