may  or  may  not  be  able  to  increase  the  service  volume  (be  it  servers,

               accounts,  or  whatever)  when  that  need  arises.  Some  providers  have
               facilities to hedge this risk. For a fee, the customer can make reservations of
               capacity. Generally, without financial commitment from the customer, there
               is not likely to be much commitment from the provider.
                  From the viewpoint of a financial controller or chief financial officer, the
               move from internal IT to public cloud computing represents a reduction of
               capital on the balance sheet. This might take a while to play out because
               assets depreciate over the years. Depending on the financial situation of the

               organization, this reduction of capital may be a good thing.








               Capital expenditure (CAPEX) reduction and the increase in operating

               expenses  (OPEX)  are  sure  to  show  up  somehow  on  the  exam.  The
               reduction  in  CAPEX  on  IT  services  allows  a  business  to  either  save
               money up front or use that capital to benefit the business in other ways.
               Bear in mind that the benefit of migrating CAPEX to OPEX might not

               be realized immediately.



                  With cloud computing, there is an increased volatility in the cost base.
               Costs will go up and down more often and more rapidly. This puts greater
               demand on financial management capabilities.



                CERTIFICATION OBJECTIVE 6.03



               Understand How to Maintain Strategic Flexibility


               From the perspective of the cloud customer, there are clear and present risks
               such as a provider going out of business or being unavailable across the
               network.  You  must  have  a  contingency  plan  to  deal  with  these  potential
               incidents.



               Exit Strategy
               One of the fundamental risks in cloud computing is that the vendor either
               goes out of business (that is, goes bankrupt) or decides to no longer serve
               the customer well enough. Although this situation is also well known in the
