1. Multi-Tenancy Architecture Introduction

Let’s start with the definition of tenancy and the differences:

Single-tenancy is an architecture in which a single instance of a software application and supporting infrastructure serves one customer (i.e., tenant).
Multi-tenancy is an architecture in which a single instance of a software application serves multiple customers (tenants).
Hybrid-tenancy is where microservice architectures leverage services that are both single- and multi-tenant to optimize the balance of performance, scale, and security.
