Current cloud infrastructures are important for their ease of use and performance. However, they suffer from several shortcomings. The main problem is inefficient data mobility due to the centralization of cloud resources. The authors believe such clouds are highly unsuited for dispersed-data-intensive applications, where the data may be spread at multiple geographical locations (e.g., distributed user blogs). Instead, they propose a new cloud model called nebula: a dispersed, context-aware, and cost-effective cloud. They provide experimental evidence for the need for nebulas using a distributed blog analysis application followed by the system architecture and components of their system.
