We have reached the end of this chapter. By this point, we have discussed the eight most common release management models in the IT industry. They are the ITIL, waterfall, iterative, V-shaped, spiral, big bang, agile, and DevOps models. You should now understand the various benefits and drawbacks of each release management model and feel confident about selecting the right one for your project. Moreover, you have been exposed to the amazing benefits that DevOps offers over the previous release management models that came before it. As a result, you have a working knowledge of the history of release management and can draw well-informed conclusions about how each model evolved beyond the next.

This concludes Chapter 3. In the next chapter, we are going to learn about what makes DevOps release management unique. This is important to know because we are going to shift our focus to the DevOps Release Management Model for the remainder of this book.
