There is growing interest in multi-tenant architecture today because of an increase in cloud computing and SaaS business models. While SaaS delivers software applications over the Internet, multitenancy allows multiple users to share resources, thereby speeding up and streamlining scaling. It optimizes public cloud use, reduces costs, and provides consistent access. Plus, when new features are added, everyone benefits in a multi-tenant system, unlike single-tenant systems where updates benefit only one client. Tech giants like Microsoft, Salesforce, Oracle, IBM, and others are also building their applications using SaaS multi-tenancy architecture.
