What does Function as a Service (FaaS) primarily help avoid?

Function as a Service (FaaS) primarily helps avoid the complexity of building infrastructure. FaaS allows developers to focus on writing code without the need to manage the underlying servers or the infrastructure that runs the code. This abstraction simplifies the development process significantly, enabling developers to deploy individual functions without worrying about the server setup, scaling, or maintenance tasks typically associated with traditional server-based applications.

This model of computing is particularly attractive for microservices architectures, where applications consist of small, independently deployable units. By utilizing FaaS, organizations can quickly iterate on their applications and deploy new features without the overhead of managing hardware or configuring servers, which can be time-consuming and complex.

While operational costs, dependence on physical servers, and application design can also be influenced by FaaS, the primary advantage is the reduced complexity in infrastructure management. Consequently, organizations can allocate more of their resources and focus towards development and innovation rather than the intricacies of infrastructure.
