title: Azure Service Bus: High Availability
body: <p>I'm currently building a hybrid-cloud solution that needs to write messages to a queue for later processing.  It is absolutely imperative that the queue is highly available (99.999+% uptime).</p>
  
  <p>My options are to read/write messages to a local ZeroMQ high availability pair, or an Azure Service Bus.  I would prefer to go the Azure Service Bus route, but can't find any documentation regarding high availability configuration for Azure Service Bus.</p>
  
  <p>Has anyone had success setting up Azure Service Bus for high availability? I understand that the SLA for a single instance of any Azure service cannot be changed.  I'm thinking more along the lines of the failover capabilities of Azure Web Apps.</p>
