vFunction introduced new features designed to help software teams accelerate application innovation while maintaining resilience and reducing technical debt. The platform’s groundbreaking software architecture governance capabilities enable organizations to set rules that serve as guardrails for managing distributed applications, preventing microservices sprawl. These rules allow engineering teams to monitor their architecture, receive alerts, ensure services connect only to authorized servers, enforce service boundaries, and maintain proper database-to-microservice relationships. Enhanced flow analysis tools, including live flow coverage for monoliths and sequence diagrams for distributed systems, align design intent with real-world implementation. By comparing production flows with tested flows, organizations can identify gaps in testing and coverage. vFunction’s domain-driven design approach, combined with its robust production flow analysis, provides the architectural clarity and control needed to boost engineering speed, application scalability, and resilience.
“Good software architecture matters to overall application health and business success, but it’s hard to enforce it without the right tools, particularly for microservices,” said Moti Rafalin, CEO and co-founder of vFunction. “It’s all too easy to introduce unnecessary dependencies that violate architectural best practices and, in turn, result in more technical debt. vFunction addresses these complexities, helping teams maintain architectural integrity for resilient and scalable applications from release to release.”
“When application architectures become too complex, resiliency, security, performance, and developer efficiency suffer,” said Jim Mercer, program vice president at IDC. “vFunction is helping enterprises gain a deep understanding of their software architecture and improve system governance, which can enable software engineers to work faster and maintain healthy microservices. With comprehensive flow analysis, vFunction helps teams visualize production flows, to compare with architectural blueprints. By identifying potential gaps in coverage, vFunction helps resolve problems before they affect performance.”
Architectural Governance Rules Drive Effective Development and Speed Releases
Lack of software architecture governance and development with minimal oversight has spawned complexity within enterprises, resulting in applications riddled with too many dependencies, multi-hop flows, circular dependencies, and duplicate functionality. Particularly in distributed applications, core services should be independent to ensure resiliency, fault tolerance, and scalability. However, without enforced guidelines architectural drift often occurs – where the application architecture’s current state moves away from the target state – compromising overall application health. Software architects also struggle to guide teams toward optimal application architecture, when they lack visibility into how it evolves in production.
vFunction now offers true software governance, allowing organizations to set architectural rules that act as guardrails to maintain architectural principles from release to release. The company implemented AI algorithms to categorize services into layers like API, core, and composite services. New tagging capabilities provide context and enable rule creation between services. For instance, dependencies between core services or API services can trigger alerts or block pull requests in CI/CD pipelines. By setting architectural governance rules, teams can develop and release faster without impacting application health.
Comprehensive Flow Analysis Aligns Application Reality with Design Intent, Resulting in More Resilient Architectures
With the introduction of comprehensive flow analysis capabilities, vFunction’s architectural observability platform addresses a critical gap in the management of monolithic and distributed microservices applications. It provides insights into actual application usage patterns versus documented expectations and identifies efficient or overly complex flows. This allows teams to proactively tackle architectural issues before they significantly impact performance.
Live flow coverage for monolithic applications goes beyond traditional profiling tools. Unlike existing solutions that focus on test environments or code coverage, vFunction constantly monitors production environments, providing insights into resource usage of specific flows and enabling comparison between production and pre-production flows. This unified approach allows developers to assess the real-world effectiveness of their tests by offering a more accurate understanding of application behaviors and test coverage in relation to real user journeys, filling a crucial gap in current application monitoring and management practices.
Sequence flow diagrams for distributed applications provide a deep view into application flows so developers and SREs can better distinguish between efficient processes and those at risk of failure due to excessive complexity. By visualizing flows as sequence diagrams in distributed architectures, vFunction solves the previously daunting task of tracking problematic flows through code and monitoring their changes over time. By correlating APM incidents with architectural issues identified by vFunction, engineering teams can significantly reduce mean time to repair (MTTR).
vFunction serves as a system of record for live application architectural diagrams, allowing teams to recognize drift in specific flows, track changes, and manage tasks as sequences evolve. Unlike traditional application performance management (APM) tools that collect performance data, vFunction’s solution focuses on architectural drift, highlights overly complex flows that may compromise system resiliency, and notifies teams of significant changes. This capability, combined with the ability to export diagrams for each system flow, empowers development teams to maintain architectural integrity and optimize application performance in complex distributed environments.
Rafalin continued, “With our latest advancements, we’re helping teams better manage architecture and understand comprehensive business and user flows so they can avoid the most damaging types of technical debt.”
