Single Tenant – A single instance of the software and supporting infrastructure serve a single customer. With single tenancy, each customer has his or her own independent database and instance of the software. Essentially, there is no sharing happening with this option.
Multi-Tenant – Multi-tenancy means that a single instance of the software and its supporting infrastructure serves multiple customers. Each customer shares the software application and also shares a single database. Each tenant’s data is isolated and remains invisible to other tenants.
