Containerization is rapidly becoming a standard for managing applications in large production environments.
Containerization allows our development teams to move fast, deploy software efficiently, and operate at an unprecedented scale.
However, managing containers can be a time-consuming task. That's where container orchestration technologies, like Kubernetes, come in.
Kubernetes allows organizations to automatically manage their services and deployment. In this article we'll discuss key reasons why you should adopt Kubernetes.
Containers are changing how companies build and run their applications and infrastructure. As containers become more commonplace, they have ushered in more dynamic infrastructure and given rise to a vast array of supporting technologies. Datadog analyzed more than 1.5 billion containers run by thousands of Datadog customers to reveal which technologies, programming languages, and orchestration practices have gained real-world traction in container environments.
Kubernetes (K8s in short) is an open-source container orchestration platform introduced by Google in 2014. It is a successor of Borg, Google’s in-house orchestration system that accumulated over a decade of the tech giant’s experience of running large enterprise workloads in production. In 2014, Google decided to further container ecosystem by sharing Kubernetes with the cloud native community. Kubernetes became the first graduated project of the newly created Cloud Native Community Foundation (CNCF), an organization conceived by Google and the Linux Foundation as the main driver of the emerging cloud native movement.
The platform’s main purpose is to automate deployment and management (e.g., update, scaling, security, networking) of containerized application in large distributed computer clusters. To this end, the platform offers a number of API primitives, deployment options, networking, container and storage interfaces, built-in security, and other useful features.

Kubernetes, at its basic level, is a system for running and coordinating containerized applications across a cluster of machines. It is a platform designed to completely manage the life cycle of containerized applications and services using methods that provide predictability, scalability, and high availability.
The central component of Kubernetes is the cluster. A cluster is made up of many virtual or physical machines that each serve a specialized function either as a master or as a node. Each node hosts groups of one or more containers (which contain your applications), and the master communicates with nodes about when to create or destroy containers. At the same time, it tells nodes how to re-route traffic based on new container alignments.
Some of its capabilities include:
Kubernetes provides much more beyond the basic framework, enabling users to choose the type of application frameworks, languages, monitoring and logging tools, and other tools of their choice. Although it is not Platform as a Service, it can be used as a basis for a complete PaaS.
In a few years, it has become a highly popular tool and one of the biggest success stories on the open-source platform.
Many cloud services offer a Kubernetes-based platform or infrastructure as a service (PaaS or IaaS) on which Kubernetes can be deployed as a platform-providing service. Many vendors also provide their own branded Kubernetes distributions.

Kubernetes has some great features that allow you to deploy applications faster with scalability in mind:
Kuberntetes is vendor-agnostic. Many public cloud providers not only serve managed Kubernetes services but also lots of cloud products built on top of those services for on-premises application container orchestration. Being vendor-agnostic enables operators to design, build, and manage multi-cloud and hybrid cloud platforms easily and safely without risk of vendor lock-in. Kubernetes also eliminates the ops team's worries about a complex multi/hybrid cloud strategy.
Kubernetes is great, but, as anything in the world, it’s not perfect. Transitioning to Kubernetes is associated with numerous challenges which must be addressed by companies seeking to adopt it. Here’s our list of cons and challenges.
Still, despite the cons, Kubernetes remains a great option for container orchestration.
Containerization allows our development teams to move fast, deploy software efficiently, and operate at an unprecedented scale. To organize container deployments, organizations use container orchestration system like Kubernetes.
Kubernetes' main function is to automate deployment and management (e.g., update, scaling, security, networking) of containerized application in large distributed computer clusters.
It gives you complete control over container orchestration, enabling you to deploy, maintain and scale application containers across a cluster of hosts.
