Which cloud computing model supports service-oriented application development and microservice-based deployment?

The choice of Function as a Service (FaaS) as the correct answer is valid because FaaS is designed specifically to support microservices and event-driven architecture. It allows developers to deploy individual functions or components of applications without managing the underlying infrastructure. This model encourages a service-oriented approach, enabling the rapid scaling and deployment of small, discrete functions that can interact with each other and respond to events.

FaaS abstracts away the server management aspect, allowing developers to focus solely on writing the code for specific functions that perform particular tasks. This aligns perfectly with microservice architectures, where applications are broken down into smaller, loosely coupled services that can be developed, deployed, and scaled independently.

While other models, like Platform as a Service (PaaS), can also support application development and microservices to an extent, they typically provide a broader environment that requires more management compared to FaaS. PaaS solutions allow developers to build applications on a managed platform but might not offer the same level of granularity in deploying individual functions, which is what FaaS excels at.
