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 show-

back reporting or charge-back for both internal and external

functionality for each individual consumer

It Can’t Possibly Happen…

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

The Time is Now

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..

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?

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 self-

discovery 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.

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.

Step 1- Register Storage

Register Storage Wizard

• Currently- ZFS and NetApp Storage Supported

• Future- Exadata, OVM, VM….

Settings for Storage

• Setting up IaaS Storage

• Allocate amount of space required for DBaaS environment

Storage Registration Complete

Database Cloud

From the Middleware and Database

Cloud Home:

• Create PaaS Infrastracture Zone to

use IaaS

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.

Setting up the PaaS I Zone

Roles for PaaS

For the Izones, Roles are set up for user access, (SSA_User

Role)

Review of a PaaS Setup

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.

Self Service Portal Settings

Database Profile

Request Settings

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

DBA Controls Quotas

Quotas can be edited at any time and set to any

configuration.

Understanding DBaaS Roles

Storage Administrator Role

EM Storage Administrator, EM Storage Operator

Creating a Template- From an

Existing DB

Creating a Template – From a

DBCA Template or Snapshot

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

Custom Script Option

Run Custom scripts as part of templates

*This is also part of Schema as a Service

Use?

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.)

DBaaS in a Standard Environment

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.
