CA LISA Whitepaper: Service Virtualization and the DevTest Cloud: Realize faster cycle times and cost efficiencies through Cloud-based development and test environments with Service Virtualization
Software development practices have lost their sense of equilibrium, and the Cloud can help bring it back. The forces of increased complexity, interconnectivity, geographic distribution, and pace of change are invalidating some of the fundamental assumptions we have relied on in software development process. In turn, this has created an imbalance in the economy in which software development operates.

Whitepaper with Infosys and ITKO: A Practitioner's Approach to Successfully Implementing Service Virtualization
Service virtualization envisions a promising solution to alleviate dependency constraints. However, its implementation can pose confusing questions for IT architects. Success in virtualization initiatives comes from understanding the three W's (Why virtualize, What is the virtualization process and When to virtualize) and one H (How to virtualize). This paper focuses on the "What" of the virtualization process and also lays out a practitioner's approach/methodology to successfully implementing Service Virtualization.

Whitepaper with Infosys and CA LISA: Service Virtualization for Modern Applications
Disruptive innovations such as the internet have repeatedly forced businesses to change quickly or be relegated to history. Every such disruption asks a simple question of service functions in an organization - can they evolve quickly enough? Modern approaches such as service oriented architectures (SOA), along with other similar distributed application architectures, carry great promise and can provide an effective model for lean, agile and componentized IT that can adapt quickly. SOA is one of the most widely adopted enterprise architectural methodologies, but its implementation is anything but simple. Since classical testing methodologies and tools do not fit modern applications well, we have evolved newer more rigorous approaches and products to address increased software complexity and change. Service Virtualization is one of the latest ideas that can provide a faster time to market for software, with higher quality and lesser risk.
