  • 1. Cloud Storage Providers Comparative Study Dayanand Shanmugham http://www.linkedin.com/in/dayanandshanmugham http://dkangala.wordpress.com January 2013
  • 2. Comparative Study (Done by Nasuni) http://www.nasuni.com/downloads/resources/87/the_state_of_cloud_storage.pdfBackground:1. In April 2009, Nasuni began an ongoing and unprecedented evaluation process of “Cloud Service Providers (CSPs)” based on a wide array of factors2. Technical test looked at how CSPs perform in a specific use case, namely, how they perform for organizations that want to take advantage of the cloud for primary storage, data protection and disaster recovery. Nasuni did not test for every possible use case.3. Test focus on three key areas of importance for organizations that want to take advantage of cloud storage: – Performance: The cloud needs to respond quickly to queries and not slow when stressed. If performance is poor, organizations will spend too much time waiting on the cloud and productivity will suffer. – Stability/Availability: If organizations are to trust critical data to the cloud, it must be available at all times. – Scalability: One of the primary advantages of cloud storage is unlimited capacity. Without this property, the cloud is much less valuable to organizations.
  • 3. Comparative Study Results http://www.nasuni.com/downloads/resources/87/the_state_of_cloud_storage.pdfResults:1. Ultimately, only 6 of 16 providers passed Nasuni’s testing: – Amazon S3 – AT&T Synaptic Storage as a Service – Microsoft Azure – Nirvanix – Peer1 Hosting – Rackspace Cloud1. Only Two Cloud Service Providers emerged as top performers in the Nasuni study: – Amazon S3 – Microsoft Azure (Note: Amazon S3 standout across all evaluation areas)
  • 4. Comparative Study Methodology http://www.nasuni.com/downloads/resources/87/the_state_of_cloud_storage.pdfMethodology:1. API Integration – To ensure that it is possible to test the service at all2. Unit Testing – Larger software components are broken down into their building blocks (units) and then tested for inputs, outputs and error cases3. Performance Testing – To measure response time (how quickly one can interact with the cloud), throughput (how fast data can move back and forth to and from the cloud), and the impact of a higher level of stress.4. Stability Testing – To assess the long-term reliability of each CSP5. Scalability Testing – To understand how well each CSP handles high object counts
