AWS open source news and updates No. 34

September 7th - Instalment #34

Week No.34, and another packed issue with some great posts, projects and events covering all your favourite open source projects. This week there has been a lot of focus on Bottlerocket, which went GA last week, so plenty of stuff to read as well as several videos to watch. There are a couple of events happening later this week, so check the events just a little below and save the date in your diary.

Before you get on with the rest of this newsletter, I just want to share this event happening in a couple of weeks that I have helped shape. I would urge you to set aside some time if you can, as each of these speakers are subject matter experts in their topics.

Dev Day: Open source edition - if you haven't already done so, this is a must attend event, with four excellent sessions covering open source topics from Kubernetes networking, looking at different options on running Apache Flink, building machine learning workflows with Kubernetes and Kubeflow Pipelines and finally full-stack TypeSafety with React, GraphQL, and TypeScript. Use the link on that page to sign up and then sit back with the glow of satisfaction.

Your feedback matters!

I have put together a short feedback survey, which I would ask you to take - it will take no more than 2 minutes. You can access here. Many thanks!

There was more from Peder in this post, Five Things To Know About Bottlerocket, AWS’ New Container-Optimized Linux and the post shares some nuggets that make this a must read.

If you missed the Bottlerocket session from Kubecon AWS Container day, then here it is. Justin Haynes walks you through this project, what it is, why we created and how to get started. Twenty minutes well worth your time.

The final video is from Containers from the Couch (no, it's not a new container orchestration system) that features Justin Garrison, Brent Langston and Adam Keller also talking about Bottlerocket. Check them out here.

We then had How to Get Started with Bottlerocket OS from AWS Partner epsagon, with Ran Ribenzaft writing a nice overview post of Bottlerocket covering some use cases he sees where it might be useful.

Getting Started with Bottlerocket and Certified AWS Partners is the final Bottlerocket post, where Curtis Rissi talks about the AWS Partner opportunities that exist for using Bottlerocket for the benefit of their own customers. So read on to find out more what those opportunities are and how to get started.

Apache Hive

Amazon EMR supports Apache Hive ACID transactions - Apache Hive is an open-source data warehouse package that runs on top of an Apache Hadoop cluster. You can use Hive for batch processing and large-scale data analysis, and uses Hive Query Language (HiveQL), which is similar to SQL. In this post, Suthan Phillips and Chao Gao introduce the Hive ACID feature and explain how it works and its concepts with a straightforward use case. They go on to describe the default behaviour of Hive ACID on Amazon EMR, and offered some best practices.


Fresh from the Cloud Builders You Tube channel are a couple of videos from Steve Bryen covering a couple of the open source projects on security. If you want to know more about git-secrets and policy sentry, projects I have spoken about in the past, then these short videos are a great way to bootstrap you.
