Conclusion

Congratulations! You've just finished the most technologically focused chapter of this book so far. Please don't go off and think that you have to use each and every technology and technique that has been mentioned—that's not the point. Investigate, evaluate, and choose which of these technologies applies to your own use cases and environment.

Several of the testing practices are part of our technical foundation. Unit testing, non-functional testing, and measuring code coverage are all critical practices for helping build quality into our applications and products from the start. We covered many small but invaluable techniques, such as resource validation, code linting, and formatting, that help make our code base less of a burden to maintain.

We covered a number of different approaches for deployments, including A/B, Canary, Blue/Green, and Serverless. These core techniques allow us to deliver applications more reliably into different environments...
