Time for an SOA-open source mashup

This time Joe Mckendrick talk again about the (inevitable) mix between proprietary and open-source SOA implementation. See why:

It's an unavoidable fact; many SOAs will be running on the LAMP (Linux-Apache-MySQL-PHP/Perl/Python) and LAMJ (Linux-Apache-MySQL-J2EE) stacks.

Also:

The open-source JBoss, JonAS, and Apache application servers are also open-source phenomena that are becoming a huge part of the Web services/SOA scene. True, an SOA can be constructed entirely on commercial software with standardized interfaces. But an SOA running on a commodity open-source environment — built with open-source toolsets — is an incredible value proposition, far more than an SOA built on WebSphere, WebLogic, or Microsoft BizTalk and .NET. These app servers have steep licensing costs, and companies looking for low-end platforms to build their services can turn to open-source app servers such as JBoss and Apache Geronimo.

IBM

Consider the evolving strategies of two of the biggest infrastructure providers, IBM and BEA. IBM loves Linux, of course, one, because it's not Microsoft, and two, because the open-source OS provides a growth path for Big Blue's legacy systems ... ...For IBM, this is an entree into the small to medium size business market, and in response to the growing prevalence of open-source products such as JBoss and JonAS.

BEA

...For example, in October, BEA announces a "blended" approach to provide automated management and production-level support for customers using the open-source Apache Tomcat servlet container. Previously, BEA Systems has made overtures to the open-source folks, announcing that new updates to its Beehive component-based development environment were available through the open-source Apache Software Foundation. The Apache Beehive projects will also be able to run on JOnAS, Apache Geronimo, and Apache Tomcat server
