The word Kubernetes is probably unknown to a lot of people and this term is so strange that you cannot associate it with anything else. Well, what you probably don’t know is that it has experienced exponential growth lately.
And this shouldn’t come as a surprise, since it does come with a variety of different advantages. You may be confused by this conclusion because you’ve never heard of Kubernetes before, however, those who are familiar with the IT sector, already know how essential it is.
Without further ado (because we do not want to further cause any confusion), this guide is about to uncover various, interesting facts about Kubernetes, that just might stimulate you to dig deeper as far as this is concerned.
Let’s Define It First!
Kubernetes can be defined as an open-source platform that’s intended for containerization applications. It got its name from the Greek word, which represents a pilot and helmsman. The main goal of Kubernetes is to lead application development in a relatively simplified fashion, eliminating anything that’s considered redundant.
At the heart of this platform lies the container. In conventional software development you must make use of numerous libraries which are situated in the software, and, at times, they “inhabit” the computer itself.
The main goal of the container is to get rid of all the irrelevant parts of the application and leave only the important elements of the operating system. To put it simply, Kubernetes can be perceived as the system that allows developers to run more than one container simultaneously, under the same management.
Reasons Your Company Should Employ Kubernetes
Those who’ve utilized Kubernetes in the past, know how beneficial it is. If you would like to make the most out of it, then it would be advisable to resort to Kubernetes expert hire, because these professionals know how to implement it properly. Speaking of it, the perks of leveraging it include the following:
- Reliability – It is an excellent way to make containerized applications a lot more effective and reliable. It can instantly scale up a pod of containers as soon as the traffic is boosted. Furthermore, it supervises nodes and containers, offering self-healing properties. In addition, Kubernetes enables you to effectively allocate workloads in a Kubernetes cluster, ensuring much higher availability.
- Portability – In comparison to the virtual machines, the features of containers are a lot more lightweight and flexible. With containers, you are capable of running several applications simultaneously, on one server utilizing fewer resources. In a nutshell, Kubernetes is extremely agile due to the fact that it’s compatible with practically any container.
- Simple cloud migration – Your company can begin building containerized apps employing the infrastructure on-premises, however, with Kubernetes moving to the cloud is much simpler and faster. With it, you can either select one cloud for the container, or you can spread them across multiple cloud providers, such as Amazon Web Services, Google Cloud Platform, Microsoft Azure, etc.
- Kubernetes is very safe – It’s worth mentioning that Kubernetes provides configuration management features that are extremely efficient, taking security to the next level. You can safely leverage and store sensitive data, like OAuth tokens, SSH keys, and passwords.
What Needs To Be Said About Its Architecture?
Its architecture is modular and allocated, which means that you can easily manage containerized applications across different machines. A Kubernetes cluster consists of a single Master node and a couple of worker nodes, and every single one of them plays an integral role in handling applications. Kubernetes deployment utilizes these components:
- Clusters – Clusters contain nodes, and every cluster consists of several worker nodes that run, deploy, and manage containers, along with the Control Plane node that supervises and manages the worker nodes.
- Pods – These represent a group of containers that share a network and compute resources. If any additional capacity is required to deliver an application running in containers, then the software is able to effectively replicate the entire Pod to boost the capacity.
- Nodes – It’s one compute host that can be a virtual, physical, and/or cloud instance. Nodes can be found in a cluster of nodes. Worker nodes can host the deployed containers, while the Control Plane node manages the worker nodes. Every worker node runs an agent that’s known as a kubelet that the Control Plane node employs to manage and supervise it.
- Deployments – The deployment showcases how many replicas of a Pod are supposed to run on a cluster. If by any chance, a Pod experiences any failure, the deployment will recreate it.
If you work in the IT industry, yet you weren’t too familiar (or at all) with Kubernetes, we truly hope that this informative guide has made things clearer and that you will finally start reaping benefits from it.
