Recordings: Data Security Webinar Series for Protegrity

A couple of posts back I shared a sneak-peak of my webinar on data security for data monetization initiatives. That was one of many sessions we’ve ran for APAC as Protegrity entered that market in 2018. All sessions had been recorded and now I’m happy to say we’ve published excerpts of those videos on youtube. There are bits on Big Data protection, best security practices for analytical workflows, sessions on hybrid- and multi-cloud environments, as well as spotlights on specific technologies (AWS S3, OneDrive, Salesforce, Elastic Map Reduce, Tableau). The videos are 2- to 7-minute-long and go straight to the demo. I do sympathise with those of you that don’t have the time or patience to sit through a one hour webinar – I hope you like this compact format. Check out the playlist below and get to know the superpowers of Protegrity tech!

Recording: Introduction to Hadoop for Glolent community meetup

Last Thursday evening I had the opportunity to talk about Hadoop at a Glolent Global Talent community virtual meetup. Glolent connects remote IT workers across the globe and facilitates skill-sharing sessions that any member can join or present at. I rarely demonstrate Hadoop anymore so I needed to take a couple of evenings to brush up on the fundamentals. The talk is a distilled product of that study. I approached Hadoop’s architecture from a historical perspective: I started the talk by introducing the root problem – I/O bottleneck in processing Big Data – and positioned Hadoop Distributed File System as its panacea. There was an obligatory intro to the original processing paradigm on Hadoop: MapReduce, and a classic word count example of Shakespeare’s collected works. That was followed by a review of programming abstractions built on MapReduce and some alternative processing engines to MR – with an emphasis on Spark. A 30-minutes talking slot is very little time so I had to cut out any mention of resource or cluster management. You can judge for yourself how it turned out – I shared the recording below.
