The question arises …

The mystery of “The Cloud”...What does it mean 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• = Cloud computing – Utility computing

Infrastructure as a Service:

2 dimensions:

• Managed / Unmanaged Cloud• Deployment models: Private / Public Cloud

Infrastructure as a Service:

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

Infrastructure as a Service:

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

Local player

You can still trust your local hoster:

• You know him• You get support in your language• You can reach him• You know where your data is stored• You know what service levels you get

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)
