What is Kubernetes?
In Kubernetes, containers are organized into pods, the smallest deployable units in the system. Pods can contain one or more containers and share network and storage resources. Kubernetes also provides features such as automatic load balancing, self-healing, and scaling, making it easier to manage containerized applications at scale.
Kubernetes is highly modular and extensible, with a large ecosystem of plugins and extensions that can be used to add additional functionality. It can run on various cloud providers and on-premises environments, making it a versatile platform for managing containerized workloads. Overall, Kubernetes has become the de facto standard for container orchestration and is widely used in production environments by organizations of all sizes. Its popularity is due to its powerful features, extensibility, and community support, making it an excellent choice for managing large-scale containerised applications.
Background of Kubernetes
Google originally developed Kubernetes as an internal project for managing their containerized workloads. The project was originally called "Borg" and was used by Google for over a decade to manage their massive-scale production workloads. In 2014, Google released the Kubernetes project as an open-source project under the Apache 2.0 license.
Since its release, Kubernetes has become one of the most popular open-source projects in the world, with a large and growing community of contributors and users. The project is now managed by the Cloud Native Computing Foundation (CNCF), a nonprofit organization that promotes using cloud-native technologies, including Kubernetes. Kubernetes has become the de facto standard for container orchestration and is widely used by organizations of all sizes to manage their containerized workloads. Its popularity is due to its powerful features, flexibility, and extensibility and the large and growing ecosystem of tools and plugins developed around it.
Overall, Kubernetes has significantly impacted the development and adoption of cloud-native technologies. It is likely to remain a key part of the infrastructure for many organizations in the years to come.
OpenShift vs Kubernetes
OpenShift and Kubernetes are related but distinct technologies with some key differences. OpenShift is a container application platform developed by Red Hat, while Kubernetes is an open-source container orchestration platform originally developed by Google. OpenShift is built on top of Kubernetes, so it includes all of the core features of Kubernetes, plus additional tools and features to make it easier to manage containerized workloads.
One of the main differences between OpenShift and Kubernetes is their focus. OpenShift is primarily designed to be a complete platform for building, deploying, and managing containerized applications. It includes various additional tools and features, such as an integrated development environment (IDE), a source code management system, and a continuous integration and delivery (CI/CD) pipeline. Kubernetes, on the other hand, is primarily focused on container orchestration and provides a powerful set of features for managing containerized workloads.
Another key difference between OpenShift and Kubernetes is their ease of use. OpenShift is designed to be more developer-friendly and easier to use than Kubernetes, with a user interface that makes it easier to manage applications and workloads. Kubernetes, on the other hand, is more complex and requires more technical expertise to manage effectively.
