Transform Your Mainframe into an Agile Digital Ecosystem

Mainframe Modernization doesn't mean starting over, let OpenLegacy show you how to take an automated approach to creating APIs and microservices bypassing traditional middleware to connect directly to mainframe systems - Speeding new innovation development from months to days.

Top Mainframe Challenges OpenLegacy Addresses

Accelerate time to market

Monolithic architecture

Difficulty migrating from monolithic mainframe applications to modern microservices architectures. The languages and approaches are very different making integration and communication complex.

Reliance on middleware

Reliance on complex middleware for connections. Traditional middleware creates performance bottlenecks and maintenance headaches compared to more modern integration approaches.
Future-proof your innovation strategy

Complex and hard to reach data sources

Accessing and extracting data from legacy mainframe data sources like VSAM files. This is a manual, time-consuming process but that data needs to be leveraged for things like regulatory compliance.

OpenLegacy Hub Prebuilt Connectors for Mainframe Sources

OpenLegacy's connector technology acts as a bridge between legacy databases and modern applications - helping organizations leverage their existing investments in legacy systems while allowing them to meet the demands of modern IT environments more effectively
