What is the difference between Microservices and Monolith Architecture?

Generally, applications consist of three parts; the client part, that is, the part that is shown to the user and where the user's operations are performed, can be thought of as the web page and mobile application. The server application part can be thought of as the structure where all requests are managed and the necessary algorithms are located. The database part is where we save and store the data. When we consider the server part which consists of a single piece, you can see that the whole system is moving. The entire application is affected when it starts or stops, or even when it crashes. In other words, the application acts as a single piece throughout its life. For any update, change or upgrade, we need to intervene in the entire application.

 

 

In contrast, a microservice refers to a functional small part of a single job-oriented application. A service designed as Microservice can be reused in more than one project (application) or in different projects depending on the need. Dependencies between services are minimized in accordance with the loose-coupled principle. When single-responsibility services conform to a standard, they are not affected by changes to other services.

In fact, the microservice approach has important advantages such as scalability, flexibility, and agility. This is why many important and big companies such as Netflix, Google, Amazon, and Spotify have successfully completed the transition from their monolithic architecture to microservice architecture. Meanwhile, many companies are starting to use this method or converting their existing systems to this architecture.

 

Monolithic architecture pros

Easy development and deployment

Monolith applications have existed since forever. Numerous tools do facilitate easy development and deployment strategies. Developers need to perform a single chunk of deployable code instead of making updates in separate entities.

Performance:

Better performance is a crucial advantage of monolith applications over microservices. A microservice-based application may have to make 100 different API calls to 100 other microservices to load one UI screen whereas, in the monolith, one API call can serve the same purpose because it has a centralized code and memory.

 

Microservice architecture pros

Better Organization

Since the entire code base is broken down into smaller services, it is relatively better organized. The microservices have a particular job and are not dependent on other components.

Increased Agility

With microservices, individuals of a team can work on individual modules. Each individual can build a module and deploy a module independently by reducing the team’s operational friction and increasing the software delivery’s agility.
