We are all excited about the cloud
The trick is knowing what your systems need,
and how the cloud can help.
Not everything has to or can live in the cloud
Only move to the cloud that which can benefit
The core strategy is ‘hybrid’
Take an À la carteapproach
We call this Software + Services

“THIS is where I want to spend my IT resources – I’m going to double down on this application!”
Only 2 reasons to use the cloud
Improve Bottom

Improve Strategery
Determine an ROI
Consider:- Current hosting costs- Current staff costs- Cooling/power/space- Migration costs- Licensing

When moving pieces to the cloud,
you need to leverage services.
Decompose your systems into pieces. This leads to flexibility.
How do things connect? Plan on service facades.

Consider a Service Bus
Design for scale.
It leads to *-ability.
Decouple. Decouple. Decouple.
Consider your data model.
