BigData UseCases● Google Index
● 40 X 10^9 = 40.000.000.000 => 40 billion pages indexed● Will break 100 PB barrier soon● Derived from MapReduce● now “caffeine” based on “percolator”
● Incremental vs. batch● In-Memory vs. disk

BigData UseCases● CERN LHC
● 25 petabytes per year● Facebook
● Hive Datawarehouse● 300 PB, growing 600 TB / d● > 100 k servers
● Genomics● Enterprises
● Data center analytics (Logflies, OS/NW monitors, ...)● Predictive Maintenance, Cybersecurity
● Social Media Analytics● DWH offload● Call Detail Record (CDR) data preservation

Google AppEngine
Google App Engine is a Platform as a Service (PaaS) offering that lets you build and run applications on Google’s infrastructure. App Engine applications are easy to build, easy to maintain, and easy to scale as your traffic and data storage needs change. With App Engine, there are no servers for you to maintain. You simply upload your application and it’s ready to go.
