SaaS
SaaS in cloud computing
Software as a service is one of the most common models of cloud service, along with infrastructure as a service (IaaS) and platform as a service (PaaS), and SaaS combines the three services into one, which is infrastructure, operating system, and an operating environment in addition to installing the program or application all of them on the cloud, and all the user has to do is enter a browser The web and start working on or the software without the need to install it on its own device (infrastructure) or taking into account the availability of an operating environment for the program or application.
A simple example of SaaS: Google Cloud Docs, from anywhere and any device, regardless of the operating system on your device or whether the program has been installed on your device, all you have to do is head to the Google website and access Google Docs and work on it directly.
This common example applies to similar services that you may have used before without realizing that it is SaaS
What applications are available on SaaS
Service providers offer a variety of cloud applications, especially in the field of business, to facilitate the business of companies and individuals, such as email service, customer relationship management, billing and salary statement, sales management, financial management, human resources management, data center management, document editing and sharing, and others.
Software as a service price
The price of the SaaS cloud service, like other cloud services, is determined based on quotations from which you choose what suits you: monthly or annually. In addition, there are criteria that service providers follow in pricing SaaS products according to several things, such as: the number of application users, or the number of transactions on the application, or any other metrics desired by the service provider.
SaaS Pros
- Reducing the costs involved in establishing, operating, and maintaining the infrastructure
- Ease and flexibility in accessing applications from anywhere and from any device, regardless of its resource capabilities
- Application service fees are lower than the fees for traditional software licenses at times, and the use of SaaS is feasible especially when you need to use a specific program once a year, for example, then there is no need to purchase software licenses that you only need once a year
- The use of SaaS is financially feasible, especially for programs and applications that need a specialized infrastructure. Instead of the company buying this equipment to support the programs, all it has to do is subscribe to the cloud service that provides the application and use it regardless of the infrastructure available to it.
