AWS open source news and updates, #100

Feb 14th, 2022 - Instalment #100

Newsletter #100.

Happy Valentines everyone, and aside from reaching a landmark 100 episodes of this newsletter, this week we celebrate the love that many builders have for open source with more great new open source projects and content. Cuddle up to new projects that will help you build scalable systems, simplify your work with AWS DynamoDB, integrate your .NET applications with OpenSearch, keep on top of your VPC networks, and more. After checking those out, you can read the open source love letters featuring topics on Rust, Apache Airflow, Trivy, Envoy, KVM, Micronaut, Kotlin, Traefik Proxy, Apache Cassandra, MemQ and many more. If you prefer video content, then this week we have videos covering Apache Iceberg, Dokku, and Trivy. We feature a new WhitePaper on federated identity use cases and solutions for Apache Airflow, and wrap up with open source events, meetups and webinars happening over the next week or so.

Celebrating open source contributors

The articles posted in this series are only possible thanks to contributors and project maintainers and so I would like to shout out and thank those folks who really do power open source and enable us all to build on top of what they have created.

So thank you to the following open source heroes: Ambud Sharma, Shane Millar, Jeremy Persing, Justin Pirtle, Joan Morgan, Jim Thario, Mike Rizzo, Steve Coplan, Scott Morrison, Shovan Das, Mark Sailes, Sakis Kaliakoudas, Ivica Kolenkaš, Michael Matur, Shane Miller and Carl Lerche.

Make sure you find and follow these builders and keep up to date with their open source projects and contributions.

Latest open source projects



joiful-dynamo is an open source library from Chocolate Soup uses Typescript Decorators to easily let developers to manage data models. This IS NOT a complete ORM, but a facilitator to make the experience of using AWS DynamoDB easier and with less code repetition.


amazon-managed-service-for-prometheus-roadmap is the public space where you can add and influence feature requests for the Amazon Managed Service for Prometheus roadmap and allows all AWS customers to give direct feedback.


amazon-managed-grafana-roadmap is the public roadmap for Amazon Managed Grafana. We share information about what we are working on and equally, you can use this repo to provide feedback and suggest features. Note that this roadmap presents features that we are considering developing, however it does remain subject to change from time to time.



opensearch-net this project is the official high-level .NET client of OpenSearch.


aws-vpc-network-resource-counter this looks like an incredibly helpful and useful project, which I am going to deploy in my own AWS environment. This project is intended to help with tracking networking resources in a single Amazon VPC. It will create an AWS Lambda function that will count specific network resources and create CloudWatch metric for each measurement. The measurements are published at an interval of your choice. Check the README for more details.


automated-prefix-list-to-security-group-synchronization this repo provides a solution designed to automatically synchronise private IP addresses for ENIs associated with a Security Group to a Managed Prefix List in the same or different region as the Security Group. This can enable strict IP based filtering across region or when crossing a Transit Gateway, as well as when using a middle box appliance in a VPC where security group referencing is not supported. To help you get started with this, Scott Morrison and Shovan Das have put together a blog post, Automated VPC prefix list population for cross-Region and in-Region security group referencing


Demos and Samples


aws-virtual-waiting-room AWS Virtual Waiting Room solution helps absorb and control incoming user requests to your website during an unusually large burst of traffic, usually due to a large-scale event. Justin Pirtle, Joan Morgan, and Jim Thario have put together this blog post, Introducing AWS Virtual Waiting Room to help you get started and walk you through the key components of this project and how to get it up and running.



subtitle-generator-cdk-app this sample provisions the infrastructure, backend, and frontend required for a subtitle generator app with AWS CDK.



pizza-delivery-tracker This sample project contains a map-based pizza ordering app with real-time tracking of your delivery. The browser-based frontend shows a map with your current location and lists all pizza places nearby. You can select one to order a pizza from there. Shortly after ordering, a delivery route is calculated and you can monitor the delivery progress in real-time while the pizza icon is moving closer and closer to your location on the map.


