If you’re in the world of software development, you may have heard of the term Function-as-a-Service or FaaS for short. But what exactly does it mean? In simple terms, FaaS is a type of serverless computing that focuses on executing small, modular pieces of code in response to events or requests.
How Does FaaS Work?
When a user interacts with a web application or system, events are triggered. These events could be anything from clicking a button to uploading an image. FaaS enables developers to write and update code “on the fly” in response to these events, making it easier to scale the code as needed. When an event is triggered, the corresponding function runs in a container, which is essentially a lightweight environment that only exists for the duration of that function’s execution.
So, why is this useful? For one, it’s cost-effective. With FaaS, you only pay for the exact amount of code that’s executed. That means when a function is idle, it doesn’t incur any costs. Additionally, FaaS enables developers to work more efficiently since they can focus on writing modular code that’s easy to update and scale.
Differences Between FaaS and Serverless
It’s worth noting that FaaS is often used interchangeably with “serverless,” but they are technically two different things. Serverless refers to the broader category of computing where the server is abstracted from the end user, while FaaS is a subset that focuses on event-driven triggers. In other words, all FaaS is serverless, but not all serverless is FaaS.
Benefits of FaaS
In addition to being cost-effective and efficient, FaaS has several other benefits. For starters, since functions are stateless and run in containers, they can easily be scaled horizontally, meaning more resources can be added when demand increases. Additionally, FaaS is ideal for microservices architecture, which breaks down applications into smaller, more manageable components. This results in faster development time, since developers can focus on individual functions, and easier debugging and maintenance.

FAQ
What is FaaS?
FaaS, or Function-as-a-Service, is a type of serverless computing that allows developers to write and update modular pieces of code in response to events or requests. Functions run in stateless containers and are only executed when an event is triggered.
How is FaaS different from Serverless?
Serverless is the broader term for computing in which the server is abstracted from the end user. FaaS is a subset of serverless computing that focuses on event-driven triggers where code is executed in response to events or requests. Essentially, all FaaS is serverless, but not all serverless is FaaS.
What are the benefits of FaaS?
FaaS is cost-effective since you only pay for the exact amount of code that’s executed. It’s also efficient and ideal for microservices architecture. Since functions run in stateless containers, it’s easy to scale horizontally and debug and maintain individual functions.
