What's the Business Value of Service Virtualization?

Speed innovation, accelerate time to market & reduce application development risks

With today's interconnected applications, a complete and realistic test environment is nearly impossible to stage. However, without reliable access to a complete and reliable test environment, testing is delayed or curtailed. The result is that organizations risk:

  • Brand erosion as faulty software drives away customers
  • Delays in time to market which diminish market share
  • Exposure to legal liability associated with application failure (security, reliability, performance)

That's where service virtualization comes into play.

How Service Virtualization Helps
Service Virtualization, with its ability to simulate complex environments, is truly a game-changer.

Service Virtualization is a method to simulate the behavior of system components in complex, component-based applications. Service Virtualization provides software development, QA, and performance testing teams access to a simulated version of dependent system components needed to exercise an application under test (AUT). Dependent system components are not always easy to access; in fact, a recent Parasoft study found that 30% of dependent applications are unavailable or difficult-to-access for development and testing purposes.

Service virtualization is primarily adopted in order to:

  • Speed innovation
  • Accelerate time to market
  • Reduce risks

Service Virtualization Speeds Innovation
Software development is a complex endeavor. In today's economy, innovation does not occur without an associated software component. Furthermore, software failure is a major business risk. Remember when Microsoft Windows hanging or crashing was an all-too-common occurrence? Do you think Microsoft could compete with Apple and Google today if Windows was still plagued by these former instability issues?

The ability to not only envision, but also accurately deliver, a flawless user experience with innovative technology is the fundamental challenge of software development. Service Virtualization is an essential technology for enabling innovation. Providing a simulated environment to more accurately develop and test software frees development resources to write more code, more accurately.

Service Virtualization Accelerates Time to Market
Every process has wait time inherent in its cycle. One of the primary goals of modern productivity software is to eliminate or reduce that wait time. The software development lifecycle (SDLC) is rife with wait time, which stems not only from the complexities endemic in developing code, but also from the fact that software development is a "high human touch" process.

Service Virtualization is a game-changing technology when it comes to shrinking wait time or down time. With a complete and easily-accessible development and test environment, development can better understand the impact of code changes, which in turn helps them code more efficiently. Moreover, testers can begin their testing cycles significantly earlier in the SDLC-promoting more accurate and more complete testing.

Service Virtualization Reduces Risks
Software development is an inherently risky endeavor. As software applications continue to evolve as the primary interface for all business processes, the physical and monetary damages associated with application failure increase exponentially. Furthermore, as applications become more interconnected and hosted in distributed cloud environments, the number of potential failure points escalates.

Software development organizations must combat these risks with more complete, more accurate, and more efficient testing processes. Again, Service Virtualization plays a major role in reducing risks by providing a simulated test environment that can be accessed by both development and testing organizations whenever they want, as early in the process as they want. Furthermore, Service Virtualization gives software development teams the unprecedented ability to test more thoroughly by executing "what-if" scenarios. For example, such "what-if" scenarios can exercise the application under test for security, performance, reliability, and failover.

Service Virtualization Webinar: Real Data and Real Results

voke-comcast-service-virtualizationWant to learn more about the business value of service virtualization? Join our Accelerating the SDLC with Simulated Test Environments webinar on Tuesday, October 22 2:00 PM EST / 11:00 AM PST. Theresa Lanowitz of voke and Frank Jennings of Comcast will share real data and real results from service virtualization.

First, Theresa Lanowitz will discuss the latest research findings on Service Virtualization business value and usage within leading IT organizations. Next, Comcast will share their first-hand experiences with service virtualization-including implementation challenges, best practices, and impact on schedules, costs, risk, and innovation. A significant portion of this webinar will be reserved for questions and answers from the distinguished panel.

The event will be moderated by David Rubenstein, editor-in-chief of SD Times.
