IBM Cloud® Object Storage is software-defined data storage as a managed service on IBM Cloud®. It's an alternative to block and file storage and also available for on-premises deployment in your private cloud.

With its global presence and flexible resiliency options, IBM Cloud Object Storage is a storage service for any kind of unstructured data in any format. It's designed for high durability, resiliency and security. Information stored in IBM Cloud Object Storage is encrypted and dispersed across multiple geographic locations using IBM distributed storage technologies. 

IBM Cloud Object Storage supports exponential data growth for your cloud-native workloads with best-in-class cost optimization, robust data security and data governance with ease of use. Built-in data lifecycle operations also make it easy to observe and manage your critical workloads.

Store any kind of data, such as images, videos and documents in any format. The total volume of data you can store is virtually unlimited. Individual objects can range in size, with maximum size of 10 TB. For objects larger than 100 MB, consider uploading objects in multiple parts. Access your data using SDKs or the IBM user interface.
