Latest open source projects


ottr this is the latest open source project from Airbnb engineering, Ottr. Ottr is a serverless Public Key Infrastructure framework that handles end-to-end certificate rotations without the use of an agent. You can check out the super detailed blog post, Meet Ottr: A Serverless Public Key Infrastructure Framework from Kenneth Yang provides an overview on Ottr with details of the architecture, logical and network flows and details on how to deploy.



cloudkey this project from Aidan Steele is perfect if you have a Yubikey and want to use it to assume IAM roles to interact with AWS. As Aidan says:

"I could create certificates on the Yubikey, enrol them into AWS IoT (for free) and assume roles in AWS with no IAM secret access keys stored on disk."

Worth checking out Aidan's thread on twitter, here for more context.


clock-bound this new project provides you with a consistent, trusted time service will allow you to compare timestamps to determine order and consistency for events and transactions, independent from the instances’ respective geographic locations.



aws-recon this project from Darkbit is a multi-threaded AWS security-focused inventory collection tool written in Ruby, and was created to facilitate efficient collection of a large amount of AWS resource attributes and metadata. It aims to collect nearly everything that is relevant to the security configuration and posture of an AWS environment. It is being used by some interesting customers, so well worth checking this out.


cdk-dia this project from Tom Roshko looks super neat, it diagrams your CDK provisioned infrastructure using the Graphviz dot language. After getting Graphviz running on my Macbook (thanks Mac Ports) I tried it on one of my projects, and here is the output. What do you think? A great start, so it will be interesting to see how this project evolves and develops. Nice work Tom!



aws-cdk-github-oidc is a CDK constructs to use OpenID Connect for authenticating your Github Action workflow with AWS IAM. These constructs allows you to harden your AWS deployment security by removing the need to create long-term access keys for Github Actions and instead use OpenID Connect to Authenticate your Github Action workflow with AWS IAM.


You can check out last weeks newsletter where Richard Boyd shows you using this new capability of GitHub Actions.


fiware-orion-on-aws FIWARE is a curated framework of open source platform components to help with the development of smart applications and solutions. This repository is a reference implementation of one of those components, the Orion Context Broker which uses another component in that project, Cygnus. To help you get started, check out the blog post How to build smart cities with FIWARE Orion Context Broker and Cygnus on AWSfrom Masahiro Imai, Hidenori Koizumi, and Jorge Lanzarotti


Retro corner

Thanks to Corey Quin for highlighting this tool I had missed.


aws-key-disabler this open source project is a small lambda script that will disable access keys older than a given amount of days. Small but perfectly formed, I think this is a great solution if you find yourself needing to automate the vending of your keys.

Tweet of the week

This tweet from Christos Matskas (@christosmatskas) came up on my timeline last week, where he shared how he was able to use the open sourced NodeJS library for verifying JWTs that I shared in the last episode, and verify AAD access tokens from Azure Active Directory. He also shared the code, which you can check out at here. Christos also put this post together, Open Standards, Security, Azure AD and AWS which shows you the end to end story. Nice!

AWS and Community blog posts


Building Software as a Service (SaaS) is an increasingly popular approach for open source projects to provide customers with immediate access to their capabilities. There are several approaches you can take, but being able to well and ensure a good experience during on boarding, you need to have a reliable, fast, and multi-region capable provisioning and software lifecycle management. In the post, Parallel and dynamic SaaS deployments with AWS CDK Pipelines Jani Muuriaisniemi and Jose Juhala describe a deployment system for achieving this using AWS CDK and AWS CDK Pipelines. [hands on]



I shared details of BayerCLAW in a previous newsletter (#86). BayerCLAW a workflow orchestration system for AWS, targeted at bioinformatics pipelines. Jack Tabaska and Ian Davis from the Bayer Crop Sciences team have put together this blog post, BayerCLAW – Open-Source, Serverless Orchestrator for Scientific Workflows on AWS that takes a look at the motivations and technical implementation of BayerCLAW.



AlphaFold is an artificial intelligence program developed by Alphabets's/Google's DeepMind which performs predictions of protein structure. In this post, Run AlphaFold v2.0 on Amazon EC2, Qi Wang provides a step-by-step guide on how to install AlphaFold on an EC2 instance with Nvidia GPU.

GitHub Actions

Frank Dallezotte and Maxwell Moon have collaborated on this post, Building ARM64 applications on AWS Graviton2 using the AWS CDK and Self-Hosted Runners for GitHub Actions where they show how to configure of a self-hosted GitHub Runner on an EC2 instance with a Graviton2 processor, the required network resources, and a workflow that will run on the Runner on each repository push or pull request for the example application. This will allow you to start to create multi architecture builds so that you can start leveraging Arm based AWS Graviton2 instances and the improved price/performance as well as power characteristics. [hands on]



In the post, Backwards Compatibility Testing for OpenSearch Vacha Shah and Sarat Vemulapalli show you how backwards compatibility testing works within OpenSearch, something that is used to test and determine the safe upgrade paths from a supported version to the current version.

Quick updates

Amazon Time Sync Service

Amazon Time Sync Service now allows you to easily generate and compare timestamps from Amazon EC2 instances with ClockBound, an open source daemon and library. This information is valuable to determine order and consistency for events and transactions across EC2 instances, independent from the instances’ respective geographic locations. ClockBound calculates your Amazon EC2 instance’s clock error bound to measure its clock accuracy and allows you to check if a given timestamp is in the past or future with respect to your instance’s current clock. On every call, ClockBound simultaneously returns two pieces of information: the current time and the associated absolute error range. This means that the actual time of a ClockBound timestamp is within a set range.

To get started, first make sure you are using Chrony. Then install the ClockBound daemon and library, or build your own library to integrate ClockBound into your application. For the best clock accuracy, we also recommend using the Amazon Time Sync Service. The Amazon Time Sync Service and Chrony are configured by default on Amazon Linux 2 instances.

Check out the code repo at the top of this post.
