server is under the project's control from the BIOS up, and is sufficient for 
the requirements of the initial phase. 
In the second phase, where it becomes apparent that this customer service 
is being more heavily utilised than estimated, it will be useful to take action 
to ensure better scalability and availability. For this reason, phase II of the 
project envisages optimizing the project for PaaS. Phase II comprises a 
redesign of the web application, accommodation for Microsoft SQL Azure 
and the use of Microsoft Azure as a PaaS. This removes the need to maintain 
the serverOperating Systems, the webserver, the database and complex 
backups, etc., as in phase I of the project. If the web application turns out to 
be interesting for third parties, phase III of the project envisages adding 
multi‐tenant capabilities to the application, with separate user 
management, etc. The plan for phase III is to offer the software for use by 
customers, and thus providing it as SaaS.

Cloud Service commonly used today 
Smartphone and Tablet users are consuming a vast range of Cloud services, 
without even realising it. Some of these services are mandatory to the 
operation of these devices e.g. Appstores, update services, etc.  Several 
other services are either convenient or are supporting the business process. 
We will look into the service supporting the business process here.  
Storage Clouds (Storage as a Service) 
There are a variety of services in the Cloud offering storage space, most of 
them have a free of charge entry‐level. These services are typically 
end‐user‐oriented and often allow users to store only specific data types. 
The most popular examples of end‐user oriented offerings are DropBox, 
SugarSync, Google Drive, etc.  There are also products of this kind which are 
more focused on businesses, where security, access control, access groups, 
reporting and storage location are the main focus. Examples of these 
offerings are Citrix Sharefile, Microsoft SkyDrive, Wuala, etc.  In addition to 
the pure gigabytes of storage these services can offer online editing, printing 
or preview functions. 
Other services can be viewed more as outsourced backup solutions; again 
there are many options for end users, and a number in the enterprise 
sector. It is interesting to see that the acceptance of this kind of solution is 
greater in large corporations than in small to mid‐sized businesses. This is 
mainly attributed to the fact that large corporations structure and
