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

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.
