The Problem
Early-stage biotech startups often over-provision AWS infrastructure as a precaution, then watch costs compound as the team grows. ImmunisAI had accumulated orphaned EC2 instances, over-sized RDS clusters, and multi-region redundancy that served no production purpose. Their monthly AWS bill had tripled in 12 months without proportional growth in traffic or users, a pattern common in fast-moving teams that prioritize shipping over infrastructure hygiene.
How We Solved It
We ran a full audit using AWS Cost Explorer, Trusted Advisor, and Compute Optimizer, mapping every dollar of spend to its source. From there: right-sized 8 EC2 instances to appropriate families and sizes, converted 3 on-demand RDS instances to 1-year reserved capacity, eliminated 4 idle Elastic IPs and associated NAT gateway charges, and collapsed an unnecessary multi-region architecture generating avoidable cross-region data transfer costs. All changes were executed live using blue/green swap patterns and RDS parameter group updates. Zero downtime across a two-month systematic optimization cycle.
What We Delivered
- 30% reduction in monthly AWS costs
- Completed in just 2 months
- Zero downtime during optimization
