The document presents a comprehensive comparison of cloud storage services provided by AWS, Azure, and Google Cloud, emphasizing their storage types, pricing, and features. It discusses block storage, object storage, and file storage alongside service availability, encryption options, and replication methods. Key differences in performance and costs are highlighted, with insightful data from the RightScale 2017 State of the Cloud report.

• Object Storage
• Hot
• Cool
• Cold (Archival)
• File Storage
• Pricing
• Why not IBM? With the combining of SoftLayer into BlueMix, we were no
longer able to find the detailed data we needed for comparison. We hope
to include them in the future.

9. • Allows dynamic modifications of:
• Volume size (increase only)
• Performance
• Volume Type
• No need to “provision for the future” initially. Volume can grow
to meet future needs
• Can increase/decrease IOPS performance to meet dynamic
or scheduled workload fluctuations
