On this chapter we have seen how we should align our resources (engineers) to deliver low cost and high impact IT systems. We have seen how a poor communication can lead into a defective release process deadlocking our rollouts and making the system quite inefficient from the business point of view. Through the rest of the book, we are going to look at tools that can help us not only to improve this communication but also enable our engineers to deliver more top quality functionality with lower costs.

The first of these set of tools are described on the next chapter: the cloud data centers. These data centers allow us to create resources (VMs, networks, load balancers...) from their pool of resources in order to satisfy our needs of specific hardware, at a very reasonable price and flexibility. These type of cloud data centers are being adopted more and more by the modern (and not so modern) IT companies, which is leading to the creation of a set of tools to automate pretty much everything around the infrastructure.
