What is Kubernetes?
Kubernetes is an open-source system for managing containerized applications in a clustered environment – perfect for DevOps teams who need to deploy and scale apps quickly and reliably. If you’re not already familiar with containers and containerization, it might be helpful to read up on that before diving into Kubernetes; but essentially, containers are a way to package an application so that it can run isolated from other applications on a shared operating system. Containerization has become very popular in recent years as a way to build and deploy scalable applications quickly and reliably..

Kubernetes is a system for managing containerized applications in a clustered environment. It works with a range of container tools, including Docker, rkt, and lxcfs. Kubernetes is designed to automate the deployment, scaling, and operations of application containers across a cluster of servers.

Kubernetes was originally developed by Google, and is now maintained by the Cloud Native Computing Foundation. It’s worth noting that while Kubernetes borrows some concepts from Google’s Borg system, it’s not Borg – Kubernetes is very much its own thing. (And it’s also not a Google product, despite what some people might think!)

If you’re not already familiar with containers and containerization, it might be helpful to read up on that before diving into Kubernetes. But essentially, containers are a way to package an application so that it can run isolated from other applications on a shared operating system – sort of like virtual machines, but much lighter-weight and with a lot less overhead. Containerization has become very popular in recent years as a way to build and deploy scalable applications quickly and reliably.

How Does Kubernetes Work?
Now that we’ve answered the question “what is Kubernetes,” let’s take a look at how it actually works.
As we mentioned earlier, one of the key benefits of Kubernetes is that it automates the deployment and scaling of containerized applications. You can use Kubernetes to define how your applications should be deployed and scaled across a cluster of servers. Once you’ve done that, Kubernetes will take care of everything else – making sure that your applications are always running as you expect them to, and scaling them up or down automatically as needed in response to changes in load or traffic patterns.

In addition to simplifying deployments and scalability, Kubernetes can also help you manage your application’s availability and handle failovers automatically. For example, if one of your app’s nodes dies or becomes unresponsive for any reason, Kubernetes will detect the problem and spin up a new node to take its place. This ensures that your application remains available even in the face of hardware failures or other problems.
Kubernetes also makes it easy to roll out updates to your applications – whether you’re upgrading to a new version of your software or simply making changes to your app’s configuration. With Kubernetes, you can push out these updates gradually, letting you test them thoroughly before rolling them out to your entire user base all at once. You can also rolled back easily if necessary.

All of these features combine to make Kubernetes an invaluable tool for anyone who needs to manage containerized applications at scale – which is why it’s become so popular in recent years!
