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

Risks

Potentials

dynamic general)

Risks
- dependent on the provider
  - provider could go broke
  - service could be bad
  - long-term
- safety and data protection
  - especially problem when saving the data in a location not in Germany (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
