How I Reduced My Cloud Bill by 60% Without Touching My Code

Short summary

Infrastructure auditing reduced cloud costs from $340 to $136/month for 50k users by rightsizing instances (11% CPU utilization), eliminating idle databases, moving assets to object storage with CDN, and optimizing queries. No code rewrites required. Five optimizations saved $2,880/year.

• •Downsize instances based on actual CPU utilization; was paying for 4vCPU/8GB with only 11% usage, cut to 2vCPU/4GB for $80/month savings
• •Delete idle databases (he had one unused for 8 months) and migrate static assets to object storage + CDN ($105/month savings)
• •Add missing database indexes and commit to 1-year pricing for 20-40% discounts ($55/month savings)
