Performance Modeling for Web based J2EE and .NET Applications

Performance Modeling for Web basedAbstract—When architecting an application, key nonfunctional requirements such as performance, scalability, availability and security, which influence the architecture of the system, are some times not adequately addressed. Performance of the application may not be looked at until there is a concern. There are several problems with this reactive approach. If the system does not meet its performance objectives, the application is unlikely to be accepted by the stakeholders. This paper suggests an approach for performance modeling for web based J2EE and .Net applications to address performance issues early in the development life cycle. It also includes a Performance Modeling Case Study, with Proof-of-Concept (PoC) and implementation details for .NET and J2EE platforms.J2EE and .NET Applications

Developing Consulting Skills

We all know that a consulting firm stands or falls according to how well its members perform. Few firms, however, have paid much attention to managing and developing their employees’ performance. Several factors conspire to make this so: other, more appealing activities are given higher priority; consultants are out working with clients; and few firms have the required skills.

Are You Prepared for the Consultant’s Nightmare?

CHANCES ARE, you could be the consultant in the fol-lowing scenario:<br /> Your expectations for the client are high as the engage-ment begins. Work gets under way as with most jobs, and you proceed much as expected. But try as you might, you cannot satisfy this client. In similar circumstances, other clients have been pleased with your recommendations. Not this time. This one wants more. And more. The scope of the engagement increases. The client dismisses your efforts to discuss a fee adjustment.
