Abstract:
Many ‘Cloud Storage’ providers have launched in the last two years, providing
internet accessible data storage and delivery in several continents that is
backed by rigourous Service Level Agreements (SLAs), guaranteeing specific performance and uptime targets.
The facilities offered by these providers is leveraged
by developers via provider-specific Web Service APIs. For content creators,
these providers have emerged as a genuine alternative to dedicated Content Delivery
Networks (CDNs) for global file storage and delivery,
as they are significantly cheaper, have comparable performance and no ongoing contract
obligations. As a result, the idea of utilising Storage Clouds as a ‘poor mans’
CDN is very enticing. However, many of these ‘Cloud Storage’ providers are
merely basic storage services, and do not offer the capabilities of a
fully-featured CDN such as intelligent replication, failover, load redirection
and load balancing. Furthermore, they can be difficult to use for
non-developers, as each service is best utilised via unique web services or
programmer APIs. In this talk we describe the design, architecture,
implementation and user-experience of MetaCDN, a
system that integrates these ‘Cloud Storage’ providers into an
unified CDN service that provides high performance, low cost, geographically
distributed content storage and delivery for content creators.
