ACTION: Important news for Builders who use Kubernetes

If you are using Kubernetes, then please make sure you check out this information post, k8s-registry-deprecation about the imminent freezing of the image registry. The Kubernetes project runs a community-owned image registry called to host its container images. On the 3rd of April 2023, the old registry will be frozen and no further images for Kubernetes and related subprojects will be pushed to the old registry. This registry replaced the old one and has been generally available for several months. Read more in the post, Image Registry Will Be Frozen From the 3rd of April 2023

Latest open source projects

The great thing about open source projects is that you can review the source code. If you like the look of these projects, make sure you that take a look at the code, and if it is useful to you, get in touch with the maintainer to provide feedback, suggestions or even submit a contribution.



staticwebsite-cli this Rust CLI tool makes it easy to deploy a static website to AWS. It builds and hosts the website, sets up a CDN and DNS, and provisions an SSL certificate. In order to manage DNS, the tool needs to be able to configure endpoints in your DNS zone. You must have an existing Route53 zone corresponding to the --domain-zone specified.


iam-ape or AWS Policy Evaluator (APE) is a new project from Orca that takes all of your AWS IAM policies attached to a User, Group, or Role object, and presents you with a single policy, summarising all of their actual permissions. To get a better idea of how this tool works, Tohar Braun has put together a blog post, Meet IAM APE: An Open Source Tool to Simplify AWS IAM Policy Management that provides more details on what you can do with it.

duckdb-athena-extension is a new project (very much alpha stage) from all round good egg Damon Cortesi (the first of two contributions this week) that provides an experimental extension for DuckDB, allowing you to import data by scanning an Athena table. Check the docs for the constraints and how to use this project.


amazon-emr-cli this is Damon's second project, and this tool helps you package and deploy your Amazon EMR Spark jobs. This is still very fresh, and under active development. Give it a go and provide your feedback to Damon and let him know what you think.


terraform-aws-email-files-dropped-in-s3 a new project from Cristian Măgherușan-Stanciu, who is on a crusade to create a new open source project every week. This weeks project sends an email when a file is dropped into an S3 bucket, including the file as an attachment. As Cristian said in a post about the project:

"The idea came from the AWS Reddit, where someone asked about this.

Then I realized I'd also love to have something like this so I started building it.

My use case is to save time reading the daily CSV reports from the AWS Marketplace, "conveniently" - for sure only for the AWS Marketplace team 😀 - dropped in an S3 bucket, one of the many usability papercuts of the AWS Marketplace seller user experience.


cloud-queue-for-quantum-devices is an open source, cloud-based application which allows quantum researchers to easily and securely submit and manage workloads destined for quantum devices, from anywhere in the world. This too will help you collaborate with researchers around the world. You can read more about this by checking out the supporting blog post, New open source tool expands access to lab-based quantum prototypes: Cloud Queue for Quantum Devices.

mpartman is a PostgreSQL partition management package. You can use Mpartman to manage partitions and subpartitions in PostgreSQL versions 11 – 15. With Mpartman, you can create RANGE and LIST partitions, merge, split, detach, and drop partitions. In addition to this, Mpartman supports partition retention fucntion and includes the set of partition information functions and views. The documentation covers typical use cases, installation, usage, and how it works under the cover.


aws-do-pcluster the Do Framework is a DevOps framework focused on simplicity, intuitiveness, and productivity. It helps you get more done. This project aims to make it easy to use AWS Parallel Cluster, by leveraging these principals. This project builds a container which contains all prerequisites, tools that are useful when working with Parallel Cluster, and the latest version of the pcluster cli. It comes with useful scripts to configure, create, and delete parallel cluster infrastructure.

template-for-closed-network-system-workloads-on-aws if you are operating in highly restrictive environments, then this repo will be of interest. It provides an example architecture that you can provision via CDK, that deploys a closed network infrastructure. The README provide an example use case:

In local government systems that require a high level security and network restrictions, we need to configure our architecture with characteristics from on-premise, like "Closed area networks" and "Allow NW access routes from AWS to on-premise network".

architecture of closed networks for workloads


amazon-msk-topic-resource is a custom CloudFormation resource that can be used to create and manage Kafka topics in MSK clusters. With this repo, you can deploy and manage Kafka topics in the same way you manage other application infrastructure.

how it works


aws-private-ca-matter-infrastructure this repo demonstrates the use of AWS CDK to set up Public Key Infrastructure (PKI) infrastructure using AWS Private CA to help you meet the requirements of the Matter PKI Certificate Policy (CP) approved on October 26, 2022. Matter is a new standard for smart home security and device interoperability. Matter uses X.509 digital certificates to identify devices. Matter certificates can be issued only by CAs that comply with the Matter PKI Certificate Policy (CP).


rosa-install-codepipeline This repository provides AWS CloudFormation templates, a Dockerfile, Bash scripts to deploy a PrivateLink Red Hat OpenShift on AWS (ROSA) cluster using a AWS CodePipeline. Includes security best practices such as use of Secrets Manager, KMS, immutable ECR repository, closed security groups with temporary internet access during installation and routing egress traffic through a separate Egress VPC connected through a Transit Gateway, storage of all installation parameters and logs in CodeBuild etc. This setup creates 3 private VPCs and subnets for deploying a PrivateLink ROSA cluster following AWS best practices. This is an end-to-end setup resulting in a functional ROSA cluster where a Kubernetes application can be readily deployed


aws-codecommit-s3-backups-with-terraform is a Terraform pattern to help you backup your AWS CodeCommit repositories to Amazon S3.

