Modern Application Support
Keep operating. Keep modernizing.
You don’t have to choose between legacy stability and digital innovation. Salem builds applications that run alongside your proven systems, bridging mission-critical legacy infrastructure with modern application capability.
Your modernization path
VAX · Mainframe · Solaris · SCADA
APIs · ETL/ELT · Microservices
.NET · Python · Java
Zero downtime. Full validation. Parallel operation.
Four development stacks. One integration philosophy.
Build modern applications that talk to legacy systems, not despite them, but because of them.
Microsoft ecosystem
For organizations with deep Windows heritage. Salem combines Microsoft platform expertise, including C# and the .NET stack, with modernization strategy, so no rip-and-replace is required.
Modern .NET
Modernize on the Microsoft stack. Build C# and .NET applications, including ASP.NET web front ends accessible from any browser, that connect cleanly to aging databases like Oracle and Oracle Rdb.
Python and Java
Open-source modernization at global scale. Java powers enterprise backend and microservices, while Python drives data, analytics, and industrial IoT. License freedom and a deep talent pool, without vendor lock-in.
Agile development
De-risk complex modernization through iterative delivery. Break legacy replacement into manageable chunks, then fail fast and learn continuously.
Your complete modernization ecosystem
Modern app support doesn’t stand alone
Modern Application Support is the development engine for Salem’s full modernization practice. It integrates with our existing services:
- Application migration – move mission-critical apps without disruption
- Application customization – extend value without full replacement
- Porting – move from obsolete platforms to modern environments
- Maintenance – keep legacy systems humming during modernization
- Dashboard and reporting – unify monitoring across your infrastructure age spectrum
Result: hybrid infrastructure that actually works.
How they work together
- Maintenance – keep legacy systems stable
- Modern apps – build new capability
- Customization – adapt legacy for coexistence
- Integration layer – APIs and data sync
- Migration – phase out when ready
- Scale – modern apps take on new workloads
Modernization in action
Real scenarios. Real industries. Real results.
Manufacturing
Production line modernization
Challenge
Aging Windows and SCADA systems still control production. Operations need real-time visibility and AI-driven optimization without disrupting the factory floor.
Salem approach
A modern .NET dashboard pulls live SCADA data through an API wrapper. A Python analytics engine surfaces optimization opportunities. New control logic runs in parallel with legacy systems, with cutover by production line rather than all at once.
Defense
Multi-legacy consolidation
Challenge
Multiple acquisitions left a fragmented IT landscape of mainframe, OpenVMS, Unix, and Windows. New applications must talk to all of them without rewriting proven business logic.
Salem approach
Agile development validates integration patterns iteratively. C# and Java microservices wrap OpenVMS and other legacy systems in modern APIs. Windows and .NET front ends consume them safely. One IT landscape, with legacy systems still stable.
Energy
Compliance-ready modernization
Challenge
NERC compliance requires audit trails and real-time monitoring. Aging systems lack both, and full replacement is cost-prohibitive and risky.
Salem approach
A modern .NET reporting engine surfaces compliance data. A dashboard aggregates legacy telemetry with full governance. Integration preserves the audit trail throughout, with no compliance gaps during transition.
