What is Docker and Kubernetes?

Know Everything About Kubernetes and Docker.

Everyone across the is affected by the ever-changing course of the world of the technological sector. Technology is an irreplaceable and a non-negotiable part of human existence. The technological advancements that are happening across the globe have affected each and everyone of us. No matter whether you are a fan of the newer technology or not, you cannot run away from it.

Since we have already established the part which states that technology is always changing and becoming better, keeping updated is what one should always aim for. Being updated with the advancements will always come in handy when you set out to revert to what is best for you as an individual or for your business.

Docker and Kubernetes are counted amongst the top on the list of the most persuasive and dominant open source projects of the year 2018. Whether you are a professional in the IT sector who is looing to broaden their job prospects by taking by newer and influential certifications or you are a beginner who is searching for certifications that are impactful or you are simply someone who likes to be in touch with the major progressions in the field of tech, this blog will aid you in sorting out what is Docker and Kubernetes.

How is Docker and Kubernetes Connected?

While there certainly is a connection between Docker and Kubernetes, it is totally uncalled for when people go about and try to find a comparison between the two. It is like comparing a tomato to a potato.

But talking about the connection, it lies in the fact that while docker can run without Kubernetes and vice versa, they work together beautifully as well. When it comes to complimenting one another, Docker and Kubernetes do it well.

If you need to containerize applications, then you can simply install Docker on your computer to do so. Are you aware with what exactly containerization is? Well, to containerize is to make sure that separate running applications on an Operating System are kept running smoothly, irrespective of what happens to the rest of the system. Thus, with Docker, you can run, manage, and create multiple containers on one OS.

However, as said above, the two work wonderfully together. If you add Kubernetes to the entire equation, then the impact or the outcome increases manifold. With Kubernetes installed on the operating system, you can automate, networking, security, scaling, container provisioning, and load-balancing across all Docker hosts and that too from only one dashboard or command line.

Only one individual Kubernetes instance is required to manage the entire collection or host of these nodes. It is known as Kubernetes Cluster.

Now that we know the point of connection between Docker and Kubernetes, let us take up what they individually are.

What is Docker?

Docker is both a platform for software packaging and delivery as well as a container which is a lightweight virtual machine. Over the years, Docker containers have been of great importance. People in the IT industry have benefitted substantially from these containers. The business world has always taken a greater leap because of them.

Developers seriously seem to benefitted from Docker because over the years, they have always seemed to have been affected by variances among production server.

What is Kubernetes?

As stated above, while Docker is the technology related with containerization, Kubernetes is the technology that takes this same containerization technology and turns it into something a lot of greater and beneficial. Kubernetes gives us the opportunity to make these containers work across several compute nodes or Docker hosts.

Conclusion

If only the technology world was as simple as to be describable in a few words or sentences, not so few people would have been a part of it. the above blog is written with the purpose of giving you a glimpse into what is Docker and Kubernetes but as said above, it is not possible for one to know everything there is to know with just words or theoretically.