AWS and Community blog posts


During re:Invent, one of the most popular sessions in the Open Source track was Using Rust to minimise environmental impact, presented by Shane Miller and Carl Lerche.

I am delighted they are both back, this time writing on this topic in their post Sustainability with Rust and diving a little deeper into this topic with plenty of nice data points. This weeks must read post.



Aqua Security’s open source project Trivy is a scanner for vulnerabilities and configuration issues in container images, file systems, and Git repositories. In the post, Identify Security Risks in AWS CloudFormation Templates with Trivy Steve Coplan looks at a new feature of this project that now lets you scan AWS CloudFormation templates to help developers better identify and remediate security issues within infrastructure as code (IaC) templates.


Simeon Adeniyi Oladokun has put together a great post showing you how you can deploy an AWS DataSync agent on Linux KVM hypervisor host, providing a cost-effective hypervisor solution that creates a simpler and easier migration of large datasets from on-premises storage systems to AWS storage services. See how by following along in, Simplify data migrations using an AWS DataSync agent on Linux KVM Hypervisor

In his post, Using a CI/CD Pipeline to Inject an Envoy Proxy Sidecar Container into an Amazon ECS Task Mike Rizzo demonstrates how you can use a pipeline to inject an Envoy proxy sidecar container into your ECS tasks so that they can be used with AWS App Mesh. Why would you want to do this I can hear you Mike puts in his post:

By using a pipeline to build the required task and service definition files, developers can focus on building service logic with minimal effort required on service configuration. The pipeline can also be used to enforce any deployment conventions and policies as may be required by a platform team.

MemQ is a new open source PubSub system from the folks at Pinterest. It uses a decoupled storage and serving architecture similar to Apache Pulsar and Facebook Logdevice, but relies on a pluggable replicated storage layer i.e. Object Store's such as Amazon S3, for storing data. Ambud Sharma, a tech lead at Pinterest, discusses MemQ in more details, and shares how it has been powering near-real-time data transportation use cases whilst being over 90% more cost-efficient in some cases. Read more in the post, MemQ by Pinterest: An efficient, scalable, cloud-native publish/subscribe system


Micronaut + Kotlin + Graal VM

Sakis Kaliakoudas has put together this post, Serverless on AWS Lambda With Micronaut + Kotlin + Graal VM that takes a look at the technology stack decisions for Caribou, a developer tool that helps developers use data-driven insights to manage their technical debt. There is a hint in the title I guess, but read on to find out more and why.

Apache Airflow

In his post, My Thoughts on AWS Managed Workflows for Apache Airflow Ivica Kolenkaš shares his thoughts and observations on Amazon Managed Workflows for Apache Airflow (MWAA) and whether you it can replace self-hosted Airflow in his use cases.

I also started the first in a series of blog posts that will share my experiences as I look to contribute to the upstream Apache Airflow project, in my post Contributing to the Apache Airflow project.


Michael Matur shows you how configure your Ingress Controller Traefik Proxy with the support of HTTP/3 on an EKS cluster in his post, How to use Traefik Proxy and HTTP/3 on AWS EKS [hands on]

Videos of the week

Apache Iceberg

Apache Iceberg is a high-performance format for huge analytic tables. Iceberg brings the reliability and simplicity of SQL tables to big data, while making it possible for engines like Spark, Trino, Flink, Presto, and Hive to safely work with the same tables, at the same time. Dremio walks you through how to set up the Iceberg Glue connector, write an Iceberg table using AWS Glue, and analyse it with Dremio.


Perfect timing given the post on Trivy above, last week I had a quick look at this video from Rawkode Academy that takes a look at continuously scanning for misconfiguration and vulnerabilities within your container images with Aqua's open source project, Trivy.


Dokku is an open source platform as a service, and similar in some ways to Heroku, and services like that. In this video, Jeremy Persing shows you how to get this up and running on AWS.
