Open source has been proven particularly effective when implementing SOA. Using open source reduces the cost of tools while providing a range of options from different providers. Having access to the source code also eliminates concerns about vendor lock-in. Finally, open source offers a broad and supportive community and ecosystem to support the SOA initiative. At the same time, commercial open source SOA tools carry with them the full support of a well-established vendor.
