SaaS presents developers with a unique blend of architectural challenges. While the concepts of multi-tenancy are straightforward, the reality of making all the moving part work together can be daunting. For this session, we’ll move beyond the conceptual bits of SaaS and look under the hood of a SaaS application. The goal here is to examine the fundamentals of identity, data partitioning, and tenant isolation through the lens of a working solution and highlight the challenges and strategies associated with building a next-generation SaaS application on AWS. We’ll look at the full lifecycle of registering new tenants, applying security policies to prevent cross-tenant access, and leveraging tenant profiles to effectively distribute and partition tenant data. The goal here is to connect many of the conceptual dots of a SaaS implementation, highlighting the tradeoffs and considerations that will shape your approach to SaaS architecture.
