COBOL Maintenance
We actively maintain legacy codebases, resolving performance anomalies and implementing new logic structures to meet evolving banking and regulatory guidelines, regardless of system complexity.
COBOL Migration Services
We execute secure, risk-mitigated migrations, transferring data definitions (Copybooks), files, and database connections from legacy COBOL environments to modern distributed platforms or cloud networks.
COBOL Technical Support
Ensure round-the-clock operational safety with dedicated support services. Our engineers deliver responsive troubleshooting, database optimisation, and support for your mainframe systems.
Benefits
Why COBOL Remains Vital for Australian Enterprises
Initially introduced in 1959, COBOL has systematically evolved and continues to support core fintech, healthcare, and public sector computing. Here are the core strategic advantages of this resilient programming language:
Global Business Standard
COBOL remains deeply embedded in the operations of major global financial entities and credit systems. Its unparalleled mathematical precision and file-handling efficiency make it irreplaceable for high-throughput batch processing.
Exceptional Readability
COBOL features a highly structured, self-documenting English-like syntax. By avoiding complex structures like pointers or implicit memory management, it enables stable maintenance cycles.
Modern Integration Capabilities
Modern COBOL compiles into managed code, integrating seamlessly with Java, C#, Docker containers, .NET, and cloud services (AWS and Azure) to leverage modern interoperability.
Platform-Agnostic Portability
We build COBOL applications that are highly portable, compiling cleanly across major platforms and operating systems, including enterprise Linux and UNIX servers, without code alterations.

FAQs
Q: What is COBOL and why is it still used by Australian banks and government agencies?
COBOL (Common Business-Oriented Language) is a high-level programming language engineered in 1959 for business and administrative data processing. Today, it remains critical because it handles over 80% of global in-person financial transactions. Its absolute numeric precision, stability, and speed in processing massive batch databases make it the bedrock of banking and public sector systems.
Q: What are the key technical features of the COBOL programming language?
Key features of COBOL include an English-like verbose syntax that improves readability, powerful batch file processing (utilising sequential, indexed, and relative access methods), high-precision decimal arithmetic, and robust data isolation structures that prevent memory-related system crashes.
Q: How can legacy COBOL codebases be integrated with modern AWS or Azure cloud environments?
Modern COBOL compilers compile directly to Java bytecode or .NET Common Intermediate Language, allowing seamless interoperability. Dev House Australia integrates legacy COBOL systems with cloud APIs, database architectures (like PostgreSQL or DB2), and microservices using secure web services and Docker containers.
Q: What services does Dev House Australia provide for COBOL legacy systems?
We offer complete lifecycle support, including mainframe system maintenance, automated performance testing, migration of source code to modern servers, database optimisation, and strategic consulting for full-scale software modernisation.
Q: How do you secure COBOL mainframe code and align it with modern compliance guidelines in Australia?
We secure mainframe deployments by enforcing secure Identity and Access Management (IAM), isolating database environments, using automated version control systems like Endevor, and auditing code for anomalies. Our procedures align legacy applications with local guidelines, including the Essential Eight recommendations and APRA regulations.
