GCP: Build and Deploy with Cloud Run and App Engine

Cloud Run and App Engine are Platform as a Service (PaaS) products that enables you to deploy your microservices or web applications. The major difference between them is that Cloud Run uses container images to be deployed so that they are platform agnostic where as App engine is a standard deployment. Both PaaS solutions offer automatic resource provisioning, scalability, rate controls and traffic monitoring.

Setting up gCloud:

//Authorize with your gcp account and ensure right project is selected
$ gcloud init 

//list all the accounts
$ gcloud auth list

$ gcloud config list project

Cloud Run:
