Title: Oracle Enterprise Manager DBaaS: Database, Schema, or
Terabytes of Data in Minutes

Description: Database as a service (DBaaS) is the latest trend in
providing automated database services to a wide set of end users. In this
session, you will learn about the latest features in DBaaS, including
schema-based consolidation, thin provisioning of data, and other exciting
features.

Private Cloud: PaaS vs IaaS
Increasing Enterprise value with Private PaaS

Private PaaS
• Enforces standardization and consolidation
• Provides Security and Compliance
• Maximizes component re-use
• Minimizes hand coding
• Maximizes flexibility and control


Three  The problem of many and varied
Key  Manual, time consuming provisioning
Challenges
 Data, lots of data!


Key Challenge 1: The
problem of many and varied

Solution: Standardization
and Consolidation


Need for Standardization and Consolidation
High Complex and ever growing
cost of database estate
operation
High cost of
deployment

Poor Service
Utilization
Delivery
H/W, CPU,
Storage
Workload
multiple skills,
lots of disparate Poor service, “a mixture of versions, operating systems,
systems, long lead
poor automation hardware; rapidly falling
times
into legacy”


Consolidation at PaaS and IaaS Layers
Consolidate onto standard, shared
and elastically scalable PaaS App App App

• Standardized PaaS for all applications
reduces heterogeneity, cost and complexity
PaaS • Accelerated new application development
App App App
• Cost savings from less hardware, power and
data center space
vs.
App App App • Software stack heterogeneity, cost and
complexity persists
• No administration (O&M) cost savings
Consolidate onto shared IaaS • Cost savings from less hardware, power and
without standardization IaaS data center space

Considerations for Choosing the Right Model

 Brownfield or Greenfield?
 Commodity Servers Vs Engineered Systems?
 Applications to be deployed, and their database footprint?
 Expected SLAs from business users?
 Isolation or Security requirements?
 Ease of management? Available skill set?
 Is self service needed? If yes, who is the user, and what do they expect from
this service?
Most Customers Settle On a Combination these Models


Comparison of DBaaS Cloud Models

Easy to Involved (based on
Maintenance Very complex (VM Sprawl) Easy
required resource isolation)

Low (Server and Storage High (Servers, storage, and Highest (Servers, Storage,
ROI Only) OS) OS, and DB)

Isolation Excellent Good Least

Implementation Difficult (standardize on DB

Application Some (excessive in many Home grown; requires app
All
Suitability cases) validation


Examples of DBaaS Cloud Model Usage

Resource Manager
• Security isolation through Data Vault
• Integrated with Database 12c Pluggable Databases
• Multiple pluggable databases within a single container
database


Schema as a Service User: Portal
• Out-of-box console ; no additional
set up required
– Supports custom background
• Rich service catalog:
- Database instances
- Schemas
• Database portal functions
– List all databases and
schemas
– List requests, quota usage,
and notifications
– Resource Monitoring
– Backup/restore
• RESTful Web Service based APIs
and CLIs


Schema as a Service User: Features
 A „Schema‟ request provides
– 1 Database (Application) Service
– N schemas/users
– 1 master account that has grants over other schemas
– 1 tablespace

 Request for a „Schema‟ instance
– Choose service templates with/without seed data
– Rename and set passwords for schemas

Key Challenge 3: Data, lots of
data!

Solution: Data Cloning using
Storage copy-on-write
technology and RMAN
backups


Data Cloning Overview

 Functional Testing of Applications
– Most functional tests require minimal data changes
– Testers frequently need to rollback data

 Most storage based solutions lack lifecycle management capabilities
– DBA Friendly. Clone „Databases‟ instead of „Storage Volumes‟
– Monitoring and configuration management of the cloned database
– Upstream Test Master creation workflows (integrated with Masking, Subsetting, etc)
– Monitor, implement quota and chargeback based on QoS


Data Cloning Options
Technology Comparison

Copy on Write RMAN Backup

• Oracle Database based
technology; Storage neutral
• Storage based technology
• Restore time proportional to
• Saves space and time
backup size
• Ideal for "use and throw“ i.e.
• Leverages existing
short lived databases
technology and infrastructure
• Storage Admin involved Data Cloning
• Completely managed by
DBAs

Assistant Vice President IT
Lead Database COE

About HDFC Bank
• Incorporated in August 1994
• India‟s second largest Private Bank with a nationwide network of
– Branches: 2,564
– ATMs: 10,000 (In 1,416 Indian towns and cities) & 20 million customers
– Debit Cards: 14.9 Million
– Credit Cards: 5.8 Million
• Industry: Retail & Corporate Banking
• Employees: 56,000
• Revenue: USD 5 Billion


Business Drivers
• Retail Assets Segment [Lending Business]
• 50% of HDFC Bank‟s Top Line
• Always under pressure to launch “New Schemes” to compete and
stay ahead in this segment
• IT must respond to this Business need because each new Scheme
means – changes to application and testing against Production data
[UAT database]
• Agility in launching new business initiatives

Life Before Database Cloud
• Average 3.5 days to provision UAT Database for Loan Management
Application
• Silo‟ed environment with Average 30% utilization
• Compliance requirement consume UAT testing resources.
• DBA activities mean $$ paid to SI for provisioning databases manually
• Overhead in managing configuration drift between production and test
environments.
• Rollout impact/delay on new business initiatives

Database Consolidation – Application Classification
• Classify application based on system availability requirement/criticality

System classification Application Classification

Tier 1 Top 15 in terms of systemic risk Customer facing mission critical systems

Tier 2 Top end & middle tier High visibility & enterprise wide usage

Tier 3 Bottom end of middle tier Smaller user base but critical business function
Surround Systems - Satellite system build around core
Tier 4 Low tier system

Database Consolidation Planning
• Identify candidate application for Cloud
• Further Group them based on availability requirement and sub
classification based on OS/DB

Cloud Zone Zone based on criticality Sub category based on version
Highly critical 11g zone
Exadata Zone
UAT system 11g zone (For pilot)
10 g zone
Highly Critical
AIX zone 11g zone
UAT system 11g zone (For pilot)
11g zone
Windows Medium critical
10g zone

Database Cloud Solution Architecture

Cloud Administration Setup
• Zones
 Exadata Zone
 AIX zone
• Role for each application on Exadata and AIX zone
• Quota is set based on existing infra available
 7 Databases on LOS Application
 5 Databases on LMS Application
 5 Databases on Web collection Application
• Universal charge plan
• Service Templates
 Exadata -Three templates with data
 Exadata -Three templates with only structure
 AIX template for Small, Medium, Large database only structure

Provision Databases using RMAN Backups
• Beta Customer for RMAN restoration integration feature with DBaaS
• Level 0 RMAN Backups of Production Databases from
Standby[Bunker Copies]
• Service Templates created for each of Level 0 Backups
• Process to Provision Databases through RMAN is same as Empty
Databases

Summary
 DBaaS supports three different DBaaS models
– Database in a dedicated VM
– Databases in a shared cluster or installation, and
– Schemas in a shared database
 Special focus on data cloning
– Storage copy-on-write technology, and
– RMAN backups
 Out of box portal to deliver all types of services


DBaaS is the Sweet Spot for Enterprise Clouds
Benefits All Stakeholders
