AWS SaaS Factory Monolith to Serverless SaaS Workshop

The goal of this lab is to guide you through a monolith to serverless SaaS migration that provides a more in-depth look at the common moving parts of this problem. Certainly, each solution will have its own unique collection of migration challenges. However, seeing a working example can provide you with insights into patterns and strategies that can help shape your approach to moving your monolithic environment to a multi-tenant SaaS model.

Building Serverless SaaS with Lambda layers

One of the key goals of every software-as-a-service (SaaS) architect, is to create an environment where the complexity of multi-tenancy is largely hidden away from developers. The goal of this session is to introduce frameworks, libraries, and tooling that limits a developer’s need to have any awareness of tenant context. This will free up developers to focus on the features and functionality of their system.

The solution covers a broad range of multi-tenant considerations, including tenant isolation, identity, data partitioning, and deployment. It provides developers with a prescriptive approach the the fundamentals of building SaaS solution with EKS.
