The two Role Models – Cloud Service Vendor and Enterprise 
Cloud Service Buyer  
View of the Cloud Service Vendor 
According to Accenture many top executive of Cloud service providers say 
that it is one of the most difficult challenges to cope with the complexity 
associated with setting up a Cloud service offering.

New Cloud service providers have successfully positioned in the Cloud 
services market, such as the Seattle‐based online retailer Amazon who is 
today one of the worldwide leaders of Cloud services. According to IDC, 
Amazon Web services (AWS) will exceed sales of $1 billion per year in 2012. 
Also well‐known is Salesforce.com with a CRM‐solution from the Cloud for 
Enterprise customers. In addition to the broad availability of Public Cloud 
services, currently private Cloud services for enterprise customers are made 
available. It can be expected that the portfolio of Cloud services for 
enterprise customers will be covering a growing range of business areas. 
View of the Enterprise Cloud Service Buyer 
On the Cloud service buyer side, enterprise customers are equally 
challenged when it comes to the systematic use of Cloud computing and 
Cloud services. On the benefit side, the use of Anything‐as‐a‐Service (XaaS) 
promises cost efficiency, scalability, and increased agility to highlight only 
some of the benefits. In IDC’s (2009) survey conducted with IT executives 
and chief information officers (CIO) across Asia/Pacific (excluding Japan), 
they found that 41% of respondents are either evaluating Cloud solutions 
for use in their businesses or already piloting Cloud solutions. On the other 
hand, IDC also reported that nearly 60% of European chief information 
officers are already using Cloud services—even if they do not realise it. 
Cloud computing changes the pricing of IT services
52
and can be used as a 
response to the changes in the business environment to a tighter cost 
management since the financial crisis in 2008. Enterprise customers do not 
want to bind themselves to fixed IT costs. Enterprise customers want to 
transform capital expenditures (CAPEX) into operational expenditures 
(
OPEX) in IT. That is why “Pay per Use Pricing” used for Cloud services has 
gained a lot of interest among customers.
