- S3 One Zone-IA: This is a cost-effective option for infrequently accessed data that will be stored in a single Availability Zone. It is 20% cheaper than S3 Standard-IA but with reduced redundancy and is suitable for non-critical or easily reproducible data.
- S3 Glacier Instant Retrieval: It is a storage class for long-term data storage. You can preserve rarely accessed data, such as medical records or media archives, which requires fast retrieval in milliseconds.
- S3 Glacier Flexible Retrieval: This is an archive storage class that is 10% cheaper than S3 Glacier Instant Retrieval. You can use it for backups or disaster recovery of infrequently used data. The retrieval time ranges from minutes to hours, depending on the selected access speed.
- S3 Glacier Deep Archive: The S3 Glacier Deep Archive is the most cost-effective storage class of Amazon S3. It helps you retain long-term data, with retrieval required once or twice a year.
How Does Amazon S3 Work?
Amazon S3 allows you to store data as objects within buckets.
- An object is a file that consists of data itself, a unique key, and metadata, which is the information about the object.
- The bucket is the container for organizing these objects.
To store data in S3, you must first create a bucket using the Amazon Console, provide a unique bucket name, and select an AWS Region. You can also configure access controls through AWS Identity and Access Management (IAM), bucket policies, and Access Control Lists (ACLs) to ensure secure storage. S3 also supports versioning, lifecycle policies, and event notifications to help automate the management and monitoring of stored data.
Once your Amazon S3 bucket is ready, you can upload objects to it by choosing the appropriate bucket name and assigning a unique key for quick retrieval. After uploading your objects, you can now view or download them to your local PC. For better organization, you can copy objects into folders within the bucket and delete those that are no longer required.
By integrating S3 with other AWS services or third-party tools, you analyze your data and gain valuable insights.

Key Features of Amazon S3
- Replication: Using the Amazon S3 Replication, you can automatically replicate objects to multiple buckets within the same AWS region via S3 Same-Region Replication (SRR). You can also replicate data across different regions through S3 Cross-Region Replication(CRR). Besides this, the replica modification sync feature supports two-way replication between two or more buckets regardless of location.
- S3 Batch Operations: S3 Batch Operations provides a managed solution to perform large-scale storage management tasks like copying, tagging objects, and changing access controls. Whether for one-time or recurring workloads, Batch Operations lets you process tasks across billions of objects and petabytes of data with a single API request.
- Object Lock: Amazon S3 offers an Object Lock feature, which helps prevent the permanent deletion of objects during a predefined retention period. This ensures the immutability of stored data, protecting it against ransomware attacks or accidental deletion.
- Multi-Region Access Points: Multi-Region Access Points help you simplify global access to your S3 resources by providing a unified endpoint for routing request traffic among AWS regions. Such capability reduces the need for complex networking configurations with multiple endpoints.
- Storage Lens: Amazon S3 enables you to store and handle large shared datasets within multiple accounts, buckets, regions, and thousands of prefixes. You can access 60+ metrics to analyze usage patterns, detect anomalies, and identify outliers for better storage optimization.
Advantages of Amazon S3
- Enhanced Scalability: Amazon S3 provides virtually unlimited storage, scaling up to exabytes without compromising performance. S3’s fully elastic storage automatically adjusts as you add or remove data. As a result, you do not need to pre-allocate storage and pay only for the storage you actually use.
- High Availability: The unique architecture of Amazon S3 offers 99.999999999% (11 nines) data durability and 99.99% availability by default. It is supported by the strongest Service Level Agreements (SLAs) in the cloud for reliable access to your data. These features ensure consistently accessible and highly durable data.
- High-End Performance: The automated data management lifecycle of S3 facilitates efficient cost and performance balance. With resiliency, flexibility, low latency, and high throughput, S3 ensures your storage meets your workload demands without limiting performance.

Disadvantages of Amazon S3
- Regional Resource Limits: When signing up for Amazon S3, you select a storage region, typically the one closest to your location. There are default quotas (or limits) on your AWS resources on a per-region basis; some regions may have fewer resources. Such limitations could impact workloads requiring extensive resources in specific regions.
- Object Size Limitation: The minimum size for an Amazon S3 object is 0 bytes, while the maximum size is 5TB. For objects exceeding 5TB, multipart uploads are required, adding to the complexity of managing larger files.
- Latency for Distant Regions: Accessing data from regions far from your location can result in higher latency. This will impact real-time applications or workloads needing rapid data retrieval. For this, you may need to configure multi-region replication or rely on services like Amazon CloudFront for content delivery.
- Cost Management Challenges: Without proper monitoring tools, tracking resource utilization and associated costs can be complex. This may lead to unexpected expenses from data transfer, replication, or infrequent access charges.
