  17. 17. Goals • More efficient and flexible handling of sandboxes • Reduce cost for sandboxes • Integrate into existing environment – no new management tools – no obvious changes in behavior or functionality for endusers • Explore the capabilities of modern cloud environments Copyright 2010 Demandware, Inc. - Confidential
  18. 18. Development Decisions • Amazon EC2 32bit Instances - small / 0.08ct per hour • 1.7GB RAM / 1 virtual core • EBS Volume for persistent storage (database and user data) • CentOS 5.4 basic AMI with heavy modifications • Oracle XE - free, but with constraints • Modular concept Copyright 2010 Demandware, Inc. - Confidential
  19. 19. Cost breakdown Sandbox on POD $64 per month Cloudbox on Amazon On-Demand-Plan 0.08$ per hour Cloudbox on Amazon 1-Year-Subscripton-Plan 0.03$ per hour + 230$ per year Cloudbox on Amazon 3-Year-Subscripton-Plan 0.03$ per hour + 350$ per 3 years 60$ per month 34$ per month 25$ per month • consumption of resources on a pod – bandwidth – storage sub system – database license Copyright 2010 Demandware, Inc. - Confidential
  20. 20. What we win • Lower over-all costs • Free 20% of resources on our pods • Use those for existing customers or future ones • Being very flexible with the amount of sandboxes • No upfront investments in hardware • Easy management of CloudBoxes Copyright 2010 Demandware, Inc. - Confidential
