As we have seen, the serverless architecture provides us a way to develop applications where we are only responsible for writing the logic behind the applications, and relieves us of the worry of how the infrastructure will be managed for running the application and how the application will scale up and down based on the number of requests.

But what powers this architecture? Let's try to spend some time taking a look at how the different components inside the architecture work to provide a serverless development approach toward application development.

As discussed earlier, the serverless approach to application development is made possible through the use of two technologies that have came into existence recently in the cloud-computing landscape. These technologies, BaaS and FaaS, provide the foundations for building serverless applications. Let's take a look at them.
