The contemporary stage of technological development finally made serverless architectures happen. These models help to build and execute applications and possess numerous advantages to companies, including

  • Perfect business implementations and control of infrastructure
  • Keeping a better level of management
  • Compliance with uptime requirements, plan availability, and SLAs
  • Minimizing operational expenses and better budgeting
  • Utilizing applications and services from third parties
  • Excludes extra personal engagement

Relying on third parties, serverless architectures help organizations effectively manage their computing environment, delivering the needed pieces of code for a reasonable price.

In this article, we’ll reveal the peculiarities of two main serverless architectures, known as BaaS (Backend as a Service) and FaaS (Function as a Service). These two cloud computing services serve different aims and have a diverse set of advantages and disadvantages.

We’ll guide you through BaaS vs FaaS differences in this article.

Executive Summary

This FaaS vs. BaaS overview demonstrates the key strengths and weaknesses of these two serverless architectures. Our aim is to let you make a more informed decision on picking a BaaS or FaaS model that will take the load of complex and time-consuming server-side tasks. Also, we will provide examples of BaaS and FaaS to show you how these serverless architectures cope with real-life challenges.

Differences between BaaS and FaaS

The Programming tools visualization.

Mainly, the difference between BaaS and FaaS is the purpose of adoption.

BaaS deals with backend functionality as a whole, but FaaS addresses microservices in applications only, responding to the events that occur. In other words, backend functionality is a constant thing, but microservices are certain events that appear from time to time and need a quick reaction. That’s why the set of technologies that make BaaS and FaaS work is so different.

Among other differences between FaaS and BaaS, unequal functionality complexity is striking.

Since BaaS addresses numerous backend services, it contains the necessary pieces of code to build push notifications, geolocation, email verification, and many other functions.

In its turn, FaaS is capable of dealing with simple events only. It cannot address complex tasks but provides the needed speed and accuracy in managing microservices.

What is BaaS (Backend as a Service)

In essence, BaaS is an innovative cloud model widely adopted for developing mobile apps and websites alike. This third-party service is the set of tailor-made backend features, providing the basis for fully functioning applications that need only frontend maintenance. This way, the execution model saves time for your team for numerous other tasks rather than testing and deployment.

How Can Backend-as-a-Service Help Businesses and Accelerate Software Development?

Among the concrete functions backend developers can deliver quickly — BaaS offers assistance to database management, push notifications, user authentication. Being applicable to game apps, single-page applications, websites, chatbots, and various industrial apps, it grants you access to a bundled infrastructure with ready-to-use APIs and SDKs behind. With this service, you can forget about your app’s server-side tasks and dedicate more time to business-critical tasks.

Recently, there appeared mBaaS, or mobile Backend as a Service, that addresses the backend tasks for mobile application development. Like classic BaaS, mBaaS lets you maintain only the frontend part, totally supporting the backend services in a mobile app.

Pros of BaaS

Advantages of using BaaS.

The greatest advantage of BaaS is saving time on frontend.

Earlier, companies had no choice but to invest resources heavily in both backend and front development. But with BaaS services, it’s possible to reduce your workload at least by half, leading to productivity gains and higher ROI. By providing cost-effective solutions for a full-fledged infrastructure, BaaS lets you spend less time on backend and concentrate on more complicated software development tasks.

Also, it lets you outsource backend tasks to BaaS provider. In practice, it means faster development and unnecessary to deploy backend features from scratch. What’s more, you can manage two great issues at once: scaling cloud infrastructure and accelerating backend development. With BaaS supporting your backend, you can address critical tasks in business and technological aspects more efficiently.

Cons of BaaS

Notwithstanding its applicability, BaaS has limited flexibility. Like any tailor-made solution, this service is not adjustable as custom coding. Some packages and platforms offer the ability to add your own feature to overcome this limitation, though. In any case, getting a high-quality BaaS is the point of carefully picking the solution that suits your business aims right away.

Top BaaS Providers

On the market, several tech providers are offering high-quality BaaS services. In this section, we’ll briefly present some of them. In our blog, you can find a full list of the best serverless backend providers in 2021-2022. And remember the main rule: don’t just fall for loud names. Your choice of a BaaS vendor must come from your needs and nothing else.

What is FaaS (Function as a Service)

FaaS is a serverless approach with ready-made pieces of code. It’s useful for developers to work on the fly or respond to the events and provide microservices.

The platform enables running self-contained functions (or already designed code snippets) in the cloud. Being an event-based model, FaaS frees your developers from executing the code and lets them work on other important tasks.

Pros of FaaS

The greatest strength of FaaS is at scaling code at the highest cost-effectiveness. With the already designed codes, you can save significant resources on creating them from scratch.

Also, FaaS is useful for the real-time processing of data. Thanks to this service, your developers don’t need to interact with page elements to update the code. All they need is to pick a temporarily running container in the existing pod. These ephemeral containers provide smooth user integrations and manage workloads and troubleshooting optimally.

Cons of FaaS

Notwithstanding its scalability and speed, FaaS doesn’t address the core business aims of your business. It can help you maintain and manage some micro-events, but it does not apply to complex backend tasks.

Also, the FaaS platforms, by automatically running your code without asking you for provision, create a sense of the lack of control. This is especially critical in crisis events when the company has to get manual access to the infrastructure.

Top FaaS Providers

Azure, Google, and AWS are the biggest FaaS providers that concentrate on configurability. It means that their services are closely linked to other parts of their ecosystem. That involves a significant level of generality and calls for choosing based on the exact system you already use in your company.

AWS Lambda

Google Cloud Functions

This service lets you treat all Google and third-party cloud services as building blocks, running your code with zero server management. The features include simplified developer experience and increased developer velocity, pay only for what you use, and avoidance of lock-in with open technology. The exact pricing for this FaaS solution depends on how long your function runs, how many times you use it, and how many resources you provision.

“When using BaaS, developers can concentrate on the business logic and only work on the parts that make money, without bothering with the tech underlayers,” explains Acropolium’s CEO Oleksii Glib.

Why Choose BaaS over FaaS

In simple words, having building blocks and code generation tools for your backend as a whole is always better than simply knowing how to manage micro-events. That’s why the question of choosing backend-as-a-service or function-as-a-service has a straightforward answer.

It’s better to pick BaaS because it addresses more complex tasks and delivers more sophisticated results.

The business advantages of BaaS include greater productivity and outsourcing a huge amount of tasks related to cloud management. Generally, getting the platform is cheaper than hiring a skilled backend engineer, not to mention the faster time to market a hired professional cannot always guarantee.

For example, a BaaS provider managed to save $500k for a Vantage SaaS company.

For reaching the maximum benefit from picking BaaS over FaaS, ensure your tech vendor can deliver this list of components:

  • APIs
  • Database
  • Cloud Code Functions
  • Infrastructure
  • Content Delivery Network
  • Caching
  • Geolocation
  • User authentication
  • Third-party integrations
  • Social integration
  • Push notifications
  • Data management

In addition, check if a serverless vendor is compliant with GDPR and HIPAA. Otherwise, choosing BaaS over FaaS will not bring you benefits. That’s why we encourage you to make a BaaS and FaaS providers comparison to pick the service that will fully address your needs.
