Welcome to issue #187 of the AWS open source newsletter, the newsletter where we try and provide you the best open source on AWS content.
As always, this week we start with a round up of some freshly baked new projects for you to practice your four freedoms. This week we have new projects that help you optimise working with EBS volumes on EC2, a tool to help you document your architectures, a large language model benchmarking tool, a tool to help you optimise your S3 storage files, a data validation framework, and a really nice Java workshop Also featured in this weeks edition is content on projects such as Blazor, PostgreSQL, MySQL, Finch, Kubernetes, TensorFlow, Apache Airflow, AWS CDK, AWS Copilot, OpenZFS, Powertools for Lambda, Ruby, Cedar, OpenSearch, projen, Amazon Corretto, and Event Ruler
I am particularly delighted this week in the videos, so please make sure you check those out. We have three really amazing sessions recorded that cover Cedar (my video of the week), writing Python extensions for OpenSearch, and how you can use projen to abstract your CI/CD pipelines. Great stuff.
Make sure you stick to the very end and check out the Events section at the end - and if you are running an open source event and want me to include it for broader visibility, please drop me a message at ricsue at amazon dot com.
Feedback
Please please please take 1 minute to complete this short survey.

The articles and projects shared in this newsletter are only possible thanks to the many contributors in open source. I would like to shout out and thank those folks who really do power open source and enable us all to learn and build on top of what they have created.
So thank you to the following open source heroes: Lasith Koswatta Gamage, David Boyne, Matt Muller, Emina Torlak, Franck Pachot, dB., Johannes Koch, Muhammad Saipul Rohman, Fiqri Ismail, Justin Alvarez, Phil Estes, Alan Halcyon, George John, Harish Kuna, Sanjeev Ganjihal, Scott Perry, Olawale Olaleye, Parnab Basak, Heitor Lessa, Noor Fairoza and Daniel Whitehead

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. The projects mentioned here do not represent any formal recommendation or endorsement, I am just sharing for greater awareness as I think they look useful and interesting!

ebs-bootstrap is a very handy tool from Lasith Koswatta Gamage that solves a very specific problem. Lasith reached out to explain more about the "itch" that needed to be scratched. ebs-bootstrap is a tool that provides a safe and as-code approach for managing block devices on AWS EC2. If you need precise and consistent control over your EBS volumes when attaching them to your EC2 Nitro based instances, you need to check out this project. The README provides some additional example configurations, and there is a blog post in the works which I will share once it has been published. Very nice work Lasith!

cloudcatalog colleague David Boyne has put together another project, that is a fork of one his earlier projects (EventCatalog) that provides a similar capability, but this time helping you to document your AWS architecture. Check out the README for more details, including an example architecture that was documented. Very cool stuff indeed.

s3-small-object-compaction This solution deploys a serverless application to combine ("compact") small objects stored in a given Amazon S3 prefix into a single larger file. Larger files enable cost effective use of S3 storage tiers that have a minimum billable object size (e.g. 128 KB). It can also improve performance when querying data directly with Amazon Athena. The sample code is written using the AWS Cloud Development Kit in Python.

foundation-model-benchmarking-tool is a Foundation model (FM) benchmarking tool. Run any model on Amazon SageMaker and benchmark for performance across instance type and serving stack options. A key challenge with FMs is the ability to benchmark their performance in terms of inference latency, throughput and cost so as to determine which model running with what combination of the hardware and serving stack provides the best price-performance combination for a given workload.

automated-data-validation-framework When you are undertaking data migration projects, a significant time is spent in doing the data validation and lot of manual efforts being spent. This repo provides a framework developed that helps to simplifying this problem by automating full data validation with some simple config files, and running the framework on EMR. It will create summary and detail data validation report in S3 and show up on Athena tables. You will need to do some initial work to setup this framework and create config files which has table names to compare. Very cool indeed.

