One of the positions that in 2020 we have seen growing up in IT searches are the Devops professionals, and in the search for these profiles we find that the microservices implemented through the use of containers are increasingly used by our client companies.
In today's article, we bring you a little more information about it.
The conversation around using Kubernetes or Docker is usually limited to the following: Do I use Docker or Kubernetes? Here is the biggest common mistake, thinking that you have to choose between one or the other.
First of all, we need to understand what software containers are.
A container is a closed package that contains everything necessary for an application or a service to run encapsulated within a single image completely independent of the host server that hosts it.
The idea behind this is that it is light and portable, that it can be transferred between different environments without setbacks since the internal workings are completely independent of the operating system that hosts it.
And what are the advantages?
It can be easily versioned, reused and replicated by other developers or by system administrators who have to scale those applications without having to know internally how our application works.
So what are Kubernetes and Docker?
Docker is a system that allows us to build, transfer, deploy and run the containers with our applications within a very simple and reliable way, guaranteeing an efficient scalable deployment regardless of the host operating system.
Kubernetes is a system that is responsible for distributing the containers throughout the system according to the resources available in the cluster, as well as creating, running, monitoring, measuring, destroying and relaunching the containers.
