Expertouch Technologies is a SAAS development company. Software as a service is typically described as a method of delivering apps to users over the Internet without the requirement for the user to install, maintain and develop the software and associated infrastructure. SaaS is one of three main categories of cloud computing, alongside infrastructure as a service (IaaS) and platform as a service (PaaS).SaaS removes the need for organizations to install and run applications on their own computers or in their own data centers. This eliminates the expense of hardware acquisition, provisioning, and maintenance, as well as software licensing, installation and support.
