Why Transition From Monolith to Microservices?

**Microservices architecture **is a way of creating applications through loosely coupling services. Every service represents a system component that can be created and maintained separately, executing an independent business goal.

Microservices are basically small services that work independently as part of a more complex system. They are easy to manage, portable, and created in order to accomplish the business objectives of the application. They can be developed with the use of different programming languages, like Node.js, PHP, Python, Java, etc.

Why Transition From Monolith to Microservices?

When should you adopt microservices? When is monolith architecture better? How to transition?

Microservices architecture is a way of creating applications through loosely coupling services. Every service represents a system component that can be created and maintained separately, executing an independent business goal. In this article, we’ll discuss why you should transition from monolith to microservices.

Monolith Architecture

The traditional application architecture is monolithic. The monolithic approach means creating the application as a single unit that contains all the functional components, including database operations, business logic, background processing, etc. They are all deployed together at the same time and running on the same servers.

There are several benefits that monolith architecture brings. First of all, it’s very convenient to develop a simple application as everything’s in the same language and framework.

Second, they are easy to test. End-to-end testing can be performed by simply launching the entire application.

Finally, there’s only one application being released every time something new is added.

However, all these benefits carry their own difficulties. Deploying the entire application when you only need to make a small change is too complicated and unnecessary. This wouldn’t be a problem if you migrated from monolith to microservices.

When there’s a small bug that only requires the change of only a few lines of code, you need to create a new build for the entire system and deploy it again. This can take days, sometimes even weeks.

Scaling is an even bigger issue. Scaling just a part of the system is impossible — you have to scale the entire system instead. This makes the creation of innovation much more difficult. Organizations struggle with becoming agile because every action takes too much time and effort.

Microservices and Data Management - DZone Microservices

Introduction

For pure frontend developers who doesn’t have much exposure to backend or middleware technology, microservices are a vague thing. They might have high-level introduction. So, let us have some deep understanding of what microservices are, and how it is different from monolithic application data management.

Monolithic and Microservice

In a monolithic application, all the stakeholders like all the business logic, routing features, middle-wares and Database access code get used to implement all the functionalities of the application. It is basically a single unit application. It has a lot of challenges in terms of scalability and agility. On the other side, in a microservice, all the business logic, routing features, middle-wares, and database access code get used to implement a single functionality of the application. We break down the functionalities to the core level and then connect to related services. So, the functionalities are actually dependent on related services only and does not get affected if there is an issue with other services. This helps to make the application agile, flexible, and highly scalable.

Why Microservices

Independent DB for the Services

The very first important thing associated with microservices is that each functionality requires its own database and never connects to the database of other services. In a monolithic service, since you have a single database. if something goes wrong with it then the whole application gets crashed. But in microservice, since we have an independent database for each service, in case of any problem with any particular database, it certainly does not affect other services and your application does not crash as a whole.

No Dependency on Schema

We have many services in our application and each service requires its own database. Hence, each database has its own schema or structure. But, if any service is connected to other service and shares the data and during development, the source database changes its schema and does not update the dependent services, then the service will not function correctly and may crash. So, there should be no dependency on databases.

Performance

Depending on the nature of service, we choose the appropriate type of DB. Some services are more efficient in specific database. So, creating a single database for all the services in the application might affect performance. In Microservice, since we have individual DB for each of the service, it is quite flexible, independent, and functions efficiently.

Data Management

Unlike the monolithic approach, in microservice, each functionality or service connects to its own database and never gets connected to other database. So, the big question arises of how we communicate between two services. It is quite generic in an application that we require to get some information based on the combination of many service outputs. But as a thumb rule, services dont communicate. Then what is the solution to this issue? Let us see, how data communicates between the services.
