Object FC Access Point

If you want OSS to automatically trigger Function Compute when you initiate a GetObject request and return the transformed result of the retrieved data to the application, you must initiate the request by using an Object FC Access Point. You can make requests through Object FC Access Points to seamlessly modify or filter the content of objects without the need to change object storage semantics or modify the client.

CRR

Cross-account replication (CRR) automatically and asynchronously (in near real time) replicates object operations, such as object creation, update, and deletion, from a source bucket within an Alibaba Cloud account to a destination bucket in the same or a different region within another Alibaba Cloud account.

TLS version management

Communication between client applications and OSS is encrypted by using the transport layer security (TLS) protocol. TLS is a standard cryptographic protocol that ensures privacy and data integrity between clients and servers that communicate over the Internet. You can set a TLS version on an OSS server. After you set the TLS version, clients can use only the TLS version to send requests to and receive requests from OSS to enable secure data transfers.

Real-time access of Archive objects

Real-time access is supported for Archive objects. This feature provides real-time access to Archive objects without the need to restore them. Real-time Archive data access requires less time to retrieve data and incurs higher fees than accessing Archive data after data restoration. This feature is suitable for occasional access to extremely infrequently accessed data.

Deep Cold Archive

Deep Cold Archive provides highly durable storage at lower prices compared with Cold Archive. Deep Cold Archive has a minimum billable size of 64 KB and a minimum billable storage duration of 180 days. You must restore a Deep Cold Archive object before you can access it. The amount of time that is required to restore a Deep Cold Archive object varies based on the object size and restoration priority. You are charged data retrieval fees and API operation calling fees when you restore Deep Cold Archive objects. Deep Cold Archive is suitable for extremely cold data that must be stored for an extremely long period of time, including raw data that is accumulated over an extended period of time in the big data and AI fields, retained media resources, regulatory and compliance documents, and data that needs to be migrated from tapes to the cloud for long-term storage.

Signature tools

The following signature tools are available in the OSS console:

    After you use the signature tool to specify the parameters, the system automatically generates a request signature and verifies the request signature.

  • PostObject Policy Signature

    After you use the signature tool to specify parameters, the system automatically generates a request signature for the upload task by using an HTML form and verifies the request signature.

  • URL Signature

    You can use the signature tool to generate a signed object URL for temporary access. When you generate a signed object URL, you can specify the validity period of the URL to limit the period in which visitors can use the URL to access resources.

RTC

The Replication Time Control (RTC) feature provided by OSS can meet your compliance requirements or business requirements for cross-region replication (CRR). After the RTC feature is enabled, OSS replicates most of the objects that you uploaded to OSS within a few seconds and replicates 99.99% of objects within 10 minutes. In addition, the RTC feature provides near real-time monitoring of data replication. After you enable the RTC feature, you can view various metrics of replication tasks.

Response header adjustment for object access

The Content-Disposition: attachment header is automatically added to the response that is returned when you access an OSS object from a browser by using the default domain name of a bucket created after October 9, 2022. The browser detects the value of the response header and downloads the object as an attachment instead of providing a preview of the object. This response header is not added if you access objects by using a custom domain name.

Automatic storage tiering of OSS-HDFS

The automatic storage tiering feature of the OSS-HDFS service is available. Some data stored in the OSS-HDFS service does not need to be frequently accessed. However, due to data compliance or archiving requirements, the data still needs to be retained. To meet your business requirements, OSS-HDFS provides the automatic storage tiering feature. Data that is frequently accessed is stored as Standard objects, whereas data that is infrequently accessed is stored as Archive objects. This helps reduce the total storage cost.

Lifecycle rules based on last access time

Lifecycle rules can be configured for a bucket based on last access time in the bucket. After you configure a lifecycle rule based on the last access time for a bucket, OSS monitors the access patterns of objects in the bucket, identifies cold data, and then converts the storage class of cold data. This way, cold data is stored by using storage classes that are different from the storage classes of hot data, which helps you reduce storage costs.
