The problem of an application or software failing to run properly when moved to another environment is as old as software development itself. For example, the new environment is set up slightly differently than the environment in which the software was created. That is why software development technologies are also increasingly adopting a method that uses containers.
A container is a standard software package that contains an application's code as well as the associated configuration files, libraries, and dependencies required to run the app. In this way, developers and IT professionals can seamlessly deploy applications in different environments.
The container concept enables developers to build environments using functional blocks with each just one task. The idea is to divide an application into components, each of which has a single function or active process. A WordPress application, for example, is made up of three parts: a web server, a PHP engine, and a database server. Each of these functions will be carried out in its own container. In this method, each function is completely isolated from the others, and many containers can coexist on a single OS instance (e.g., a VM), just like on a container ship.
However, containers are not flawless and have their disadvantages and limitations as well. To begin, developing, launching, and effectively managing a container strategy necessitates a surprisingly large amount of setup work. There is insufficient app support and dependency, and despite emerging technologies, there is currently no complete solution. Additionally, in many cases there are not enough qualified, skilled and experienced experts in the field.
VPSs and containerization are similar in some ways. For example, they both allow for full isolation of applications so that they can be operational in multiple environments. Where the main differences lie are in size and portability.
Typically, a VPS is bigger than a container and on top of that, it has its own OS, which allows it to perform multiple resource-intensive functions at once. Containers are smaller and work well with newer and emerging technologies like clouds, CI/CD, and DevOps.
