Cloud Computing

Introduction:

In this week we are discussing about which cloud service model we are going to use for the organization. Assuming that the users of the software include both the home users and business users, we are considering the SaaS service model as our cloud service.

Software as a Service (SaaS) Model:

Before deciding the type of service model, company should consider the usage of the software by different users. Assuming that the users use the software once in year and business users may use four times in a year, we are considering SaaS model. Some of the core benefits to consider SaaS are:

· Compatibility where all the users have same version of software

· Global Accessibility

· Patch management and automatic updates

· Ready to use

In this model the users can use the cloud service based on their usage. This will help the organization to reduce the cost in developing and maintaining its servers, operating systems, storage or data storage.

In this service model users can use the application using different web services. Users can use the both application and configure the application based on their usage. For business users SaaS platforms like salesforce.com can be considered as it helps to avoid development of additional programming for the business users. This helps the users to use the application without installing any additional software. Even if the devices are not working the data will be secured.

While using this service the user should mention if there are multiple users or the user alone use the service. By providing the number of users details the components like data storage, business components etc., can be shared with mentioned multiple users. The users need not to worry about the installation of software as the SaaS providers will take care of it.

The SaaS applications having salesforce.com include Google Docs for document sharing, Web e-mail systems like Gmail, Yahoo and Hot mail. This model is useful for the small scale industries who have very less budget and during collaborating with multiple projects can use SaaS platform.
