Hi,

Let me explain to you with the containerization and see what problems are solved with this technology?

Major challenges that organizations facing which containerization solved

This article summarizes one important insight: most software is containerized.

If this seems complicated, I would also suggest reading about What is containerization in general?

Software containers are defined by the following two concepts:

Containerization is the process of bringing together several different systems or applications into a single, highly configurable system that runs in a similar fashion all the time.

This describes the best way of combining different system components into a larger and more flexible system.

Containerization is the concept of dividing (or isolating) software components into smaller, more reusable components and therefore making them run together more often.

And as we can notice, the use of the word 'containerized' in containers focuses on containerization as a configuration management strategy, whereas in software containers refer to the process of making the whole software configuration management infrastructure containerized.

In general, the more complex the configuration management infrastructure is, the bigger the risk is that the whole software needs to be containerized - even though configuration management is just a part of the overall software functionality, since it handles the administration of each software component.

Here are some of the major challenges that organizations can face while trying to achieve containerized configuration management:

A software application needs to be configured in a large number of different instances and there is a huge effort involved in creating the configuration. At that level, it is very hard to make use of the existing infrastructure to bring all the instances to run together.

The configuration of the software has to be stored in a central database and then moved from different clusters for each application that runs in the service. This process is very complex and most organizations can't easily perform this work on their own.

A system has to have an extremely high number of configuration management jobs running for each instance of the system that can handle different configurations.

The configuration management infrastructure has to be integrated with other services to offer the best possible configuration management for the entire system and its services.

The use of configuration management for software is often described as a series of actions that are performed one to another. This description ignores the fact that each of these steps is actually a configuration step; all these steps have to be performed before, during or after any configuration steps.

The use of application containers to manage software is typically described by adding layers atop any specific software component and it is in fact a very straightforward way to achieve the desired configuration management in a software application.

As a matter of fact, many of the organizations who deploy application containers today are doing this, because the containerization technology was initially developed to manage the entire system with one central configuration management infrastructure.

The real benefits for organizations to manage both software and configuration in software containers

If you need to combine both the configuration management of the software and the configuration management of the configuration management infrastructure, I would suggest that you will benefit from using application containers, even though the two concepts are usually considered as separate concepts nowadays.

Here are some important benefits that application containers apply to an organization:

It can easily manage the complex infrastructure that it will need to build in the future which will be needed to enable container-based software to run.

The software can be configured in many different ways in a software container. Since the application container is a configuration management infrastructure that performs many different tasks before it finishes running, a significant part of the configuration management infrastructure has to be removed from the software container ? even though at a higher level the software still has its configuration management.

Containerization has more flexibility in that the software components can run in multiple different environments at the same time as compared to a software container that is designed as a specific environment for a specific software component.

However, not all organizations have the tools to work with application container technology, even though it can certainly be a powerful tool.
