Pod Vs Deployment in Kubernetes
Kubernetes has three Object Types you should know about:
- Pods - runs one or more closely related containers
- Services - sets up networking in a Kubernetes cluster
- Deployment - Maintains a set of identical pods, ensuring that they have the correct config and that the right number of them exist.

| POD | Deployment |
| Pods that run a single container | Can run set of pods |
| Updates not possible | Updates are possible |
| Pod crashes not able recover | When create a deployment, replcia set is created(which manages pod) |
| Rollback and rollout is not available | rollout and rollback available |
Pods are the smallest, most basic deployable objects in Kubernetes. A Pod represents a single instance of a running process in your cluster. Pods contain one or more containers, such as Docker containers. When a Pod runs multiple containers, the containers are managed as a single entity and share the Pod's resources.
