Ultimate Guide to Backend-as-a-Service (BaaS)

You are building an application. Your team have decided on the entire UI/UX of the application. But they are stuck in developing the Backend. This is when BaaS (Backend-as-a-service) can help you. With 6.3 billion smartphone users worldwide, growing at a rate of approximately 7% annually (Build fire), BaaS is emerging as a savior for companies looking for faster app development. This is why the Backend-as-a-service industry is expected to achieve US$27,016.6 million in 2033, a growth of 24% from now.   

With BaaS, you only need to focus on front-end development. BaaS Service providers offer pre-written software for all the backend server activities.   

In this blog, you will learn about the benefits and features BaaS offers to your business, along with its drawbacks. You will also discover when to use BaaS and the upcoming trends in the BaaS industry.  

Backend-as-a-Service: Introduction  

Consider developing an application using BaaS to cook a meal as a chef. A chef must do everything: purchase raw materials, chop vegetables, prepare all the species, and then cook the food. However, if there are helpers who take care of all the activities apart from cooking the food, how easy will it be for the chef to prepare the food?   

The same is true of BaaS: Vendors take care of all the activities like user authentication, database management, remote updating, push notifications, cloud storage, and hosting. Thus, you only must focus on the end-user experience.   

With BaaS, you can integrate the front end with all the backend functionality via APIs and SDKs provided by the BaaS vendor. APIs enable communication between different programs, such as a payment gateway in an e-commerce website. SDKs are kits for building software.  

Backend-as-a-service BaaS is a cloud-based platform used to speed up the development process by outsourcing the backend development process of a mobile or web application. It enables developers to develop better applications faster as they focus on front-end development.  

BaaS also has tools that can help you quickly create backend code.  

What does MBaaS Stands for?  

When you opt for BaaS specifically for mobile application development, it is termed Mobile-Backend-as-a-Service (MBaaS). BaaS and MBaaS are often used interchangeably. However, MBaaS means backend services only for mobile apps, whereas BaaS is for both mobile and web.  

Features of Backend as a service  

• Scalable Backend Provides NoSQL (flexible, document-based) and SQL (structured, table-based) database options for flexible data management.  
• APIs It supports both GraphQL (which lets you request specific data) and REST (standard web protocols to request and send data) for versatile data access.  
• Cloud Code Functions Allows you to run custom business logic scripts on cloud servers, eliminating the need to manage servers.  
• User Authentication This service offers secure user sign-in capabilities, including verifying users' email addresses to ensure they are real.  
• Social Integration This feature connects your app with social media platforms like Facebook, LinkedIn, and Twitter for easy user login and sharing.

Reasons to Choose Backend as a services  

Save Time and Cost  

Hiring a specialized backend developer takes time and costs. You will also need to manage server infrastructure, which can increase the price further.   

BaaS frees you from all these expenses, as a BaaS provider handles all these for you. Plus, you can opt for a pay-as-you-go model. This way, you only pay for the services you need and do not need to maintain an in-house backend team.  

Faster Time to Market  

BaaS service providers offer pre-built and pre-tested backend modules that they integrate via API or SDKs. This allows you to launch applications faster, as you do not have to build the entire Backend from scratch. Thus, you can seize any market opportunities faster.  

Better Focus on Core Functionalities   

The BaaS provider also manages the provisioning, scaling, and maintenance of your cloud infrastructure. This allows you to focus on your application's functionality and user experience.    

Simplified Performance and Scalability  

This benefit is crucial for startups. BaaS comes with features such as load balancing and performance optimization, which enable smooth application performance under varying workloads.  

So, if there is a sudden spike in user traffic, BaaS can handle it without manual infrastructure scaling. Thus, your startup can maintain a smooth user experience in spite of its growing user base.  

Why BaaS (Backend as a Service) is So Useful  

No More Repetitive Code  

With BaaS, you don't have to waste time writing the same setup code for every project. Pre-built modules and APIs handle the routine tasks so that you can get more done faster.  

Consistent Coding Environment  

BaaS gives everyone on your team a uniform coding setup. This makes collaboration easier since everyone's on the same page from day one.  

Focus on the Important Code  

BaaS handles the foundational stuff, so backend developers can zero in on the critical, app-specific parts that make your app unique.  

Ready-to-Go Features  

BaaS includes essential features like authentication and data storage, so you don't have to build these from scratch.  

Clone Apps & Safe Testing  

With BaaS, you can create copies of your app and set up safe testing environments, making it easier to try out different scenarios and run experiments without risking the live app.  

Keep the Focus on Business Logic  

Since BaaS takes care of the backend basics, developers can focus on business logic, improving the user experience.  

