AZR301
Expectations
Basic understanding of Azure (This is a 300 level)Will only lightly touch on newly announced features
Virtual MachineVirtual Network
Questions
What new steps do I need to take to build and deploy a supportable Azure application?How is troubleshooting different in Azure and what tools should I take advantage of?What signs should I look for before calling Microsoft support?

Platform as a Service (PaaS)Support tradeoffs exist between Azure technologies
SQL Azure vs. Azure StorageService Bus Relay vs. Public Web Services
Develop

Develop - Instrumentation
Ensure all data is collected when a failure occurs connecting to Azure services:
SQL AzureAzure CacheAzure Service BusAzure Storage
Develop – Setting Instrumentation
Use Windows Azure Diagnostics configuration fileCustom counters need to be set in code

Windows Azure Diagnostics Configuration XML
Develop – Start Up Tasks
Used to configure the VM for your applicationMost common use is IIS settings
Can also use it to install software

Startup Tasks – Installing Software
Test – Load Testing

Azure Compute Roles
Role instances “Never Ready”Communication issues between role instances
SQL Azure Clues
System.Data.SqlClient.SqlException: The service is currently busy. Retry the request after 10 seconds. Code: 65539
at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection)
Azure Cache Clues
There is a temporary failure. Please retry later. (One or more specified cache servers are unavailable, which could be caused by busy network or servers. For on-premises cache clusters, also verify the following conditions. Ensure that security permission has been granted for this client account, and check that the AppFabric Caching Service is allowed through the firewall on all cache hosts. Also the MaxBufferSize on the server must be greater than or equal to the serialized object size sent from the client.)
Azure Service Bus Endpoint Clues
ATOM feed is emptySystem.ServiceModel.EndpointNotFoundException: The endpoint was not found. Please ensure that you can connect to the internet using HTTP port 80 and TCP port 9350.
