Alliance Data: Database Migration to Oracle CloudPresented by

Suresh TripathiDirector of IT

Who we are!You might not know our name, but you’ve seen what we do. Alliance Data is the engine

behind loyalty and marketing campaigns for more than 1,000 consumer-facing companies worldwide across all industries: retail, travel, pharmaceutical, financial services, auto, and

more.

That data-driven insight enables us to build dynamic and creative loyalty marketing programs and strengthen and deepen relationships between our clients and their

customers. In today’s changing-by-the-minute digital landscape, that’s more crucial than ever.

Challenges we had : Before Cloud Migration

Multiple data centers for Prod and Dev/QA env

Challenges with datacenter Vendor

Aging hardware

Sub-par DR environment but

always paying for it

High Cost Licensing Support

Slow provisioning

time

DB resources limitations

Patching support Single Oracle Home

Enterprise Applications

Exadata

Peoplesoft Financials

Peoplesoft HR

OBIEE

WebcenterAgilePLM

SOA

Hyperion

Before Migration to Oracle Cloud

Why Oracle Cloud: Why Now

Why not nowBig Oracle Footprint

Centralized Oracle database

dependency

Cost Benefits

Licensing Support

Lower Operational Cost

Existing relationship with

Oracle

Smaller migration Risk

Better DR architecture

Support future state architecture, roadmap

and Strategy

Oracle Cloud Solutions Options

Option 1 – (BYOL) to Exadata Cloud Service

Option 2 – (Non-BYOL) to Exadata Cloud Service

Option 3 – BYOL to 2-Node RAC

Option 4 – BYOL to Single Node Database

Option 5 – BYOL to Bare Metal Compute

What did we Pick and Why

WhatwePicked

Why

Option 2- (Non-BYOL) to Exadata Cloud Service

v Best available cloud offering for enterprise database

v Resources availability on Exadata solution

v Migration impact and efforts expected to be minimum

v Compatible with existing on-prem Exadata Databases

Setup on Oracle Cloud

Implementation : How we did it

Help from vendors (L&T Infotech and others)

Database: Migration to ExaCS X7

Peoplesoft: Lift & Shift

Hyperion: Upgrade & migration to OCI

OBIEE: Upgrade & migration to OCI

AgilePLM: Upgrade & migration to OCI

SOA: Upgrade & migration to OCI

Webcenter: Upgrade & migration to OCI

OCI: Oracle Cloud Infrastructure

Implementation : Lessons we LearntManual provisioning of database

DB Migration from on-premises to Cloud needs special attention

Careful design considerations for Oracle Multitenant

PDB cloning requirements

Container database only

Working with Encryption wallet needed a few iterations

Backup provisioning is manual

Implementation : Lessons we Learnt

Shared or individual Oracle Home

Get the latest DB image on Exadata

Oracle provided utilities Vs Customer utilities

Cloud tool upgrade for patching

Unparalleled Oracle support from their A-team and development team

Post Go-Live : Benefits

Separate Oracle homes

Higher capacity 5x memory2x Disc space3x cores Improved

Performance(30% to 50%

faster)

Simplified patching

Newer hardware CPU’s, Memory, Storage, IB, etc.

Significant Cost Reduction

• Consolidation• Cloud subscription

DBaaS parameter file and command

– simplifies creation

What we Plan to do Now and in Future

Available Built-in Feature Set

Real Application Testing: Database Replay

Data Masking and Data Encryption

Advanced Compression
