What is Kubernetes in simple words?
Kubernetes is a portable, extensible, open source platform for managing containerized workloads and services, that facilitates both declarative configuration and automation. It has a large, rapidly growing ecosystem. Kubernetes services, support, and tools are widely available.
What is Kubernetes is used for?
Kubernetes, often abbreviated as “K8s”, orchestrates containerized applications to run on a cluster of hosts. The K8s system automates the deployment and management of cloud native applications using on-premises infrastructure or public cloud platforms.
What is Kubernetes in programming?
Kubernetes ("K8s" for short) is an open source solution for automating the deployment and dynamic scaling of containerized online applications. Kubernetes uses containers, a system in Linux that groups applications into logical units for centralized and secure management. Containers are designed to be ephemeral.
What are the main components of Kubernetes Mcq?
Basic Components of Kubernetes Architecture

- Cloud-controller-manager. ...
- Etcd. ...
- Kubelet. ...
- Kube-proxy. ...
- Kube-controller-manager.
What is a label in Kubernetes?
Labels are key/value pairs that are attached to objects, such as pods. Labels are intended to be used to specify identifying attributes of objects that are meaningful and relevant to users, but do not directly imply semantics to the core system. Labels can be used to organize and to select subsets of objects.
What are the features of Kubernetes?

Why is it called Kubernetes?
The name “Kubernetes” stems from an ancient Greek word for “helmsman,” (someone who steers a ship, like a container ship) which explains the ship wheel logo. The ship wheel has seven sides, in homage to the original name for the project.
What is Kubernetes in DevOps?
DevOps is a software development strategy that combines development and operations teams into a single unit. Kubernetes is an open source orchestration platform designed to help you manage container deployments at scale.
Who uses Kubernetes?

- Google.
- Shopify.
- Udemy.
- Robinhood.
- Slack.
- Delivery Hero.
- Nubank.

What is Kubernetes in cloud?
Kubernetes helps you to build cloud-native microservices-based apps. It also supports containerization of existing apps, thereby becoming the foundation of application modernization and letting you develop apps faster.
What is Kubernetes vs AWS?
Kubernetes is an open source container management and orchestration system. On AWS, you can choose to run and manage Kubernetes infrastructure yourself with Amazon EC2, or use Amazon EKS for a managed, automatically provisioned Kubernetes control plane.
What is VMware Kubernetes?
Kubernetes is an open-source container orchestration platform that automates the management of containerized applications. VMware provides virtualization platforms used by a majority of enterprises.
What is difference between Docker and Kubernetes?
In a nutshell, Docker is a suite of software development tools for creating, sharing and running individual containers; Kubernetes is a system for operating containerized applications at scale. Think of containers as standardized packaging for microservices with all the needed application code and dependencies inside.
Why Kubernetes is used Quora?
Kubernetes contains several tools for service discovery, orchestration, and load balancing, which can be used with Rocket and Docker containers. With the help of Kubernetes, you can easily automate the deployment, scaling as well as scheduling operations of application containers across different node clusters.
What is Kubernetes vs Jenkins?
Jenkins is an open-source automation server that lets you flexibly orchestrate your build, test, and deployment pipelines. Kubernetes Engine is a hosted version of Kubernetes, a powerful cluster manager and orchestration system for containers.
What is Kubernetes container?
Kubernetes, also known as K8s, is an open-source system for automating deployment, scaling, and management of containerized applications. It groups containers that make up an application into logical units for easy management and discovery.
Is Kubernetes cloud or DevOps?
Kubernetes is the operating system of the cloud-native world, providing a reliable and scalable platform for running containerized workloads.
What is CD and CI?
CI and CD stand for continuous integration and continuous delivery/continuous deployment. In very simple terms, CI is a modern software development practice in which incremental code changes are made frequently and reliably.
Why is Kubernetes called K8?
By the way, if you're wondering where the name “Kubernetes” came from, it is a Greek word, meaning helmsman or pilot. The abbreviation K8s is derived by replacing the eight letters of “ubernete” with the digit 8.
Is Kubernetes IaaS or PaaS?
1 Answer. Kubernetes is a powerful open-source container orchestration engine, upon which you could setup PaaS (Platform as a Service). Many companies offer IaaS (Infrastructure as a Service) version of Kubernetes by adding a layer of IaaS below K8. So, Kubernetes is neither IaaS nor PaaS.
What Docker means?
"Docker is an operating system virtualization technology that allows applications to be packaged as containers. This is a very fundamental part of cloud computing, as containerized applications can be run on any type of infrastructure, regardless of the provider.
What is Kubernetes architecture?
Kubernetes is an architecture that offers a loosely coupled mechanism for service discovery across a cluster. A Kubernetes cluster has one or more control planes, and one or more compute nodes.
What tasks are performed by Kubernetes?
Tasks
- 1: Install Tools.
- 2: Administer a Cluster.
- 3: Configure Pods and Containers.
- 4: Monitoring, Logging, and Debugging.
- 5: Manage Kubernetes Objects.
- 6: Managing Secrets.
- 7: Inject Data Into Applications.
- 8: Run Applications.
What is EKS?
Amazon Elastic Kubernetes Service (Amazon EKS) is a managed Kubernetes service that makes it easy for you to run Kubernetes on AWS and on-premises. Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications.
