The Challenge

A fast-growing e-commerce company came to ZenoCloud with a common problem: their AWS bills were spiraling out of control. Despite their best efforts to optimize, they were spending over $15,000 per month on infrastructure, and costs were growing faster than their revenue.

Key Pain Points

  • Unpredictable monthly AWS costs with frequent overages
  • Oversized EC2 instances running 24/7
  • No clear visibility into cost allocation
  • Performance issues during peak traffic despite high spending

The Solution

Our team conducted a comprehensive AWS infrastructure audit and implemented a multi-pronged optimization strategy:

1. Right-Sizing Instances

We analyzed CPU, memory, and network utilization across all instances and found that 60% were oversized. By right-sizing to appropriate instance types, we achieved immediate savings without impacting performance.

2. Reserved Instances & Savings Plans

For predictable workloads, we implemented a mix of Reserved Instances and Savings Plans, securing discounts of up to 72% compared to on-demand pricing.

3. Auto-Scaling Implementation

We configured intelligent auto-scaling that automatically adjusts capacity based on actual demand, eliminating the need for over-provisioning.

4. Storage Optimization

  • Implemented S3 lifecycle policies to move old data to cheaper storage tiers
  • Cleaned up unused EBS volumes and snapshots
  • Optimized database storage with proper indexing

5. CDN & Caching

By implementing CloudFront CDN and ElastiCache, we reduced origin server load by 70%, decreasing compute costs while improving response times.

The Results

40% Cost Reduction
2x Performance Improvement
99.99% Uptime Achieved

Monthly Savings Breakdown

  • EC2 Optimization: $2,500/month saved
  • Reserved Instances: $2,000/month saved
  • Storage Cleanup: $800/month saved
  • Data Transfer: $700/month saved

Client Testimonial

"ZenoCloud didn't just cut our costs—they transformed how we think about cloud infrastructure. We're now spending less while handling twice the traffic, and our team can focus on building features instead of managing servers." — CTO, E-commerce Company

Key Takeaways

  • Regular infrastructure audits are essential for cost control
  • Right-sizing is often the quickest path to savings
  • Combining multiple optimization strategies yields the best results
  • Improved architecture often delivers both cost savings and better performance
