WHAT IS KUBERNETES AND WHY IT IS USED PORTABLE
Their immutability and abstraction make them portable across environments, whether it’s a physical or virtual machine, on-premises, in a data center, or in the public cloud, regardless of the underlying platform or OS. These packages, known as container images, are immutable, and they are abstracted from the environment on which they run.
WHAT IS KUBERNETES AND WHY IT IS USED SOFTWARE
What are containers, and why are they so hot?Ī container is a unit of software that packages application code and its dependencies together, creating a small, self-contained, and fully functional environment to run a workload (app, service), isolated from the other applications running on the same machine. The challenge at the time was to manage containers at scale in real-world production environments. At its start in 2013, Docker was mainly used by developers as a sandbox for testing purposes. The change was happening, and it was happening fast more organizations were adopting containerized deployment methods (such as Docker) and DevOps practices and CI/CD pipelines to confidently deliver business-differentiating features quickly in an increasingly competitive market.

Kubernetes (aka K8s) is an open-source platform used to run and manage containerized applications and services on clusters of physical or virtual machines across on-premises, public, private, and hybrid clouds. In particular, achieving observability across all containers controlled by Kubernetes can be laborious for even the most experienced DevOps teams.īut what is Kubernetes exactly? Where does it come from? What problem is it trying to solve, and how does it work? What challenges does it present, and how can you overcome them? There’s no doubt it will be the orchestration platform of choice for many enterprises as they grow their apps over the coming years.Īlthough Kubernetes simplifies application development while increasing resource utilization, it is a complex system that presents its own challenges. Since Kubernetes emerged in 2014, it has become a popular solution for scaling, managing, and automating the deployments of containerized applications in distributed environments. With apps growing larger and more complex by the day, IT teams will require tools to help manage these deployments.

According to the 2020 Cloud Native Computing Foundation (CNCF) survey, 92% of organizations are using containers in production, and 83% of these use Kubernetes as their preferred container management solution. More applications now rely on containers and microservices than ever before. But these highly dynamic and distributed environments require a new approach to monitoring. Kubernetes is a popular solution for scaling, managing, and automating the deployments of containerized applications in distributed environments.
