Study on Substituting Localized Servers for Imported Servers on ETL Application

Based on a migration process of ETL applications from imported servers to localized servers environment in China Construction Bank,Xinjiang Branch,firstly,a migration solution is designed for building a comparison platform for localized servers and imported servers; Secondly, a comparison for typical types of workflows is finished under these environments, a conclusion could be drawn that banking ETL application could entirely implemented on localized server, not only from aspect of efficiency, but also from robustness.Although on localized servers,the price/performance metric of ram processing is worse than that of imported servers.
