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
    • long-term 
  • safety and data protection
    • especially problematic when saving the data in a location not in Germany (when it's a German company)
    • is protection 
      • is  the cloud save?
    • risk save?
    • who has access?
    • where are the interfaces
  • risk  of renouncing own IT competence
  • reliability of the cloud
  • problems with the internet connection
    • reliability of the connection
    • not enough bandwidth at own or servers' location
  • potentially location
  • potential  need to adapt to the providers software if own software is not offered


    • Potentials
    • dynamic offered
    • data protection regulations can be violated
      • problematic when saving personal data in a location abroad (when it's a German company)

    Potentials
    • 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 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
