Cloud Storage Overview
Cloud Storage, also known as object storage, is a requisite cornerstone of today's Internet scale applications. It's an evolution of traditional block and file based storage systems with services based, distributed, redundant, commodity principles of the cloud applied. Cloud storage is used for Storage as a Service (StaaS) and as the secondary storage for cloud compute platforms. It is the bedrock of Amazon-style clouds because Cloud Storage provides the common API set enabling hybrid cloud migration, acts as the recovery mechanism for cloud compute platforms, and is much more cost effective, simpler to use, and is highly scalable.
- Common S3 API provides for all apps and tools in the ecosystem, allows hybrid cloud migration
- Acts as recover mechanism for Amazon-style clouds
- Better than file-based systems less cost, simpler, more scalable
As with all services based architectures, cloud storage decouples the data stored from the applications and users consuming it. Objects (or files with associated metadata) are stored in single namespace buckets versus nested folder hierarchies and are available using internet standard HTTP calls. As a result, cloud storage systems are extremely scalable, high performance and highly available.
Amazon popularized cloud storage in 2006 with the introduction of S3, Amazon's first publicly available web service. The consumption of cloud storage has been accelerating ever since, as application developers and users take advantage of cloud storage's accessibility, reliability and low cost. With over 1 trillion objects now stored in the hosted S3 service, the AWS S3 API is the de facto standard for cloud storage.
Cloudian is ideal for enterprises and service providers looking to offer Amazon S3-compatible Storage as a Service (StaaS) and/or provide secondary storage systems for their cloud compute platforms, such as Citrix Cloud Platform, Apache CloudStack, or OpenStack. By introducing the Cloudian Community Edition, which will support up to 100 TB of useable storage and offer forum support, Cloudian is opening up the scalability, reliability and power of cloud object storage to anyone building an Amazon S3-compatible cloud, be it public, private or hybrid. Cloudian is also available with Gold and Silver support packages.
