Các Lớp Lưu Trữ đối Tượng – Amazon S3

Amazon S3 offers a range of storage classes that you can choose from based on the performance, data access, resiliency, and cost requirements of your workloads. S3 storage classes are purpose-built to provide the lowest cost storage for different access patterns. S3 storage classes are ideal for virtually any use case, including those with demanding performance needs, data lakes, data residency requirements, unknown or changing access patterns, or archival storage.

The S3 storage classes include S3 Intelligent-Tiering for automatic cost savings for data with unknown or changing access patterns, S3 Standard for frequently accessed data, S3 Express One Zone for your most frequently accessed data, S3 Standard-Infrequent Access (S3 Standard-IA) and S3 One Zone-Infrequent Access (S3 One Zone-IA) for less frequently accessed data, S3 Glacier Instant Retrieval for archive data that needs immediate access, S3 Glacier Flexible Retrieval (formerly S3 Glacier) for rarely accessed long-term data that does not require immediate access, and Amazon S3 Glacier Deep Archive (S3 Glacier Deep Archive) for long-term archive and digital preservation with retrieval in hours at the lowest cost storage in the cloud.

Amazon S3 provides the most durable storage in the cloud. Based on its unique architecture, S3 is designed to exceed 99.999999999% (11 nines) data durability. Additionally, S3 stores data redundantly across a minimum of 3 Availability Zones by default, providing built-in resilience against widespread disaster. Customers can store data in a single AZ to minimize storage cost or latency, in multiple AZs for resilience against the permanent loss of an entire data center, or in multiple AWS Regions to meet geographic resilience requirements. If you have data residency requirements that can’t be met by an existing AWS Region, you can use S3 storage classes for AWS Dedicated Local Zones or S3 on Outposts racks to store your data in a specific data perimeter.

You can configure S3 storage classes at the object level, and a single general purpose bucket can contain objects stored across all storage classes except S3 Express One Zone. Amazon S3 also offers capabilities to manage your data throughout its lifecycle. Once an S3 Lifecycle policy is set, your data will automatically transfer to a different storage class without any changes to your application. S3 directory buckets only allow objects stored in the S3 Express One Zone storage class, which provides faster data processing within a single Availability Zone, and do not support S3 Lifecycle transitions.
