  27. Cloud “Infrastructure” • Provide “Compute” and “Storage” clouds • Virtualization layers (hardware/software) • Examples: Amazon EC2, GoGrid, Amazon S3, Nirvanix, Linode • Advantages: Full control of environments and infrastructure • Disadvantages: limited competition

  28. Cloud Advantages • Lower computer costs • Improved performance • Unlimited storage capacity • Device independence • Availability

  29. Issues… • Requires a constant Internet connection • Security & Privacy • Legal Issues • Political Issues • Related Bandwidth Cost • Transparency
