Each and every user facilitates the single use case. A main growth is possible within business and maintenance of compliance. (Source: Carlin & Curran, 2013)
Advantages of AWS Cloud Environment The main advantages of AWS cloud environment are as follows: Easier usages due to lack of complexity. There is absolutely no limit for capacity in the AWS cloud infrastructure and hence client can easily use this for their own purpose (Carlin & Curran, 2013). AWS infrastructure is extremely reliable and there is almost zero issue for data loss.

Issues of Office Automation The main issues of office automation are as follows: Extremely costly. The entire procedure to implement Office 365 is extremely lengthy. Lacking of access control. Adjusting is quite difficult for office automation process. (Source:Xiao, Song & Chen, 2013)
Differences between IaaS, PaaS and SaaS The main differences are as follows: IaaS: It provides better implementation of several networkingservices,computingservicesand storage services (Xiao, Song & Chen, 2013). PaaS: It operates at lower level in comparison to any other models and a virtualized platform can be provided. SaaS:Thismodelprovidesservicesathighlevel and hence services were easy.
Recommended Cloud Model for DTGOV A recommended cloud model for the organization of DTGOV is infrastructure as a service or IaaS. IaaS can be appropriate for their SharePoint 2010 service.
