Performance is one of the major concerns in the cloud. But the question should not really be whether or not the cloud performs, but whether the Application in question can and does perform in the cloud. The main problem here is that application performance is either not managed at all ...

One sure fire way to keep budget and buzz away from your projects is for you and your department to be associated with incremental improvement. Projects can generally be classified into two categories. The first is “business transformation,” which includes projects that generate excite...

I’ve been programming since around 1982, first using an Apple in high school and then finally getting my first computer, the Timex Sinclair 1000 (2k of ROM and 2k of RAM), that same year. Both computers came with a form of the BASIC programming language and it was the start of my lifel...

Response times are in many – if not in most – cases the basis for performance analysis. When they are within expected boundaries everything is ok. When they get to high we start optimizing our applications. So response times play a central role in performance monitoring and analysis. ...

The OSGi framework is a popular platform for developing multifunctional desktop systems, enterprise systems and complex applications. OSGi uses a modular approach where each bundle is regarded as a relatively independent and separate unit. The framework controls maintenance-based tas...
