System operators (see Figure 5-1) are chartered with deploying and maintaining the compute, storage, and network resources required to support the users of our applications. The range of tools and techniques available to these professionals is enormous, but the most interesting trends for our purposes here are software-defined infrastructure (SDI) and the DevOps tool market.

SDI performs the task of setting up individual hosts, clusters of hosts, and even global-scale service platforms with only a set of scripts. The technology enabling most of this power came with advances in cloud computing, but the market is now so dynamic that tools and techniques exist for using SDI in cloud, on-premise, or hybrid deployment situations. These deployments can include components of every capacity and at every price point. In many cases, several types of storage are available, ranging from the very fast and expensive to the slow and inexpensive.
