In this chapter, we learned about continuous integration, delivery, and deployment concepts. The application teams need to build in a lot of maturities when it comes to validating their applications with various tests. The tests should be reliable and should test for all positive and negative scenarios. Test-driven development is a great way to write good code.
We also discussed how we can perform zero downtime and A/B deployments using Cloud Foundry. These strategies provide a better user experience when a new application is put into production, enabling the teams to deliver products and features quickly.
