Dealing with failure

As we outlined in Chapter 4, Managing Memory and Space, isolating operations and intelligently monitoring an applications help to minimize the chances of one failed subsystem taking down the larger system.

Note

The following comprehensive article on handling errors with Node.js is recommended:

Peppering a codebase with try/catch blocks and trying to anticipate all errors can become unmanageable and unwieldy. Additionally, what if an exception you didn't anticipate occurs? How do you pick up where you left off?
