Data indexing-AISearch

AISearch is available. AISearch allows you to quickly search for specific objects among a large number of objects based on object information conditions of documents, images, videos, and audio files, such as semantic content, multimedia metadata, and custom metadata. AISearch improves search efficiency based on object content and multimedia attributes.

OSS Connector for AI/ML

OSS Connector for AI/ML is a Python library that is used to efficiently access and store OSS data in PyTorch training jobs. You can build map-style and iterable-style datasets that are suitable for random data access and sequential streaming data access by using data in OSS. OSS Connector for AI/ML allows you to create an OssCheckpoint object. This object allows you to directly load checkpoints from OSS during model training and save checkpoints to OSS after periodic model training. This way, workflow is simplified.

Block Public Access

You can allow public access to OSS resources by configuring bucket policies and access control lists (ACLs). Public access specifies access to OSS resources without specific permissions or authentication. Public access can cause data breaches and generate a large amount of outbound traffic over the Internet due to malicious access. To prevent risks caused by public access, OSS allows you to enable Block Public Access with a few steps for OSS, a bucket, an access point, and an Object FC Access Point. If you enable Block Public Access, existing public access permissions are ignored and you cannot configure public access permissions. This disables public data access channels and ensures data security.

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 initiate requests by using 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-region replication (CRR) across accounts and same-region replication (SRR) across accounts allow the automatic and asynchronous (near real-time) replication of OSS objects from a bucket within an Alibaba Cloud account to another bucket within another Alibaba Cloud account. CRR across accounts requires that the source and destination buckets be located in different regions, and SRR across accounts requires that the source and destination buckets be located in the same region. CRR across accounts and SRR across accounts replicate operations, such as the creation, overwriting, and deletion of objects, from a source bucket to a destination bucket.

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 use an OSS server to configure the TLS version. After you configure the TLS version, clients can use only the configured TLS version to send requests to and receive requests from OSS to meet the security requirements of the communication link.

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.

Automatic storage tiering of OSS-HDFS

The automatic storage tiering feature of OSS-HDFS is available. Some data stored in OSS-HDFS 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 costs.

Lifecycle rules based on last access time

You can configure lifecycle rules based on the last access time of objects in a bucket. After you configure a lifecycle rule based on the last access time of objects, 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.
