Function as a Service (FaaS)
Function as a Service (FaaS) is a cloud computing service that provides a platform in which users can execute their own modular code in response to specific events or triggers without managing the complex infrastructure typically associated with developing an app.
Building an app with FaaS is "serverless," meaning the user does not need to manage their own infrastructure or servers.
Since the cloud service handles the infrastructure, FaaS allows developers to focus on building and deploying independent functions, such as data processing, IoT services, and mobile or web apps.
What are the benefits of FaaS?
There are several benefits of FaaS:
- Cost-effective: Users pay only for the resources they use while their code is running, rather than paying for idle capacity. This can save significant costs compared to other models.
- No infrastructure management: Providers handle the infrastructure management, including scaling and deployment. This allows developers to focus on writing code, rather than managing servers.
- High availability: Providers typically offer high availability and automatic scaling. This ensures that applications remain available and functioning, even under heavy load.
- Improved scalability: Developers can build and deploy applications that can automatically scale to meet changing demand, without the need to manually provision additional resources.
- Flexibility: Developers can build and deploy applications using a wide range of programming languages and frameworks, making it easier to choose the right tools for the job.
