The future of IT architectures? Microservices are gaining ground in the business as a key innovation in software development. As such, they are consolidating as an essential element for a company's digital transformation. Some of the attributes which have already been profusely incorporated by developers include improvements in the time frames, performance and stability of a project.

But what exactly are microservices?

The term "microservices" refers to an organization and architectural style in software development made up of small independent services working together to perform the same tasks. This approach to software programming has a direct and immediate impact on business, as applications are faster to develop and easier to scale.

 

Unlike traditional and monolithic application structures, where all processes are connected and run as a single piece, a microservice structure works as a correlation of small services that run independently and autonomously. That way, each one of them can be modified or updated without affecting the remaining components in the structure. Not only that, but these services can also be written using different programming languages.

 

Specialized and autonomous: the two main features of microservices. Autonomy derives from the fact that each service can be developed, deployed, operated and scaled without altering the performance of the other components. The specialization attribute has to do with each module being focused on solving a specific problem within the structure.

Which are the benefits of using a microservice structure?

Work Team Performance

Microservices promote a better organization of work teams, as these can be managed and coordinated independently. When this type of structure is applied to the development process, each small, distinct team within an organization becomes in charge of one specific service and manages it individually, making it possible to choose the best tool for each job. The outcome will be noticeable in two aspects: decreased development time and increased organizational performance.

Scalability

This architecture enables each service to be scaled independently based on the application's demand. As a result, resource availability can be optimized more efficiently.

Versatility

Since it is possible to use different programming languages and technologies, each functionality can be adapted to the most adequate and profitable technology. Moreover, considering that microservices enable integration and continuous delivery, testing new ideas and switching processes back are made easier should something not work properly.

Reusable Code

Using microservices favors taking full advantage of any functionalities already developed by third parties. Concretely, the developer does not need to write from square one—instead, an already existing service can be used as a means to carry out a certain function and as a component for another.

Resistance

In a monolithic structure, an error in a single component causes a complete application failure. The microservices' independent function prevents this overall collapse since the development degrades the functionality causing problems without blocking the application completely.

Maintenance

It is simple and inexpensive. As any improvements can be made on a single module without the need to intervene in the whole structure, there is a significant reduction in both the process and the cost of maintenance.

 

Of course, the evolution of microservices faces some challenges ahead. Today, they have high memory usage, require experienced developers to operate them, can be heavy on the initial investment (both in terms of time and money) and are complex to manage in great amounts. But, undoubtedly, their benefits transcend these challenges. Microservices have already been adopted by companies such as Amazon, Netflix and Twitter.
