What is BaaS? | Serverless vs. Backend-as-a-Service

What is BaaS?
Developers can simply focus on creating and maintaining the front end of a web or mobile application by using the cloud service model known as backend-as-a-service (BaaS). BaaS providers offer pre-written software for server-based tasks including user authentication, database management, remote updating, and push notifications (for mobile apps), in addition to cloud hosting and storage.

backend as a service
Consider creating an application without a BaaS provider as producing a film. In addition to actually directing and filming the scenes that will be in the movie, a director is also in charge of organizing the camera crews, lighting, set construction, costume, actor casting, and the production timeline. Consider if a service handled all the behind-the-scenes tasks so that the director only needed to direct and shoot the sequence. That's how BaaS works: Thus that the director (the developer) may concentrate on the "action," or what the end user sees and experiences, the vendor takes care of the "lighting" and the "camera" (or, the server-side* functions).
Developers can concentrate on building the code for front-end applications thanks to BaaS. They are able to incorporate all the backend functionality they require without constructing the backend themselves thanks to the BaaS vendor's APIs (which are a mechanism for a program to request something from another program) and SDKs (which are building blocks for software). In order to keep the program operating, they are also exempt from managing servers, virtual machines, or containers. As a result, they can create and launch web applications (including single-page applications) and mobile applications more quickly.

In the Internet client-server concept, "server-side" refers to everything that is housed on or occurs on a server as opposed to a client.

What is Mobile-Backend-as-a-Service (MBaaS)?
The BaaS known as Mobile-Backend-as-a-Service (MBaaS) is designed exclusively for developing mobile applications. Although some sources believe the terms BaaS and MBaaS to be essentially identical, BaaS services are not always required when developing mobile applications.

What is included in BaaS?
BaaS providers offer a number of server-side capabilities. For instance:

  • Database management
  • Cloud storage (for user-generated content)
  • User authentication
  • Push notifications
  • Remote updating
  • Hosting

BaaS and MBaaS providers include Google Firebase , Microsoft Azure, BackSwift.

What differences exists between serverless computing and BaaS?
BaaS and serverless computing share some similarities in that both require developers to focus solely on writing application code without considering the backend. Moreover, a lot of BaaS suppliers provide serverless computing services. A genuine serverless architecture and apps developed with BaaS, however, operate very differently.

How the application is built up
Serverless applications' backends are divided into functions that each respond to events by carrying out a single action (see What is FaaS?). Developers only need to worry about developing the application's front end when it comes to BaaS server-side functionalities, which are built whatever the provider chooses.

Code execution
Event-driven architectures, or serverless architectures, operate in reaction to events. Each function only ever executes when a specific event triggers it; otherwise, it does not. BaaS-built applications are typically not event-driven, requiring greater server resources.

Where code is run
Edge computing can be incorporated into the architecture of the program by running code at the network's edge since serverless tasks can be executed from any location on any machine, as long as they are still in communication with the rest of the application. BaaS may not always be configured to let code to execute anytime, anyplace (although it can be, depending on the provider).

The application's scalability
One of the key characteristics that sets serverless systems apart from other types of architecture is scalability. While using serverless computing, the application scales up automatically as consumption grows. The architecture of the cloud vendor starts up temporary instances of each function as needed. Unless the BaaS provider additionally offers serverless computing and the developer incorporates this into their application, BaaS applications are not configured to scale in this manner.

What is the difference between BaaS and Platform-as-a-Service (PaaS)?
PaaS offers developers a platform in the cloud on which to create their applications. Platform-as-a-Service (PaaS) does away with the requirement for the developer to create and maintain the application backend, much like serverless computing and BaaS. Push notifications and user authentication are two examples of server-side application logic that is not included in PaaS. While BaaS offers more capability, PaaS gives developers more flexibility.
