Microservices<\/a>, also known as microservices architecture, is a style of software architecture that structures one or more applications with a collection of highly flexible and maintainable services.<\/p>\n\n\n\n

According to IDC<\/a> The forecast is that by 2022 90% of all new applications will have microservices architectures, improving the ability to design, debug, update and leverage third-party code, in addition to 35% of applications will already be developed in the Cloud.<\/p>\n\n\n\n

Therefore, microservices architecture allows an organization to develop its technology stack with fast, frequent and reliable deliveries, whether large and complex applications or less robust demands.<\/p>\n\n\n\n

To implement microservices, the infrastructure must be fully focused on the work model, through a\u00a0DevOp culture<\/a>s<\/a>\u00a0well-structured and with an Agile mindset, for example. Furthermore, it is necessary to have specialized help and carry out a segmented but continuous migration.<\/p>\n\n\n\n

In this article you will see the advantages of microservices for software and application development projects, what obstacles may arise in this process and how to effectively carry out this migration. Let's go?<\/p>\n\n\n\n

Why consider the microservices model for your next application development project?<\/h3>\n\n\n\n

With microservices, your entire application is decentralized and decoupled into small services, i.e., one-off deliveries that work separately. See the reasons why you should opt for this methodology.<\/p>\n\n\n\n

Resilience<\/h5>\n\n\n\n

Unlike the monolithic architecture, in which a failure in the code affects more than one service or function, there is a minimal impact of a failure when microservices are applied, that is, the infrastructure is completely resilient even when several systems are shut down for maintenance.<\/p>\n\n\n\n

Scalability<\/h5>\n\n\n\n

Scalability is the key aspect of microservices. Because each service is an individual component, you can scale a single function or service without having to change the entire application.<\/p>\n\n\n\n

Availability<\/h5>\n\n\n\n

By replicating essential services across multiple servers, it is also possible to increase the availability and performance of the system without affecting the performance of other services that make up the infrastructure.<\/p>\n\n\n\n

Productivity<\/h5>\n\n\n\n

In microservices, each service can use its own language, framework, or helper resources while still being able to communicate easily with other services. Furthermore, the model eliminates the need to rewrite the entire code base to add or modify a feature and smaller increments can be tested individually, which increases the productivity and efficiency of projects.<\/p>\n\n\n\n

Continuous integration and delivery<\/h5>\n\n\n\n

Continuous integration and delivery are key concepts of the DevOps philosophy and Agile mindset. Microservices architecture enables cross-functional teams to independently develop, test, troubleshoot, deploy, and update services.<\/p>\n\n\n\n

Flexibility<\/h5>\n\n\n\n

Each service can be developed, deployed, and managed independently and can utilize different programming languages, technologies, and programming environments based on individual needs.<\/p>\n\n\n\n

Ease of debugging, updating and maintaining<\/h5>\n\n\n\n

Microservices also make debugging and testing applications easier. With smaller modules, continuous deliveries, and testing, the ability to deliver error-free applications is vastly improved.<\/p>\n\n\n\n

What obstacles may arise in the process?<\/h4>\n\n\n\n

Some obstacles may arise in the process of migrating to microservices and must be overcome to be successful with the infrastructure based on this working model. See what they are below.<\/p>\n\n\n\n

The project must fit with the microservices model<\/h4>\n\n\n\n

Microservices are not suitable for any project. Companies that adopt this methodology see significant gains, however, although it is highly promising, not all infrastructure is capable of capitalizing on the architecture and ensuring that their teams are truly prepared for the continuous deliveries and testing culture required in this work model.<\/p>\n\n\n\n

The company must have a DevOps culture<\/h4>\n\n\n\n

Microservices requires the incorporation of good practices and the dissemination of a development culture within the company's humanware. This is because, in multifunctional teams, everyone must be responsible for provisioning the service, that is, for the gains and failures that may eventually occur.<\/p>\n\n\n\n

The test is not simple<\/h4>\n\n\n\n

With microservices, testing is not simple. Each service has its own dependencies, some direct, some not. As resources are added, new demands appear and you must maintain control and\u00a0monitoring\u00a0<\/a>over all processes, mainly because the complexity of the result increases according to the number of services added.<\/p>\n\n\n\n

Therefore, it is necessary to know how to deal with a reasonable level of failures: whether in the database, network latency or service unavailability, which requires the constant application of resilience tests, fault injection and load balancing.<\/p>\n\n\n\n

Requires team preparation<\/h4>\n\n\n\n

As we said, applying the microservices model requires preparation from the team, both to provide high availability with deliveries and to deal with the various possible failure problems:<\/p>\n\n\n\n
