AWS S3 Intelligent Tiering is an automated storage tiering feature that helps you optimize storage costs by moving data between different storage classes based on access patterns. This feature is designed to minimize storage costs while ensuring data availability and accessibility.
Data is stored in the Standard storage class by default, but with Intelligent Tiering, data is automatically moved to the Infrequent Access (IA) or Glacier storage classes when it is not frequently accessed. This reduces storage costs without compromising data availability.
Intelligent Tiering can help you save up to 50% on storage costs compared to using a single storage class. This is because data is stored in the most cost-effective storage class based on its access patterns.
The feature uses machine learning algorithms to analyze access patterns and move data to the most cost-effective storage class. This means you don't have to manually manage data storage or worry about data being moved to the wrong storage class.
What Is
AWS S3 Intelligent Tiering is a cloud-based storage class that automatically archives objects to cost-efficient storage tiers for maximum benefit. It's designed for data with unknown or changing access patterns, such as application logs, media files, and sensor data.
This storage class continuously monitors your data usage and automatically moves it between three tiers—hot, warm, and cold—based on its access patterns. The hot tier is optimized for frequently accessed data, while the warm and cold tiers are designed for infrequently and rarely accessed data.
You only pay for the storage that you consume and a small monthly fee for monitoring and automation. This means you can save money on storage costs without sacrificing performance or availability.
AWS S3 Intelligent-Tiering can be used for frequently accessed data that doesn't need the lowest latency possible, such as backups and disaster recovery files. It's also ideal for data with changing or unknown access patterns.
Here are the different storage classes in S3:
- S3 Standard: Designed for frequently accessed data.
- S3 Intelligent-Tiering: Data with changing or unknown access patterns.
- S3 Standard-IA: Designed for long-lived, infrequently accessed data.
- S3 One Zone-IA: Designed for long-lived, infrequently accessed, non-critical data.
- S3 Reduced redundancy: Frequently accessed, non-critical data.
- S3 Glacier Instant Retrieval: Designed for archive data accessed once a quarter with instant retrieval in milliseconds.
- S3 Glacier Flexible Retrieval (formerly Glacier): Designed for infrequently accessed, archived critical data.
- S3 Glacier Deep Archive: Long-term data archiving with retrieval times within 12 hours.
Customers have saved $1 billion from the introduction of S3 Intelligent Tiering in 2018 by switching from S3 Standard to S3 Intelligent Tiering.
How it Works
S3 Intelligent Tiering works by automatically moving objects between different storage tiers based on their access patterns and cost considerations.
It continuously analyzes the access patterns of stored objects, moving them from the frequent access tier to the infrequent access tier if they remain unused for 30 consecutive days.
Objects in the infrequent access tier are then automatically moved to the Archive Instant Access tier after 90 days of inactivity.
S3 Intelligent Tiering offers five storage tiers in total, each with its own criteria for data movement and performance characteristics.
Here's a breakdown of the five storage tiers:
S3 Intelligent Tiering eliminates the need for manual data management, automatically moving data between storage tiers based on access patterns and cost considerations.

Implementation and Best Practices
To implement S3 Intelligent Tiering effectively, you should consider data access patterns. This will help you determine the best storage tier for your data, which can significantly impact storage efficiency.
Data access patterns refer to how frequently and when your data is accessed. Understanding these patterns will allow you to set up lifecycle policies that optimize storage efficiency.
To optimize storage efficiency, you should set up lifecycle policies and analyze cost and access patterns. This will help you identify which data can be stored at a lower cost and which data requires faster access.
Here are some key considerations for implementing S3 Intelligent Tiering:
- Lifecycle policies: These determine when to transition data between storage tiers based on access patterns.
- Cost and access patterns: Analyze these to identify opportunities for cost optimization and storage efficiency.
- Data access patterns: Understand how frequently and when your data is accessed to determine the best storage tier.
Best Practices for Implementation
To effectively implement S3 Intelligent Tiering, consider your data access patterns. This will help you determine which data to store in which tier, ensuring optimal storage efficiency.
Understanding your data access patterns is crucial to get the most out of S3 Intelligent Tiering. This involves analyzing how frequently your data is accessed and how long it's stored.
To optimize storage efficiency, set up lifecycle policies that automatically transition data between storage tiers based on access patterns. This ensures that frequently accessed data is stored in a more expensive, but faster, tier, while less frequently accessed data is stored in a less expensive tier.
Monitoring your storage costs and access patterns is essential to optimize storage efficiency. This will help you identify areas where you can improve your storage strategy and reduce costs.
Here are some key considerations to keep in mind when implementing S3 Intelligent Tiering:
- Considerations for data access patterns, including how frequently your data is accessed and how long it's stored.
- Monitoring your storage costs and access patterns to optimize storage efficiency.
- Setting up lifecycle policies to automatically transition data between storage tiers based on access patterns.
Limitations and Considerations
If your objects have highly predictable access patterns, object lifecycle rules might be a better choice than S3 Intelligent Tiering, helping you avoid the monitoring charge associated with it.
S3 Intelligent Tiering isn't suitable for objects smaller than 128KB, as they won't be moved from the frequent access tier to the infrequent access tier.
S3 Intelligent Tiering imposes a minimum storage duration charge of 30 days, so if your objects will be deleted within this timeframe, it may not be the best option.
If your use case doesn't involve predictable access patterns, small objects, or short-lived objects, S3 Intelligent Tiering is likely a suitable choice.
