[Pods]
The basic execution unit in Kubernetes is a pod. A pod represents a single instance of a containerized application. You can think of a pod as a container or a group of containers that are deployed together on a single node in the cluster.
[Deployments]
A Deployment is a high-level object that manages a ReplicationController or ReplicaSet and provides declarative updates to the application.
With a Deployment, you can specify the desired state of your application and the Deployment will ensure that the application is running in that state.
[Replication Controllers] or ReplicaSet
A Replication Controller ensures that a specified number of pod replicas are running at any given time. If any pods fail or are deleted, the Replication Controller will create new pods to replace them. This helps to ensure the availability of your application.
[StatefulSets]
A StatefulSet is used to manage stateful applications. It provides features such as persistent storage and network identifiers for its pods. This is useful if you have applications that need to maintain state across restarts or need to communicate with each other using stable network addresses.
[Services]
A Service is an abstract way to expose a set of pods as a network service. It can be used to load balance traffic to a group of pods. For example, if you have multiple instances of a web application running in different pods, you can use a Service to expose the application to external traffic.
[DaemonSets]
A DaemonSet ensures that a specific pod is running on all nodes in the cluster or on a subset of nodes, as specified. This is useful for deploying applications that need to run on every node in the cluster, such as a logging agent or a monitoring agent.
[Jobs]
A Job creates one or more pods and ensures that a specified number of them successfully terminate. Jobs are used to running batch processes or perform one-time tasks.
