India-specific notes

S3 pricing also includes request costs (PUT, GET, etc.) and data transfer (out to internet, out to other regions). For typical Indian SMB workloads, storage cost is 70-90% of total S3 spend; requests and transfer are the remainder. Through National IT Service you get INR + GST billing, lifecycle policy design (auto-transition Standard → IA → Glacier for cost optimisation), S3 Intelligent-Tiering recommendation, and migration from on-prem storage (typical 10-100 TB migrations done via AWS Snowball / DataSync).

How to buy

WhatsApp +91 98119 98370. We assess your storage profile (active data vs archive vs backup), design lifecycle policies, migrate from on-prem, and provide ongoing cost optimisation. Typical savings vs naive S3 Standard: 40-60% via lifecycle policies + Intelligent-Tiering.

Frequently Asked Questions

For our regular use (web app uploads, daily backups), which S3 class?

Default: S3 Standard for the first 30-90 days (data is hot). Then lifecycle policy to S3 Standard-IA for 90-365 days (warm — backups, occasional access). Then S3 Glacier Flexible Retrieval beyond 1 year (cold archive). This pattern typically saves 50-70% on storage cost vs keeping everything in Standard.

How does S3 Intelligent-Tiering work?

You upload to Intelligent-Tiering class; S3 auto-moves objects between Frequent Access tier ($0.025/GB) and Infrequent Access tier ($0.0138/GB) based on actual access patterns. Pay $0.0025 / 1,000 objects/month for monitoring. Best for: unpredictable access patterns where you do not want to design lifecycle policies. Worst for: many small objects (monitoring fee adds up).

What is the cheapest way to store 100 TB of archival data?

S3 Glacier Deep Archive: $0.002/GB/month × 100,000 GB = $200/month (~₹17,000/month). For 7-year retention: ~₹14 lakh total. Alternative: AWS Backup with Glacier tier integration for compliance archives. On-premise tape libraries cost ~₹50-80 lakh upfront for similar capacity — S3 Deep Archive wins on TCO for under 500 TB archive workloads.

Data transfer out to internet — what does it cost?

First 100 GB/month: free. Next 9.99 TB: $0.1093/GB. Next 40 TB: $0.085/GB. Volume tiers continue down. For most Indian SMBs with backup/archive workloads (data goes IN much more than OUT), transfer-out is negligible. For content delivery or analytics with heavy egress, CloudFront in front of S3 typically reduces egress cost.

Can we use S3 for backup of our Indian on-premise servers?

Yes — common pattern. Use AWS Storage Gateway (file/volume/tape gateway) to provide local cache + S3 backend, or AWS Backup with on-prem agents. Lifecycle policy moves backups: hot copies in S3 Standard (last 30 days) → S3 Glacier Flexible (90 days) → S3 Glacier Deep Archive (long-term). Indian SMBs typically pay 60-80% less than equivalent on-prem backup hardware over 5-year TCO.

Free S3 cost review + lifecycle policy design — typical Indian SMBs save 40-60% on storage in first 90 days.
