SaaS offers developers a unique blend of architectural challenges. Supporting a multi-tenant model often means rethinking your approach to almost every layer of your architecture. Onboarding, security, data partitioning, tenant isolation, identity—these areas must be factored into how you design, build, and deploy a SaaS solution. The best way to understand these SaaS architectural principles is to dig into an example. In this workshop, we expose you to the core concepts of SaaS architecture then dive into a reference SaaS architecture, where we show you the moving parts of a SaaS solution.
