Detailed explanation-1: -The App Engine standard environment is based on container instances running on Google’s infrastructure. Containers are preconfigured with one of several available runtimes. The standard environment makes it easy to build and deploy an application that runs reliably even under heavy load and with large amounts of data.
Detailed explanation-2: -Based on Compute Engine, the App Engine flexible environment automatically scales your app up and down while also balancing the load.
Detailed explanation-3: -The standard environment can scale from zero instances up to thousands very quickly. In contrast, the flexible environment must have at least one instance running for each active version and can take longer to scale out in response to traffic. Standard environment uses a custom-designed autoscaling algorithm.
Detailed explanation-4: -Google App Engine provides four possible runtime environments for applications, one for each of four programming languages: Java, Python, PHP, and Go. The environment you choose depends on the language and related technologies you want to use for developing the application.
