Amandeep Kaur Project for Chapter 14 Choose either Option A or Option B to submit through Class Moodle site editor Option A InterContinental Hotels Group (IHG) is an international hotel company that operates over 4,000 hotels in 100 countries under seven brands, including Holiday Inn and InterContinental. It is also the largest Western supplier of hotel rooms in China. IHG uses several types of cloud computing platforms to improve the efficiency and effectiveness of its operations. In addition to cost savings, the company says, it moved into cloud computing because it wanted a faster and more flexible way of getting a new system up and running, and because of the cloud's ease of integrating various applications under a single platform. According to Bryson Koehler, IHG's senior vice president of revenue and guest information, the savings also comes in other ways, "such as improved flexibility and the ability to deliver a more tailored experience to end users." IHG is building a private cloud for its CRM applications using Salesforce.com's CRM. It is also building a private cloud called Camelot for its loyalty program. Camelot performs several major tasks. First, it analyzes current guest activity and maintains historical records for future use. Second, it is used for promotions tailored to individual guests. Third, it runs revenue management and room-yield operations, from which room rates are calculated. The public cloud at IHG is used for application development and testing. This includes steps similar to the systems development life cycle (SDLC) discussed in Module 10. The platform chosen for this operation is Amazon Web Services' Elastic Compute Cloud infrastructure.
