This phrase is new and it originated at Netflix back in 2010. I was listening to Nora Jones, a Netflix engineer at the AWS re-Invent conference few weeks back, where she talked about this. The principle of Chaos goes like this, “Chaos Engineering is the discipline of experimenting on a distributed system in order to build confidence in the system’s capability to withstand turbulent conditions in production.” Distributed systems have too many moving parts and failures can occur at various levels – hard disks can fail, the network can go down, a sudden surge in customer traffic can overload a functional component—the list goes on. All too often, these events trigger outages, poor performance, and other undesirable behaviors. Chaos Engineering is a method of experimentation on infrastructure that brings systemic weaknesses to light. This empirical process of verificati... (more)

Big Data and Analytics – What’s Ahead? | @ThingsExpo #IoT #M2M #BigData

Recently I read somewhere this statement – As we end 2017 and look ahead to 2018, topics that are top of mind for data professionals are the growing range of data management mandates, including the EU’s new General Data Protection Regulation that is directed at personal data and privacy, the growing role of artificial intelligence (AI) and machine learning in enterprise applications, the need for better security in light of the onslaught of hacking cases, and the ability to leverage the expanding Internet of Things. Here are the key areas as we look ahead: Business owners deman... (more)

Dell + (EMC+VMW) = A $67B Gamble | @CloudExpo #BigData #Microservices

Yesterday, Dell announced the largest technology M&A in history with a proposed $67B buyout of EMC and VMware (via EMC’s 80% ownership of VMW). The combined company will have over $80B in revenue, employ tens of thousands of people around the world and sell everything from PCs, servers & storage to security software and virtualization software. Not to be overlooked is the fact that Dell and EMC will be private companies and free from the scrutiny of activist investors. Dell has to borrow a ton of money to make this deal, like $40B debt. The annual interest payment will be $2.5B!... (more)

Introducing Big Data

The phrase “Big Data” is thrown around a lot these days. What exactly is referred to by this phrase? When I was part of IBM’s DB2 development team, the largest size limit of a DB2 Table was 64 Gigabytes (GB) and I thought who on earth can use this size of a database. Thirty years later, that number looks so small. Now you can buy a 1 Terabyte external drive for less than $100. Let us start with a level set on the unit of storage. In multiples of 1000, we go from Byte – Kilobyte (KB) – Megabyte (MB) – Gigabyte (GB) – Terabyte (TB) – Petabyte (PB) – Exabyte (EB) – Zettabyte (ZB) –... (more)

India 2.0: Innovation in India Happening More Slowly Than Anticipated

I just spent 3 days in Bangalore for a board meeting. Staying in south Bangalore around JP Nagar and Jayanagar area feels like the old Bangalore of yesteryears – greenery all around, spring flowers, no high rise apartment buildings, and comparatively more tranquil ambiance. Once I went to north, around Whitefield area, the new Bangalore intimidates you – huge apartment complexes, no trees, chaotic traffic and what not. All over town, one notices the construction of the new metro – the overhangs spoil the beauty of the city. Of course the area around electronic city is all concret... (more)
