SaaS Platform Cost Optimization
B2B SaaS Company
The Challenge
A B2B SaaS company with a monolithic Rails application was experiencing rapidly increasing infrastructure costs as they scaled. Their server bills were growing faster than revenue, and they were facing performance bottlenecks during peak hours. The legacy architecture made it difficult to scale individual components independently, and deployment times had grown to over 2 hours.
Our Approach
We conducted a comprehensive architecture audit and identified opportunities to migrate to a modern serverless architecture. Working in 2-week sprints, we incrementally migrated high-traffic API endpoints to Next.js API routes deployed on Vercel Edge Functions. We implemented infrastructure-as-code using Terraform to ensure reproducible deployments and automated scaling policies. Database queries were optimized and caching strategies were implemented using Redis.
The Outcome
The migration resulted in a 42% reduction in monthly infrastructure costs, primarily due to the serverless architecture's pay-per-use model and better resource utilization. System uptime improved to 99.9%, and deployment times dropped from 2+ hours to under 5 minutes. The new architecture automatically scales based on traffic, handling peak loads without manual intervention.
Deliverables
- Complete infrastructure migration to serverless architecture
- Terraform IaC templates for all AWS resources
- Automated CI/CD pipeline with GitHub Actions
- Comprehensive monitoring and alerting with CloudWatch
- API performance optimization (average response time reduced by 65%)
- Documentation and runbooks for operations team
Technology Stack
"Senpai Software delivered beyond our expectations. The cost savings alone paid for the project in the first 3 months, and our deployment velocity has never been better."
