How to run evolution strategies on Google Kubernetes Engine

Reinforcement learning (RL) has become popular in the machine learning community as more and more people have seen its amazing performance in games, chess and robotics. In previous blog posts we’ve shown you how to run RL algorithms on AI Platform utilizing both Google’s powerful computing infrastructure and intelligently managed training service such as Bayesian hyperparameter optimization. In this blog, we introduce Evolution Strategies (ES) and show how to run ES algorithms on Google Kubernetes Engine (GKE).

Kubernetes Operators Best Practices

Kubernetes Operators are processes connecting to the master API and watching for events, typically on a limited number of resource types. When a relevant event occurs, the operator reacts and performs a specific action. This may be limited to interacting with the master API only, but will often involve performing some action on some other systems (this could be either in cluster or off cluster resources).

Four years ago, the company branched out into peer-to-peer transactions via its Cash App. After some steady growth, the app rocketed in popularity in 2016, reaching millions of users over just a few months and landing at the top of the App Store downloads.

Aria Presto: Making table scan more efficient

The Aria is a set of initiatives to dramatically increase PrestoDB efficiency. Our goal is to achieve a 2-3x decrease in CPU time for Hive queries against tables stored in ORC format. For Aria, We are pursuing improvements in three areas: table scan, repartitioning (exchange, shuffle), and hash join.

Building Lyft’s Marketing Automation Platform

We take pride in our mission to improve people’s lives with the world’s best transportation. More than 50 million carbon neutral Lyft rides happen every month across the US and Canada—and we’ve barely scratched the surface in the potential for rideshare. Part of our growth is improvements in our acquisition process—like launching region-specific ad campaigns that increase awareness, and consideration of our multi-modal offerings.

Secure Control of Egress Traffic in Istio, part 1

This is part 1 in a new series about secure control of egress traffic in Istio that I am going to publish. In this installment, I explain why you should apply egress traffic control to your cluster, the attacks involving egress traffic you want to prevent, and the requirements for your system to do so. Once you agree that you should control the egress traffic coming from your cluster, the following questions arise: What requirements does a system have for secure control of egress traffic?
