Multi Tenancy Architecture Basics
Multi-tenancy is an architecture in which a single instance of a software
application serves multiple customers. Each customer is called a tenant.
Tenants may be given the ability to customize some parts of the
Multi-tenancy can be economical because software, hardware and
maintenance costs are shared. It can be contrasted with single-tenancy,
an architecture in which each customer has their own software instance
and may be given access to limited Network and applications.
A software-as-a-service (SaaS) provider, for example, can run one instance
of its application on one instance of a database and provide web access
to multiple customers. In such a scenario, each tenant's data is isolated
and remains invisible to other tenants.
