Federated SOA essential aspects: SOA Testing, SOA Identity and SOA Security

Here is an interesting article by Rob Barry titled: "In SOA, cloud resources may exacerbate security and file transfers issues." It highlights significant requirements for Federated SOA especially around large file transfer using Web services attachments. The article makes the following interesting points:

• Attachment sizes are increasing driven by cloud computing such as transferring large files to Amazon S3 or a companies internal cloud.
• MTOM and MIME are used now for real time file transfer over web services instead of FTP or classic MFT protocols.
• Identity is critical to Federated SOA.

Standards such as MIME and MTOM are now being heavily deployed. For a deeper understanding regarding how MTOM works, see "Intro to MTOM."
