Nowadays, more and more complex applications are created. They usually contain many containers across multiple hosts, which makes it quite difficult to control them. The best solution to this problem provides a special platform intended to orchestrate, control, and automate all the components. Find out what Kubernetes is, how does it work and why you should use it.
What is Kubernetes?
Kubernetes (κυβερνήτης, gr. helmsman, captain, pilot, governor), also known as K8s or K-eights, is an open-source system for automating software deployment, scaling, and management. Platform groups containers that make up an application into units, which makes control and discovery much easier.
The project was created in 2014 on the initiative of Google employees but currently is being developed by the Cloud Native Computing Foundation. The platform is commonly used by e.g. Amazon, Google, IBM, Microsoft, Oracle, Red Hat, and VMware. These companies offer Kubernetes-based platforms or infrastructure as services that deploy Kubernetes.
How does Kubernetes work?
Kubernetes works with various container tools, incl. Docker. What is more, the platform provides its own set of tools to deploy, maintain, and scale applications based on CPU, memory, or other custom parameters.
Kubernetes has an API interface that allows to fully manage containers and applications, influencing when, how, and where they will run. It controls computational and memory resources, treating them as objects. On their basis, it plans the operation of containers, which are grouped into clusters (the base operating unit of the platform), which can be easily scaled to the appropriate state. At the same time, the platform constantly runs health checks and allows applications to self-heal by replicating containers or restarting them.
The Kubernetes platform can also automate the discovery of services, track resource allocation, balance the load or scale based on the use of computing resources.
The Kubernetes platform is great for hosting cloud-native applications that require rapid scaling. It is compatible with most public clouds and services provided in the PaaS and IaaS models, so it is perfect for Big Data.

Why should you use Kubernetes?
Containerized applications are difficult to maintain as they tend to be deployed on different machines. Thanks to the Kubernetes platform, it is much easier to manage them, plan their operation, scale them, etc. Its environment allows to automate many processes and is extremely friendly to programmers. Not only is it conducive to the proper operation of the application, but also helps to develop and expand it.
The Kubernetes platform is a very cost-effective solution. If you use the support of a cloud provider such as CloudFerro, you only pay for the actual underlying infrastructure, computing power, and storage.
