predic8 offers open source tools that help to run a successful SOA.
Captures, displays and manipulates SOAP messages. The XML beautifier makes it easy to analyze even complex messages.
Lightweight registry that observes Web Services to insure a healthy SOA. Monitors and logs the availability of services. If a WSDL description of a service has changed the registry will detect the change.
Administrators, even without any knowledge in programming, can now learn in our ActiveMQ training course how to install, administrate and operate a message broker. Among other things lots of exercieses teach you to:

This article compares some popular frameworks which are used for object serialization. Cause of versioning, small footprint and high performance these frameworks can be interesting for remote communication, too. Besides Google's Protocol Buffers and Facebook's Thrift we also compare some open source frameworks like Etch, Hadoop Avro and Hession.
Distributing the load among a cluster of servers can accelerate a slow running Web Service. Especially a Web Service that consumes a lot of CPU power and that serves a large number of concurrent clients. The open source SOAP intermediary Membrane SOA Monitor now comes with a loadbalancer for Web Services. The URL rewriting functionality of the monitor, that modifies endpoint addresses and schemaLocations in WSDL documents works together with the loadbalancer. The architecture of the balancer is based on some Spring beans and is therefore very flexible. For example, the dispatching strategy that selects an endpoint in the cluster can be exchanged by other implementations.
The Web Service Description Language is used to describe Web Services ubiquitously. Tools reading WSDL documents make it easy to implement or invoke a service. Usually it is not neccessary for programmers to read WSDL in order to create or consume a service. On the other hand WSDL is an essential technology for SOA experts. They write guidelines and rules for WSDL and they have to do quality assureance for WSDL documents and generators. This online article explains how to read a WSDL document using the description of a free Web Service for banking codes. The WSDL is analyzed step by step and transformed into a diagram showing the structure of WSDL.
