AWS open source news and updates, #119

July 1st, 2022 - Instalment #119

Welcome to regular and new readers alike, to the AWS open source newsletter episode #119.

This week we feature more new open source projects, such as "cdk-bill-bot", a tool that can help you reduce AWS bill surprises, "steampipe-mod-aws-perimeter" helps you look for resources that are publicly accessible, "aws-cloudformation-diagrams" is a nice visualisation tool for CloudFormation users, "aws-swagger-ui" a project to help you set up Swagger UI for API Gateway, "kinesis-hot-shard-advisor" a handy tool that helps you identify whether you have hot key or hot shard issues on your Kinesis data streams, and many more.

We also have blog posts, tutorials and videos on topics that include RStudio, Amazon Corretto, Terraform, Linux, Hugging Face, Syne Tune, Apache Airflow, OpenSearch, Apache Iceberg, Pulumi, Lustre, Apache Spark, PostgreSQL and many more. Finally, make sure you check out the events section for the latest open source events, there are some great events coming up over the next week.


At Amazon we work backwards from our customers, and one of the ways we do that is collecting data to help us know what is important and what we should focus on. Please could you complete this simple, anonymous survey. The first 25 will get an AWS $25 credit code.

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: David Tippett, Steven Hilion, Adam Bien, Lerna Ekmekcioglu, Jack Iu, Arun Km, Rohit Bhosale, Abhishek Ray, Jeremy Cowan, Akshit Khanna, Arun Thangaraj, Chaitanya Varma Mudundi, Sekar Srinivasan and Christian Bonzelet

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.



cdk-bill-bot this project from Christian Bonzelet enables AWS customers to proactively monitor their infrastructure costs and identify unforeseen expenses in a timely manner. Bill wants to prevent AWS customers from receiving bad surprises in their monthly bill. Therefore he addresses two primary problem areas, first, cost history is not monitored on a regular basis, and second, basic cost optimisation best practices are not setup.

As Christian points out in his README, this is an alpha stage project so use at your own risk and beware of potentially breaking changes.


steampipe-mod-aws-perimeter the latest open source project from the fine folk at Turbot, this project provides an AWS perimeter checking tool that can be used to look for resources that are publicly accessible, shared with untrusted accounts, have insecure network configurations, and more.

aws-cloudformation-diagrams another visualisation project, this time allowing you to generate dynamic diagram of AWS Cloudformation template from YAML file. Using Python, you will be able to quickly create some pdf architecture from your CloudFormation templates in no time at all.


aws-icons-for-plantuml PlantUML is an open-source tool allowing users to create diagrams from a plain text language. This repository contains images, sprites, macros, and other includes for Amazon Web Services (AWS) services and resources. You can use this repository to create PlantUML diagrams with AWS components. All elements are generated from the official AWS Architecture Icons and when combined with PlantUML and the C4 model, are a great way to communicate your design, deployment, and topology as code.

simpleiot-cli last week I shared the SimpleIOT SDK. This week we have the command-line-interface (CLI) for the SimpleIOT framework. SimpleIOT abstracts out IoT device connectivity and hides the underlying details so you can focus on your application's unique features.

Demos, Samples, Solutions and Workshops


eventbridge-events-to-vpc shows you how to send EventBridge events to a private endpoint in a VPC using a Lambda function to relay events. This solution deploys the Lambda function connected to the VPC and uses IAM permissions to enable EventBridge to invoke the Lambda function. In this solution, you set up an example application with an EventBridge event bus, a Lambda function to relay events, a Flask application running in an EKS cluster to receive events behind an Application Load Balancer (ALB), and a secret stored in Secrets Manager for authenticating requests. This application uses EKS and Secrets Manager to demonstrate sending and authenticating requests to a containerized workload, but the same pattern applies for other container orchestration services like ECS and your preferred secret management solution.

step-functions-workflows-collection this repo contains Step Functions workflows that shows how to orchestrate multiple services into business-critical workflows with minimal code. You can use these workflows to help develop your own projects quickly.


aws-test-automation-for-devops-using-aws-cdk this sample code shares methods and patterns for applying test automation in CI/CD of AWS in order to transform DevOps through test automation. With this sample, you can implement test automation directly through practice.

aws-sso-configuration-automation this project accelerate AWS Single Sign-On (SSO) implementation using AWS CDK. This CDK program allows you to conveniently define your own permission sets and assignments without the need to tediously create your own AWS CloudFormation templates for your AWS SSO deployment minimising the risk of human misconfigurations.

AWS and Community blog posts

Spring Boot

Gary Stafford has put together his latest blog post, Developing Spring Boot Applications for Querying Data Lakes on AWS. In this post Gary explores how to build an example Java Spring Boot RESTful Web Service that allows end-users to query data stored in a data lake on AWS. The RESTful Web Service will access data stored as Apache Parquet in Amazon S3 through an AWS Glue Data Catalog using Amazon Athena. The service will use Spring Boot and the AWS SDK for Java to expose a secure, RESTful Application Programming Interface (API). As always, must read post this week. [hands on]

Amazon Corretto

Check out Using Amazon Corretto (OpenJDK) for lean, fast, and efficient AWS Lambda Applications where Adam Bien discusses how you can launch large, monolithic applications on top of AWS Lambda, showing that they perform well and are cost effective. He also introduces running Amazon Corretto on ARM64 using Lambda’s Graviton2-based offering. Finally Adam demonstrates how you can use Amazon Corretto with Quarkus to build micro services quickly and at low cost. Must read for Java developers this week. [hands on]


Pulumi is an open-source Infrastructure as Code (IaC)tool, similar to Terraform, with a key difference between Pulumi and Terraform is that Pulumi lets you choose a number of different general-purpose programming languages whereas Terraform has a domain-specific language called Hashicorp Configuration Language (HCL). Abhishek Ray has put together this blog post, How to use Pulumi and Python to create an EC2 instance to show you the basics and help you get started [hands on]

Apache Iceberg

Apache Iceberg is an open table format, originally designed at Netflix in order to overcome the challenges faced when using existing data lake formats. It is getting a lot of interest, and this week we have a couple of blog posts that will help you get to know this open source technology in more detail.

