Industry-leading SLA	Cost-effective and easy-to-consume	Enterprise-ready security and compliance
OSS is designed for 99.9999999999% (12 9’s) durability with multi-layer redundancy and end-to-end data verification design. OSS provides high standard SLA, 99.99% availability for local redudant storage and 99.995% availability for zone redudant storage. OSS has 10+ years of history and is the storage foundation for Alibaba E-commerce platform. It passed the tests of Alibaba Double Eleven event every year and supported billions of users. And its multi-layer redundancy and end-to-end data verification design make sure it is highly durable and reliable.	OSS offers four tiers of storage: Standard, Infrequent Access, Archive, Cold Archive. Each tier is cost-optimized for specific storage pattern. The archive tier offers data retrieval time within one minute. And the cold archive tier offers expedited data retrieval time within an hour. OSS supports pay-as-you-go and different capacity reservation plans. In addition, it supports Storage Capacity Unit, which allows you to plan your all storage budget and usage in one place.	OSS makes sure your data is secure, in transit, in storage, or during access. Bring your own key (BYOK) encryption ensures your data is encrypted when it is stored in cloud platform. Write-Once-Ready-Many (WORM) prevents malicious or accidental data deletion. OSS integrates with Sensitive Data Protection to identify sensitive data, such as PII data. In addition, OSS is the only cloud storage service in China that has passed the audit and certification of Cohasset Associates and can meet specific requirements for electronic data storage.

Simple Billing

Some storage fees are hard to predict, such as API requests. A fault program can generate lots of API requests. Therefore, OSS designs a set of free quotas for the following billable items: read API requests, write API requests, internet egress.

Tranfer Acceleration

Object Storage Service (OSS) uses data centers distributed around the globe to implement transfer acceleration. When a request is sent to your bucket, it is parsed and routed to the data center where the bucket is located over the optimal network path and protocol. The transfer acceleration feature provides an optimized end-to-end acceleration solution to accessing OSS over the Internet.

Media Processing

You can add Image Processing (IMG) parameters to GetObject requests to process image objects stored in Object Storage Service (OSS). For example, you can add image watermarks to images or convert image formats.

Back to Origin

You can configure back-to-origin rules for a bucket. If a request is sent to access an object that does not exist in a bucket for which back-to-origin rules are configured, OSS obtains the requested object from the origin specified by the back-to-origin rules. You can configure mirroring-based or redirection-based back-to-origin rules for hot migration and specific request redirection.
