Distributed monolith architecture: What it is, why it happens, and how to fix it

A distributed monolith is a system that appears to be composed of separate services but functions as a tightly coupled monolith, often resulting from incomplete transitions from monolithic to microservices architectures. Despite being structured as independent services, these systems require coordinated deployments and share databases, leading to cascading failures and lack of service autonomy. This anti-pattern arises when teams fail to fully decouple architecture during modernization efforts, often due to organizational misalignment, reliance on synchronous communication, and shared resources. vFunction provides a solution by offering automated architectural analysis to reveal runtime dependencies and suggest actionable steps to redefine service boundaries and achieve true microservices independence. The platform emphasizes continuous modernization to prevent the re-emergence of distributed monoliths by monitoring architectural changes and maintaining decoupled service interactions.
