The questionarises …
The mystery of “The Cloud”...
What does itmean to you?

What is “The Cloud” exactly?
The Cloud describes a (business) model :
Based on the Internet
Provided ‘as a service’
Which involves dynamically scalable resources
Which is flexible in all it’s aspects

Service layers
Most common service layers:
Software as a Service (SaaS)
Platform as a Service (PaaS)
Infrastructure as a Service (IaaS)

Software as a Service: SaaS
Software as a Service (SaaS)
Example: Salesforce.com
Applications hosted online
No need for software (typically browser based)

Platform as a Service: PaaS
Platform as a Service: Paas
Example: Google Webengine
Facilitates deployment of applications
Services available on the internet

Infrastructure as a Service: IaaS
Infrastructure as a Service (IaaS)
Example: Combell Public Cloud

Infrastructure as a Service:
2dimensions:
Managed / Unmanaged Cloud
Deployment models: Private / Public Cloud

Unmanaged Clouds:
Examples: Amazon, Azure
Virtual Colocation
Full control using control panel
Managed Clouds:
Example: Combell Cloud
Everything up until the OS is managed
SLA’s on the whole solution

Well-known deployment models:
Private(Dedicated) Cloud
Public(Shared) Cloud
Hybrid Cloud

Private Cloud
Privately owned (dedicated) hardware
Tailor-made solutions
Optimal performance isolation
Ideal for larger environments

Public Cloud
Shared Farm
Optimal Resource distribution
Pay as you grow
No upfront investment

Localplayer
You can still trust your local hoster:
You know him
You get support in your language
Youcanreachhim
Youknowwhereyour data is stored
Youknowwhat service levelsyouget

Conclusion
Planning to use an unmanaged Cloud solution?
BEWARE:
You’ll have to invest in knowledge
You’ll need to recruit people to manage it for you
You’re sourcing back in (vs outsourcing)
