September 16th, 2022 - Instalment #127

Welcome

Welcome to the AWS open source newsletter, edition #127. I hope some of you were able to catch Derek and myself sharing a peek at this edition, and enjoyed as our special guest, AWS Hero Ian Mckay walked us through some of his open source projects. It was very cool indeed, and if you have not yet watched, Ian shares an early glimpse of a new project - so make sure you check that out..

As always, this week we feature more great new open source projects from AWS and around the AWS community. "cfn-trace" is a cli tool that provides x-ray like traces for your Cloudformation stacks, "tree-view-cfn" extends the recently launched tree view for CDK resources to Cloudformation stacks, "aws-lambda-live-tuner" takes AWS Lambda Power tuning and makes it real time, "surf" allows you to easily search your Cloud resources via the cli, "airflow-on-eks" provides a reference stack for self managed Apache Airflow, "SEGG" a tool for those working with Step Functions, "centralised-egress-proxy" a nice example of how to deploy Squid proxy servers, and many other projects.

We also have blog posts and technical articles covering open source technologies including Kubeflow, OpenSearch, Jenkins, Amazon EMR, Apache Spark, AWS CDK, AWS ParallelCluster, GitOps, AWS Distro for OpenTelemetry, Prometheus, Grafana, Firecracker, Rust, O3DE, Kotlin, and more! Make sure you don't miss the videos section, this week featuring Karpenter and getting started with Amazon EKS. We finish as always with a round up of events.

Celebrating open source contributors

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: Samrose Ahmed, Gunnar Grosch, Thirumalai Aiyalu, Justin Garrison, Todd Neal, Alex Kestner, Kevin Hakanson, Mike George, Vikram Venkataraman, Abhi Khanna, Michael Hausenblas, Imaya Kumar Jagannathan, Rodrigue Koffi, Toshal Dudhwala, Josh Thornes, Jack Mazanec, Othmane Hamzaoui, Vara Bonthu, Melody Yang, Karthik Prabhakar, Paul Roberts, Mohamed (Mo) Ahmed, Viktor Farcic, Madeleine Song, Elena van Engelen - Maslova, Valentina Palmiotti, Jan Ritter, Isan-Rivkin, and Victor Iwuoha

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.

Tools

cfn-trace

cfn-trace this tool from Grunet looks very interesting for AWS Cloudformation users. It captures Cloudformation nested stack deploy events as traces. The tool takes the stack events from when they were updated and converts that info into distributed tracing-style waterfall diagrams to visualise the deployments. Work in progress, so keep an eye on this tool.

tree-view-cfn

tree-view-cfn HOT OFF THE PRESS if you were watching the latest episode of the Build on AWS open source (S01E02) AWS Hero Ian Mckay walked us through some of his open source projects, and mentioned this new project, tree-view-cfn. So what does it do? Well if you look at the Quick Updates section below, you will see that a new Tree View was introduced as a way to better visualise the resources that your CDK applications deploy. TreeViewCFN is an open source project that can convert any CloudFormation template into one that allows the console to use the tree-view. Very cool indeed!

aws-lambda-live-tuner

aws-lambda-live-tuner this looks like a super interesting tool from Jan Ritter for those developers writing AWS Lambda functions. AWS Lambda Live Tuner tests memory configurations based on real incoming events instead of a single test event. Influenced by my colleagues Alex Casalboni's tool, AWS Lambda Power Tuner, this is what Jan has to say:

Let's imagine we are testing a Lambda function that processes a queue, since the Lambda function is idempotent, messages that have already been processed will be successfully processed again. Using the same test event on all invocations might falsify the results because all subsequent invocations after the initial one might be way faster (event was already processed before). Using different incoming events instead helps you test the actual behaviour of the Lambda.

surf

surf this is a nice tool from Isan-Rivkin that provides a CLI Text Search across your infrastructure platforms, think of it like grep for infrastructure.

airflow-on-eks

airflow-on-eks this Terraform module helps you deploys the production ready Self-managed Apache Airflow deployment on EKS. Using this it will help you deploy all the AWS resources you need. Check the docs for a detailed breakdown.

shepard

shepard Shepard is a one-stop shop to turn a container into a highly scalable easy to manage workflow in AWS. It is a machine that makes machines that execute your code - very meta!

SEGG

SEGG Step Function Express Graph Generator (or SEGG) gives visibility to express each execution of a AWS Step Function Express Workflows making it much easier to build and troubleshoot. This tool will help you see the execution visually similar to the execution graph of a Step Function Standard Worflow provided by AWS, and build applications at a much faster rate. Very cool. Check out the short video that provides more info.

iam-identitycenter-identitystoreapi-operations

iam-identitycenter-identitystoreapi-operations this project provides examples and sample code to manage and audit AWS IAM identity store User and Group operations at scale using APIs.

