Exactly, appropriating the transient fault application block was the first step in getting our architecture to work on the cloud. However, connections to SQL are merely one part of the puzzle.<p>Instances of your worker nodes might also simply vanish.<p>* If you only have one node this is a &quot;hard fault.&quot; Users cannot use your application until the node is restored.<p>* If you have more than one it&#x27;s a &quot;soft fault.&quot; Users can often immediately retry their request.<p>* If your own architecture is correctly designed (many nodes with fault tolerance) it is a &quot;transient fault.&quot; Users are oblivious to the fact that one of your 100 nodes failed - even if that specific node was servicing their request.
