Advantages of using microservices against traditional web services:

Every day more projects in the application development world choose to develop their web services using microservices architecture instead of traditional architecture due to several advantages they possess. Within them, it is found that when using microservice architecture, you can modularize and decouple each of the methods that could offer an API for some application. Getting to have different groups of dedicated software development teams and even developing in different languages (the one that best suits) in the method that needs to be developed and work with one different database engine on each service(relational like MySQL, Oracle, etc) as nonrelational like MongoDB.

A clear advantage over traditional services is that at the time of an upgrade, maintenance or if any failure occurs this does not compromise the complete stability of the application. As it would only affect the module in which the web service participates, so it is much easier to maintain or update, this is achieved because each microservice has its container where they are exposed achieving a complete separation between all the services that form part of the API in contrast to the traditional architecture.

Another advantage is that you can scale on a software level more easily than with a traditional process. instead of replicating all the application you can replicate only the service with more load. You have separate in minor modules the business logic. being much more readable on large scale projects. The microservice architecture is designed to tolerate faults. Following configuration patterns so that the response time to a possible fault can be as short as possible, this represents a clear advantage in large projects. You can have collaborative modules between different companies participating in large scale projects. Making it an easier integration between both parts. Significantly reducing development time.
