Abstract

Service Virtualization was introduced at Nordstrom as a tool to help bridge the gap between development and operations teams.

Nordstrom’s Agile Transformation

CAN YOU RELATE TO THESE CONSTRAINTS?

• ENVIRONMENT INSTABILITY=LESS TIME TESTING

• TROUBLESHOOTING ISSUES=TIME-CONSUMING

• DATA CREATION=TOO MUCH TIME

• PROJECT TIMELINES =SEQUENTIAL DEVELOPMENT

•ENVIRONMENT STABILIZATION

•PARALLEL DEVELOPMENT

•CONTINUOUS DELIVERY

REPLACE REAL WITH VIRTUAL 80% of the environment components virtualized

PROVIDE REUSABLE TEST DATA Use virtual models to store all reusable data

REDUCE CROSS-TEAM SUPPORT The dependency on downstream DevOps teams was reduced by 75%

ENVIRONMENT STABILIZATION Service Virtualization removes performance lab constraints

Which project will make it to production? Do I really have to choose?

PERF NEARLY KICKED OUT OF THEIR OWN LAB!

SERVICE VIRTUALIZATION DECOUPLED THE DEVELOPMENT EFFORT

Challenges • Long development and

testing duration

• Unavailability of

Dependent Services

• Frequent changes in the

WSDLs and test

environment

• Setting up new

environments

Benefits

Enabled Parallel development

Improved same sprint test coverage with continuous testing

Stabilized environments for the consumer applications

Isolated the dev / testing teams from frequent WSDL , environment changes

Removed data dependencies across systems

Reduced test data set up effort by 75%

Removed all downstream issue analysis activities

$ Savings Cost of missing sprint target

Cost of environment downtime

Cost of data setup

Overall cost of sequential

development to release timeline

Service Virtualization Challenges

28

From a project’s Lessons Learned meeting

WHY DIDN’T WE USE SERVICE VIRTUALIZATION?

29

DELIVERY TEAM “FORGETS” TO TURN OFF VIRTUAL SERVICES

30

•HARDWARE / SOFTWARE COST

AVOIDANCE $80 million spent on building/maintaining lower environments per year

•REMOVE WAIT TIMES Loss of $1.2 million dollars in productivity per year

THE SERVICE VIRTUALIZATION BUSINESS CASE How did we sell Service Virtualization to Nordstrom Leadership?

31

WHAT’S NEW FOR SERVICE VIRTUALIZATION AT NORDSTROM?

VENDOR INTEGRATION

ENVIRONMENT PRODUCTION TESTING DEVELOPER SANDBOX

Provide access to external partners

for internal non-production

Nordstrom resources (services,

APIs, etc.)

Performance testing in production with

Service Virtualization

Our website developers will soon

have a developer image that

includes all virtual models for all

interfaces

Remove security risks by

eliminating the need to access real

Nordstrom resources

Customer data and credit data remains

secure

Increase the testing coverage of unit

testing

Provide external partners with

compliant data for testing; pairing

service virtualization with test data

management tools

Holiday volume tests run in production

environment without risk

Early integration testing uncovers

defects long before they are

introduced down the delivery pipeline

32

Development of a self-provisioning API allows developers to stand up virtual services SELF PROVISIONING OF VIRTUAL SERVICES

33

THEY DON’T SUPPORT PERFORMANCE

TESTING

THEY ARE UNABLE TO ADJUST THEIR

RESPONSE TIMES

THEY CHARGE USAGE FEES

THE TROUBLE WITH THIRD PARTY VENDORS Resiliency of applications put to the test
