SaaS has several characteristics that set it apart from other services:
- SaaS allows the access and use of commercially available software through a remote, network, or internet connection. This means that the software is not installed in the subscriberâ€™s computer, but rather on the SaaS providerâ€™s server. This also makes the software accessible to the subscriber regardless of his or her location.
- SaaS provides commercially available software, not custom made software, meaning that a particular software service is made available to multiple clients, so customization is limited to only what the software or SaaS provider allows.
- The SaaS provider shoulders the responsibility of updating the software, and subscribers can request updates, upgrades, and additional features.
Regarding implementation, SaaS architecture is classified into four â€œmaturityâ€ levels based on factors such as configurability, multi-tenant efficiency, and scalability.
- Level 1 is the â€œad-hoc/customâ€ level, in which a modified version of a particular piece of software is offered to subscribers, which is then run on the providerâ€™s host server. This level is requires the lowest maintenance.
- The second level offers more customization and allows subscribers to configure the metadata of a program. This then allows a customized version of the same software, based on the needs of the subscriber.
- Multi-tenant efficiency is added to the third maturity level, which means that the SaaS servers are made more conducive for subscribers to use separate instances of a single application.
- The fourth and most â€œmatureâ€ SaaS architecture offers all four factors, with the service reaching optimum efficiency.
