From the Simple to the Complex: Monolith vs. Microservices

Monolith vs. microservices: a long path from a simple structure to a complex architecture.

Working in the software development industry, I often see articles on monolith pros and cons, microservices pros and cons, monolith vs. microservices, etc. — and much less often about the correct transitions between architectural approaches and their interactions. While projects can grow rapidly or dramatically change their course of development, you need to know when and what architectural approach will help support the system.

This article is for those for whom the monolith hasn’t solved problems and only aggravates all processes. It will also come in handy for those who are just getting acquainted with microservices. I will not say which is better, but I will share my experience of migrating from a monolithic to a microservice architecture.

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.

Microservices Architecture

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.

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.
