Creating a function and working with metrics and logs

Function-as-a-Service is the cornerstone of cloud-native architecture. Functions enable self-sufficient, full-stack teams to focus on delivering lean business solutions without being weighed down by the complexity of running cloud infrastructure. There are no servers to manage, and functions implicitly scale to meet demand. They are integrated with other value-added cloud services, such as streams, databases, API gateways, logging, and metrics, to further accelerate development. Functions are disposable architecture, which empower teams to experiment with different solutions. This recipe demonstrates how straightforward it is to deploy a function.
