A lot of the topics that we covered in this book improve performance at a cost. Your application will become more complicated and harder to understand or reason about. This chapter discusses these trade-offs and how to mitigate their impact.
You should implement many of the approaches that you learned so far in this book only if you require them and not just because they are interesting or challenging. It's often preferable to keep things simple if the existing performance is good enough.
You will learn how to make pragmatic choices about what technologies and techniques you should use. You'll also see how to manage the complexities if you choose to use advanced methods.
The topics covered in this chapter include the following:
- Managing complexity with frameworks and architecture
- Building a healthy culture to deliver high performance
- Distributed debugging and performance logging
- Understanding statistics and stale data
