Amazon CloudSearch is a fully managed service in the cloud that makes it easy to set up, manage, and scale a search solution. Amazon CloudSearch can search large collections of data such as web pages, document files, forum posts, or product information. CloudSearch makes it possible to search large collections of mostly textual data items called documents to quickly find the best matching results. Search requests are usually a few words of unstructured text. The returned results are ranked with the best matching, or most relevant, items listed first.

Cloudera Distribution including Apache Hadoop ( CDH ) is the most popular Hadoop distribution currently available. CDH is 100% open source. Cloudera quick start VMs include everything that is needed to tryout basic package based CDH installation. This is useful to create initial deployments for proof of concept (POC) or development.

The objective of this proof of concept project is to evaluate the feasibility of converting a traditional ETL architecture for data warehouse load into a hybrid approach with bigdata integration.   Refer the following post for architectural details.     http://www.bigdatadwbi.com/2015/08/dw-architecture-traditional-vs-bigdata.html Proof of Concept - Project Plan  The POC project has a timeline of 4 weeks. Following activities planned during this period

DW Flow Architecture - Traditional             Using ETL tools like Informatica and Reporting tools like OBIEE.   Source OLTP to Stage data load using ETL process. Load Dimensions using ETL process. Cache dimension keys. Load Facts using ETL process. Load Aggregates using ETL process. OBIEE connect to DW for reporting.
