Everything You Need to Know about Kubernetes Administration
The media was already showing it as fiction when Google CEO Eric Schmidt formally recognized the concept of “cloud computing”. The phenomenon has become widely popular ever since. The power of seamless connectivity across borders only requiring internet connectivity has become a norm these days, especially for businesses that often engage in cross-border trade.
As with all other IT solutions, once it was introduced, the IT community joined heads to decide how to improve the efficiency and reliability of this mechanism. As companies began entrusting “clouds” with sensitive business and client information, efficiency concerns became higher, which eventually led to the idea of application containerization, also known as Kubernetes administration.
What is Kubernetes?
As they (kubernetes.io) themselves put it, “Kubernetes is a portable, extensible open-source platform for managing containerized workloads and services that facilitates both declarative configuration and automation.” It is also known as K8 and originates from the Greek language, literally translating as “pilot”. Google had already turned Kubernetes into an open source platform in 2014. Naturally, following this period, Kubernetes practices became widespread, its support and tools available freely and easily.
Kubernetes is a kind of a cross between Platform as a Service (PaaS) and Infrastructure as a Service (IaaS), offering the best of both worlds bundled into one. Most rampantly, Kubernetes is used to regulate cloud-native applications so that these can operate anywhere and everywhere, at the complete discretion of the user.
Benefits of Kubernetes Administration
Most modern software utilizes cloud computing technology in some way or the other. The flexibility offered by cloud-native applications is second to none, allowing users to control both experiences and access to the applications as required.
The Hot and Happening
Kubernetes is being used far and wide. When developers write applications, Kubernetes is not only ensuring they work seamlessly in all environments but also ensures containerization without restrictions. This does not only mean the applications are not tied to a particular framework but also that these can be moved between the physical and virtual implementations without problems. And while you’re at it, rest assured given the popularity of Kubernetes administration, there are ample support and tools available to achieve a multitude of tasks. Specialists who carry the Kubernetes Administration Certification are, particularly in high demand.
Modular Containerization Management
It is one challenge to be responsible for an entire project, and a whole different story to be responsible for a small, manageable portion of it. Kubernetes offers the flexibility of breaking down applications into distinct smaller parts, each put into its own container with visible boundaries. This allows greater flexibility and control for the development teams, each being held responsible for their own. As a result, development is faster and well-tuned. Furthermore, the containers are programmed to work together as an application. These can share resources and be collocated, so the developers do not feel the need to cram too much into one. Kubernetes is all about creating a system of functional containerized programs that are easy to manage and develop.
Automation, Deployment, and Scaling
Kubernetes offers the flexibility and infrastructure to monitor the progression through the application lifecycle. It needs the Kubernetes Controller which helps in performing several complex tasks.
- The application can be scaled in or out at will.
- It offers greater visibility for in-progress, completed, and failing deployments, with varying query capabilities.
- Progress can be halted and restarted to benefit from time savings.
- Offer seamless version control, allowing the developers to roll back to a previous release as and when required.
Kubernetes is not limited by application frameworks, programming languages, or the 12-factor applications. It often doesn’t distinguish between “apps” and “services”, offering increased flexibility across all dimensions. Kubernetes is popular for its innovation, architecture, and the presence of a huge open source community of like-minded experts.
Getting Certified
As with all good things in the world of Information Technology, it is possible to become a certified Kubernetes Administrator, a feat which will not only enhance your value in front of prospective employers but also help you be seen as an authority on the subject, so you are given complete control. There are multiple courses available for Kubernetes certification. However, to be eligible to pursue any of these, it is important for the candidate to be proficient with the Linux CLI/Linux Fundamentals. Knowledge of Enterprise Linux Systems Administrator is preferred though not mandatory. Likewise, the applicant should have some basic knowledge about containerization or Dockers.
Depending on the course chosen, the application will be put through three or four days of theoretical and lab training. There are quite a few online courses available to help these individuals prepare for the Kubernetes Administration Certification. At the end of the course and certification, IT practitioners will not only be able to understand the concepts of Kubernetes but also be able to implement these in the working cloud environments.
Conclusion: Who Can Benefit?
The Kubernetes Administration certification does not only benefit IT practitioners by getting them at par with the best industry practices but also helps startups and well-established enterprises benefit from the flexibilities offered by it. It is easy to deploy, works across traditional boundaries, and aids the development process in numerous ways. So, whether you’re a business looking to train IT professionals or an individual hoping to succeed in their field of work, the Kubernetes Administration Certification is definitely something to try. Get enrolled in the preparatory courses today. Take Kubernetes certification training and practice examination session to get a realistic idea of the real test.
