A practical guide to incrementally replacing legacy monolithic systems using the strangler fig pattern, with routing strategies, data synchronization techniques, and rollback safety nets.
Apply Domain-Driven Design bounded contexts to real codebases by defining clear boundaries between subdomains, managing context mapping between teams, and avoiding the common pitfall of sharing domain models across services.
Implement event sourcing in audit-heavy applications where every state change must be traceable, using append-only event stores, projections, and snapshot strategies that balance compliance requirements with query performance.
Apply the strangler fig pattern to incrementally replace legacy systems with modern architectures using practical examples of route-based migration, feature flags, data synchronization, and rollback strategies that keep production running throughout.
Implement hexagonal architecture with concrete TypeScript examples showing how ports define business contracts, adapters handle infrastructure, and dependency inversion keeps the domain layer testable and framework-independent.
Practical strategies for identifying, implementing, and integrating bounded contexts in domain-driven design, with concrete patterns for context mapping, anti-corruption layers, and shared kernels across service boundaries.
Design event mesh architectures that route events across multiple clouds and regions with dynamic topic routing, protocol bridging, schema governance, and eventually consistent delivery guarantees.
Implement clean architecture patterns that separate business logic from infrastructure concerns, making applications testable, maintainable, and adaptable to changing requirements or technology choices.
Design cell-based architectures that isolate failures to small blast radii, enable independent scaling, and prevent cascading outages across distributed systems.
Explore edge computing patterns that bring computation closer to users, reduce latency, and enable new capabilities for modern web applications and APIs.
Learn how to apply the strangler fig pattern to incrementally migrate legacy systems to modern architectures without risky big-bang rewrites or extended downtime.
How to implement the saga pattern to manage distributed transactions across microservices — comparing orchestration versus choreography approaches with practical TypeScript examples and compensation logic.
