What is Docker?
Docker is the most comprehensive software container management platform. A container offers a comprehensive environment for proper operation of any system. It contains:
- system libraries,
- system tools,
They are congruent to a particular operating system image. This is how Docker guarantees that a system will be operating exactly the same within any container instance.
What does Docker offer?
containers share the same machine operating system core on which they have been launched. They use less RAM and they launch basically instantly.
Docker containers are based on open-source standards, owing to which it is possible to launch them on any main distribution of Linux, Microsoft Windows or Unix Like Systems (e.g. OS X).
the containers isolate applications from one another and from the basic infrastructure, while at the same time providing an additional level of application protection.
Not only will Docker find its way to production and stage environments, but it will also be used in local developer environments, which cooperate on complex and comprehensive IT systems. Containers enable developers to launch systems comprising an infinite number of subsystems on their local machine. This will simplify work related to developing any application.
Docker v. virtual machine
In terms of its capabilities, Docker undoubtedly outpaces virtual machines, which, to date, have enabled building portable IT system environments. Comparing virtual machines to Docker, it may be concluded that the former comprise an application, its required libraries, tools and entire operating system, which is why the entire environments take up gigabytes of memory space. Docker containers only store the application and its dependencies, but they share the core with other containers, operating as isolated processes within the machine on which they have been launched. Thus, what is saved is RAM memory, CPU time, disc space, and host operating system stability is not lost.
The lightness Docker offers makes it possible to be easily used to build advanced Continuous Integration (CI) environments.
Docker in the cloud.
BlueSoft has been working on Docker IT systems development for many years. We have managed to convince many clients to implement Docker in their infrastructures. We have noticed that Docker may be easily installed in cloud environments, e.g. AWS, which, when combined with a CI mechanism, leads to building a highly efficient process of implementing consecutive system versions, while retaining the possibility to modify practically any moment of the deployment process.
BlueSoft has successfully implemented many projects in this area. We will happily present our portfolio directly as well as answer more questions about technology itself and benefits to be brought by its implementation.
