I spent 8 months at Microsoft team and also 8 months at the IT Security. I worked with several MS products and with DLP solutions.
I created a skeleton for an idea. Hosting an app with round robin dns with IIS with Apache Cassandra and Zookeeper for transactions. In the project I used also Neo4j graph database for geolocation calculations.
I built this sandbox for pig, hbase and hive testing mainly but now I moving on for using Spark features. Its based on Cludera's CDH5 distribution and running on 3 PC and 1 server. Cassandra used for storing logs what can be processed with Pig. Another testing scerenio was creating 2 cassandra ring one for heavy load and an other for analytics. Now this sandbox good for testing R with Hadoop(SparkR and Spark MLlib).
This project is about how can you do autoscale(Scale up and down) over Amazon AWS. I use Chef for spinning up an infrastructure and Python to coding the ML and control Chef.
