While talking about cloud computing and containers, the issue of Kubernetes vs. Docker is often posed. This isn't really a valid question, however. Don't screw with Kubernetes and Docker. These are basically different technologies that work well together to create, execute and scal containerized applications.
An important part of DevOps ' development is to consider how Kubernetes and Docker containerization blends with the app and web network.
What's a Container & what good is it for?
If mobile app developers need to use a new app on a new computer, certain steps have to be taken first. Perhaps even updating the operating system.
What if there were a single package that had all you needed? Each specification, application, frameworks or even security configuration is bundled into a good, clever, all-inclusive package. You just have to download it and used it.
Containerized systems have a single file, which is called an image, which includes all the dependencies, settings and frameworks. The most important advantage of a container is portability — it can be run wherever you need it. You 're on the desktop. You 're on your local server. It's in the cloud. It will always work the same way, regardless of capital. Containers separate information from their environment and ensure that it works continuously.
Unlike freight shipping containers with a standard size for storage and portability, software containers use a specific interoperability and portability model.
The downside is that tanks have a very small footprint. You only need a request and a description of all the libraries available. Containers share the kernel of the Host OS to virtualize the programme, unlike virtual machines which each need a complete copy of a guest operating system.
Should I use a Container?
If you use an infrastructure for a microservice or want to turn into such an architecture, Kubernetes will be right for you. It is particularly good to use containerization software like Docker now. Many organizations thus rush to use Kubernetes without understanding the fundamental concepts of the distributed system. We seek to set up their own cluster of Kubernetes and host simple websites or a small flexible framework. This is risky — because things will break down easily because you do not have a deep knowledge of the system.
Container technology is here to work like Docker and Kubernetes. They help us to focus on systems and applications in a new way and are fundamental to our DevOps engineering services. All systems complement one another and are constantly evolving.
The architecture of container-centered platform software makes the applications more scalable and future - proof. Old VMs could work Well for now. Nonetheless, you want to move to a containerized platform in a few years' time.
