Manage application speed, scalability and reliability throughout the development process In light of today's compressed development cycles, multi-tiered application architectures and complex technologies, many organizations are challenged to get reliable yet scalable enterprise Java applications out the door in a timely manner. Devoting a small amount of energy throughout the development process to identify, address, and correct performance obstacles can lower the risks and costs associated w...

Java technology is great for accelerating time-to-market; but, performance and reliability risks can become a serious challenge. Because Java technology provides a higher level of abstraction, it affords developers only a limited understanding of—and control over—the way their...
