Cut AWS Costs by 40% — Reserved Instances Guide for Indian Companies
Indian startups and SMEs on on-demand AWS pay 40-60% more than necessary. Reserved Instances, Savings Plans, and right-sizing can slash your cloud bill immediately.
Cut AWS Costs by 40% — A Practical Guide for Indian Companies
AWS bills are a major pain point for Indian startups and SMEs. Companies running on on-demand pricing are typically paying 40-60% more than they need to. Here is how to fix that.
AWS Pricing Models Compared
| Model | Discount | Best Use Case |
|---|---|---|
| On-Demand | 0% | Dev/test environments |
| Reserved Instances (1-year) | 40% off | Steady production workloads |
| Reserved Instances (3-year) | 60% off | Core infrastructure |
| Compute Savings Plans | 66% off | Flexible instance families |
| Spot Instances | Up to 90% off | Batch jobs, fault-tolerant workloads |
Step 1: Right-Sizing — Easiest Win
Most Indian companies over-provision by default. Audit your instances in AWS Cost Explorer:
- CPU utilisation consistently below 20%? Downsize to next smaller instance
- Memory usage below 30%? Move to memory-optimised but smaller type
Typical savings from right-sizing alone: 20-30% of monthly bill.
Step 2: Reserved Instance Strategy
1. Run on-demand for 2-3 months and log baseline usage patterns
2. Purchase 1-year No-Upfront Reserved Instances for your consistently-used instance types
3. Use Convertible Reserved Instances if your instance family may change
4. Buy 3-year reservations only for truly stable, long-term infrastructure
Step 3: Storage and Database Optimisation
- S3 Lifecycle Policies: Archive data older than 90 days to Glacier — 80% cheaper
- RDS Reserved Instances: Apply the same RI strategy to databases — 40% saving
- CloudFront CDN: Offload static content from origin servers, reduce compute cost
- Delete unused resources: Unattached EBS volumes, old snapshots, idle Elastic IPs
Step 4: Auto Scaling
Set up Auto Scaling groups so infrastructure scales down during off-peak hours. Indian businesses typically have clear peak/off-peak patterns — 9 AM to 7 PM traffic, then near-zero overnight.
