Design Considerations

• Build a Cloud with Oracle Solaris OpenStack

– Fully Supported, Enterprise Ready Software Stack

– Optimized for Oracle Database Workload

• Lock-Down the Cloud – Public Network Access Restricted to OpenStack Instances

– Separated Access to Infrastructure Components and Control Logic (The Undercloud)

• Virtualize the Workload. Virtualize the Control Logic

– Power the Infrastructure and the Workloads with Solaris Zones

Make it Secure and Easy to Maintain

Lessons Learned

• Start with a Clear Vision

• Establish a Team

– Project Sponsor, Customer (IT Dept & Users), Vendor and Partner

• Proof of Concept Matters

– Check what Really Works and Constantly Rethink and Rework Concepts

– Match Expectations, Requirements and Cloud Features

• The Road to Cloud is more than just Creating the Cloud Infrastructure

– Creating Images, Defining Flavors/Shapes, Software Deployment

– "Cloudifying" Internal Processes

• Engage and Convince the Prospective Users Early
