The market is constantly evolving and companies need to stick to new technologies to stay competitive. It is a struggle to create quality products and services at a lower cost.
The microservices they are part of these new technologies. A survey by O'Reilly found that, in 2020, a 52% of organizations uses concepts, tools or methods of microservices for software development, which shows its current importance.
If you still don't know what it's about, find out what are microservices, its advantages and what is its relationship with cloud computing in this article.
What is cloud computing?
To understand what is cloud computingThink about the services and processes that you know hosted on the web and that work through the Internet. Basically, companies have the opportunity to hire cloud services to launch applications without the need for their own IT infrastructure.
Now, microservices are native to the cloud and are what allow the cloud computing software to be what it is today: an agile and easily scalable solution.
What are microservices?
Contrary to what you might believe, the term does not refer to the size of the services, but rather to the style of the system architecture.
The idea arises from the need to develop systems that are flexible, scalable and easy to maintain. In this way, the objective of microservices is to put aside monolithic applications (that is, where all functions are grouped in the same code) so that each microsystem works independently, but focused on a single function.
Thus, an application based on microservices consists of many components or small modules coupled together, but which are still free and independently deployable.
So, you ask yourself: if they are independent, how do they fit together? Easy, through a set of predefined commands, functions and protocols, better known as APIs, to establish communication.
Advantages of microservices
1. They offer stability
Since each service is autonomous, developers can maintain and update each feature independently without affecting the rest. You will only give growth to the functions you want.
On the other hand, if a microservice has problems, it will not affect the general operation of the application. For example, if the payment system fails in an online store, the user can continue browsing through the catalog and the rest of the website until the problem is resolved.
2. They provide flexibility in the application of technologies
One of the drawbacks with monolithic applications is that you have to work with the same technology throughout the entire application. Microservices change that, here developers can use the technologies that best suit each function.
Additionally, you can use specialized teams to work on the various components, which will ultimately increase the quality of the software.
3. They help reduce costs
Applications only use the microservices they need, therefore costs will only be associated with the functions and use of the system. Thus, costs associated with unused functions do not have to be considered. In addition, maintaining each microservice part separately results in cost optimization by not having to review the entire architecture, for example, in case of diagnosis bugs in one of them.
4. Contribute to scalability
Being autonomous and being able to work independently, the microservices are easily scalable, facilitating the development of one over another according to the temporary strategies of the business, thus helping to generate scalability throughout the company.
In conclusion, microservices are part of the wonderful advantages of cloud computing, a technology that is becoming more and more important in the digital world.
