Docker allows us to have a more agile and less expensive Life Cycle since it allows us to encapsulate a development environment with the same characteristics to a production environment and being identical is where the big problems of distribution and software delivery of a software are solved. around another.
Thanks to Docker we reduce the product delivery cycles and all this leads to what would be the cycle of Continuous Integration and Contiguous Delivery (CI / CD), with Docker we no longer have to create a time window on a specific day or date. make a product update, that is, what every IT or Development department wants …
Docker offers us one more level of isolation within virtualization, as it manages to isolate and package at the application and library level through the use of containers.
Docker is a fully scalable and elastic technology as more and more companies are having an unpredictable workload in IT services where capacity and performance are not predictable and it is here that Docker through the use of its containers makes the demand of resources is limited to the consumption of the application and all this in a fast way since starting a container are seconds.
A great question that people ask themselves when they start in Docker’s world is Containers or Virtual Machines? As I always say in my courses and clients are two different things, although we speak of Virtualization, the Virtual Machine is a complete operating system operating in isolation from another complete operating system and that allows us to share a Hardware so that they can use it several operating systems at the same time and a container is something totally different since a container instead of hosting a complete operating system what they do is share resources of the operating system on which they run and isolate the applications.
From my point of view, Docker offers us many advantages when it comes to distributing and executing software that translates into using fewer resources, making the life cycle more dynamic, all this means that we can save costs. In short, Docker makes us more competitive.
