02 Personalisation Server. Why?

7 Telefonica PDI

Personalisation Server. Why?

•  We were storing profile data of millions of customers. However…

01

8 Telefonica PDI



§  Each service had its own internal storage

§  Customers profile was scattered across a variety of different DBs

§  In some cases stored in a DWH, others in isolated DBs

§  No homogeneous interfaces or data structure

§  Repeated or out-dated information

01

9 Telefonica PDI



Customers data was neither shared nor usable

Personalisation Server. Why? 01

11 Telefonica PDI


•  Personalisation Server as master customer’s data storage

§  Operational storage, real-time access

§  Flexible customer’s profile structure, classified in services

§  Data sharing across all services

§  Massive off-line batch interface

§  Authentication and fine grained authorization

§  Fault tolerance and high availability

§  Inexpensive solution, low hardware requirements

01


03 Oracle-based solution

13 Telefonica PDI

Oracle-based solution

•  20 people involved (7 developers) in 14 – 15 months

•  Oracle 11g Standard or Enterprise

•  Three instances deployed

•  Three iterations, focusing on performance enhancements

01

14 Telefonica PDI

After three iterations

•  Three successful deployments, but…

§  Oversized storage requirements

§  Performance below expectations

Still not scaling enough

04

15 Telefonica PDI

The fourth deployment arrived

•  Everything went fine until one month before deploying

•  New performance requirements appeared §  40% more data to be stored and processed

§  Reload the whole DWH (22M customers) daily in small time window

•  Servers already purchased

01

16 Telefonica PDI

Huge improvement needed

•  Reduce storage to a half

•  Enhance performance up to 3 times

•  Only 4 months with a reduced team

Fourth iteration with Oracle or move to a new technology?
