It has never been a better time to be a developer! Thanks to cloud computing, deploying our applications is much easier than it used to be. How we deploy our apps continues to evolve thanks to cloud hosting, Platform-as-a-Service (PaaS), and now Function-as-a-Service.
FaaS is the concept of serverless computing via serverless architectures. Software developers can leverage this to deploy an individual «function», action, or piece of business logic. They are expected to start within milliseconds and process individual requests and then the process ends.
