  9. 9. Reasons to use a Private Cloud 9 The main difference between Private and Public • With a Public Cloud you have elasticity built-in • Your Cloud Service Provider has all the ressources and you can scale on-demand • With a Private Cloud you scale through physical provisioning • This is done by either your Cloud Service Provider or your internal IT-Department adding more hardware ressources • Or you can expand further into a Public Cloud

  11. 11. Reasons to use a Private Cloud 11 Benefits of a Private Cloud • In a Public Cloud you cannot put your finger on a cluster, a single server or a disk where your data is actually located • For a lot of applications, this might not be a problem • But if you handle personal information and data, for which the handling is regulated by your country (BDSG) or in your industry (banking, insurance)... • Your are at risk (best) • You violate security or privacy laws (worst) • In a Private Cloud you do know where your data is

  15. 15.
