In this chapter, we saw that properly handling faults in an application is the key to ensuring that you can still control the response time of your system and keep it under control in any circumstance. This is true for any system but with the spreading of microservices, it is even more true for systems using this architecture.
Well, defining how your Java EE application is deployed and what is needed to ensure you control all the potential failures of your system is a full time job; we often forget to work on the main codepath of our applications, but doing so ensures that the production deployment and behavior are sane.
This chapter showed you some common patterns used to handle fault tolerance more or less transparently and reliably.
Logging is another important factor when issues start popping up in a system. It will allow you to investigate what happened and identify...
