You can use vFunction to analyze existing Java and .NET applications and break monolithic codebases into modular microservices. It inspects application runtime behavior to detect dynamic dependencies, shared databases, and architectural bottlenecks that static analysis misses. The system generates functional specifications, architectural maps, and integration tests directly from production execution data. Engineering teams can feed this architectural context into AI coding assistants like Claude Code to automate code refactoring, migrate legacy workloads to containers, and convert proprietary databases to open-source options.

What vFunction does

Analyze runtime architecture of monolithic applicationsIdentify domain boundaries within legacy codeGenerate architectural specifications for AI code generationExtract target microservices from monolithic frameworksCreate automated tests based on runtime executionPlan container migration paths for legacy workloadsAnalyzes application runtime dependencies and actual behavior in productionGenerates structured specifications and integration tests directly from live code executionProvides architectural context and guardrails for AI coding assistantsConverts monolithic Java and .NET workloads into modular microservicesAssists in database migration from SQL Server to PostgreSQLMaps VM-hosted applications for migration into containers
