One important aspect of cloud computing is Availability; all Oracle solutions are built with availability in mind and Oracle provides a blueprint called the Maximum Availability Architecture and in this session we will look at the important aspects of this architecture and how you can achieve Continuous Availability for your private database cloud that extended to included non-oracle databases as well. From this presentation you will learn about: • The importance of Continuous Availability • The Causes & Impact of Downtime • Road map to building a flexible Maximum Availability Architecture • Extending continuous availability to your non-Oracle databases

Typical Challenges with Disaster Recovery (DR) Deployment
Risk(*)
• Data inconsistency or
corruption
• Business exposure to lost
critical transactions
• Company reputation at
stake
Cost
• High investment in
Hardware and Software
• DR site operational aspects
• Lack of clear ROI (unless a
disaster occurs)
Complexity
• Planning & Deployment of
the DR site
• Primary / DR
synchronisation
• On-Demand elasticity after
migration to the DR site
