Microservices Make This Decacorn Grow Big and Bigger!

Microservices are what made applications like Gojek, Grab, and Netflix become big as they are now. With Microservices, these applications can have a variety of features while still being lightweight and easy to develop. How did it happen? What exactly are Microservices ?

Understanding Microservices

Microservices means dividing the application into smaller, interconnected services. Microservices allow each feature in the application to experience its own development. The Microservices architectural pattern significantly affects the relationship between the application and the database. In Microservices, each service or service has its own database schema.

In addition, services can use the type of database and programming language that best suits your needs. That way, each service will be more optimal. Furthermore, the presence of Microservices allows applications to be more dense and complex but still light. In essence, Microservices is a method by dividing services into smaller but still related parts. In addition, each service can use different technologies.

There are 6 main characteristics of Microservices.

  1. Many components

One of the purposes of using Microservices is so that an application can have some optimal features. Of course, each feature has its own component to run its service.

Therefore, in Microservices there will be many components that are used.

  1. Aimed at business needs

The number of features in an application is related to business objectives, namely to serve consumers as much as possible.

Without Microservices, an application can only run the application optimally for one big purpose, for example transactions for household products.

It is different if there are Microservices, this can be optimized by adding complementary features of household product transactions. An example of that is a house cleaning service.

With Microservices, these new features can run optimally without disturbing the main purpose of the application.

  1. A Simple routing process

The purpose of Microservices is to simplify a process in an application. Because it is divided into small features, if a request occurs, the feature does not need to process too long to sync with other features.

As previously explained, this is because Microservices allow for new features without disturbing the main features.

  1. Can run alone (decentralized)

With Microservices, each feature runs independently without having to synchronize with other features.

That is why each feature in the application has its own developer team that is different from the developers of the main application.

  1. Reducing the risk of failure

Even though they run independently, various features or functions in the application can back up each other.

This means that if there is a failure in a feature, there is a backup through the available database.

  1. Always changing

The convenience provided by Microservices makes it easy for an application to adapt to circumstances.

Various types of gadgets, as well as various updates provided, still make an application optimal because of the Microservices.

Characteristics of Microservices

Advantages and Disadvantages

The advantages of Microservices

Based on the definitions and characteristics previously described, it can be seen that the advantages of microservices are as follows:

  • The application is safer and up to date.
  • Each service is independent and easier to monitor.
  • Easier maintenance.
  • There are no barriers to using new technology.
  • Development can be done from each of its services without disturbing the main features.

The downside of Microservices

Besides having many advantages, of course Microservices also have several disadvantages, including:

  • If there is a change in the entity in the database, the entity on the other service must also be changed.
  • It is often found that it is difficult to implement changes in services, so a careful design is needed.
  • Need high automation in deployment.
