Why Choose MicrocosmWorks for System Re-Architecture?
Sometimes incremental improvements aren't enough — the fundamental architecture needs to change. We specialize in redesigning systems that have outgrown their original constraints: single-server apps that need horizontal scaling, synchronous systems that need event-driven architecture, or tightly-coupled systems that need modular design.
Our Re-Architecture Capabilities
- Architecture Assessment — Deep analysis of current system constraints, bottlenecks, scaling limits, and the gap between current state and business requirements.
- Target Architecture Design — Design the future-state architecture with clear rationale for every decision, technology choice, and tradeoff.
- Migration Path Planning — Plan the safest path from current to target architecture, identifying phases, risks, and rollback strategies for each step.
- Event-Driven Transformation — Redesign request-reply systems into event-driven architectures for better scalability, resilience, and decoupling.
- Multi-Region Design — Architect for global deployment with data locality, consistency models, and failover strategies for high availability.
- Performance Architecture — Design caching strategies, read/write separation, async processing, and resource optimization for target performance goals.
Technology Stack
We design with modern, proven technologies: Kubernetes for orchestration, Kafka for event streaming, PostgreSQL with read replicas for data, Redis for caching, and cloud-native services for managed operations. All decisions are documented in Architecture Decision Records with clear rationale.
Who This Is For
Companies whose systems are hitting fundamental architectural limits — can't scale further, can't add features without breaking things, or can't meet reliability requirements. If your architecture was designed for a different era of your business, it's time to re-architect for what's next.
Our Process
1
Architecture Assessment
Deep dive into current system — identify limits, bottlenecks, scaling ceilings, and architectural constraints.
2
Target Architecture
Design future-state architecture with ADRs for every major decision. Model for 10x current scale.
3
Migration Strategy
Plan phased migration path with clear milestones, risk mitigation, and rollback capabilities per phase.
4
Execution
Execute re-architecture in phases, validating each transition before proceeding to the next.
5
Validation & Optimization
Load test new architecture, validate against requirements, optimize performance, and document operations.

Frequently Asked Questions
Re-architecture is warranted when the current architecture fundamentally cannot meet scaling, performance, or reliability requirements, when the cost of workarounds exceeds the cost of re-architecture, or when critical technology is end-of-life. MicrocosmWorks helps you make this decision with data.
System re-architecture consulting and implementation at MicrocosmWorks ranges from $30-$50/hour. We provide a detailed assessment and phased roadmap before committing to implementation so you understand the full investment.
Yes, we use parallel-run strategies where the new architecture is built alongside the existing system, with traffic gradually shifted using feature flags and canary routing. This ensures zero downtime and the ability to roll back at any point.
We define performance benchmarks upfront, implement load testing throughout development, run production-representative stress tests, and perform shadow traffic testing to compare new architecture performance against the existing system before cutover.
Yes, we deliver comprehensive architecture decision records (ADRs), system diagrams, runbooks, and conduct knowledge transfer sessions to ensure your team fully understands and can maintain the new architecture independently.
