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. We studied these various concepts, such as enterprise-scale in Azure and Control Tower in AWS.
We also learned how to work with patterns to define the components of the landing zone, starting with connectivity. VPN-connections are still the most used way to connect to public clouds, but enterprises might also choose for direct, dedicated connections. In this chapter the various direct connectivity offers of Azure, AWS, GCP and Alibaba have been discussed. As soon as we have connectivity, we can start managing the workloads in cloud. Main concern for administrators is to keep resources and configurations consistent in different deployments.
Finally, we learned that there's a need for a redundant demarcation model in multi-cloud...