AWS and Community blog posts

Open Source Data Lakes

In the post, An Introduction to Modern Data Lake Storage Layers colleague Damon Cortesi dives hands on into Apache Hudi, Apache Iceberg, and Delta Lake taking a look at each of these engines and providing insights into how they function under the hood and his thoughts of the differences in each. If you find yourself wanting to know more about these different projects that on the surface do similar things, then I recommend you dive right in. [hands on]

Apache TinkerPop

Apache TinkerPop™ is an open source graph computing framework for both graph databases (OLTP) and graph analytic systems (OLAP). Stephen Mallette takes a look at some of the new features you can find in his post, Exploring new features of Apache TinkerPop 3.6.x in Amazon Neptune. There are plenty of new features to get excited about, so whether you are just starting out in graph databases and analytics, or a seasoned pro, dive in and catch up on the new capabilities. [hands on


If you are a regular reader of this newsletter, you may know that I love posts that cover collecting and analysing performance metrics. I really enjoyed reading this post, Monitor Amazon RDS for PostgreSQL and Amazon Aurora PostgreSQL performance using PGSnapper where Arabinda Pani and Abhinav Sarin look at how you can set up and use PGSnapper to periodically collect PostgreSQL database metrics and run customised queries to identify performance bottlenecks. [hands on]

We had more great posts on PostgreSQL last week, and Josh Hart and Maximilian Schellhorn put together this post, Choose the right PostgreSQL data access pattern for your SaaS application where they explore the different access patterns for PostgreSQL in a multi-tenant environment. It explores how factors such as AWS IAM Auth, compute isolation model and the database isolation model influence your implementation strategy. Well worth a read. [hands on]

Apache Iceberg

Apache Iceberg is an open table format for very large analytic datasets, which captures metadata information on the state of datasets as they evolve and change over time. In the post, Use Apache Iceberg in a data lake to support incremental data processing Flora Wu and Daniel Li look at how the Apache Iceberg framework helps resolve some of the challenges of modern data lakes, and walk you though a solution to process incremental data as well as how to tweak performance. [hands on]

Grafana is an open source analytics and interactive visualisation web application. You can use it to visualise any kind of data, and in this post, Visualize database privileges on Amazon Redshift using Grafana Yota Hamaoka shows how you can use some predefined Grafana dashboards to visualisation database privileges of Amazon Redshift. Database administrators can use these dashboards to quickly navigate through identities, objects, and privileges without writing SQL. [hands on]

Amazon MQ is a managed message broker service for Apache ActiveMQ and RabbitMQ that makes it easier to set up and operate message brokers on AWS. Amazon MQ now provides support for RabbitMQ version 3.10.17, which includes several important fixes and performance optimisations to the previously supported version, RabbitMQ 3.10.10.


Amazon Relational Database Service (Amazon RDS) for MariaDB now supports Amazon RDS Optimized Writes enabling up to 2x higher write throughput at no additional cost. This is especially useful for RDS for MariaDB customers with write-intensive database workloads, commonly found in applications such as digital payments, financial trading, and online gaming.

In RDS for MariaDB, you are protected from data loss due to unexpected events, such as a power failure, using a built-in feature called the “doublewrite buffer”. But this method of writing takes up to twice as long, consumes twice as much I/O bandwidth, and reduces the throughput and performance of your database. Starting today, Amazon RDS Optimized Writes provides you with up to 2x improvement in write transaction throughput on RDS for MariaDB by writing only once while protecting you from data loss and at no additional cost. Optimized Writes uses Torn Write Prevention, a feature of the AWS Nitro System, to reliably and durably write to table storage in one step.

Amazon RDS Optimized Writes is available as a default option from RDS for MariaDB version 10.6.10 and higher on db.r6i, db.r6g, db.r5b, db.x2iedn and db.x2idn database instances.


Amazon Aurora MySQL-Compatible Edition now supports authentication of database users using Microsoft Active Directory. You can use Active Directory to authenticate with Amazon Aurora using AWS Directory Service for Microsoft Active Directory or with your on-premise Active Directory by establishing a trusted domain relationship.

With support for Active Directory authentication in Amazon Aurora MySQL-Compatible Edition, you have access to single sign-on and centralised authentication of database users. Single sign-on reduces the operational overhead of database user management across multiple authentication approaches and credentials. Moreover, a centralised authentication approach enables customers to leverage native Active Directory credential management capabilities to manage password complexities and rotation. This allows you to effectively keep pace with the myriad of compliance and security requirements across the globe and improve the security posture of your critical business assets.

Active Directory authentication is supported for Aurora MySQL version 3.03 (compatible with MySQL 8.0.26) and higher.


Amazon Relational Database Service (Amazon RDS) for PostgreSQL now supports the latest minor versions PostgreSQL 14.7, 13.10, 12.14, and 11.19.

Apache Kafka

Amazon Managed Streaming for Apache Kafka (Amazon MSK) now supports Apache Kafka version 3.3.2 for new and existing clusters. Apache Kafka 3.3.2 includes several bug fixes and new features that improve performance. Some of the key features include enhancements to fetch from the closest replica and metrics. Amazon MSK will continue to use and manage Zookeeper for quorum management in this release.

For a complete list of improvements and bug fixes, see the Apache Kafka release notes for 3.3.2.
