Choosing a multi tenant or single tenant environment can be tricky. Single tenant architecture uses a software application and a database for each tenant (client), whereas multi-tenant means an architecture in which every instance of software app is serving more than one tenant (client).  With single-tenancy, clients can’t share the same database or application between them. Single-tenant architecture has a specific design, making it unique since it allows only one instance per every B2B SaaS environment. The multi-tenant architectures have become the standard within the enterprise SaaS environments, enabling its users to make significant customizable changes within their operating environment.