java-on-aws is a fantastic resource for all Java developers who want to dive deeper on how to deploy their Java applications on AWS. Taking a sample application, the workshop looks at how you can containerise it, and then deploy it across a number of different compute environments - from serverless to Kubernetes. If you are a Java developer, do not miss this workshop!

ecs-gpu-scaling This repository is intended for engineers looking to horizontally scale GPU-based Machine Learning (ML) workloads on Amazon ECS. By default, GPU utilisation metrics are not part of the predefined metrics available with Application Autoscaling. As such, you implement auto scaling based on custom metrics. For NVIDIA-based GPUs, you use DCGM-Exporter in your container to expose GPU metrics. You can then use metrics such as DCGMFIDEVGPUUTIL and DCGMFIDEVGPUTEMP to determine your auto scaling behaviour. The README provides links to all the additional resources you need to get this up and running.

Each week I spent a lot of time reading posts from across the AWS community on open source topics. In this section I share what personally caught my eye and interest, and I hope that many of you will also find them interesting.

I am currently writing this in Brussels, as Fosdem is upon us. Today is PGDay so what better way to kick things off this week than with AWS Hero Franck Pachot as he dives deep into the topic of generating unique identifiers in your application in his post, UUID in PostgreSQL. From PostgreSQL to MySQL, another popular open source database, and in Unveiling the Power of Zero-ETL Integration between Amazon RDS for MySQL and Amazon Redshift Muhammad Saipul Rohman looks at one of the announcement from last year that helps yo simplify how you can run your extract, transform, and load operations when looking to move your data to a data warehouse. Finally for this short roundup we have AWS Community Builder Fiqri Ismail, who has put together a great post if you are interested in or currently using Blazor, an open source web frontend framework built on top of dotNET. In The quickest way of deploying a Blazor Web Assembly app to AWS Amplify, Fiqri provides a step by step guide on how to create a Blazor Web Assembly project and deploy this to AWS Amplify as a frontend.

Finch is a command line client for building, running, and publishing Linux containers that I have featured in previous editions of this newsletter (and on a personal note, I have transitioned to for all my container developer needs as of 2024). Hot off the press last week was Justin Alvarez and Phil Estes with news that you can now use Finch on Windows, in the post Finch Container Development Tool: Now for Windows

We had a great selection of Kubernetes related posts last week. Alan Halcyon, George John, and Harish Kuna provided some great insights in how Amazon EKS tests for scalability in the post, How Amazon EKS approaches Scalability

Sanjeev Ganjihal and Scott Perry are up next, showing you how you can use AWS Trainium with Neuronx-nemo-megatron on Amazon EKS to tackle the rising computational demands and cost challenges in training advanced AI models. If that sounds like something you need to know more about, then dive into Train Llama2 with AWS Trainium on Amazon EKS

My good friend Parnab Basak has created some great content for Apache Airflow users, and he is back again with an update to Deploying to Amazon Managed Workflows for Apache Airflow with CI/CD tools. This is a very detailed and comprehensive guide, and will show you how you can extend existing CI/CD processes and tools to deploy code to Amazon MWAA. Nice! [hands on]

There were a couple of great updates last week for fans and users of Powertools for Lambda.
First up is Heitor Lessa who shared this tweet (with screen shot) on how Powertools for AWS partnered with the AWS Crypto team to make data confidentiality and integrity more accessible. That is a massive win, so great news.
The second update from Heitor was news that Powertools for Lambda now has a dedicated website. Head on over to powertools.aws.dev for all your Powertools on Lambda needs!

