At this point, the market's rise indicates that many companies will adopt the approach. Yet, to use a platform as a service model, it is crucial to understand the phenomenon from different perspectives.

At this point, one should focus on different types of BaaS, explore the distinct benefits of this approach, determine the examples of BaaS providers, and find out how to choose a BaaS provider. In addition, we will pay certain attention to comparing different models, including BaaS vs. FaaS, BaaS vs. SaaS, BaaS vs. PaaS, and BaaS vs. IaaS. 

What is Backend as a Service (BaaS), and How Does it Work?

BaaS is a cloud-computing approach offering a backend for mobile applications. In a nutshell, this method provides an API and instrument for various computer languages to integrate with their backend. In addition, BaaS exists to provide some crucial services, such as storage, push notifications, analytics, dashboards, and social integration. 

While BaaS is similar to Software as a Service (SaaS), BaaS is most often targeted at developers. In turn, SaaS focuses on end-users. BaaS is often recommended as the solution allowing stable and fast backend development to improve the app’s performance. With BaaS, you do not need to build the backend from scratch. In turn, you can leverage SDKs, APIs, and other existing tools to build a backend that can be scaled. 

In the best-case scenario, when you have a backend provided by a BaaS platform, there is no need to spend too much time maintaining the backend. You can now focus on bettering the user experience or adding features to your app. What is more, BaaS provides features one can deploy across all application types. For instance, consider these approaches:

• SQL and NoSQL scalable databases. BaaS often provides scalable database solutions capable of handling vast amounts of data. 
• Graph and REST APIs. BaaS also offers APIs enabling developers to make custom frontend applications that can easily communicate with the backend servers. 
• Business logic through cloud code functions. BaaS provides cloud code functions presenting developers with the capabilities of adding custom business logic to the apps without needing a dedicated backend server. 
• User authentication. BaaS offers authentication services that enable developers to quickly add user authentication to their applications. This includes login, sign-up, and password reset functionalities.
• Email verification. BaaS services typically provide email verification services to ensure user accounts are valid and authenticated.
• Social integration with different social media platforms. BaaS services offer social integration features that allow developers to integrate their applications with popular social media platforms like Facebook, Twitter, LinkedIn, etc.
