  • Don’t show everythingyet. Just log in, show themaround the recipes, brewsand public recipes. Feel free to show the monitoring but no needto display the linking of sensors.
  • Show Windows Azure Web SitesShow scaling / reservedinstances
  • Show peoplearound the ACS porta. Show identities, claims andrulegroups.
  • Link a sensor to a brew. Show the effect on ACS. Show the code.
  • A couple of years ago, having a web-based application was enough. Users would navigate to it using their computer’s browser, do their dance and log out again. Nowadays, a web-based application isn’t enough anymore. People have smartphones, tablets and maybe even a refrigerator with Internet access on which applications can run. Applications or “apps”. We’re moving from the web towards apps.
  • A great example of an API is Twitter. They have a massive data store containing tweets and data related to that. They have user profiles. And a web site. And an API. Are you using www.twitter.com to post tweets? I am using the website, maybe once a year. All other tweets come either from my Windows Phone 7’s Twitter application or through www.hootsuite.com, a third-party Twitter client which provides added value in the form of statistics and scheduling. Both the app on my phone as well as the third-party service are using the Twitter API. By exposing an API, Twitter has created a rich ecosystem which drives their real value: data.
  • If you want to expose your data and services to external third-parties, you may want to think about building an API. Having an API gives you a giant advantage on the Internet nowadays. Having an API will allow your web application to reach more users. App developers will jump onto your API and build their app around it. Other websites or apps will integrate with your services by consuming your API. The only thing you have to do is expose a valuable, managed and supported API and get people to know it. Apps will come. Integration will come.
  • The mainidea of API’s is tobroadenyourreach. Youcan’tcreateappsthatcanbeused on every fridge out there, it’s way toocostly. But ifyou have a valuable service which is supported, peoplewillbuildappsaround it. Andifitmakes sense toanyonetocreate a fridge app on top of your API, itwill happen.
