AWS open source news and updates #64

April, 19th, 2021 - Instalment #64

Newsletter #64.

Another great selection of posts this week, starting off with the announcement last week of OpenSearch and OpenSearch Dashboards, the name of the community driven open source fork of Elasticsearch and Kibana. We have a great selection of community posts covering topics such as Apache Zeppelin, Rust, OpenJDK as well as an exciting new project called Lift to watch out for. Some great new open source projects including how to run Haskell on AWS Lambda, a nice project to make it easy to run EKS Distro on your desktop, so make sure you check those out. Finally we have some new events to put in your diary and then the usual round up of AWS open source related posts, a great podcast from Stelligent on the open source project mutato, and a video from the Seattle Java User Group taking a look at "A Journey into Latency Reduction" with Amazon Corretto. Plenty to keep you busy, but first, let's take a look at OpenSearch.


The big news of last week was the post announcing OpenSearch and OpenSearch Dashboards, the name of the community-driven, open source fork of Elasticsearch and Kibana. In the post Introducing OpenSearch, Carl Meadows, Jules Graybill, Kyle Davis, and Mehul Shah share details of this announcement, how we are working with the community and how the project is progressing.

Our goal with the OpenSearch project is to make it easy for as many people and organizations as possible to use OpenSearch in their business, their products, and their projects.

Many business are supporting OpenSearch, and are as diverse as Red Hat, SAP, Capital One, and In the post,'s response to the Elasticsearch B.V SSPL Licensing Change from Lee Smith explains how they are looking to incorporate OpenSearch and Open Search Dashboards as part of their Stack offering, just one of many business' that are looking to adopt OpenSearch.

Essential reading this week.

Open Source Job of the week

Sr. Software Development Engineer - rust-vmm

In this role, you will work on rust-vmm [1]. Rust-vmm is an open-source project that empowers the community to build custom Virtual Machine Monitors (VMMs) and hypervisors. It provides a set of virtualisation components that any project can use to quickly develop virtualisation solutions while focusing on the key differentiators of their product rather than re-implementing common components like KVM wrappers, virtio devices and other VMM libraries.The rust-vmm project is organised as a shared effort, shared ownership open-source project that includes (so far) contributors from Alibaba, AWS, Cloud Base, Crowdstrike, Intel, Google, Red Hat as well as individual contributors. It's components are already used in several projects such as Firecracker [2] and Cloud Hypervisor, [3] with more integrations under way.

wai-handler-hal from the Technology team at Bellroy lets you run Haskell (wai) Applications on AWS Lambda. WAI is the Haskell version of WSGI (Python) or Rack (Ruby): the ecosystem's standard library that describes the interface between web servers and web applications.


ssh-restricted from my colleague Adrian comes this handy AWS Config rule you can use that will check to see if any public ssh with a wide scope (i.e. and then trigger a lambda function to remediate.



open-distro-for-elasticsearch-grafana-datasource with the Open Distro for Elasticsearch plugin, you can run many types of simple or complex Elasticsearch queries to visualise logs or metrics stored in Elasticsearch. You can also annotate your graphs with log events stored in Elasticsearch. The Open Distro for Elasticsearch plugin is similar to the built-in Elasticsearch plugin, but with added support for AWS Sigv4 authentication and Piped Processing Language (PPL).


cdk-cloudfront-plus Caught this tweet from my colleague Pahud Hsieh, which was a great collaboration between a number of AWS Community Builders to build some new AWS CDK constructs covering Lambda@Edge. This is a great effort, and the constructs cover everything from security, logging and the usual suspects when it comes to working with AWS CloudFront.


