Software as a service (SaaS) is on the path to becoming the de facto model for building, delivering, and operating software solutions. Adopting a multi-tenant SaaS model requires builders to take on a broad range of new architecture, implementation, and operational challenges. How data is partitioned, how resources are isolated, how tenants are authenticated, how microservices are built—these are just a few of the many areas that need to be on your radar when you're designing and creating SaaS offerings.

In this book, Tod Golding, a global SaaS technical lead at AWS, provides an end-to-end view of the SaaS architectural landscape, outlining the practical techniques, strategies, and patterns that every architect must navigate as part of building a SaaS environment.

• Describe, classify, and characterize core SaaS patterns and strategies
• Identify the key building blocks, trade-offs, and considerations that will shape the design and implementation of your multi-tenant solution
• Examine essential multi-tenant architecture strategies, including tenant isolation, noisy neighbor, data partitioning, onboarding, identity, and multi-tenant DevOps
• Explore how multi-tenancy influences the design and implementation of microservices
• Learn how multi-tenancy shapes the operational footprint of your SaaS environment
