In the previous chapters, we demonstrated how the new cloud data centers can help us create online resources (virtual machines, Docker repositories, cryptographic keys) in a very easy way, shortening the hardware provisioning cycle from weeks (buying, shipping, and installing new computers) to seconds. We have also seen that there are different providers in the market that can offer us very similar features with different strong points that we can take advantage of when building our systems.

You learned how to create resources through the web interface that they offer, but how scalable is that? Creating resources manually prevents us from keeping an automated inventory of resources that can be used for security purposes as well as manage our infrastructure as if it were software components. In this chapter, you are going to learn how to build resources in the cloud first, through the SDK provided by the cloud data center vendor and then by a software component...