Amazon FSx for OpenZFS, a service that provides fully managed file storage powered by the popular OpenZFS file system, now provides 14% higher levels of I/O operations per second (IOPS) at no additional cost, bringing the new maximum IOPS level to 400,000. The increased IOPS levels enable you to improve price–performance for IOPS-intensive workloads like Oracle databases and optimise costs for workloads like periodic reporting jobs with IOPS requirements that vary over time. Check the announcement page for details around AWS region availability for this update.
In other OpenZFS news, Noor Fairoza and Daniel Whitehead have also written Boosting Unreal Engine Performance with Amazon FSx for OpenZFS as a Shared Derived Data Cache that provides a step-by-step guide to configure Amazon FSx for OpenZFS as a Derived Data Cache (DDC) for Unreal Engine [hands on]

Trusted Language Extensions for PostgreSQL (pgtle) is an open source development kit to help you build extensions written in a trusted language, such as PL/Rust, that run safely on PostgreSQL. pgtle now supports new crates for PL/Rust such as croaring-rs and num-bigint, enabling you to build more of your extensions on RDS for PostgreSQL. PL/Rust, a PostgreSQL trusted procedural language, combines the performance and resource efficiency of compiled languages like C and provides memory safety so that an unprivileged user can run code in the database.
Rust crates extend functionality in PL/Rust to help support more use cases such as for analytics, search, and security applications. croaring-rs adds support for roaring bitmap, a data type that provides better compression and lower memory utilisation compared to conventional bitmaps. Roaring bitamps are used for applications that require high performance lookups with a high compression ratio, such as analytics and big data. The num-bigint crate adds precision handling for arbitrarily large sized integers, which is used for security and scientific applications.
Support for num-bigint and croaring-rs crates is available on database instances in Amazon RDS running PostgreSQL 16.1-R2 and higher, 15.5-R2 and higher, 14.10-R2 and higher, and 13.13-R2 and higher in all applicable AWS Regions.
Also announced last week was news that Amazon Aurora PostgreSQL-Compatible Edition now supports PostgreSQL major version 16 (16.1). PostgreSQL 16 adds support for SQL/JSON constructors and identity functions, more query types that can use parallelism, and the ‘pgstatio’ view that provides statistics on I/O usage.

AWS SDK for Ruby V3 now supports RBS type signatures. RBS is a language to describe the structure of Ruby programs. Read more about this in the post from Matt Muller, Announcing RBS support for AWS SDK for Ruby V3

Event Ruler is an open source project that provides a Java library that can match rules against events in near real-time against any traffic. Today, EventBridge matches more than 2.6 trillion events per month for over 1.5 million customers. By running on Open Source Ruler, EventBridge can now collaborate directly with the broader developer community and will actively contribute to building new and enhanced filtering capabilities that anyone can use through the Apache 2.0 License.
Amazon EventBridge event matching now runs on Open Source Event Ruler v1.50, enabling advanced filtering capabilities such as combining anything-but filtering (matching anything except for the value) with suffix filtering (matching against characters at the end of a value), and equals-ignore-case filtering (matching against a string regardless of case). For example, you can now match against values that don’t end with a specific file type such as .png or .jpeg. You can also combine prefix filtering (matching against characters at the beginning of a value) and suffix filtering with equals-ignore-case filtering.
Amazon EventBridge Event Bus is a serverless event router that enables you to create scalable event-driven applications by routing events between your own applications, third-party SaaS applications, and AWS services. You can set up rules to determine where to send your data, allowing applications to react to changes in your data as they occur.

This is a fabulous talk from Emina Torlak that dives deep into Cedar and how it implements provable security. This is this weeks must watch video.

The Extensions SDK, a new experimental feature in OpenSearch 2.9, allows you to extend OpenSearch and independently scale workloads without impacting cluster availability. But did you know that this feature now allows you to write one of these Extensions in Python? No need to use Java, and there’s no JVM required, making it super easy to do. In this video, dB. will show you how to write a plugin, how to write an extension in Java, and then how to write an extension on Python. dB. also demystifys some of the lowest levels of OpenSearch internals, such as its binary transport protocol.

Great video from AWS Hero Johannes Koch who takes a look at projen, an open source project that lets you define an abstract CI/CD pipeline which can then be rendered / generate for different CI/CD tools.
