How Amazon is solving big-data challenges with data lakes

"(...) A major reason companies choose to create data lakes is to break down data silos. Having pockets of data in different places, controlled by different groups, inherently obscures data. This often happens when a company grows fast and/or acquires new businesses. In the case of Amazon, it's been both (...)" (Werner Vogels)

Leitura Recomendada: "Factfulness: Ten Reasons We're Wrong about the World"

"I don’t love numbers. I am a huge, huge fan of data, but I don’t love it. It has its limits. I love data only when it helps me to understand the reality behind the numbers, i.e., people’s lives. In my research, I have needed the data to test my hypotheses, but the hypotheses themselves often emerged from talking to, listening to, and observing people. Though we absolutely need numbers to understand the world, we should be highly skeptical about conclusions derived purely from number crunching."

Machine Learning for Everyone

(...) Without all the AI-bullshit, the only goal of machine learning is to predict results based on incoming data. That's it. All ML tasks can be represented this way, or it's not an ML problem from the beginning. The greater variety in the samples you have, the easier it is to find relevant patterns and predict the result (...)

AWS, Microsoft or Google: Which cloud computing giant is growing the fastest?

"Spending on cloud computing infrastructure continues to grow at a furious pace, but cloud vendors will have to work harder for their profits from now on. Global cloud infrastructure services market grew 42 percent year-on-year in the first quarter of 2019 with Amazon Web Services (AWS) making the biggest gain in dollar terms with sales up by $2.3 billion (41%) on Q1 2018, according to data from tech analyst firm Canalys.

How to Move Beyond a Monolithic Data Lake to a Distributed Data Mesh (Martin Fowler)

Many enterprises are investing in their next generation data lake, with the hope of democratizing data at scale to provide business insights and ultimately make automated intelligent decisions. Data platforms based on the data lake architecture have common failure modes that lead to unfulfilled promises at scale. To address these failure modes we need to shift from the centralized paradigm of a lake, or its predecessor data warehouse. We need to shift to a paradigm that draws from modern distributed architecture: considering domains as the first class concern, applying platform thinking to create self-serve data infrastructure, and treating data as a product. (...)

Can You Be a Great Leader Without Technical Expertise? (Harvard Business Review)

"There is a broad assumption in society and in education that the skills you need to be a leader are more or less transferable... But recent research is rightly challenging this notion. Studies suggest that the best leaders know a lot about the domain in which they are leading, and part of what makes them successful in a management role is technical competence. For example, hospitals managed by doctors perform better than those managed by people with other backgrounds. And there are many examples of people who ran one company effectively and had trouble transferring their skills to the new organization(...) "
