Rising Costs and Reliability Issues
Drezga, a rapidly growing SaaS platform, was facing two critical challenges: skyrocketing cloud infrastructure costs and declining reliability. Their AWS bill had grown to $600K annually while uptime had dropped to 99.3%, causing customer churn.
The engineering team knew they were overprovisioned in some areas and underprovisioned in others, but lacked the data to optimize effectively. Incidents took hours to resolve because they couldn't quickly identify root causes.
Key Challenges
- Cloud costs reached $600K annually, growing 40% year-over-year
- Uptime dropped to 99.3% causing customer escalations
- Mean time to resolution averaged 2 hours per incident
- No visibility into which services consumed most resources
- Overprovisioned infrastructure in some areas, underprovisioned in others
- Slow incident response hurting customer trust
- Development team hesitant to deploy due to reliability concerns
Comprehensive Monitoring and Cost Optimization
Drezga implemented Atatus's full-stack observability platform to gain visibility into both performance and infrastructure utilization. They could now see exactly which services, features, and customers consumed the most resources.
The infrastructure monitoring revealed that 40% of their compute resources were sitting idle, while critical services were occasionally resource-starved. Error tracking and distributed tracing dramatically reduced debugging time.
Implementation Steps
- Deployed full-stack APM, infrastructure, and log monitoring
- Implemented cost attribution tracking by service and feature
- Set up resource utilization dashboards and alerts
- Configured distributed tracing across all microservices
- Created intelligent alerting to reduce MTTR
- Established performance baselines for rightsizing decisions
- Integrated monitoring data with infrastructure-as-code

Massive Cost Savings and Reliability Improvement
With Atatus insights, Drezga rightsized their infrastructure—scaling down overprovisioned resources and properly sizing critical services. This reduced cloud costs by 30% ($180K annually) while actually improving performance and reliability.
Distributed tracing and error tracking reduced MTTR from 2 hours to 18 minutes—an 85% improvement. Uptime increased to 99.95% as the team could proactively identify and fix issues. Customer satisfaction scores improved 50%.
Key Achievements
- Reduced cloud costs by 30% (saving $180K annually)
- Improved MTTR by 85% (from 2 hours to 18 minutes)
- Increased uptime from 99.3% to 99.95%
- Application performance improved 65% with optimizations
- Deployment frequency increased 3x with confidence in monitoring
- Customer satisfaction scores up 50%
- Infrastructure efficiency improved 45% with proper rightsizing
- Customer churn reduced by 40% with better reliability
"Atatus helped us solve two problems at once: we cut costs by 30% while dramatically improving reliability. The visibility into resource usage let us rightsize everything, and distributed tracing made debugging trivial. It's transformed our operations."
