vFunction

Conquer application complexity with architectural observability

Freemium

Description

vFunction offers an AI-driven architectural observability platform designed to help engineering teams understand and manage complex application architectures. It tackles challenges like technical debt, architectural drift, and the difficulties of modernizing legacy monolithic applications. The platform provides deep visibility into application structures, dependencies, and runtime behavior, enabling data-driven decisions for architectural improvements.

By leveraging AI, vFunction automates the analysis of both monolithic and distributed systems. For modernization projects, it helps identify domain boundaries, quantify technical debt, and suggests refactoring paths to transform monoliths into modular, cloud-native microservices, including automated code extraction and API generation. For ongoing management, it facilitates microservices governance by visualizing distributed architectures, monitoring for drift, identifying complex flows, and allowing teams to enforce architectural patterns and standards to prevent sprawl and maintain system integrity.

Key Features

AI-driven Architectural Discovery: Automatically maps services, resources, domains, dependencies, and flows.
Architectural Visualization: Offers multiple views like call trees, class diagrams, and C4 model support.
Technical Debt Analysis: Identifies and quantifies architectural technical debt, complexity, and risk.
Monolith Modernization: Analyzes monoliths, identifies domains, and suggests refactoring for modularity.
Automated Microservice Extraction: Automatically extracts code for microservices and generates APIs/client libraries.
Framework Migration Support: Integrates with tools like OpenRewrite for automated framework upgrades (e.g., to Spring Boot, Quarkus).
Microservices Governance: Monitors distributed architectures for drift, identifies anti-patterns (e.g., circular dependencies), and complex flows.
Architectural Standards Enforcement: Allows setting rules for dependencies between services and resources.
Cloud Compatibility Analysis: Assesses domain suitability for cloud platforms and generates migration tasks.
Integration & Exporting: Exports data and tasks to systems like Jira and Azure DevOps.

Frequently Asked Questions

Is vFunction on-prem or cloud-based?

vFunction is primarily installed on-premises to keep data secure within the user's environment, though cloud-based deployment can be accommodated on a case-by-case basis.

What languages does vFunction support for modernization?

vFunction supports Java applications (version 1.6 and newer) and .NET applications (version 4.0 and newer).

How does vFunction handle user limits and pricing?

The platform allows unlimited users; pricing is based solely on the number of applications (for modernization) or services (for governance) being observed.

What kind of agents does vFunction use for governance?

vFunction utilizes tracing data from standard OpenTelemetry (OTel) agents. No additional agents are required if OTel is already implemented.

Does vFunction offer trials?

Yes, vFunction offers a free tier for architectural governance (up to 10 services), a 14-day free trial for broader governance needs, and a 30-day free trial for application modernization.
