US Patent 11182219 SaaS infrastructure for flexible multi-tenancy

Techniques for implementing a software-as-a-service (SaaS) infrastructure that supports flexible multi-tenancy are provided. In various embodiments, this SaaS infrastructure employs a hybrid design that can flexibly accommodate both single-tenant and multi-tenant instances of a SaaS application. Accordingly, with this infrastructure, a SaaS provider can advantageously support high levels of isolation between certain tenants of its application (as dictated by the tenants' needs and/or other criteria) while keeping the marginal cost of operating the infrastructure as low as possible.
