Summary

In this chapter, we reviewed the criteria for how a company should evaluate the IDP that they will choose. We discovered that there are not only technical factors at play in this choice but also regulation policies for specific businesses playing an important role. We reviewed all the technical aspects that should affect the choice of which IDP to use.

We also had the opportunity to describe, from a very high-level point of view, some of the IDPs that have a good standing on the market.

In the next chapter, we are going to move a step further and a level deeper: we are going to describe in detail how one of the most important IDPs works, look at its features, discuss the advantages and disadvantages of adopting it, and see the benefits an enterprise can obtain by leveraging features that are built on top of the OAuth protocol when choosing this IDP. We are going to have a closer look at AAD.
