The Cloud Bill Shock
Most companies experience cloud bill shock at some point. Infrastructure costs that seemed reasonable at 1,000 users become unmanageable at 100,000. The good news: the majority of cloud waste is preventable with the right architectural decisions.
Rightsizing Compute
The most immediate opportunity is rightsizing. Cloud providers give you incredible flexibility in instance sizes, but most teams set-and-forget. Run your compute at 15-20% average CPU utilization? You're almost certainly over-provisioned.
**Action:** Enable AWS Compute Optimizer or Azure Advisor. Implement automated rightsizing recommendations on a monthly review cycle.
Reserved Instances and Savings Plans
On-demand pricing is a premium for flexibility. If you have predictable baseline workloads, commit to Reserved Instances or Savings Plans. You can realistically achieve 40-65% savings on compute.
**Action:** Analyze your 90-day utilization baseline. Reserve everything that runs 24/7. Keep on-demand only for burst capacity.
Database Optimization
Databases are often the single largest line item in cloud bills. Key levers:
Response Compression
This one is underrated. Enabling Brotli compression on your API responses can reduce bandwidth costs by 70-80%. For mobile-heavy applications where bandwidth is a real user experience concern, this also improves perceived performance.
The 80/20 of Cloud Optimization
Focus your optimization effort on: compute rightsizing, Reserved Instances, and database efficiency. These three categories typically account for 70-80% of cloud spend. Everything else is incremental improvement.
