Frequently Asked Questions
Do you have Questions for Monolith to Microservices in .NET ?
Let's connect and discuss your project. We're here to help bring your vision to life!
The main trigger should be a specific, measurable business constraint that blocks outcomes, such as release delays, scaling needs, or ownership handoffs. The focus is on addressing real bottlenecks rather than migrating simply for modernization's sake.
Besides migrating to microservices, you can retain and improve the monolith or evolve into a modular monolith .NET. These paths involve tightening boundaries, improving test and release discipline, and establishing clearer ownership without the operational overhead of distributed services.
Each independently deployed service should have exclusive ownership of its domain data and schema. This does not always require a separate physical database server, but other services should not directly write to its tables.
Operational readiness includes automated CI/CD pipelines with rollback capabilities, comprehensive telemetry and distributed tracing, strong service-to-service security, thorough testing and failure design, and established incident response and runbooks.
This limits blast radius and can support traffic rollback during early stages. Once the new service accepts authoritative writes, data reversal may require reconciliation or a forward fix.
Failures include premature extraction without business impact, shared schema coupling, unclear ownership, weak contracts, unprepared consumers, missing observability, inadequate testing, and irreversible data cutovers. Each requires targeted mitigation like stable contracts, ownership clarity, and robust testing.
If the boundary is unclear, data ownership is not viable, operational readiness is low, or constraints are mild, improving module boundaries inside a modular monolith is advisable. It reduces complexity and operational burden compared to premature microservices extraction.
Explicit API and event contracts, along with enforced backward compatibility and semantic versioning, ensure stable communication between services. These prevent breaking changes and support safe integration testing, critical to maintaining system stability.
The scorecard evaluates measurable constraints, independent scale and ownership needs, data ownership viability, contract stability, delivery and on-call maturity, security compliance, observability and testing coverage, incident response readiness, and the net benefit over added complexity.
Operational cost considerations include increased infrastructure, pipelines, telemetry, security, testing, on-call burden, and incident coordination across multiple services. Teams must ensure the business benefit outweighs these ongoing costs before proceeding.
Asynchronous messaging decouples services improving resilience and scalability but introduces complexity including message reliability, duplicate handling, ordered delivery requirements, poison message handling, and monitoring needs.
Incremental migration using controlled coexistence and the strangler pattern reduces risk by validating each extracted service individually. It allows rollback and gradual domain ownership shifts, avoiding the high cost and disruption of a big-bang rewrite.
