Cloud Computing Is a New Technology Trend Which Changedhow Information Systems Operated and Used, While Erp Is One of the Most Usedenterprise Applications By the Market, and Considered the Core of Manycorporations. the Fact That Erp Systems Require High Resources In Term of Cost,Time and People In Order to Be Implemented and Maintained Introduced Manydifficulties For Organizations to Set Up Such a Vital System, Which Was Thedriving Force to Try to Benefit from Cloud Computing to Help Organizations Toimplement Erp Systems With Less Implementation Cost and Time. the Product Ofthis Research Was an Intersect Between the Available Relevant Knowledge, Andthe Market, Where some Market Representatives Were Interviewed to Bridge Thegap Between Theoretical and Practical Point of Views, and Get Deeper Understandingregarding Issues and Features of Erp As Cloud Service. Enterprise Resource Planning (Erp)Is Used More Than Adecade; However, the Continuing Efforts to Promote This Technology Have Beencarried Out. With Introducing Cloud Computing Technology, a Wide Variety Ofservice Can Be Implemented on Internet, Which Has a Profound Effect on Theapplication of Information Systems and Internet. Many Researches Focused Oneither Erp or Cloud Computing But Few of Them Paid Enough Attention on Theimplementation of Erp on Cloud Computing Environment. In This Paper, the Erpand Cloud Computing Are Defined As a Joint System. With the Discovery Ofdifferent Aspects of These Two Technologies, Using Thei ...
