Software as a Service Def

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 designed to be scalable, customizable, and accessible from various 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 software 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. Which one suits you best, depends on your personal needs.

1. SaaS - Pay per use - Software as a Service is the most common delivery model. It means that you choose to work with the software via the standard secure (https) installation on the website domain, pay only peruse, and store your data in a shared database that is in the cloud. Normal user license rates apply for this. You can interface from and to the software application (CRM, collaboration tools, etc.) and data using URL connections (http:// and ftp://) and with SOAP/WSDL software services. If you choose our SaaS delivery model no other contract will apply other than the End-User License Agreement (EULA) that 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 common delivery model. It means that you choose to work with the software via a highly secured tunneled installation (VPN) on the website domain and store your data in a database that is in the cloud or on your premises. You can choose the dimensions and location of the database that is used. You can interface from and to the software application (CRM, collaboration tools, etc.) and data using URL connections (http:// and ftp://) and with SOAP/WSDL software services. Special rates for this delivery model apply. If you choose our PaaS delivery model, another contract will apply next to the End-User License Agreement (EULA) that is applicable when you pay for the user license and use the software. In that End User PaaS Delivery contract, the provider will agree on custom settings of the database and availability/backup delivery of your data.
3. IaaS - Choose your hardware and software dimensions - Infrastructure as a Service is the third common delivery model. It means that you choose to work with the software via a highly secured tunneled installation (VPN) on the website domain and store your data in a database that is in the cloud or on your premises. You can choose the dimensions of the server the software runs on and the dimensions of the database that is used. You can interface from and to the software application (CRM, collaboration tools, etc.) and data using URL connections (http:// and ftp://) and with SOAP/WSDL software services. Special rates for this delivery model apply. If you choose our IaaS delivery model, another contract will apply.

Main differences between IaaS, PaaS, and SaaS: With IaaS you get to choose hardware and software options. With PaaS, you get to choose database options. With SaaS you cannot choose hardware, software, or database options, you just pay-per-use.