First up we have Chaitanya Varma Mudundi from RedHat, who provides a nice overview of Apache Iceberg and some ideas of how you can run this on AWS in his post, Apache Iceberg: An Introduction from Rackspace on Running the New Open Table Format on AWS

Following that we have the post, Build a high-performance, ACID compliant, evolving data lake using Apache Iceberg on Amazon EMR from Sekar Srinivasan. In this post, Sekar discuss' the modern data lake requirements and the challenges—including support for ACID transactions and concurrent writers, partition and schema evolution—that come with these, before showing how Apache Iceberg solves these challenges. There is a sample notebook that you can use to follow along, to see how you can run Apache Iceberg on Amazon EMR using the AWS Glue Data Catalog as the metastore, and query the data using Athena. [hands on]


Very nice post, Multi-Region Terraform Deployments with AWS CodePipeline using Terraform Built CI/CD from Lerna Ekmekcioglu and Jack Iu where they demonstrate the best practice for multi-Region deployments using HashiCorp Terraform as infrastructure as code (IaC), and AWS CodeBuild , CodePipeline as continuous integration and continuous delivery (CI/CD) for consistency and repeatability of deployments into multiple AWS Regions and AWS Accounts. [hands on]

A couple of posts this weeks for those of you who are interested or follow Kubernetes. First up we have Jeremy Cowan who writes, Amazon EKS improves control plane scaling and update speed by up to 4x and shares some of the insights around how AWS has been able to optimise and speed up the performance of the Amazon EKS control plane, with the aim of making the EKS user experience even better.

The second post is a hands on tutorial from Akshit Khanna and Arun Thangaraj, where you will leverage several AWS services, including AWS App Mesh, Amazon Route 53, and Amazon EKS, to run a resilient, highly available application in two different regions. Read on if this sounds like something you want to try, in Run an active-active multi-region Kubernetes application with AppMesh and EKS

Quick updates

Transport Layer Security (TLS)

To respond to evolving technology and regulatory standards for Transport Layer Security (TLS), we will be updating the TLS configuration for all AWS service API endpoints to a minimum of version TLS 1.2. This update means you will no longer be able to use TLS versions 1.0 and 1.1 with all AWS APIs in all AWS Regions by June 28, 2023.

To find out more, read the post TLS 1.2 to become the minimum TLS protocol level for all AWS API endpoints


Amazon MemoryDB for Redis is now a Payment Card Industry Data Security Standard (PCI DSS) compliant service. MemoryDB is a fully managed, Redis-compatible, in-memory database that provides low latency, high throughput, and durability at any scale. You can now use MemoryDB to store sensitive payment card data with low latency and high throughput for use cases such as payment processing, mobile wallet, and payment fraud prevention that are subject to PCI DSS.


You can now bring your own development environment in a custom image to RStudio on Amazon SageMaker. RStudio on SageMaker is the industry’s first fully managed RStudio Workbench in cloud. You can quickly launch the familiar RStudio Integrated Development Environment (IDE), dial up and down the underlying compute resources without interrupting your work, and even switch to programming using Python on Amazon SageMaker Studio Notebooks. All your work, including code, datasets, repositories, and other artefacts are synchronised between the two environments. You can bring your current RStudio license to Amazon SageMaker at no additional charge to quickly get started.

RStudio on SageMaker already comes with a built-in image pre-configured with R programming and data science tools including SageMaker SDK, AWS CLI, AWS SDK, and Reticulate package for integration with Python-based interfaces. Starting today, you can register your own custom image with packages and tools of your choice, and make them available to all the users sharing the RStudio on SageMaker domain. Bringing your own custom image has several benefits. You can standardise and simplify the getting started experience for data scientists and developers by providing a starter base image, pre-configure the drivers required for connecting to data stores, or pre-install specialised data science software for your business domain.

Check out this blog post, Use a custom image to bring your own development environment to RStudio on Amazon SageMaker for more details of how this will work.

AWS Toolkit for Visual Studio

The AWS Toolkit for Visual Studio is an open source extension for Microsoft Visual Studio running on Microsoft Windows that makes it easier for developers to develop, debug, and deploy applications using Amazon Web Services, allowing you to get started faster and be more productive. Developers can now access Amazon CloudWatch Logs within Visual Studio using the AWS Toolkit for Visual Studio. Directly from the IDE, it is now possible to search and filter log groups, log streams, and events. Additionally, log groups can be accessed from their associated resources, and log events can be downloaded to a file.

The latest release of the toolkit includes several convenient CloudWatch logs features. Visual Studio users can list CloudWatch Log groups from the CloudWatch Logs node in the AWS Explorer. Individual log groups can be opened in a document tab, where you can view the log group’s streams, as well as export stream events to a local file. While viewing a log stream, you can search and filter log messages using keywords or phrases, such as "Exception" or "Error". You can also search using a time range, to see events that led up to and resulted from the error you were searching.
