Hi – I’m Steve
OaaS – Operations as a Service www.ChinaNetCloud.com
Welcome to the cloud !
OaaS – Operations as a Service www.ChinaNetCloud.com
This is great, I think
OaaS – Operations as a Service www.ChinaNetCloud.com
This is great, I think
OaaS – Operations as a Service www.ChinaNetCloud.com
My goal is to tell you what I think
OaaS – Operations as a Service www.ChinaNetCloud.com
Clouds are great
OaaS – Operations as a Service www.ChinaNetCloud.com
Clouds are great – but can get you in trouble
OaaS – Operations as a Service www.ChinaNetCloud.com
Clouds are actually more difficult/complex than you think
OaaS – Operations as a Service www.ChinaNetCloud.com
So let’s get started talking about clouds
OaaS – Operations as a Service www.ChinaNetCloud.com
What is the cloud ?
OaaS – Operations as a Service www.ChinaNetCloud.com
We are talking about IaaS / Infrastructure
OaaS – Operations as a Service www.ChinaNetCloud.com
This is about how you Design, Build & Deploy on IaaS
OaaS – Operations as a Service www.ChinaNetCloud.com
Why the cloud ?
OaaS – Operations as a Service www.ChinaNetCloud.com
Cheap !
OaaS – Operations as a Service www.ChinaNetCloud.com
No up-front capital – Pay as you go
OaaS – Operations as a Service www.ChinaNetCloud.com
Easy to start – Click and compute !
OaaS – Operations as a Service www.ChinaNetCloud.com
All true, but . . .
OaaS – Operations as a Service www.ChinaNetCloud.com
Not that important
OaaS – Operations as a Service www.ChinaNetCloud.com
It’s important to accountants – that’s not us
OaaS – Operations as a Service www.ChinaNetCloud.com
So what is important – to US ?

Cloud Design – Think Layers
OaaS – Operations as a Service www.ChinaNetCloud.com
A key opportunity is Service Architectures – Separate functions
