Two S3 Cost Optimizations You Should Always Enable: Intelligent-Tiering and Multipart Upload Cleanup
Combine S3 Intelligent-Tiering for unpredictable access patterns with lifecycle cleanup of incomplete multipart uploads to eliminate two common sources of hidden S3 costs.
Serverless Streaming to S3 with Kinesis Data Firehose and Lifecycle Archival to Glacier
Ingest 1 TB/day of IoT alerts via Kinesis Data Firehose to S3, keep 14 days for analysis, then auto-archive to Glacier — fully serverless, no infrastructure to manage.
S3 Intelligent-Tiering for Multi-AZ Resilient Storage with Unpredictable Access
Use S3 Intelligent-Tiering for data with changing access patterns that must survive AZ failures. Understand why One Zone-IA fails the resilience requirement.
Multi-Stage S3 Lifecycle: Standard to Standard-IA to Glacier with Auto-Deletion
Design a multi-stage S3 lifecycle policy that transitions data through Standard, Standard-IA, and Glacier Flexible Retrieval, then auto-deletes after a compliance retention period.
Retaining Application Logs for 10 Years: S3 Lifecycle to Glacier Deep Archive
Store 10+ TB of monthly application logs in S3, then use lifecycle policies to automatically archive to Glacier Deep Archive after 1 month for cost-effective 10-year retention.
S3 Glacier with Expedited Retrieval: Archive Storage with 5-Minute Access When You Need It
Store rarely accessed data in S3 Glacier Flexible Retrieval at minimal cost, then use expedited retrievals to get it back within 1-5 minutes for urgent requests.
Archiving Backup Files to S3 Glacier Deep Archive: The Cheapest Long-Term Storage in AWS
Configure S3 lifecycle policies to automatically move backup files from S3 Standard to Glacier Deep Archive after the active access period ends, minimizing indefinite retention costs.
S3 Lifecycle for Versioned Buckets: How to Control Non-Current Version Retention
Learn how S3 lifecycle rules with NoncurrentVersionExpiration automatically delete old object versions in versioned buckets, reducing storage costs without custom code.
Store VPC Flow Logs in S3 with Lifecycle Tiering for Cost-Effective Log Retention
Configure VPC flow logs to write directly to S3 and use lifecycle policies to transition older logs to S3 Standard-IA, balancing access speed with storage cost.
When to Use S3 Intelligent-Tiering: The Right Choice for Unpredictable Access Patterns
S3 Intelligent-Tiering automatically moves data between access tiers based on usage. Learn when it beats lifecycle policies and when it does not.
S3 Lifecycle Policy vs Intelligent-Tiering: Why Predictable Access Patterns Call for Lifecycle Rules
When your data access pattern is predictable, S3 lifecycle policies that transition to Standard-IA are cheaper and simpler than Intelligent-Tiering. Here is when to use each.
