What is Backend as a Service (BaaS)?
Backend as a Service (BaaS), a cloud-based service model, allows developers to outsource the backend of a mobile or web application. This means that they only need to maintain and write the front. BaaS vendors offer pre-written software to perform activities on servers such as user authentication database management push notifications (for mobile applications) and cloud storage as well as hosting.
Imagine developing an app without a backend as a service provider like directing a movie. Film directors are responsible for managing the camera crews, lighting, set construction, and wardrobe. They also have to film and direct the scenes. Imagine a service that did all the work behind the scenes so the director could just direct the scene and take care of the shooting. BaaS is a service that takes care of all the behind-the-scenes activities (or server-side* functionalities), so the director (the developer), can focus on the action’, or what the end-user experiences.
BaaS allows developers to concentrate on the frontend code. BaaS allows developers to focus on the frontend code. They can use APIs (which allow a program to request another program) or SDKs (which is a kit for building software). To keep an application running, they don’t need to manage servers, virtual machines, and containers. They can therefore build and launch web applications faster.
What is Mobile-Backend-as-a-Service (MBaaS)?
Mobile-Backend-as-a-Service (MBaaS) is BaaS intended specifically for building apps for mobile. MBaaS stands for Mobile Backend as a Service. BaaS and MBaaS are sometimes considered interchangeable terms. However, BaaS services can be used to build mobile apps.
What is included in BaaS?
BaaS providers provide a variety of server-side capabilities. You can take this example:
- Database management
- Cloud storage for user-generated content
- User authentication
- Push notifications
- Remote updating
- Firebase also offers another platform- or vendor-specific functions, such as Google search indexing.
BaaS and MBaaS providers are Google Firebase and Microsoft Azure.
What are the differences between BaaS computing and serverless computing?
BaaS and serverless computing have some similarities. In both cases, the developer needs to only write the application code and does not need to think about the backend. Many BaaS providers offer serverless computing services. There are however significant operational differences between BaaS applications and those built with a serverless architecture.
How the application is constructed
Serverless applications’ backends are divided into functions. Each function responds to events and performs a single action (see What is FaaS). BaaS server-side functions, on the other hand, can be built however the provider wishes and developers don’t need to code anything except the frontend.
When code runs
Serverless architectures run on events. Each function runs only when it is triggered or triggered by an event. BaaS applications are typically not event-driven and therefore require more server resources.
Where code runs
Serverless functions can run anywhere, on any machine, so long as they’re still communicating with the rest. This makes it possible to integrate edge computing in the application’s architecture using running code at the network’s edge. BaaS can’t be used to run code anywhere at any given time, but it could, depending on which provider.
How does the application scale
Serverless architectures are distinguished from other types of architecture by their ability to scale. Serverless computing automatically scales as the user uses it. Cloud vendor’s infrastructure automatically starts up temporary instances of each function when necessary. BaaS applications cannot scale unless the BaaS provider offers serverless computing, and the developer integrates this into their application.
What is the Difference Between BaaS and PaaS (Platform-as-a-Service)?
PaaS offers a platform through the cloud to allow developers to create their applications. Like serverless computing and BaaS, Platform-as-a-Service (PaaS) eliminates the need for the developer to build and manage the application backend. PaaS doesn’t include pre-built server-side application logic such as push notifications or user authentication. BaaS provides more functionality, but PaaS allows developers to be more flexible.
