What are the components of Kubernetes?
Main components of Kubernetes: 1 Cluster: A control plane and one or more compute machines, or nodes. 2 Control plane: The collection of processes that control Kubernetes nodes. This is where all task assignments originate. 3 Kubelet: This service runs on nodes and reads the container manifests and ensures the defined containers are started and running. 4 Pod: A group of one or more containers deployed to a single node. All containers in a pod share an IP address, IPC, hostname, and other resources.

What Is A Container In Cloud Computing?
A container is an executable unit of software that helps package and run software code, libraries, dependencies, and other parts of an application so that it can work reliably in different computing environments.
Containers Vs. Microservices
Containers refer to software packages that contain everything an application unit needs to function. Microservices refers to the technology that makes it possible to split up a large (monolithic) application into smaller, multiple services, each performing a specific function.
Containers Vs. Virtual Machines
Containers mount on top of a physical server's hardware, sharing a single operating system. At the same time, virtual machines (VM) use software, firmware, or hardware to create multiple virtual machines running different operating systems on top of a single host.
Container Use Cases
Organizations use containers for a variety of reasons. The following are several uses of containers in cloud computing.
What Is Container Orchestration?
Container orchestration is the automated process of coordinating and organizing all aspects of individual containers, their functions, and their dynamic environments. Container deployment and scaling, networking, and maintenance are all aspects of orchestrating containers.
The Benefits Of Container Orchestration
Orchestration simplifies container management. In addition, orchestration tools help determine which hosts are the best matches for specific pods. That further eases your engineers’ job while reducing human error and time used. Orchestrating also promotes optimal resource usage.
Managing Your Container Costs
You can deploy and manage containerized apps at scale with containers. A container orchestration platform can help you do this with greater precision and automatically reduce errors and costs. It can also help you provide a reliable service to your users.
What Cluster Management Functions do Schedulers Provide?
Scheduling is often tied to cluster management functions because both functions require the ability to operate on specific hosts and on the cluster as a whole.
Why do schedulers interact with each host?
In order to run and manage containers on hosts throughout the cluster, the scheduler must interact with each host’s individual init system. At the same time, for ease of management, the scheduler presents a unified view of the state of services throughout the cluster. This ends up functioning like a cluster-wide init system. For this reason, many schedulers mirror the command structure of the init system’s they are abstracting.
Why is cluster management important?
Cluster management is closely tied to scheduling because the scheduler must have access to each host in the cluster in order to schedule services. For this reason, the same tool is often used for both purposes. In order to run and manage containers on hosts throughout the cluster, the scheduler must interact with each host’s individual init system.
Why do schedulers provide override mechanisms?
Schedulers typically provide override mechanisms that administrators can use to fine-tune the selection processes to satisfy specific requirements. For instance, if two containers should always run on the same host because they operate as a unit, that affinity can often be declared during the scheduling.
What is scheduling in a host?
In this environment, “scheduling” refers to the ability for an administrator to load a service file onto a host system that establishes how to run a specific container. While scheduling refers to the specific act of loading the service definition, in a more general sense, schedulers are responsible for hooking into a host’s init system to manage services in whatever capacity needed.
What is cluster management?
Cluster management is the process of controlling a group of hosts. This can involve adding and removing hosts from a cluster, getting information about the current state of hosts and containers, and starting and stopping processes. Cluster management is closely tied to scheduling because the scheduler must have access to each host in ...
What is orchestration in a network?
Orchestration is a broad term that refers to container scheduling, cluster management, and possibly the provisioning of additional hosts.