Demos, Samples, Solutions and Workshops

AWS_File_Trans_Lamda_S3_SN

AWS_File_Trans_Lamda_S3_SN Victor Iwuoha has put together this sample project to show you how you can easily build a serverless data engineering pipeline using a collection of AWS services.

aws-sec-checkov-terraform

aws-sec-checkov-terraform Checkov is a tool that perform security analysis on terraform code. This demo is used in a pipeline that runs automatically every time there is a code commit in the git repository (AWS CodeCommit). The pipeline uses Checkov to analyse terraform code and requests a validation of the security team to continue with environment creation/change

aiops-serverless

aiops-serverless Under the Sea is an official AWS workshop delivered by AWS SAs and AWS Partners to help customers and partners to learn about AIOps with serverless architectures on AWS. Under the Sea is an exciting MMORPG developed by the famous entrepreneur behind Wild Rydes, the most popular unicorn taxi service in the world. This time the game design team went above and beyond to bring us a steam-punk adventure 20,000 leagues under the sea. The engineering team brought to live this technology masterpiece that can host hundreds of players simultaneously.

centralised-egress-proxy

centralised-egress-proxy this repo contains a re-usable and customisable solution based on a fleet of open source Squid proxies running on Amazon Elastic Container Service (ECS) with AWS Fargate. Internet access is provided centrally via a NAT Gateway and an Internet Gateway deployed in the central VPC. Amazon ECS uses a Network Load Balancer (NLB) configured as an endpoint service to make the solution available to ‘spoke’ VPCs. Interface endpoints are deployed into the ‘spoke’ (application) VPCs to enable resources inside these VPCs to use the deployed endpoint as its proxy server.

building-resilient-apps-amazon-dynamodb-global-tables

building-resilient-apps-amazon-dynamodb-global-tables this repository has sample code demonstrating how to build a resilient multi-region application with DynamoDB Global Tables as the data store.

AWS and Community blog posts

Matano is an open-source security lake platform for AWS. In this post, Serverless asynchronous Iceberg data ingestion, Samrose Ahmed looks at how they leverage Apache Iceberg as part of their main data lake store, showing how they ingest data.

OpenSearch

The k-NN problem is relatively simple compared to other ML techniques: given a set of points and a query, find the k nearest points in the set to the query. As the number of data points reaches the hundreds of millions or even billions, scaling a k-NN search system can be a major challenge. In Choose the k-NN algorithm for your billion-scale use case with OpenSearch Jack Mazanec and Othmane Hamzaoui cover different algorithms and techniques used to perform approximate k-NN search at scale (over 1 billion data points) within OpenSearch. [hands on]

Quick updates

OpenSearch

The latest version of OpenSearch hit the download links this week, with OpenSearch 2.3 now ready for you to get your hands on. James McIntyre put together this blog post, OpenSearch 2.3 is ready for download! that takes a look at three key new features: Segment replication, remote-backed storage, and drag-and-drop visualisation.

AWS CDK

Customers using CDK want a simple way to map the resources synthesised in a CloudFormation template back to the source CDK Construct. In an effort to display all resources in a CloudFormation template the Management Console loses the hierarchical nature of CDK Constructs, which customers are used to today. CDK Construct tree view in the CloudFormation console is intended for the customers who want to observe the context from which the resources were created to the CloudFormation console, in order to provide a better, focused experience.

Tree view capability will automatically organise the resources that were synthesised by AWS CDK Constructs: the top level will be the AWS CDK Construct (by name) and all resources will be placed as a second level under the Construct that generated them. As a user, the Constructs tree view will allow you to easily identify the hierarchy of the resources and their logical location in the application: each resource is placed in an app-logical context, which is presented as a tree view in CloudFormation Console.

aws-icons-for-plantuml

aws-icons-for-plantuml provides a way to use the official AWS Architecture Icons with diagrams-as-code tool PlantUML. Kevin Hakanson reached out to me to tell me more about the latest release, 14.0, that includes icons updates from Q3 2022. Additionally, community member Matthew Warman contributed a PR which added support for Groups, enabling more types of architecture diagrams. In a related blog titled Sequence Diagrams enrich your understanding of distributed architectures, Kevin shows how to use PlantUML and the AWS Icons for PlantUML to explore the design of a serverless architecture.

MySQL

Amazon Relational Database Service (Amazon RDS) for MySQL now supports MySQL minor version 8.0.30. We recommend that you upgrade to the latest minor versions to fix known security vulnerabilities in prior versions of MySQL, and, to benefit from the numerous fixes, performance improvements, and new functionality added by the MySQL community.

Seekable OCI (SOCI)

Seekable OCI (SOCI) is a technology open sourced by AWS that enables containers to launch faster by lazily loading the container image. SOCI works by creating an index (SOCI Index) of the files within an existing container image. This index is a key enabler to launching containers faster, providing the capability to extract an individual file from a container image before downloading the entire archive.

Most methods for launching containers download the entire container image from a remote container registry before starting the container. Waiting for all of the data is wasteful in cases when only a small amount of data is needed for startup. Prior research has shown that the container image downloads account for 76% of container startup time, but on average only 6.4% of the data is needed for the container to start doing useful work.

There are various solutions to this problem, including reducing the size of a container image and pre-fetching container images to local storage. Lazy loading is an approach where data is downloaded from the registry in parallel with the application startup. Container images are stored as an ordered list of layers, and layers are most often stored as gzipped tar files. It’s usually not possible to fetch individual files from gzipped tar files. Some projects enable lazy loading through format conversion. One such project is stargz-snapshotter, which takes an existing OCI image and builds a new OCI image with an embedded table of contents. With SOCI, we borrowed some of the design principles from stargz-snapshotter, but took a different approach. A SOCI index is generated separately from the container image, and is stored in the registry as an OCI Artifact and linked back to the container image by OCI Reference Types. This means that the container images do not need to be converted, image digests do not change, and image signatures remain valid.

An open-source build tool is used to create SOCI indices for existing OCI container images and a remote snapshotter, called soci-snapshotter, provides containerd the ability to lazy load images that have been indexed by SOCI. SOCI and the soci-snapshotter are open sourced under Apache 2.0.
