Database as a Service (DBaaS) delivers database functionality as an on-demand cloud service, masking complexity. It offers flexible, scalable, secure databases with self-service provisioning and consolidated resources. DBaaS provides advantages over traditional databases like lower costs, faster provisioning, and increased efficiency through standardization and automation. DBaaS can be implemented through virtualization or using Oracle's Grid Infrastructure and multitenant database features which provide high availability, scalability, and performance isolation through resource management. DBaaS offers a standardized platform that can be engineered once and used for multiple applications in a pay-as-you-grow model.

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.

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.

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.

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.
