ITKO Whitepaper: Key Capabilities of a Service Virtualization Solution  
Eliminating Software Development and Testing Constraints by Virtualizing Away Dependencies in the Environment

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 ITKO: Key Capabilities of a Service Virtualization Solution  
All large companies with a reliance on IT must deal with the constraints of systems such as mainframes, components under development and sensitive data sources that delay projects. Inevitably, teams try to either copy a complete environment in a test lab, or "mock up" responsive systems by coding their own versions for test purposes. This has become a costly and time-consuming endeavor.

ITKO 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: 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.

Whitepaper with Infosys and ITKO: Driving Better Business Process IT with Modern Software Quality  
To remain competitive, today's enterprise must be able to rapidly support new business processes with an increasingly heterogeneous, changing environment of IT systems. How does a business manager validate this new paradigm, when the old QA approaches do not mitigate the risk of failure? What methodology, systems and tools can we use for coping with the challenges of providing quality in today's agile business environments? How do you know that your CXO's business vision is matched by the quality of systems you invest in?

ITKO Whitepaper: The Next Frontier Value for Virtualization: Over-Utilized Systems  
Hardware virtualization technology is now par for the course in enterprise IT environments. Enterprises can realize immediate cost savings through the use of hardware virtualization to reduce server proliferation, consolidate desktop environments, and run numerous apps with a smaller combined hardware footprint. The key value espoused by leading virtualization vendors (such as VMware, Microsoft, Citrix, etc.) is making better use of "under-utilized" servers and intermittently used capacity that does not demand dedicated system resources to run.

ITKO Whitepaper: Demystifying Cloud-Based Testing and the Related Benefits  
Cloud computing has the potential to deliver enterprise software with increased flexibility and lower cost-of-entry. The Cloud provides benefits for development environments and test labs as well, increasing our options in how IT assets are provisioned to help teams across the software development and testing lifecycle.

iTKO/SAP Whitepaper : Validation and Virtualization of SAP Enterprise SOA Applications with ITKO LISA  
While SOA promises the business value of agility and reuse to SAP customers, this practice also adds IT risk, due to the complexity of maintaining application integrity across workflows that span multiple technologies. How can companies achieve functional and performance testing strategies that are complete enough to cover SOA? Replicating full test landscapes for development and testing activities, with all the components and data needed to validate a rich business process, can be expensive and difficult to create and maintain. Services might not be fully developed, or they might be owned by external providers and accessed over the Internet.

ITKO Whitepaper : Minimize IT Outsourcing Risk with Collaborative Quality  
Outsourced software development and testing has become a common practice that continues to experience significant growth. However, many organizations have learned the hard way that lower outsourced hourly staff rates do not translate into linear costs savings, and that although reducing costs is important, avoiding quality problems, schedule delays, and the associated risks are even more important.

ITKO Whitepaper: "Service Virtualization in Enterprise Application Development" 
Many large organizations are in the process of adopting hardware virtualization technology for the development of their dynamic enterprise applications. However, hardware virtualization is not appropriate or feasible in all circumstances, and by focusing solely on hardware virtualization we could be leaving opportunities to save significant time and money on the table.

This white paper introduces the practice of Service Virtualization as a key complement to hardware virtualization to facilitate the efficient development and testing of dynamic enterprise applications. Service virtualization involves the imaging of software service behavior and the modeling of a virtual service to stand in for the actual service during development and testing. Organizations that want to realize the full benefits of a virtualization strategy should evaluate both the hardware and software virtualization approaches described in this whitepaper.
