Thanks for the informative informatin.

There are two free newly released products that will add to the ease of creating scalable websites and web services applications.

One of the main problems that can face a developer is to develop scalable sites that can handle a large number of concurrent users without the cost of expensive hardware and development, not to mention the cost of the hardware.

ZeroPoint, LLC. has just released their new Java Application Server and Database Accelerator for free! These two products, ZAppSvr and ZCache, will increase your ability to develop scalable, dynamic web services and database applications without the cost of heavy weight frameworks and expensive hardware.

ZAppSvr is a new Java Application Server combined with a powerful Load Balancer. The result is a perfect platform for developing Web Services from small to extreme. Clustered web applications are easy to build and debug.

Useful for nearly any application small to large and it is now FREE. The load balancing feature and dynamic HTML capabilities makes this a great tool for easily creating dynamic, scalable web sites and web services.

Short learning curve, easy debugging, and scalability make this technology worth investigation!

ZCache is an SQL database accelerator that simplifies database access, offers 100xPlus performance increases, and is accessible by any technology that speaks IP. More than a read-only technology, it maintains data in memory and keeps data up to date during write operations, and speeds any serious database intensive application whether on the Web or a local network.

Both applications are written in 100% Java. Take a look at them at www.zeropoint.com.

J ,

Thanks for the feedback! Credit for the "clarity and style" goes to Bill Venners for his expert editorial and writing skills.

Our goal was to write this article for a general audience with such people as project managers or non technical managers in mind. A lot of times, as it has been our experience, web-based application performance issues require collaboration of various groups of different disciplines who are not all developers.

Thanks for the feedback. The objective of the paper however, was to provide a guideline for the folks who are trying to resolve a performance problem for the first time and not to promote any specific product or services because there are lots of products out there. If you would like to promote your product the best way is to call Artima and get a Pavilion page!

Regards,


Arash

Bob,
You are right on the money! The first time I dealt with a performance problem I had no idea how to approach the problem and was very disorganized in resolving it. I would try different things and then once it didn't work I would think ok what is next. That is why it took us a long time to resolve the problem. However, Once you have plan in place you get a clear picture of what you have to deal with in terms of the issues at hand. In addition, you portray an image of "I-know-what-I-am-doing" to other (business) units who are watching your team resolve the problem.

Regards,

Arash
