Changing nature of applications – where is the application?
Users and and the applications have moved to the cloud.
— Applications are no longer in the hands of call
centers. Losing simplified consumption and
training of application use.
— Applications are no longer on our enterprise
computers and green screens. Losing control
over delivery of business applications.
— Applications are in the hands of the end
users. Losing knowledge of how the
application is being used. Who is SME?
2
Increasing complexity and heterogeneity of environments
— Internal cloud initiatives are pervasive, data visualization is in
the cloud
— Production is the only true end to end implementation people
have for combined business workflows
— These environments are getting more complex – monitoring
of a application is spanning data centers and cloud providers
— Production visibility is the only accurate record of how
composite and SOA applications actually run in cloud providers

Dysfunctional Development Cycles
Meeting business demand has consequences in IT
 Most new applications are composite and highly integrated
 Agile has replaced waterfall development methodologies
 Much of the new application development is self-service and customerfacing making complexity exponential

Dysfunctional Development Cycles
Meeting business demand has consequences in IT
 Much of the information developers need is outside of their control when they need it
 Limited predictability on performance and where it’s going to break
 Traditional products and methodologies fail in this new cloud architecture
Result: Inability to release new functionality on time – over budget and poor quality


Unable to sufficiently test ESB for performance
 More complete SLA testing in less time
 Test lab costs reduced 30% in Year 1, 65% in
year 2
 Avoided over $30M in test lab hardware

Problem: Manual Labor
“My team of 50 is now a team of 250 in just 5 years due to
more components and releases.”
Solution: Automation
Achieve and maintain 85%-95% coverage after 1st test cycle.

Problem: Complexity
“We spend far more time figuring out where the bug is than
we do fixing the bug”
Solution: Collaboration
