Server virtualization provides an immediate reduction in hardware and configuration cost. But in focusing merely on the hardware side of virtualization, are we leaving money on the table? While organizations can reduce the number of boxes they need, and save the cost of replicating servers for virtual test beds, these servers are becoming commodities. What if we could apply the benefits of virtualization where we spend 80 percent or more of the IT budget – in the key enterprise software that runs our business and in the extensive development, support and maintenance costs of these applications? Today’s leading businesses rely on a mix of distributed technologies and new functionality, such as service-oriented architecture (SOA). Virtualization can improve the... (more)

How to Manage Application Performance and Load Testing in Virtual Environments

Gone are the days when you could test an interface to a single client/server app and know that you have performance covered. Today's interconnected systems such as fully integrated packaged applications, ESB-based enterprise platforms, and SOA make ensuring high-performance from application components and solutions increasingly difficult. On top of that complexity, we are increasingly su... (more)

Agile SOA Across the Lifecycle with LISA

John Michelsen's iTKO Blog In this series we are going to look at four aspects of the Agile lifecycle: test & quality management, application lifecycle management, IT operations, monitoring and performance, IT and SOA governance. For years, testing was an siloed activity that used different and unconnected tools within specific phases of the application lifecycle. First, a development team... (more)

SOA World Expo: The Agile Life Cycle for SOA

John Michelsen's iTKO Blog In the past, test “scripts” in TM tools were largely recorded as actual step-by-step instructions (in a Word doc or Excel spreadsheet) for a manual tester to point-and-click through a finished interface to test the application. When tests were completed, the tester would then “check a box” in the test management UI, to indicate that the test had passed or fail... (more)