This is not ready yet, but a new issue was raised in the Apache Airflow project around creating a new operator to interact with Amazon EKS. You can view the current thinking in the issue, Create EKS operators #8544 and the aim of this is to create a new Airflow operator that will:

The proposed solution is a collection of Operators, and their underlying Hooks, which will be added to the Amazon AWS provider package. These Operators will handle creating and deleting clusters, as well as executing tasks using EKS Managed Node Groups.


monkey "The Infection Monkey" is an open source security tool for testing a your resiliency to perimeter breaches and internal server infection. It is not a new open source project, but the new update last week (version 1.10.0) provides a new zero trust assessment capabilities so you can conduct zero trust assessments of your AWS environments to help identify the potential gaps in an organisation’s AWS security posture that can put data at risk. Read more on this by checking out this blog post,The Infection Monkey 1.10.0 — Go Bananas with New AWS Zero Trust Assessments from Mike Salvatore.



aws-htc-grid is an open source project that povides a reference architecture that can be used to build and adapt a modern High throughput compute solution using underlying AWS services, allowing users to submit high volumes of short and long running tasks and scaling environments dynamically.

Java, Scala, Kotlin and TLS1.0 / TLS1.1 Colm MacCárthaigh shares news that you should pay attention to if you are using OpenJDK. From April 20th the open source OpenJDK project will be releasing new versions of JDK11, JDK8, and JDK7 that remove TLS1.0 and TLS1.1 from the default list of supported TLS/SSL protocols. Colm shares for customers using Amazon Corretto that "we’re going to keep TLS1.0 and TLS1.1 in the default set for a while longer, to avoid the breaking change". This post dives deep into the issues as to why these protocols are being removed, so if you have not already planned for this, read this and be ready. As the post adds:

The OpenJDK change has been sign-posted in the OpenJDK crypto roadmap for quite a while, but breaking changes like this are still a big deal.


Improving security in s2n I missed this post from Colm MacCárthaigh's blog, shuffle sharding dot com, at the tail end of last year. The post goes into details as to the approach to reviewing security for this open source project, including the use of automation and techniques such as provable security, but crucially also the use of peer review and manual reviews. As a result, the project identified three low level issues which the posts goes on to detail.


As part of a series of posts from the Rust Foundation aimed at getting to know the board members, last week they published, Introducing Shane Miller where Shane introduces and shares her Rust story.

Quick updates


Amazon RDS for PostgreSQL now support PostgreSQL minor versions 13.2, 12.6, 11.11, 10.16, 9.6.21, and 9.5.25. This release closes security vulnerabilities in PostgreSQL and contains bug fixes and improvements done by the PostgreSQL community. This also includes the final release of PostgreSQL 9.5.

This release adds support for aws_lambda and pg_bigm. aws_lambda allows you to invoke AWS Lambda functions from an Amazon RDS for PostgreSQL DB instance. pg_bigm adds faster full text search to PostgreSQL using a bigram index.

Characters that comprise text are represented as numbers to computers. Languages such as English, French, Russian, and Hebrew use character sets of fewer than 256 characters that can be encoded in a single byte. Languages with many characters (e.g., Japanese) require more numbers, which are represented by multi-byte encoding. pg_bigm allows you to create a 2-gram (bigram) index for faster full text search of text encoded with multi-byte characters.


Amazon Elasticsearch Service now supports integrating with Microsoft Power BI, a business analytics service that delivers insights to enable fast, informed decisions. Powered by the Open Distro for Elasticsearch ODBC Driver you can now integrate your Microsoft Power BI environment with you Amazon Elasticsearch Service domains using the Open Distro for Elasticsearch SQL Engine.

The Open Distro for Elasticsearch SQL Engine uses Structured Query Language (SQL) to manifest search results in a tabular format. One of the key features of this engine is the Open Database Connectivity (ODBC) driver which enables you to integrate various business intelligence (BI) and analytics applications with Elasticsearch. You can now connect Amazon Elasticsearch Service with Microsoft PowerBI to create sophisticated and intelligent data visualisations on top of the search results obtained from Amazon ES by leveraging the Amazon ES- PowerBI Integration, to provide deep data insights.
