Mastering SaaS Architecture: Key Patterns and Implementation Strategies for Building Scalable Multi-Tenant Systems on AWS

In this AWS re:Invent 2022 session, Tod Golding from the AWS SaaS Factory team explores the landscape of SaaS architecture patterns. He emphasizes that while there's no one-size-fits-all blueprint for SaaS, there are common patterns and strategies to consider. Golding introduces the concept of a control plane and application plane in SaaS architecture, highlighting the importance of building a robust control plane for managing multi-tenant environments. He discusses key patterns in tenant onboarding, identity management, deployment models, isolation strategies, and data partitioning. Throughout the presentation, Golding stresses the importance of flexibility in SaaS architecture, allowing for different combinations of siloed and pooled resources based on business needs and individual microservice requirements. The session provides valuable insights for SaaS architects on how to approach the complex decisions involved in designing scalable, secure, and efficient multi-tenant systems on AWS.
