The document discusses reasons to use a private cloud over a public cloud. It notes that while public clouds provide scalability and cost benefits, private clouds allow for more control over data location and security. Specifically, a private cloud allows one to know exactly where data is stored and maintained, avoiding legal and security risks of public cloud data storage. The document concludes that private and public clouds each have advantages, and the best approach is often a hybrid model that combines the two.

Why consider a Private Cloud?
• It's so easy to put together a bunch of cloud services...
• An email account
• Online Office Environment (Google Docs)
• Group Collaboration
• CRM System (Salesforce)
• So why build an internal Cloud infrastructure?
• There are reasons to separate your data
• Privacy considerations
• Security requirements
• Or you need total control of location and structure of data

Benefits of Cloud Computing
• Billing is usage-based
• Scalability / rapid expansion of
infrastructure
• Virtualization of infrastructure
• Infrastructure consolidation
• Physical and application level
security
• Standardization of SaaS
applications

Benefits of Cloud Computing
• Billing is usage-based
• Scalability / rapid expansion of
infrastructure
• Virtualization of infrastructure
• Infrastructure consolidation
• Physical and application level

• Standardization of SaaS
applications
All these characteristics are true
for a Public Cloud.
While costs may be reduced
when you outsource to a
Public Cloud, all of these
characteristics are also true for
a Private Cloud!

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

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

Benefits of a Private Cloud (2)
• Imagine a disk from the Public Cloud being removed for
maintenance
• It may still contain some parts of your data
• In a private cloud environment that disk belongs to you
• In a Private Cloud you have a better control of the
connectivity
• You may have a direct WAN connection into your own cloud

Conclusion
• Private Cloud are NOT better than Public Clouds and
vice versa
• There are reasons, where a Private Cloud has its
benefits and sometimes may the better choice
• Especially data privacy and control concerns
• But the best is: you can mix and match Private and
Public Cloud solutions to form your own Hybrid Cloud
solution
