Summary

In this chapter, we delved into the crucial topic of secure design patterns for multi-tenancy in shared AWS environments. We kicked off by defining what multi-tenancy is and why it is pivotal in cloud computing, followed by an in-depth discussion on the challenges it poses, such as data isolation, resource allocation, and compliance. The chapter then transitioned into various multi-tenancy design patterns, including the silo, pool, and bridge models, each with its own levels of isolation and suitable use cases. We also provided a guide on choosing the right design pattern based on various factors.
