Motivation

"create Order out of Chaos"

Sample architecture(XSA) on SAP Cloud Platform, Cloud Foundry

Test this!

Getting things to run

maven/npm

Environment

Security

Database

Downstream dependencies

Application Runtime

App Binaries

Networking

Platform services

There are many ways to get things done

"let's just disable security temporarily"

set JAVA_HOME=/jre1.8.0_121
...
doSomeLogic();
// commented out for testing
// callOtherSystem();
...

Snowflakes

Dev/Prod Parity

Test environment qualities

"Test-Environment-as-Code"

https://blogs.sap.com/2018/06/28/local-test-environment-as-code/

  • consistent
  • easy to set up
  • centrally managed
  • The Test Environment is your product
  • The development team is your customer

Test-Environment-as-Code

..now back to Cloud Foundry

  • open-source PaaS ("Linux of the Cloud")
  • handles building, deployment and monitoring of apps (Java, Node.JS and many more)
  • provides multiple services for the apps to use
  • hides complexities of underlying Infrastructure
