Monolith to Microservices Migration
Strategically decompose a monolithic application into microservices to improve scalability, enable team autonomy, and accelerate development. Expert guidance on service boundaries, data management, and migration approach.
Why You Need This Service
Monoliths eventually become bottlenecks - hard to scale, slow to deploy, and limiting team productivity. But premature or poorly executed microservices create complexity nightmares. Expert guidance ensures you migrate for the right reasons with the right approach.

Investment
Fractional C T O
$10,000-$15,000/month for 12-18 months
Implementation
$150,000-$500,000 for team and development
Infrastructure
$5,000-$20,000/month additional costs
Total
$300,000-$800,000 complete program
Expected ROI
Enable independent team scaling, faster deployment, better reliability
Success Story
Series C SaaS platform, monolithic Ruby on Rails app, 50 engineers
Challenge
Deployment taking 4+ hours with frequent rollbacks. Can't scale background jobs independently from web servers. Team growth stalling as developers step on each other. Specific features needed to scale differently but can't.
Solution
Fractional CTO led domain-driven design exercise identifying 8 major service boundaries. Implemented event-driven architecture using Kafka. Extracted services one at a time starting with most independent. Built comprehensive observability. Reorganized teams around services.
Results
Deployment time reduced from 4 hours to 15 minutes per service. Background job processing scaled independently, handling 100x more volume. 5 teams deploying independently multiple times per day. Feature velocity increased 60%. Successfully scaled to 120 engineers.
Timeline: 14 months for complete migration
