Software as a Service Definition

Software as a Service SaaS is a cloud computing service model that delivers software applications over the internet to users on a subscription basis.

In the SaaS model, the software is hosted and maintained by a third-party provider in the cloud, eliminating the need for users to install, manage, or own the software locally.

Software as a Service offers on-demand access to multi-tenant applications, with users paying recurring fees for usage. These cloud-based applications are scalable, customizable, and accessible across devices and operating systems. SaaS providers handle automatic updates and maintenance, reducing IT overhead for organizations.

Overall, Software as a Service provides a flexible and cost-effective solution for accessing and using softwares with the added benefits of accessibility, scalability, and reduced infrastructure management responsibilities.

Three different delivery SaaS models

SaaS provides you with three different secure delivery models. The best fit depends on your needs.

1. SaaS - Pay per use - Software as a Service is the most common delivery model. This means you choose to work with the software via the standard secure (https) installation on the website domain, pay only per user, and store your data in a shared cloud database. Normal user license rates apply. You can interface with the software application, such as CRM and collaboration tools, and its data using URL connections (http:// and ftp://) and SOAP/WSDL services. If you choose our SaaS delivery model, no contract will apply other than the End-User License Agreement (EULA), which is applicable when you pay for the user license and use the software.
2. PaaS - Choose your database dimensions - Platform as a Service is the second standard delivery model. This means you can access the software through a highly secure, tunneled installation (VPN) on the website domain and store your data in a cloud database or on your premises. You can choose the database dimensions and location. Interfacing with the software application (CRM, collaboration tools, etc.) and data using URL connections (http:// and ftp://) and SOAP/WSDL software services. Special rates apply for this delivery model. If you choose our PaaS delivery model, another contract will apply in addition to the End-User License Agreement (EULA) when you pay for the user license and use the software. The contract will cover custom database settings, data availability, and backup delivery.
3. IaaS - Choose your hardware and software dimensions - Infrastructure as a Service is the third delivery model. This means you can access the software via a secure, tunneled installation (VPN) on the website domain and store your data in a cloud database or on your premises. You can choose the server dimensions on which the software runs and the database dimensions used. You can interface with the software application and data using URL connections (http:// and ftp://) and SOAP/WSDL software services. Special rates apply for this delivery model. If you choose our IaaS delivery model, an additional contract applies.

Main differences between IaaS, PaaS, and SaaS: With IaaS, you can choose hardware and software options. With PaaS, you can choose your database. With SaaS, you can't choose hardware, software, or database options. You just pay-per-use.
