Cobol to Cloud Computing - Addendum

More options for cloud-enabling Cobol applications

Cobol to Cloud Options
In my previous article Cobol to Cloud Computing, I analyzed why moving the legacy batch programs written in Cobol to Cloud will be a good value proposition for enterprises. I also listed a few supporting PaaS platforms that will facilitate the migration of Cobol programs to Cloud.

I have learned of additional platforms, which is a welcome sign, as the one of the biggest concerns for CIOs migrating to Cloud is ‘Vendor Lock In' and the options available will make them happy.

Veryant isCOBOL Web Direct 2.0
With isCOBOL Web Direct 2.0, your organization can leverage existing COBOL syntax to develop and deploy a universally accessible, zero client rich Internet application (RIA) using standard COBOL screen sections and existing program procedure division and flow.

Leveraging AJAX technology, isCOBOL Web Direct 2.0 enables the deployment of fully-inter­active COBOL programs to the Web without changing basic application structure.

New applications and UI screens to be deployed with isCOBOL Web Direct 2.0 can be designed using the Eclipse-based isCOBOL IDE. Screens can be developed with the Screen Painter functionality available in the isCOBOL IDE and then tested for the Web leveraging an Apache Tomcat server running locally.

The product's data sheet talks about simple steps to deploy Cobol applications to Cloud.

  • Compile programs
  • Copy the resulting class files to the Cloud Platform's Java EE Application Server
  • Click on the "Reload" link on the server's management page
  • Navigate to the web application's URL,

Heirloom Computing / Elastic Cobol
This platform is in the final stages of release and was developed under the guidance of industry veterans with rich experience on Cobol migration solutions. Analysis of the product shows the following options available:

  • Enterprise Platform as a Service (EPaaS) deploys legacy COBOL/CICS applications to the Java platform for seamless execution on mainframes, open systems, and a variety of public and private cloud computing platforms
  • The platform provides graphical IDE That can help to build, debug and deploy applications to Cloud like Amazon EC2 platform
  • The platform converts the Cobol program into Java virtual machine code and then deploys them to a Java based PaaS platforms on Cloud
  • It uses the Cobol Declaratives to specific Java EE options like Package
  • The converted Cobol Program to Java is callable as local in process call or can be a remote call using typical Java RMI options
  • The IDE provides easier options to deploy to the Amazon EC2 Cloud platform
  • While the options provided are promising, we may need to wait for final product and associated case studies.

Summary
More information about these platforms can be obtained from respective vendor product sites.

The intention is to provide more information on the options that are available for migrating Cobol and legacy applications to Cloud and standard evaluation procedures can be utilized to choose the best one.
