Working examples of Lambda Architecture

Here are some of the working examples where Lambda Architecture has been used as a way by which certain use cases have been handled:

• Multiple use cases on Twitter: One of the use cases where modified lambda is used in the area of sentiment analysis of tweets.
• Multiple use cases in Groupon.
• Answers by Crashlytics: Deals with mobile analytics, use Lambda Architecture layers of batch and speed effectively to produce meaningful analytics.
• Stack Overflow: A well-known question-answer forum with a huge user community and plenty of activity. For a logged-in user, recommended questions make a new section, where the Lambda Architecture is used. There are other analytics too, such as voting, which uses batch views.
• Flickr Magic View: Revised Lambda Architecture to create a magic view by combining bulk and real-time compute (courtesy: code.flickr.com).
