Essay
- Define cloud computing and identify the business benefits of cloud computing.
Cloud computing refers to the web-based virtual infrastructure used as a substitute for the corporate IT environment. Both software and storage are located at the service provider site and accessed using any web browser. Cloud computing as a service offers numerous business benefits. It saves a considerable amount of funding that would be otherwise necessary for the corporate system design, implementation, and maintenance (Ralph and Reynolds 310). On top of this, cloud computing provides a secure access for company’s employees from any Internet-connected PC. This feature reduces the company spending on information security.
- Discuss the use of spiders to enable user searches of the Web.
Web spiders are tools used by search engines in order to collect the information from web resources. Spiders crawl through the Internet hosts’ content primarily during the low-usage hours to avoid creating the additional load on web servers and communication lines. The collected data are stored in a form of keywords or indexes, which later participate in shaping the search results. All search queries are matched against the keywords gathered by spiders. The web search engine then sorts the results based on their relevance to the item being searched.
