AS4: The simple formula for better B2B
B2B IntegrationB2B standards have been around for decades and are constantly evolving. As B2B standards have advanced, many organizations moved from EDI to EDIINT. As service-orientation become a key architectural principal, web services became a the recommended way for organizations to interact (API’s notwithstanding). The ebXML Messaging Services (ebMS) standard provided a path for organizations to exchange B2B documents using web services.
Now, there’s a new kid in town called AS4. One might ask if AS4 is just one better than A3. Of course, it doesn’t really work that way! Another question might be “how is this related to ebMS (ebXML Messaging Services)?”
So what is AS4? I like to think of AS4 using this formula:
AS4 = ebMS – (extra stuff) + AS2 = better B2B
