海外TECH DEV Community AWS open source news and updates, #127 https://dev.to/094459/aws-open-source-news-and-updates-127-56n9 AWS open source news and updates September th Instalment WelcomeWelcome to the AWS open source newsletter edition 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 ODE 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 FeedbackIf you enjoy reading this newsletter please let me know how we can improve it as well as how AWS can better work with open source projects and technologies by completing this very short survey that will take you probably less than seconds to complete Thank you so much Celebrating open source contributorsThe 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 Gunner Grosch Thirumalai Aiyalu Justin Garrison Todd Neal Alex Kestner Kevin Hakanson Mike George Vikram Venkataraman Abhi Khanna Michael Hausenblas Imaya Kumar Jagannathan Rodrigue Koffi nkmehta and Toshal Dudhwala Josh Thornes Jack Mazanec and 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 projectsThe 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 Toolscfn tracecfn 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 cfntree view cfn HOT OFF THE PRESS if you were watching the latest episode of the Build on AWS open source SE 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 tuneraws 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 surfsurf 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 eksairflow 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

OpenSearch now ready for you to get your hands on James McIntyre put together this blog post OpenSearch is ready for download that takes a look at three key new features Segment replication remote backed storage and drag and drop visualisation AWS CDKCustomers 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 plantumlaws 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 that includes icons updates from Q 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 MySQLAmazon Relational Database Service Amazon RDS for MySQL now supports MySQL minor version 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 of container startup time but on average only 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 Videos of the weekKarpenterCheck out the Containers from the Couch crew and join Justin Garrison Todd Neal and Alex
