Summary

In this chapter, we have designed and set up our landing zones in the different major cloud platforms. We have learned that the foundational principles might be comparable, but the actual underlying implementation of the landing zone concepts do differ.

Next, we explored the principles of Infrastructure as Code and Configuration as Code. With tools such as Terraform, we can manage multi-cloud from one code base using configuration policies that have been abstracted from the resource code. We then learned how to define policies and how to apply these to manage our landing zones. Finally, we learned that there's a need for a redundant demarcation model in multi-cloud. This all adds up to the concept of BaseOps: getting the basics right.

Part of keeping the basics right is making sure that our environments are resilient and performing well. That's what we will be discussing in the next chapter, which is all about creating availability and scalability in the...
