Enterprise architecture and the cloud

Planning for blue skies

A solid enterprise architecture foundation begins with understanding the possibilities 

We’ve heard the stories—when moving to the cloud felt more like a wave of thunderstorms rather than blue skies.  It started out fine with a clear business case to move to the cloud for all the usual reasons—scalability, cost efficiency, and performance—but there was one problem after another during the migration.  What went wrong?

The cloud was the right decision, but without the architect to mitigate the risks of interoperability, security gaps, application failures, and unplanned costs, even experienced builders will quickly run into problems. 

To develop the blueprint, the architect gains a deep understanding of your goals for performance, security, resilience, disaster recovery, and governance. Each application is assessed based on the goals and specific criteria to determine next steps.   This builds the foundation for the architecture decisions including cloud operating models and vendor options.

Application assessment model


Review function, need, cost


Assess for architecture, capabilities, standards, patterns

Hosting model

Identify viability based on function to security

Operating cost

Determine impact on annual operating cost

Migration cost

Determine effort and risk to plan, design, build, test, migrate

Next steps: Retain, retire, rehost, replatform, refactor, replace
