The document explains Database as a Service (DBaaS) as a cloud-based solution offering scalable, secure, and on-demand database management, contrasting it with traditional database architectures. It highlights two options for implementing DBaaS: virtualization and grid infrastructure/multitenant databases, emphasizing the need for optimization, cost efficiency, and automation. In conclusion, DBaaS improves efficiency by consolidating resources and enhancing scalability and performance across applications.

- 4. What is Database as a Service? DBaaS is a Cloud base approach to manage databases, the database functionality is delivered as a service to one or more consumers, masking all complexities. A successful implementation has to satisfy the following characteristics: Flexible, scalable, secure and on-demand platform, oriented to the self-service. Consolidated database environment with mutualized HW & SW resources . The Platform Governance among other functionalities includes: Lifecycle management, Capacity Planning and Capacity Management. Industrialization and automation of the repeatable tasks. Optimized Time-to-market. Cost Efficiency. #SDF16

- 13. DBaaS on Virtualized Environment Pros Cons Standard architecture for all SW components. Licensing restrictions with Oracle products. Native scalability, flexibility and high availability. I/O performance degradation for high demanding databases. Rapid VM provisioning operations. Increased troubleshooting complexity. Suitable to industrialization and automation. DBAs delegate to System Admins critical database tasks: resource management, high availability, scalability and capacity planning. #SDF16
- 14. DBaaS Option 2 Grid Infrastructure & Multitenant Database #SDF16
- 15. Grid Infrastructure Overview Oracle offers great native features to build a DBaaS platform: Grid Infrastructure: ASM & CRS provide solid storage and clustering foundation to the database infrastructure at no-additional-cost. RAC & RAC One Node: introduce high availability, scalability and operation flexibility. Resource Manager and Instance Caging: guarantee capped resource consumption, and performance stability. Quality of Service: real time performance analysis, prioritizing the most strategic services and assuring predictable performance for consolidated applications. Multitenant: designed for high consolidation density and cloud environments. #SDF16

- 24. DBaaS Takeaway From the provisioning phase to the decommissioning one, the DBaaS offers great advantages: The consolidated platform permits all applications benefitting of the same features, reducing time-to-market and increasing efficiency, performance and availability. No waste of resources avoiding fragmentation and low level of utilization. Great vertical and horizontal scalability. Ideal setup to enforce standardization, industrialization, security and automation. The DBaaS platform offers “engineered & built once, use many”. Pay-as-you-Grow Architecture. #SDF16
