Teeboxer uses Twilio as a cloud-based communication platform to help golfers play more and spend less time dealing with their game off the course. Teeboxer's web application runs on Rackspace Cloud, while Twilio is hosted in Amazon's EC2. When users call or text Teeboxer, they are actually interacting with Twilio, which makes a web request to Teeboxer and receives instructions via TwiML markup language. This interaction enables Teeboxer to provide personalized services such as verifying user information, determining local time, and sending texts with links to golf course maps. By leveraging Twilio's cloud-based communication capabilities, Teeboxer is able to offer its users a seamless and engaging experience that combines multiple Internet technologies.
