COBOL on Azure

Cloud Computing is big news at the moment and by using the Azure option for Visual COBOL for Visual Studio 2010 R3 you can create and deploy COBOL applications for the Azure platform.

What is the Azure option ?

It is an add-on to Visual COBOL, available on request, providing functionality to enable creation and execution of Azure Cloud Services. It consists of:

  • Run-time support
  • Demonstration programs
    • Integrated into the Samples Browser
  • Additional Help
  • Visual Studio IDE integration
    • New Cloud project category
      • ASP.NET Web Role
      • WCF Service Web Role
      • Worker Role


  • Windows Azure Tools for Visual Studio 1.3
  • IIS 7.0 with ASP.NET


  • Windows Vista
  • Windows 7
  • Windows Server 2008

Hints and Tips

  • You must run the Visual Studio IDE with elevated permissions
  • Use the Compute and Storage Emulators to develop and debug the application on a development machine
  • Be patient when deploying as the deployment may take several minutes to complete.

Limitations in the initial release

  • No Consolidated Tracing Facility
  • No native code execution
  • Partial trust is untested. All templates, including those for Microsoft languages, default to Full trust.
  • Full IIS 7.0 Web Roles are not supported. The <Sites> section must be removed manually from the .csdef file


  • Take a look a the help information. It contains a tutorial on creating and deploying a simple Azure application using the Visual Studio IDE.
  • Start the Samples Browser and take a look at the Azure samples.
  • Use Visual Studio Ultimate Edition for deployment to Azure if possible. The Intellitrace feature is extremely useful for determining problems in a deployed application.

Gael, don't forget to tell people about running a demo Azure application on the Micro Focus Enterprise Cloud Services.  As part of the Visual COBOL R3 launch, you can go to  and login (or register) and then click "Try it in the cloud".  This will start a cloud-based instance of Visual COBOL R3 with a the COBOL Azure plug-in and a demo COBOL Azure app.  Click "Debug" and it will bring up the Azure Execution Emulator (aka DevFabric) and Azure Storage Emulator (aka DevStore) right on your desktop.  Have fun with COBOL in ECS!
