Goodbye Microservices, Hello Self-Contained Systems

Simon Martinelli

Are microservices drowning your team in synchronous API complexity? Discover how Self-Contained Systems bundle UI, logic, and data to create resilient, autonomous, AI-ready architectures.

#1 about 2 min

Handling data integration and eventual consistency

Integration between self-contained systems relies on eventual consistency, linked web interfaces, and asynchronous events rather than synchronous service calls.

#2 about 2 min

Four core advantages of self-contained architectures

Self-contained systems offer robust resilience, separate domain-specific quality requirements, independent horizontal scalability, and highly flexible vendor integrations.

#3 about 2 min

Empowering AI development with bounded contexts

Bounded contexts that group user interfaces, business logic, and databases form an ideal logical scope for AI coding assistants.

#4 about 1 min

Modernizing a legacy Java ERP monolithic architecture

A practical approach to successfully refactoring an aging monolithic application involves migrating functionality into strictly isolated processing domains.

#5 about 3 min

Strategies for database replication and intentional redundancy

Complex architectures maintain pure domain isolation by replicating read-only reference data through intentional database redundancy and specialized materialized views.

#6 about 1 min

Implementing event streams for real-time updates

Time-sensitive external domain actions demand broadcasting asynchronous events to instantly synchronize external states across various isolated databases.

#7 about 2 min

Defining macro-architecture and standard integration patterns

A deliberate macro-architecture supplies shared design systems, service locators, and concrete guidelines for toggling between broad database replication strategies and dedicated message brokers.

#8 about 2 min

Applying the strangler fig pattern for migrations

Incrementally replacing a monolithic codebase with bounded system modules mitigates severe deployment risks by allowing temporary parallel execution.

#9 about 3 min

Aligning engineering topology directly with business boundaries

Eliminating rigid synchronous dependencies allows substantially smaller, domain-focused engineering squads to fully retain functional context and release software autonomously.
