Modulith Instead of Monolith - Pragmatically Towards Microservices

Hendrik Lösch

Refactoring a 20-year-old codebase for multimillion-euro hardware demands precision. Discover how one team tamed their tangled C# legacy by shifting to a modular monolith instead of microservices.

#1 about 2 min

Refactoring a legacy monolith inside semiconductor manufacturing hardware

Context on upgrading a 20-year-old application controlling complex manufacturing machines without interrupting customer value.

#2 about 4 min

Technical debt and tangled architecture of the legacy monolith

An exploration of the unscalable architecture, entangled code base, and business constraints that make rewriting impossible.

#3 about 2 min

Identifying bounded contexts using domain-driven design principles

Breaking up the application by analyzing underlying business domains before touching the technical layers.

#4 about 3 min

Why microservices fail in resource-constrained hardware environments

Retaining a monolithic structure optimizes resource utilization, consistency, and debuggability on fixed hardware platforms.

#5 about 4 min

Defining the modulith approach for single deployment units

Moving toward a modular development model while deploying an optimized single-process monolithic application.

#6 about 4 min

Structuring modules around public interfaces and startup kernels

Encapsulating functionality into easily replaceable interface libraries integrated by a localized startup kernel.

#7 about 4 min

Managing hardware variations using product line software engineering

Controlling the complexity of different machine generations and vendor hardware by leveraging targeted software permutations.

#8 about 6 min

Implementing layered module architectures with foundation platforms

Organizing assets, features, and external integrations over a shared infrastructure framework that multiple teams consume.

#9 about 4 min

Extracting modules safely to restructure the legacy codebase

Encapsulating the old application as the first module and iteratively isolating domains without using legacy code.
