The New Application RealityCompositional, loosely coupled, dynamic

Today’s state

– Designed for change – modular, interoperable

– Supporting business processes

– Supporting rich internet apps, mash-ups

– Incorporating external and cloud services

Agile business capabilitiesShared services / Composite apps

Desired state

•Applications deliver specific value but…

•They are costly, brittle, monolithic and proprietary and…

•Focused on initial requirements not built for change

Dev and QA in parallel

The New Application Reality Demands That IT Silos Must “Flatten”

What you have Scope is self-contained, minimal

dependencies, release to app ratio of 1:1

What you want

Shared, consumption brings dependencies, dynamic release to application ratio of 1:n

– Test compositions– Manage change– Mitigate constraints for dynamic,

in parallel testing

– Visibility– Lifecycle management– Ability to dev and test in parallel– Virtualize front and back-ends

What We’ll Cover Today

Pressure Points on Application Performance and Quality

8

Status quo quality management is too costly

It Starts With Economics

The issue– In the early days of

software, development was costly

– Advances in architecture, development tools, frameworks have shrunk dev time and cost

– However, advances in testing haven’t kept pace

– Testing now becomes the constraint

– It takes too long

– It happens too late in the cycle

– Defects are found late in the cycle

As Application Changes Outpace QA, a New Approach is Needed..

SOA; Web 2

Software Economics

ALM / Fluid Sourcing

Agile

Modern Quality Management

Need a cost effective approach to Software quality

New technologies; new deliverables; new approaches

A more holistic approach to software productionNew processes --

adaptable, iterative, results oriented

But what happens when the back-end is not available for testing?Without virtualization, the response is “wait”

And…agile development and distributed teams increase resource contention issues

24

Simplify Load and Performance Testing

Results

– Virtualize in 8 days vs. 2 yrs to develop

– Costs reduced 30% in Yr1, 65% in Yr2

Challenge

– 2 years to create costly “responder
