This article, by Ryan Knight, compares two similar products: Adobe’s LiveCycle Data Services (LCDS) and Open Source Blaze Data Services. The comparison is necessary to know the differences between the two products in order to choose the right one for a certain situation.
Read: Blaze Data Services or LiveCycle Data Services?
Since LCDS comes in four editions, there are five products in total:
- Blaze Data Services - Free and Open Source edition
- LiveCycle Data Services Community Edition - A supported version of Blaze DS
- LiveCycle Data Service Single-CPU License - A free version of the commercial edition with the additional features but limited to a single CPU
- LiveCycle Data Services - The paid version of the commercial edition with support
- LiveCycle Data Services Enterprise Suite – The paid version plus PDF Generation, Forms, and Digital Signatures, and others.
Choosing one of them needs to take into consideration the following most important factors: the need for support, the need for data management services, and the need for opening hundreds of concurrent connections. Ryan explains which product to choose considering those needs.

If anyone is interested in learning how to build 5-6 projects in Flex or AIR to talk to a custom build of BlazeDS with an Apache Axis SOAP stack (v 1.4), you can download it from www.web2open.org/courses.html. This course is self paced and you are free to take the materials, code samples and teach them in your own 'hood. Ciao!
Theoretically your conclusions regarding the "useless NIO" may be right if you live in the world of servers with unlimited power CPU/Memory and when each Java thread won't take a specific amount of resources in a JVM with a limited heap size.
Our company, Farata Systems, did some real performance tests hitting BlazeDS hard emulating thousands user requests with a PROFESSIONAL stress test software. This test put the Tomcat/BlazeDS down reaching 800 users. After that, we've created our own solution that works with Jetty server and can be stable with at least 5K users hitting Jetty/BlazeDS. Here's a video recording of this stress test:myflex.org//demos/JettyBlazeDS/JettyBlazeDSload...
Jetty's suspend/resume thread architecture was supposed to be used as a base for Servlet 3.0 spec, but because of some weird reason it didn't happen, so our solution works with Jetty only at this time.
Brian Marick takes us through a quick tour of the most important values and challenges to adopting Agile successfully (they aren't the typical challenges and values we hear in the community).
The line between development and architecture is tricky. Does it exist at all? Is an ivory tower actually needed? There's a balance in the middle, but how do you move from developer to architect?
The word 'authority' sometimes produces an allergic response in hard-line agilists. Freedom and authority – both are bad if misused and both are good if used in right spirit for a noble cause.
"Getting Started with Grails" brings you up to speed on this modern web framework. Companies as varied as LinkedIn, Wired, and Taco Bell are all using Grails. Are you ready to get started as well?
Those familiar with only ITIL V2 often scoff at the thought that ITIL could serve as a governance framework for SOA. With ITIL V3, the focus of the framework shifted towards service-orientation.
SpringSource CTO Adrian Colyer discusses AspectJ, SpringSource's dm Server and tc Server products, OSGi and Scrum.

For Grady Booch the foundation of a good architecture is patterns, SOA being just one of many patterns. In this Second Life presentation, Booch attempts to bring more clarity on what architecture is.
