Understanding the Multitenant Nature of SaaS Solutions

SaaS applications are often multitenant solutions; that is, within the cloud, two or more companies may share the same server resources, as shown in Figure 2-2. Depending on their size and fees, customers may also share database resources. Further, depending on the SaaS provider, customizing a multitenant solution may be difficult, expensive, or impossible.

An illustration shows a large cloud in which a server representing SaaS provider (multitenant) provides access to client 1, client 2, client 3, and client 4.
