Explanation:
Cloud-optimized storage
Content-rich applications combined with the growth of unstructured data are challenging to
manage with traditional approach of storing data at scale. This combination of massive growth,
new information types, and the need to serve multiple locations and users around the world, has
led to requirements for information storage and management at a global scale. Cloud-optimized
storage is a solution to meet these requirements. It delivers scalable and flexible architecture that
provides rapid elasticity, global access and storage capacity ondemand.
It also addresses the constraints of rigid, mount-point based interaction between storage and
consumer by presenting a singular access point to the entire storage infrastructure. It leverages a
built-in multi-tenancy model and enables self-service, fully metered access to storage resources
thereby delivers storage-as-a-service on a shared infrastructure. Cloud-optimized storage typically
leverages object-based storage technology that uses customizable, value-driven metadata to drive
storage placement, protection and lifecycle policies.
Key characteristics of cloud-optimized storage solution are:
Massively scalable infrastructure that supports large number of objects across a globally
distributed infrastructure
Unified namespace that eliminates capacity, location, and other file system limitations
Metadata and policy-based information management capabilities that optimizes data protection,
availability and cost, based on service levels
Secure multitenancy that enables multiple applications to be securely served from the same
infrastructure.
Each application is securely partitioned and data is neither co-mingled nor accessible by other
tenants Provide access through REST and SOAP web service APIs and file-based access using
variety of client devices
