“Using the scalability features built into Microsoft SQL

Server 2008 R2, Corillian Online can easily support up

to five years of transactional data for one of the top-10banks in the United States.”

-Mike Lader, Product Development Director, Fiserv

Faced with growing demands for a seamless, contextual online

banking experience, one of the top-ten banks in the United

States wanted to provide online banking users with the ability to

access and analyze long-term transactional data. The bank

worked with Microsoft Partner Fiserv to ensure that the Fiserv

online banking and Personal Money Manager (PMM) solution

had the scalability and performance to meet the bank’s mission

critical workloads. Now, the bank can address these

requirements and drive customer satisfaction by integrating in-

demand information into the connected digital lifestyles of its

customers.



SituationFiserv, a Microsoft Partner based in

Brookfield, Wisconsin, is a leading provider

of information management and e-

commerce solutions for the financial

services industry. The company has more

than 16,000 clients worldwide and its

solutions are currently being used by some

of the financial industry’s largest banks.

A leading provider of online banking

solutions for the last 15 years, Fiserv offers

a suite of online banking solutions,

including the flagship Corillian Online, a

licensed product for medium and large

institutions that is typically deployed on-

premises in the bank’s environment.

Corillian Online integrates online banking,

payments, and personal financial

management tools into a single user

interface.

As a result, bank customers can access all

their financial transaction details—such as

money transfers, bill payments, andpending transactions—from one page. The

product features the optional Personal

Money Manager (PMM) tool, which gives

users instant, easy access to a

comprehensive history of transactional

data, organized into meta-views and micro-

views of their spending behaviors. PMM

helps banks improve customer satisfaction

by providing them with accessible insight

into their everyday financial lives.

A Fiserv customer—one of the top-ten

largest banks in the United States—wantedto make additional transactional data

available to their customers via their PMM

solution. The delivery of this type of value-

added capacity enables a bank to

differentiate itself and improve customer

satisfaction.

Specifically, the bank was interested in

giving users the ability to access and

analyze several years of transactional data.

Mike Lader, Product Development Director,

Fiserv, says, “Typically, banks in their peer

set have between 60 and 90 days of

transaction history in their systems. But this

particular bank wanted to provide their

customers with the ability to perform year-

to-year analysis of transaction data. The

bank’s objective was to support up to five

years of transaction history.”

In addition to improving the scalability of

their PMM capabilities, the bank also

sought to improve the performance of its

online banking solution to achieve the best

customer experience possible. “The bank

wanted the ability to handle years of

records, but it didn’t want system

performance—or its customers—to be

affected,” says Lader.

SolutionFiserv demonstrated Corillian Online in a

laboratory test so the bank could evaluate

the solution’s scalability and performance.The solution is based on the Microsoft .NET

Framework 3.5 and developed using the

Microsoft Visual Studio Ultimate

development system. It runs on Microsoft

SQL Server 2008 R2 software and the

Windows Server 2008 R2 Enterprise

operating system.

During a three-week period at a Microsoft

Technology Center, Fiserv and the bank

conducted performance and scalability

tests of Corillian Online. The bank asked

Fiserv to design a system that could storemore than 65 terabytes of transaction data

in a distributed system, so customers could

access multiple years of history from the

first day of enrollment online. “Scalability

was key for the bank—it needed proof that

Corillian Online could handle large

amounts of data,” says Lader.



Approximately 13 million virtual online

banking users and 47 million accounts were

created for the tests, which were conducted

on 12 web servers, 12 application servers, a

relationship manager server, and two

database server clusters. This configuration

was set up to replicate the bank’s online

banking application infrastructure. “Because

of the amount of data the bank wanted to

store, we prepopulated the PMM databases

with up to five years of transaction history,”

says Lader.

During tests, Fiserv wanted to see how the

system would cope with the loading of

millions of data records. “We needed to

establish how online users would be

affected,” says Lader. Fiserv tested a PMM

transaction load of more than 155 million

records, with 3,000 virtual users, which

simulated a much larger number of

concurrent users. Lader says: “We wanted

to simulate the experience a substantial

amount of users performing transactions at

the same time, to see what performancewould be like.”

BenefitsUsing Corillian Online and PMM, the bank

can now provide its online customers with

a transaction history of up to five years, an

often requested capability which helps

improve customer satisfaction. And with

increased scalability and performance, the

bank can store large amounts of data and

deliver it to customers quickly, which sets

the bank apart from the competition.

Increases Customer Satisfaction

“Using the scalability features built into

Microsoft SQL Server 2008 R2, Corillian

Online can easily support up to five years of

transactional data for one of the top-ten

banks in the United States” says Lader.

“Now, if the bank’s customers sign up for

online banking, that transaction history will

be readily accessible to them. Customers

will not have to wait for this information to

populate over time, because the data is

already stored. That’s a significant point of

differentiation in a very competitive

market.”

Improves Performance

The Corillian Online tests also

demonstrated that system performance is

not affected even when banking

transactions run simultaneously. “We

originally thought the solution would be

able to process 500,000 records a minute,

but the tests showed 1.37 million records a

minute,” says Lader. In addition,

performances of key dashboards, such as

checking account and credit card account

transactions, were reduced from 40

seconds initially to between 5 and 7

seconds.”

Unlimited Data Storage

As predicted by Fiserv, the laboratory tests

showed that Corillian Online scalability is

only limited to the amount of memorydeployed. Initial trials were based on the

notion that 70 terabytes were going to be

needed to store 5 years’ worth of data.

Testing proved that only 30 terabytes were

necessary to hold 5 years of data and

scalability testing beyond that limit proved

to not materially degrade performance.

This is a major advantage for the bank,

which can now ensure that its PMM system

will be able to store large amounts of

customer data and deliver that data to

customers quickly. “With the way CorillianOnline is built, using the 64-bit version of

Windows Server 2008 R2 and Microsoft

SQL Server 2008 R2, the bank will be able

to add new web and application servers

incrementally to cope with much larger

system loads in the future,” says Lader.

“There’s no doubt the Microsoft solution

gives the bank the scalability and

performance it needs to handle increased
