Act as a Senior Software Architect. Analyze a hypothetical monolithic e-commerce application that handles user management, inventory, payment processing, and order fulfillment within a single deployable unit. Outline a comprehensive strategy to refactor this system into a microservices architecture. Your plan must address the decomposition of the database, identification of bounded contexts, implementation of an API gateway, and strategies for handling data consistency (SAGA patterns) during the transition. Include a risk assessment regarding network latency and operational complexity.
