Hybrid is the Answer For Challenging Global Infrastructure Needs
 Agile infrastructure roll out (to meet time to market)
• Stage 1 – Leverage public cloud
• Stage 2 – Private cloud (One AZ) + Public cloud (Secondary AZ)
• Stage 3 – Private Cloud (multiple AZ) + Public Cloud (Cloud bursting)
High utilization rate of private cloud
• Option to cloud burst into public cloud
Predictable investment
• Gradual roll out available zones
• Study the peak load and move the load into private
cloud
Leverage public cloud services
• Private cloud does not have all features of public cloud
- Example email, messageQ
• Use public cloud as DR backup for non-sensitive data

It starts with Latency and Bandwidth! Then other things become
important…
WHY THIS WORKS WELL
Key: pick a datacenter near enough a public cloud network so
that…
• Latency is similar from private-to-public as it is from public-to-public
• Be someplace where bandwidth is cheap
Ensure no lock-in of customer codes
• Change public providers based on geography, pricing, …
Use a private cloud stack that is pervasive
• OpenStack is arguably the winner of the stack wars
Pick a good hybrid partner
• We did 

LESSONS LEARNED
 Without tools, hybrid is very complex to deploy and operate
• Due to lack of management tools and inconsistent APIs
• Management tools like RightScale are essential to deploy and operate Hybrid Cloud
 OpenStack is highly flexible and configurable, but also complex and fraught with
choices
• Either invest in your own development effort, or work with an integration partner
• Converting an open source project to an “opinionated” distribution
Longer cycle to upgrade
• API changes
• Mostly a problem for us early adopters (who were tempted/forced to pave over gaps)