Built-In Security and Backup  

BaaS solutions often include security and backup features, so your app stays reliable without much extra setup.  

Better Code Quality  

Since BaaS takes care of backend performance, it helps ensure your app runs smoothly and is built to last.  

Keep Unauthorized Users Out  

BaaS includes strong security measures to prevent unauthorized access, adding an extra layer of protection.  

Data Recovery Options  

Many BaaS providers offer data recovery if something goes wrong, so your data is safe and can be restored if needed.  

Cross-Platform Support  

BaaS makes it easier to build apps for multiple platforms, helping you reach users on mobile, web, and other platforms.  

Downsides of BaaS  

While BaaS has many advantages, it's not perfect for every project. Here's where it might not work as well:  

• Less Flexibility BaaS works well for standard backend needs but can be harder to customize if you need concrete solutions.  
• Limited Customization BaaS solutions are designed for broad use, so they might not allow as much flexibility to adapt to unique needs.  
• Vendor Lock-In If you choose a closed-source BaaS provider, switching providers or making significant changes later can be tricky if they alter their services or go out of business.  
• Best for Shorter-Term Projects BaaS works best for more straightforward projects that don't require constant updates or significant changes. If you're looking for something long-term or highly customizable, BaaS may not be the best fit.  
• Reliability With BaaS, you rely on an outside provider for data management and security. Even well-known services can experience outages or shutdowns, so keep that risk in mind.  

When BaaS is a Good Fit  

BaaS is ideal for apps that need a backend without extreme customization. Most BaaS solutions run in the cloud, which works best for companies already using cloud-based services.  

How BaaS Works  

Most BaaS setups include a few main layers:  

• Foundation This layer contains servers that run the app and back up data.  
• Applications This layer handles requests like user logins and database management.  
• Connections This layer connects the servers to the internet.  

The API and SDK bridge the gap between the user-facing front end and the Backend, which handles data and security. As your app grows, ideally, your BaaS should scale up to handle extra traffic smoothly. However, some BaaS providers may require you to reach out for support if there's a big user spike.  

What Makes BaaS Different?  

Like SaaS or PaaS, BaaS is part of the "as-a-service" trend. Here's how BaaS stacks up against similar options:  

• Platform as a Service (PaaS) PaaS manages the app infrastructure but doesn't include built-in features like user logins or notifications.  
• Mobile Backend as a Service (mBaaS) mBaaS is just for mobile apps, while BaaS can support mobile, web, and other types of applications.  
• Serverless Computing Serverless and BaaS are similar, but serverless apps respond to specific events and can run on any device. BaaS takes care of the backend setup for you.    

BaaS vs. Serverless Computing  

Both BaaS and serverless computing let you focus on writing application code without managing the Backend. Here's how they differ:  

• How They're Built Serverless backends are built around individual functions, each responding to a specific event. With BaaS, the provider manages the Backend, and developers just need to handle the front end.  
• When Code Runs Serverless functions only run when an event triggers them, making them highly efficient. BaaS apps generally run continuously in the background, using more server resources.  
• Where Code Runs Serverless functions can run on any connected device, opening up options for edge computing. BaaS might not offer the same flexibility, although some providers are starting to add this option.  
• Scalability In serverless computing, the application scales up automatically as demand grows. BaaS doesn't automatically scale this way unless the provider offers serverless options.  

BaaS vs. Custom Backend – Key Differences  

You can create a custom backend or use a BaaS framework when building an app. Here's how they compare:  

Custom Backend  

• You build and manage everything from scratch.  
• Pros Full flexibility and customization options.  
• Cons Higher costs and longer development time.  

BaaS (Backend as a Service)  

• It comes with ready-to-use building blocks and code-generation tools.  
• Pros Faster development and quicker time to market.  
• Cons Limited flexibility and standard architecture.  

What Frontend Technologies Can a BaaS Support?  

BaaS works with a wide range of frontend tech, including:  

• Web frameworks React, Vue, Angular  
• Mobile iOS (Swift or Objective-C) and Android  
• Cross-platform React Native, Xamarin, Flutter, Kotlin, Ionic, Unity  

When to Use BaaS  

Great for MVPs and Simple Apps  

BaaS is a cost-effective option for developing a minimum viable product (MVP) or simple standalone apps that don't require complex integrations.  

Suitable for Non-Critical Enterprise Apps  

If you're building an enterprise app that doesn't require extreme security or reliability, BaaS can be an efficient choice.  

Ideal for Frontend Engineers  

BaaS will be helpful to frontend developers who want to skip backend complexities or backend developers looking for a faster, streamlined approach.    

The Future of BaaS
