Integração – Relay/Conexão Windows Azure Service bus relay Aplicação Internet Speaking Points: In addition to queues, the Service Bus also provides a relay capability that can be used to connect through networks and enable hybrid applications. To see this in action, we’ll take a look at another simple scenario. In this case we have a SQL database in our on-premises environment (for our demo, my local laptop) and the data is exposed through a simple WCF service By using the Service Bus relay, we can enable connectivity to our WCF service through Windows Azure On the front end, we have a mobile web application created with ASP.NET MVC running as a Cloud Service in Windows Azure. This app will connect to the WCF service through the relay and serve up the data to users. Empresa Aplicação atrás do firewall

Faça um teste http://WindowsAzure.com Speaking Points: All of the features I demoed today are available now either in released or preview form. The services that had the preview tag next to them in the management portal are currently in preview mode, meaning that they are not yet final. These services will be coming out of preview next calendar year. Working hard on getting them done as soon as possible. If you haven’t gotten started yet with Windows Azure, I encourage you to go to WindowsAzure.com and sign-up for an account. If you have an MSDN subscription you can activate up to $3700 worth of yearly Windows Azure benefits. Otherwise you can sign-up for a free trial and get started.
