Mainframe Modernization Services for AWS

Legacy mainframes weren't built for today's cloud-native demands. Cybic transforms your mission-critical mainframe workloads into agile, scalable AWS architectures — using proven refactoring, re-platforming, and automation strategies that minimize risk, preserve business logic, and unlock the full elasticity and innovation velocity of the AWS ecosystem.

Engineers modernizing mainframe systems to AWS cloud infrastructure

Our Mainframe Modernization Services

End-to-end AWS modernization covering migration strategy, code refactoring, data transformation, and cloud-native re-architecture.

Legacy System Migration

Cybic migrates mainframe applications to AWS with minimal disruption — preserving critical business logic while re-platforming workloads onto scalable, cloud-native infrastructure that reduces operational costs and eliminates mainframe licensing overhead.

Application Refactoring

We refactor COBOL, PL/I, and Assembler code into modern languages and microservices using AWS BLU Age and automated tooling — enabling cloud-native deployment without manual rewrites that introduce unnecessary risk or delay.

Data Warehouse Modernization

Cybic migrates mainframe-resident data stores and legacy EDW infrastructure to AWS-native platforms like Redshift and S3 data lakes — with ETL/ELT pipeline optimization, governance frameworks, and AI-readiness built into every layer.

Cloud-Native Architecture Design

We design scalable, infrastructure-agnostic AWS architectures — incorporating serverless, containerized, and microservices patterns with RBAC, encrypted data protection, and compliance with SOC 2, HIPAA, and GDPR standards.

Intelligent Automation Integration

Post-migration, Cybic embeds RPA bots, AI-powered workflow automation, and intelligent document processing into modernized AWS environments — replacing manual mainframe batch processes with real-time, orchestrated digital workflows.

Digital Transformation Strategy

Cybic's consulting practice delivers mainframe modernization roadmaps, TCO and ROI advisory, and AWS migration prioritization frameworks — helping enterprises move from legacy dependency to structured, measurable cloud execution.

Discovery & Mainframe Assessment

We conduct a comprehensive audit of your existing mainframe landscape — inventorying COBOL/PL/I codebases, batch jobs, data dependencies, and integration points — to produce a clear picture of modernization complexity, risk, and business criticality before any migration begins.
