Krishnan S.P.T., REAN Cloud LLC


Big Data is no longer a buzz word. Public cloud is no longer the new kid in the block. The promise of elastic, reliable, inexpensive, managed services from public cloud providers has excited enterprises to store more data than ever before. More in this context refers to more of the same type of data and more granular details of the same data source. The belief was that tomorrow’s analytics software & methods will benefit from yesterday’s data. The reality however set on too soon, demanding results today to justify the cost from economic perspective. These conditions have created the perfect storm in the form of real-time big data analytics. This requires that citizen data scientists and analysts turn to managed big data services from public cloud providers instead of simply trying to recreate DIY on-premise based setup in public cloud.

In this talk, the speaker will be discussing about the various big data products from Google Cloud Platform, Amazon Web Services and DIY Big Data Stack. The focus will be on sharing the pros and cons of key products & technologies, and to which problems they are a good fit. The speaker will also provide academic lineage to some of the popular open source big data tools and the commercial products they power. Time permitting, the speaker will also conduct a demo use public data and tools from GCP and AWS.
