Let’s discuss the importance of the backend and its applications first. The backend handles server, application, and the database, the three significant aspects of any project. If you consider a registration form, the front end involves UI elements that allow you to provide the relevant data in the fields.

The information provided through the application is stored in the database, which is responsible for data processing. The server located in a different location retracts the data from the database. The interconnectivity between these three essential elements ensures the proper functionality of an application.
Why Should Developers Focus on Backend?
- Various Environments
Organizations prefer to deploy the websites and applications in various environments as per their requirements. Cloud deployment, web server hosting, and seamless operations are essential aspects for companies. The varied hosting environments enable developers to use backend customization for their websites.
- Information Exchange
Backend holds the complete responsibility of information exchange. Any user providing or accessing data from the application required hiccup-free backend functionality. The information submitted by the user will be stored using backend code. Hence backend coding plays a crucial role in information exchange in the business.
- Utilization of Every Frontend Functionality
The user experience of any website will depict the image of the company. The quality of the backend code is one of the significant reasons that ensure website functionalities work flawlessly. The backend code is also responsible, which makes websites vulnerable to security attacks.
Role of Serverless Backend (BaaS Vs Serverless Computing)
(BaaS)Backend as a service is a cloud service model that allows developers to concentrate on writing the frontend application code. Using APIs and SDKs, developers can integrate all the backend functionalities without building the backend.
BaaS vendors offer predefined software for actions implemented on servers, such as user authentication, database management, remote updating, push notifications, and cloud storage and hosting. Serverless computing and BaaS are similar in terms of serverless performance but have significant operational differences.
From construction to code execution, here are differences between true serverless architecture. Serverless applications are broken down into functions and perform the actions only after each function responds to events. In the Baas, server-side functionalities are constructed and provided to the developers.
Serverless architecture runs only when each function is triggered by an individual event. These serverless functions are robust and can run from anywhere as long as the application is communicating. The BaaS approach is not event-driven, as they require more server resources, and running code is dependent on the provider.
