Covers five key questions: team size, domain boundary clarity, operational maturity, independent scaling needs, and whether you're starting fresh or migrating. Introduces the modular monolith as a pragmatic middle ground, warns against the distributed monolith trap (services sharing a database), and provides C# code examples showing how to structure modules for clean extraction later. Includes a migration path pattern using interface abstractions to swap in-process and HTTP implementations via DI without changing calling code. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is a modular monolith in .NET and how does it differ from a regular monolith? A modular monolith is a single deployable application where internal domain boundaries are enforced through code organization, separate DbContext scopes per module, and DI module registration -- but everything still runs in one process. Each module owns its own code and data access layer, communicates with other modules only through interfaces, and can later be extracted into a true microservice when there's a concrete, measurable reason to do so. _Comparing monolith and modular-monolith patterns in .NET is easier with real architecture writeups surfaced on daily.dev._ ### How can I tell if my microservices are actually a distributed monolith? If two 'services' share the same database or DbContext and directly manipulate each other's tables, they aren't really independent, regardless of being deployed as separate processes. Signs include a schema migration in one service breaking another and both services contending on the same database rows. The fix is enforcing separate databases or schema ownership per service and defining module contracts (interfaces, events, DTOs) before building implementations. _Spotting distributed-monolith pitfalls before they cost you an outage is easier when relevant .NET architecture posts reach you through daily.dev._ ### At what team size does it make sense to move from a monolith to microservices in .NET? Teams with fewer than 10-12 engineers usually lose more productivity to microservices coordination overhead than they gain, while teams above 50+ engineers often hit monolith deployment bottlenecks and merge conflicts that independent services solve. The 12-50 engineer range is typically where a modular monolith wins, giving teams internal ownership without paying the full distributed-systems cost. _Deciding when a growing .NET team should split services is easier with practical framework posts like this reaching you via daily.dev._ ## Similar posts on daily.dev - [From Microservices Back to Monolith in C\#: When and How to Reverse Course](https://daily.dev/posts/from-microservices-back-to-monolith-in-c-when-and-how-to-reverse-course-b2t5nhtne) · We Are .NET · 1 upvotes · 0 comments - [When to Use Microservices \(And When Not To\) in .NET](https://daily.dev/posts/when-to-use-microservices-and-when-not-to-in-net-bexpylmbp) · Code with Mukesh · 12 upvotes · 0 comments - [Microservices vs Monolithic Architecture: What Nobody Tells You Until You've Lived Through Both](https://daily.dev/posts/microservices-vs-monolithic-architecture-what-nobody-tells-you-until-you-ve-lived-through-both-sju1wi5pt) · SitePoint · 41 upvotes · 10 comments - [Microservices Fundamentals Complete Guide](https://daily.dev/posts/microservices-fundamentals-complete-guide-qkaaco9uo) · Medium · 47 upvotes · 2 comments - [What Is a Monolith?
