What is Backend as a Service?

As innovation and competition increase, developers are always on the lookout for ways to work faster and lower costs. The demand is being met by Backend as a Service (BaaS) platforms. These services free up programmers to focus on the client-side of their apps while allowing these new resources to handle the backend services.

As application developers continue to look for faster and more efficient ways to get new apps to market, BaaS is becoming a more popular option for powering backend services. BaaS automates the backend development of an application and handles all of the cloud infrastructure. Instead of requiring developers to start from scratch creating and perfecting backend services, BaaS offers tools to simplify the process allowing developers to focus on the front end features and functionality such as user interfaces and client-side logic and leave behind the scenes tasks like database management, user authentication, and hosting to a third party. In apps using BaaS, APIs (unified application interface) and SDKs (software developer kits) are used to connect applications to the cloud-based backend services rather than creating and maintaining a backend on a client’s on-site servers.

What Are Front End (Client-Side) Services

Most app users pay little attention to back end services. What they see and interact with is the front end. The front end is what we often think of as the user interface. Users interact with the front end or UX (user experience) through a graphic interface that may include graphics, buttons, input fields, and other features. As users interact with a well-designed application, they usually have no idea how much work is going on behind the scenes, on the backend, where much of the heavy lifting occurs. The front end services are designed to seamlessly interact with the backend calling on services to complete tasks initiated through the user interface.


What Are Backend (Server Side) Services?

Whether app developers handle these functions themselves or outsource them to a third party, several critical operations need to happen for an application to work correctly. The average user pays little attention to how these work and who handles them, so it makes sense for developers to find the most efficient and cost-effective solutions. In the past, before BaaS solutions were available, this work was all left in the hands of the developer. This took time and attention away from the development of the unique aspects of the application and created a considerable amount of redundant work.

Some of the backend services required for the proper functionality of a mobile or web app include:

  • Database management
  • Cloud storage (for user-generated content)
  • User authentication
  • Push notifications
  • Remote updating
  • Hosting
  • Social Network Integration
  • File Storage and Sharing
  • Location Services
  • Messaging and Chat

Benefits of a Backend as a Service

Development Speed

BaaS saves a significant amount of time in the development process. There is no need to create and set up a customized backend for each app. This work is already taken care of by the BaaS. This can significantly reduce the total time required to get an app from the initial concept to marketability.


When launching a new application, it is difficult to know, for sure, how much it will grow and how much capacity you will need to serve all of the users properly. With BaaS, there is no need to guess. Your backend service can quickly scale to handle an increased load with no additional work on your end.


The cost of developing, customizing, and hosting your own backend services can quickly become the most expensive aspect of app development. Because BaaS providers focus on only the backend, they can provide the required services at costs far less than doing it yourself. This is especially true if you consider the time savings and the cost of hiring or contracting backend developers.

Mobile and Tablet Optimization

BaaS platform providers have already invested time and resources into optimizing data and network use for mobile apps. They have also done the difficult work of reducing fragmentation issues found when working across multiple platforms and devices.

Increased Focus on Frontend Development

With all backend services being attended to by a BaaS provider, developers can keep their focus on the unique aspects of the app and improve user functionality.

Expanded App Feature Sets

Since BaaS platforms come with advanced backend features already tested and functional, frontend developers have many more features to harness for development. There is no need to work with backend developers to include app features like authentication, geo services, file storage, and messaging.

Service Providers

As the popularity of BaaS increases, more companies are entering the market with competitive solutions. It is now merely a matter of finding a platform that has the best combination of features, reliability, and pricing to fit your needs.
