Chapter 6. Infrastructure Management

In Chapter 5, we looked at the various infrastructure components and paradigms on which you might run your datastores. In this chapter, we discuss how to manage those environments at scale. We begin with the smallest unit, the individual host’s configuration and definition. From this point, we zoom out to the deployment of hosts and orchestration between components. After this, we zoom out even further to the dynamic discovery of the current state of infrastructure, and the publishing of that data—aka service discovery. Finally, we will go to the development stack, discussing how to create development environments that are similar to these large production stacks.

Gone are the days of one or two boxes that can be manually managed with ease and relative stability. Today, we must be prepared to support large, complex infrastructures with only a few sets of hands. Automation is critical in ensuring that we can deploy datastores repeatably and reliably. Application stability and availability, and the speed at which new features can be deployed, relies on this. Our goals must be to eliminate processes that are repetitive and/or manual and to create easily reproducible infrastructures via standardized processes and automation.

What are good opportunities for this?

  • Software installations, including operating system (OS), database, and associated packages and utilities

  • Configuring software and the OS for desired behaviors and workloads

  • Bootstrapping ...
