Cloudways offers managed cloud hosting for any size business to host a website or complex web applications.

The open-source platform called Kubernetes (also abbreviated as K8s) enables the deployment, scaling, and management of containerized applications regardless of location.

It was initially created at Google and released as open-source in 2014 before being donated to a foundation for cloud-native computing (cncf).

Kubernetes might be your answer if you’ve been seeking a strategy to grow your applications, deploy code more quickly, and reduce costs. This technology has completely changed how programmers create and maintain programs.

A global network of skilled programmers and coders supports the platform. The largest enterprises in the world deploy and scale applications using its container orchestration technology. Companies like Google, Twitter, Facebook, and Uber have all utilized it to create successful applications with millions of users.

Additionally, businesses like Oracle, Box, and Twilio use it as their main container platform. Kubernetes has transformed over the past few years from a minor side project to an essential component of the modern software development and IT operations landscape.

The million insights research, which indicates that the worldwide application container market size is predicted to reach USD 8.2 Billion by 2025, can be used to analyze the expansion of containerized applications.

Why is Kubernetes use expanding so quickly?

The ability to manage your apps and containers across many cloud providers, such as Amazon Web Services, Google Cloud Platform, Microsoft Azure, and IBM Bluemix, is one of the main arguments for using Kubernetes. This enables you to keep a single, consistent application architecture while scaling your application horizontally across multiple providers.

This, in turn, helps to scale your application in a faster space and save time and money by reducing the need to move your infrastructure between providers.

How do Kubernetes work?

  • It offers a standard API that programmers may utilize to deploy apps everywhere.
  • You can use the capabilities of a PaaS (platform as a service) with Kubernetes to deploy apps more quickly and with less effort.
  • Applications can be deployed and controlled dynamically and are divided into smaller, independent parts.

How important is Kubernetes in today’s Cloud Computing landscape?

Kubernetes is an orchestration service used in today’s Cloud Computing (CC) landscape to manage containerized applications in distributed computing settings. An intriguing alternative to the conventional monolithic way of delivering apps is using a container orchestrator like Kubernetes, especially in terms of scalability.

By offering a highly scalable (hundreds of thousands of containers are formed at any given moment) and secure platform on which to host containers and deploy and run applications, Kubernetes makes the process of deploying, scaling, and maintaining containerized applications simpler.

According to a report by Gartner, global container management revenue will increase significantly from a low base of $465.8 million in 2020 to reach $944 million in 2024, and a significant portion of this growth comes from public cloud container orchestration and serverless container offerings.

Below are more reasons why Kubernetes is widely adopted in cloud architecture:

  • Creating container images is quicker and more efficient than utilizing VM images when delivering agile apps.
  • High Availability: This is very helpful for applications like database services and web servers that need high availability.
  • Creates application container images at build/release time rather than deployment time, which aids in decoupling applications.

Let’s see how IT professionals can become part of this growing, high-demand Kubernetes technology.

What does a Kubernetes certification certify?

Any certification program aims to show that a candidate has the skills and knowledge required to carry out specific activities in a career or role. The most well-known way to do this is to take a number of exams, most of which are written and tested. Certification for Kubernetes is no different.

A Kubernetes certification is a demanding technical curriculum that evaluates candidates’ expertise on a selection of fundamental subjects. It is demanding since passing it is challenging and requires much effort. The exam measures your understanding of key Kubernetes concepts like deployments, stateful sets, pods, services, replication controllers, etc.
