Microservices

This article deals with the subject Microservice, which is to separate a program into small services where each of them running in their own process, I remembered the motto of a sorting algorithm "Divide and conquer" whose objective was the same. The purpose of this style is facilitate the updating and modification of our program. It is mentioned that in a monolithic programming style, you can't change a single module, needs to be updated whole the application or program every time a change is made.

On the other hand in a style based on Microservice we have the advantage that if we modify some modules of the application, we can go only to the module or service that will be updated and this is enough for the changes to be reflected the whole application.

Another advantage of this technique is that by putting each element as a separate service, in the situation where a replication of data related to the information stored in the database is required, only the data replication that is required are performed and not all the information as would be done in any other style. This allows to carry out this task effectively and without wasting resources.

Componentization (term ascribed to the action separating an application into services) has as main advantages:

•  Allows services are independently deployable, so modification is simple and effective.
• Minimize cohesion, which refers to the relationship maintained with other services and that both affect the changes made in one service to another service.

The industry related with information technology (IT) chooses to organize services depending on your skills or capabilities, this allows a group to be able to develop and operate the same product, and not as has been done in recent years, that people who develop applications are not responsible for the maintenance of it.
