Link analysis in web vs cloud
Short answer
Web link analysis uses hyperlinks between pages for ranking and community detection; cloud link analysis processes large graphs on distributed platforms like MapReduce, or analyzes links among cloud resources. Cloud offers on-demand scalability and lower cost, but introduces privacy and bandwidth concerns.
Compare Link analysis in web Vs Link analysis in cloud.
Link analysis studies relationships (links) between entities to find importance and structure. On the web the entities are pages and hyperlinks; in the cloud the same graph techniques run on cloud platforms, or are applied to links among cloud resources, users and data.
| Basis | Link analysis in the web | Link analysis in the cloud |
|---|---|---|
| Data | Hyperlinks between web pages | Large link/graph data (web graph, social graph, call or access links) stored and processed on cloud, or links between cloud services, users and data |
| Purpose | Rank pages, find communities, detect spam | Run the same analysis at scale; also trace dependencies, detect fraud or insider threats and track data flow |
| Scale | Limited by one organisation's machines, usually crawled data | Scales on demand using many virtual machines; works on very large graphs |
| Processing | A centralised or cluster system | Distributed processing (MapReduce, Hadoop, Spark/Pregel) in a pay-per-use model |
| Cost | High capital cost for own infrastructure | Pay as you use, less cost for occasional jobs |
| Examples | PageRank, HITS | PageRank computed with MapReduce on cloud; link analysis of cloud logs for security |
| Issues | Link spam, freshness | Data security and privacy, network bandwidth, vendor lock-in |
