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 ...
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...
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 applic...
It will take a while for SaaS in a Cloud Computing model to catch up with SOA. One obstacle for the pure plays in the cloud to join SOA is to recognize and deal with the increased testing and validation of data from even more diverse sources, as well as the governance and validation of...
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 ser...
Lately we've done a lot of research and publishing on how Dev & QA teams can ensure better quality throughout the software development and release lifecycle. But what about the IT Operations guys? It seems we are encountering a disconnect between the Enterprise Architecture and Integra...
Why does SOA seem to be moving forward a little faster in Europe than in North America? We've posed these kinds of questions in our surveys and forums, and often it seems that stateside, the term 'SOA' can polarize some IT teams - it's an 'either/or' decision at the architectural level...
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 ser...
Virtualization up until this date has largely lived in the data center, where it has indeed saved significant hardware and configuration costs for a given set of servers. But this value has yet to extend to SOA, which is by nature much harder to replicate in this fashion. When you have...
Many in the media are already calling on the demise of SOA and saying that it's just a passing phase, or it's really just a rebrand of the EAI space, or that it will be segmented only to certain integration-type challenges. We have a bit of a different take. The term SOA will go away o...
