In the Windows Azure AppFabric May 2011 CTP, Microsoft released enhancements to Service Bus including the new message-oriented middleware features around Queues and Topics. “These enhancements will go live with an update to the commercially available service in a few months. Currently we’ve two versions of the Access Control service in our production environment: the January 2010 version and the April 2011 version,” AppFabric team stated.
"Until the production Service Bus is updated it continues to use the Jan 2010 version of the ACS. But once Service Bus is updated it'll also be able to use the new April 2011 version of the ACS. Once the Service Bus update goes live we strongly recommend to customers to update their Service Bus solutions to use the new version of ACS for two reasons:
- Service Bus will cease to use the older version of the ACS at some point in the future. In compliance with our lifecycle support policies for Azure, we'll provide you with 12 month notice before this event.
- The April 2011 version of ACS has great benefits," noted the team.
How to prepare
“Our LABS environment at AppFabric Labs already includes the enhancements to Service Bus, as well as the new version of Access Control. Hence, you can use this environment, free of charge, to start planning your migration and test it.
In the LABS environment already today, when customers create new Service Bus namespaces the system will generate a new AC namespace with the "-sb" suffix, but that namespace is created in ACSV2. This'll be the production experience when we release the update to Service Bus in a few months.
You can immediately start developing this new management code path creating rules against ACSV2 against the versions of Service Bus and Access Control that're available in the May 2011 CTP environment at portal.appfabriclabs.com,” explained the AppFabric team.
