3. What is DBaaS?
Database as a Service (DBaaS) is an architectural and
operational approach enabling DBAs to deliver database
functionality as a service to internal and/or external customers.
Database as a Service architectures support the following
required capabilities:
 Customer side provisioning and management of database
instances using on-demand, self-service mechanisms
 Automation of monitoring with provider-defined service
definitions, attributes and quality SLAs
 Fine-grained metering of database usage enabling showback reporting or charge-back for both internal and external
functionality for each individual consumer

5. Why DBaaS?
DBaaS standardizes and optimizes the platform requirements
which eliminates the need to deploy, manage and support
dedicated database hardware and software for each project’s
multiple development, testing, production, and failover
environments.
DBaaS architectures are inherently designed for elasticity and
resource pooling. They deliver production and non-production
database services that support average daily workload
requirements and are not impacted by:
 Resource Limitations
 Time Sensitive Projects
 Hardware limitations/budgets

6. The Time is Now

7. Embracing DBaaS as a DBA
The Great DBA…
 Automates everything
 Desires new learning opportunities
 Desires a secure, controlled setup for a self-service portal
 Approaches challenges and answers with simple, robust
options to answer.
DBaaS OFFERS THIS..

8. Services Options in DBaaS

9. Summary of Moving Parts
 How much do you already use in
your everyday DBA work
 How can this be used to create a
new and better way to automate
resource allocation so the DBA
can do more with less?

10. DBCA Template
 DBCA= Database Configuration Assistant

11. How DBCA Fits in the Equation

14. Setting up DBaaS
 The Cloud Administrator will
 Define roles and users in the Self
Service Portal.
 Installing the agent to manage all
“unmanaged hosts” so selfdiscovery of any DBaaS
environments that are created.
 Set quotas, privileges.
 Software library will allow
automation.
 Provisioning will set who will be
granted and how much allocated to
each customer, administrator
and/or business unit.

15. Self Service Portal Design
 Oracle Home is utilized by
one or multiple service
templates.
 Templates serve DBaaS
options to Self Service
Portal for customers.
 Role is designated to “Self
Service Administrator” but
often DBA.

16. EM12c- Enterprise Menu

17. EM12c- Setup Menu

18. Step 1- Register Storage

19. Register Storage Wizard
• Currently- ZFS and NetApp Storage Supported
• Future- Exadata, OVM, VM….

20. Settings for Storage
• Setting up IaaS Storage
• Allocate amount of space required for DBaaS environment

21. Storage Registration Complete

22. Database Cloud
From the Middleware and Database
Cloud Home:
• Create PaaS Infrastracture Zone to
use IaaS

23. Setting up PaaS
• Set up PaaS for Development, Test, etc.
• Keep it simple- simple designs are easier to manage.
• Solid chargeback designs will ensure that simplicity in
PaaS design is effective for business.

24. Setting up the PaaS I Zone

25. Roles for PaaS
For the Izones, Roles are set up for user access, (SSA_User
Role)

26. Review of a PaaS Setup

27. Setting up Pools and Profiles
In the Setup Menu
Database Pools contains a set of
resources that can be used to provision a
database instance within a PaaS
Profiles are information collected from a
database to set up the database part of a
service template.

28. Self Service Portal Settings

29. Database Profile

30. Request Settings

31. Quotas for Requestor
Quotas dictates how many resources overall a user of the Self
Service Portal has.
Allocated by Role and assigned to user• Memory
• Storage
• CPU
• How many Databases at a given time
• How many schemas

32. DBA Controls Quotas
Quotas can be edited at any time and set to any
configuration.

33. Understanding DBaaS Roles
 Storage Roles
 View Any, Register, View, Manage Any and Full
 Target Privileges
 Snap clone, Full
 Storage Administrator Role
 EM Storage Administrator, EM Storage Operator

34. Profiles in Place

35. Creating a Template- From an
Existing DB

36. Creating a Template – From a
DBCA Template or Snapshot

37. Control of Template Resources
 Set Parameters
 Turn on Auditing
 Configure values for memory, recovery and Undo
 Decide if the SSA Admin has ability to edit values

38. Custom Script Option
Run Custom scripts as part of templates
*This is also part of Schema as a Service

39. What PaaS Will Your Template
Use?

40. What Roles have Privileges to the
Template?

41. Review Your New Template

42. To Request

43. Self Service Portal

44. Fulfilling Request Info

45. Portal Post Request

46. A Mature DBaaS Catalog
 Catalogs offer external customers options to choose from.
 Services are really just service templates, (discussed later)
 Note that these each [most likely] share resources, (i.e. same
underlying machines virtually allocated.)

47. DBaaS in a Standard Environment

48. The Future
 Purchase multiple Exadata machines, using OVM , (may
change to Nimbula product since acquisition) create large
VM hosts to private clouds with DBaaS.
 Using VMs from third party vendors, create large, private
clouds for use with DBaaS.
 Simplify Development, Test, QA requests for database
refreshes, new environments
 Simplify cloning procedures for any environment
 Supply afterhours support and maintenance automation.

49. Thank you!
