What Is Service Virtualization and Why Does it Matter?

What Is Service Virtualization & Why Does it Matter?

A recent blog by Hurwitz & Associates analyst Marcia Kaufman defines service virtualization:service virtualization definition

“Service virtualization is used to simulate the behavior of components in an application so you can perform an accurate and timely test in a world of complex interrelated applications. Production services that may not be available for integration testing can be virtualized so the testing can take place at an appropriate time in the software development process.”

Kaufman also explores the benefits of service virtualization:

“One of the biggest impacts of service virtualization for developers is the ability to validate integrations much earlier in the application life cycle. The software development team can move beyond unit testing and overcome many of the roadblocks that inhibit timely, efficient, and cost effective testing.”

We strongly encourage you to read her complete What is Service Virtualization? article. After exploring why service virtualization is so critical given current methods for writing and combining code, Kaufman presents 5 key things to know about service virtualization. These service virtualization considerations can briefly be summarized as:

  1. Consider how service virtualization can complement your testing methodology.
  2. Use a cost/benefit analysis to determine which services are prime candidates for service virtualization.
  3. Recognize that service virtualization can help you detect errors during all testing phases.
  4. You can define a service virtualization virtual asset by recording the behavior of an existing component.
  5. Plan to rapidly shift back and forth between real and “virtualized” components when you’re testing.

Everyone wants the rainbow - reduced IT costs, scalability, continuity, flexibility, manageability, and innovation. But in order to get to that collaboration rainbow, you need the cloud! In this presentation, we'll cover three areas: First - the rainbow of benefits from cloud collaboration. There are many different reasons why more and more companies and institutions are moving to the cloud. Benefits include: cost savings (reducing on-prem infrastructure, reducing data center foot print, reducing IT support costs), enabling growth (ensuring a highly available, highly scalable infrastructure), increasing employee access & engagement (by having collaboration tools that are usable and available globally regardless of location there will be an increased connectedness amongst teams and individuals that will help increase both efficiency and productivity.)
