Monolithic Vs Microservices Architecture
Difference between Monolithic and Microservices. Where do I need to use it and How Best?
Nowadays technology is growing rapidly. Daily new applications are coming. In that, some applications are growing and it reaches a different level to the user. Most of the Applications take time to grow. Lets know the difference between monolithic and microservices architecture, in this blog. Monolithic application has single code base with multiple code base and Microservices application has the split of single codebase into multiple codebases.
Nowadays users are using the web, android, iOS, watch, IoT devices. For Example, Facebook has a Website, Android, iOS App. Just imagine if the developers create a different Codebase (Directly Interacting with the Database Only) for Web, Android, iOS. So, they can’t change small changes everywhere in the code. For that only they created API Calls. In single time, they are creating the API, and design for web, android, iOS. Nowadays every company is approaching same method only. From this, the production is very easy to implement.
Fig: Monolithic vs Micro Services
- Presentation — Design of the Web or App.
- Business logic — Application’s business logic.
- Database access — Getting data from Database
- Application integration — integration with other services (e.g. via messaging or REST API).
Monolithic means composed all in one piece. When developing with a Server-side application, the complete application has a single codebase. This is a very easy method while initially working on it.

- Single Codebase. This is good for starting stage projects.
- Easy to work.
- Easy to deploy. Because single application only
- It can do only horizontal scaling. It can make multiple copies of the same work and can be used with a load balancer.
- The Large scale projects cannot be handle easily.
- It is not easy to understand the code when a new member is working on the project. For understanding, it will take some time.
- When the size project is increasing, then the complexity also will increase.
- If any bug or issue in any modules, it will take down the complete application.
- Adapting to new technologies is very difficult. At the time, from scratch, it needed to change.
- For small updates, the complete application also needs to redeploy.
- The size of the application slows down the startup time.
To split the single codebase into multiple codebases is the concept of the microservices. It will be interconnected with the Frontend application.
- The large scale production can easily handle.
- The multiple codebases can handle. So, it is easy to work as a new member of the project.
- The bugs will not affect the whole system.
- Adapting to new technologies is very easy.
- There is no need to redeploy the entire application. Which module is needed then only can redeploy.
- Vertical scaling is easy in this method.
- Architecture is complicated. Each module needs to maintain different databases.
- Testing is complicated.
- Deployment is difficult
What architecture when needed to Use?
- If the project is small and easy, then monolithic can be used.
- If the project is large and complex, then microservice can be used.
- Every company can use microservice architecture. Once the number of users will increases then microservices can be used.
- Most good work is initially made with monolithic because of small team and less number of users. While it has increased some level then the microservice architecture movement is better.
- Uber started their platform with monolithic architecture. When they increased their services and users, then they converted their architecture into a microservice architecture.
