Frequently Asked Questions

Can COBOL applications run in the cloud?

Yes, COBOL applications can run in the cloud through various approaches including lift-and-shift to cloud VMs, containerization with Docker/Kubernetes, or platform migration to cloud-native COBOL services on Azure, AWS, and other platforms.

What are the cost benefits of COBOL cloud migration?

COBOL cloud migration typically reduces infrastructure costs by 30-50%, eliminates hardware maintenance overhead, provides dynamic scaling capabilities, and offers enhanced disaster recovery at lower costs than traditional approaches.

How long does COBOL cloud migration take?

Migration timelines vary by approach: lift-and-shift migrations take 3-6 months, containerized migrations take 6-12 months, and full modernization can take 12-24 months depending on application complexity and business requirements.

What's the difference between Azure and AWS for COBOL migration?

Azure offers strong integration with Microsoft ecosystems and Micro Focus partnerships, while AWS provides comprehensive mainframe modernization services and broader cloud-native capabilities. The choice depends on your existing technology stack and specific requirements.
