We now have a top to bottom application suite that is highly concurrent, ropes in several third-party libraries, and mitigates potential failures with logging and catastrophe recovery.

At this point, you should have no issue constructing a complex package of software with a focus on maintaining concurrency, reliability, and performance in Go. Our file monitoring application can be easily modified to do more, use alternative services, or scale to a robust, distributed environment.

In the next chapter, we'll take a closer look at testing our concurrency and throughput, explore the value of panic and recover, as well as dealing with logging vital information and errors in a safe, concurrent manner in Go.
