Removing barriers of delivering composite applications

Bereich: Whitepaper




Today, everything is mobile, connected,

interactive, immediate and fluid. To gain competitive advantage in the face of

rapidly changing technology and business dynamics, enterprises must accelerate

time to market. In an age of “instant” expectations, organizations have to be

able to respond quickly and effectively to changing business needs.




To help the business achieve these

goals, application teams need to deliver quality software on time and on

budget. Software developers and testers must speed up application projects and

lower the costs of development integration and testing. However, in the effort

to reduce costs and meet tight deadlines, application teams often need to make

tradeoffs on the expected level of performance and functionality, which can

lead to a sacrifice in application quality.



To do this rapid, agile development,

many organizations are moving to composite applications which are made up of

smaller units of functionality that can be developed and tested in quickly

achieved increments. This approach promotes agility because the smaller units

of functionality, or services, can be developed in parallel, accessed from

third parties, and reused in multiple projects. One downside to this approach

is that the entire process can slow down—and become more costly—if there are

dependencies on services that are not available when developers and testers

need them.



HP Service Virtualization software allows

developers and testers access to limited or unavailable services in a

simulated, virtual environment. This helps application teams lower costs and

reduce testing times by finding defects earlier in the application life cycle

when they are easier, faster and less expensive to fix. It helps improve

quality by enabling quality assurance (QA) teams test what otherwise couldn’t

be tested. It also helps isolate problems that are based on dependencies

between services in composite applications. This helps significantly reduce

delays and manage the costs and complexity of composite application development

and testing.
