Release It!, 2nd Edition

Wrapping Up

We looked at the interconnect layer in this chapter, where instances come together to form systems. Load balancing, routing, load shedding, and service discovery are some of the key issues to consider when building this layer. Depending on your organization, you may have existing solutions in place to plug into. That can be a big help, because some of the most powerful tools require operational support that makes them costly to support by a single team.

Next, we continue zooming out to look at control over this whole extended mélange of application instances and infrastructure tools. We will see what it takes to deploy, monitor, and intervene with systems running in production.
