c) Risks and potentials that cloud computing might imply (for IT in general)

Risks
  • dependent on the provider
    • provider could go broke
    • service could be bad
    • always afected affected  when provider has to shut down due to e.g. an update 
    • long-term access to important data is reliant on the provider
  • safety and data protection 
    • is the cloud save?
    • who has access?
    • where are the interfaces
    • risk of loosing corporate secrets 
    • abuse of personal data
  • risk of renouncing own IT competence
  • reliability of the cloud
    • risk of loosing important corporate data
  • problems with the data
  • a working  internet connection
    • reliability connection is crutial
      • reliability  of the connection
      • not enough bandwidth at own or servers' location
    • potential need to adapt to the providers software if own software is not offered
    • data protection regulations can be violated
      • problematic when saving personal data in a location abroad (when it's a German company) 
      • risk of fees due to compliance violations

    Potentials
    • dynamic violations

    • Potentials
    • scalable
    • dynamic  load distribution - on demand
      • not all IT resources have to be bought, only those that are needed
      • 10% -50% of the IT hardware is only used in load peaks
      • quick renting of additional capacity i needed (e.g. due to business growth)
    •  lower costs
      • no investment in own assets
      • providers have IT for many companies -> due to amount of resources individual services are cheaper than buying the IT on their own
    • no investment risks (for small companies)
      • business models can be testes and quickly enter and exit the market - short time to market
      • IT resources can just be cancelled and do not have to be sold again
    • management again
  • easy: management  of the servers is outsourced
    • no need of in-house experts (expensive)
    • not dependand on own IT employees
  • Green IT
    • servers are only utilized when needed -> the power consumption is lower 
  • no long-term capital tie-up
    • needed service and hardware are rented as needed
  • risk transfer to provider through defining a SLA (Service Level Agreement)
  • technology is up to date
    • minimizing the risk of default
    • faster and more save
  • using regional locations that are cheaper than storing the IT in the location of the own company
