software design and archtrctire

Google is a company that famously uses big data. In addition to having access to user information through its Chrome browser and Gmail products, Google also receives billions of search requests every day on its search engine. Your company manager requested you to prepare an estimate for a system within two weeks that collects users search information and keeps historical records for individual google users to recommend commercial products and many other products and services based on the nature and content of their historical searches. Such an application must be up and running 24/7. Whenever possible, it is recommended to use open-source products and google technologies to cut down on costs.

List and describe suitable architectural drivers for such an application keeping in mind all critical issues such a system would require?

Discuss the design goal and possible design concepts for the first iteration? Explain how you would achieve your manager's request and recommendations to provide a complete estimate that includes all necessary information?
