## June  19th, 2023 - Instalment #161

Welcome to #161 of the AWS open source newsletter, and another week for fresh, new open source projects and code for you to practice your four freedoms. This weeks projects include tools that will help you create temporary elevated credentials, a new Java library that provides methods for encrypting and decrypting cryptographic materials, an AWS DynamoDB wrapper for Node/TypeScript developers, and a solution to help you find and visualise data assets. We also have some great demo code that shows you how you can deploy an AWS managed Active Directory, Keycloak, a tool to help automate the creation of transcripts for your prod casts, and a great project that helps you to build continuous deployment pipelines following current good practices.

This weeks newsletter is also filled with lovely content on some of your favourite open source projects, featuring Falcon, Keycloak, Cedar, FreeRTOS, Apache Airflow, Apache Spark, Apache Hudi, Apache Iceberg, and Delta Lake, Apache Flink, OpenChatkit, Pinniped, Kubecost, Karpenter, ONNX, Apache Kafka, Babelfish for Aurora PostgreSQL, AWS Amplify, Next.js, OpenSearch, Flux, ArgoCD, KVM, and more.

I have added a few events that are happening this week and next, so make sure you do not miss those too.

**Feedback**

Before you dive in however, I need your help!  Please please please take 1 minute to [complete this short survey](https://pulse.buildon.aws/survey/PJRTOUMK) and bask in the warmth of having helped improve how we support open source.

### 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 Krohn, Marcell Jobs, Nicholas Saenz Julienne, Anel Orazgaliyeva, Carlos Santana, Sai Vennam, Suraj Narwade, James McIntyre, Siva Guruvareddiar, Elamaran Shanmugam, Re Alvarez-Parmar, Adam McLean, Ashok Srirama, Hemanth AVS, Giacomo Margaria , Lotfi Mouhib, Hamza Mimi, Vikram Elango, Andrew Smith, Dhawalkumar Patel, Nir Tsruya, and Ankit Gupta, Daniel Arenhage, Kalaiarasu M, Shana Schipers, Ian Meyers, Carlos Rodrigues, Damon Cortesi, Vincent Beck, Tony Smith, Darin McAdams, Daniel Bass, Lee Gilmore, and  Johannes Koch.

### 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

**iam-identity-center-team**

[iam-identity-center-team](https://aws-oss.beachgeek.co.uk/2xr) this repository contains the source code for the deploying temporary elevated access management (TEAM) application. TEAM is an open source solution that integrates with AWS IAM Identity Center and allows you to manage and monitor, time-bound elevated access to your multi-account AWS environment at scale. The solution is a custom application that allows users to request access to an AWS account only when it is needed and only for a specific period of time. Once the time period has elapsed, elevated access is automatically removed. Very nice project with great documentation.

![overview of TEAM architecture](https://d3f99z5n3ls8r1.cloudfront.net/images/architecture/archi.png)

**aws-cryptographic-material-providers-library-java**

[aws-cryptographic-material-providers-library-java](https://aws-oss.beachgeek.co.uk/2xs) provides methods for encrypting and decrypting cryptographic materials used in higher level client side encryption libraries. The AWS Cryptographic Material Providers Library abstracts lower level cryptographic materials management of encryption and decryption materials. It uses cryptographic best practices to protect the data keys that protect your data. The data key is protected with a key encryption key called a wrapping key or master key. The encryption method returns the data key and one or more encrypted data keys. Supported libraries use this information to perform envelope encryption. The data key is used to protect your data, and the encrypted data keys are stored alongside your data so you don't need to keep track of the data keys separately. You can use AWS KMS keys in AWS Key Management Service(AWS KMS) as wrapping keys. The AWS Cryptographic Material Providers Library also provides APIs to define and use wrapping keys from other key providers.

> **Note** The AWS Cryptographic Material Providers Library is released as a developer preview and is subject to change. The current release is not intended to be used in production environments.

**tinymo**

[tinymo](https://aws-oss.beachgeek.co.uk/2xl) is a nice AWS DynamoDB wrapper for Node/TypeScript developers. It simplifies constructing DynamoDB's JSON-based command inputs within your code, and should make the experience a lot less annoying. Repo has plenty of examples to get you started too.

**cdk-aws-ad-connect**

[cdk-aws-ad-connect](https://aws-oss.beachgeek.co.uk/2ww) from AWS Community Builder and Ambassador David Krohn and Marcell Jobs that makes it easy to deploy and configure an Active Directory Connector using AWS Step Functions.

**sensitive-data-protection-on-aws**

[sensitive-data-protection-on-aws](https://aws-oss.beachgeek.co.uk/2xq) this solution allows enterprise customers to create data catalogs, discover, protect, and visualise sensitive data across multiple AWS accounts. The solution eliminates the need for manual tagging to track sensitive data such as Personal Identifiable Information (PII) and classified information.

![example of dashboard from this solution](https://github.com/awslabs/sensitive-data-protection-on-aws/blob/main/docs/en/images/portal-summary-256.png?raw=true)

### Demos, Samples, Solutions and Workshops

**cicdonaws-example-projects**

[cicdonaws-example-projects](https://aws-oss.beachgeek.co.uk/2xk) - AWS Hero Johannes Koch shares with you a new project he is working on that shows you how to implement a simple, end to end CI/CD pipelines that contains all of the steps that follow "best practices". With the project, Johannes wants to be able to give Builders around the globe the possibility to understand the difference between certain CI/CD tools while at the same time following best practices.

![overview of the project sample app architecture](https://github.com/Lock128/cicdonaws-example-projects/blob/main/docs/diagrams/aws_architecture.png?raw=true)

He is looking for feedback on his project, so make sure you check it out. He has also put together a helpful video to walk you through the different components.

**active-directory-on-aws-cdk**

[active-directory-on-aws-cdk](https://aws-oss.beachgeek.co.uk/2xo) this is a sample repo that will help you deploy an AWS managed Active Directory server (with additional supporting resources and configurations) using AWS CDK. I put this together as I could not find one, and I needed it for a demo I am putting together. I also put together a blog post that walks you through using it. Check that out here, [Using CDK to deploy AWS managed Active Directory](https://dev.to/aws/using-cdk-to-deploy-aws-managed-active-directory-35ci)

**keycloak-aws**

[keycloak-aws](https://aws-oss.beachgeek.co.uk/2v1) this repo provides a working example of how you can use the keycloak-cdk construct to deploy a later version of Keycloak. Most of the solutions out there seem to work for versions of Keycloak v16 or older, and I needed to bootstrap a newer version. I put together a post that provides a walk through of how you can use it. Let me know what you think, and read the post here, [Integrating Keycloak as my Identity Provider for IAM Identity Centre: Part one, deploying Keycloak on AWS](https://dev.to/aws/integrating-keycloak-as-my-identity-provider-for-iam-identity-centre-part-one-deploying-keycloak-on-aws-2ol1) (with a follow on part [here](https://dev.to/aws/integrating-keycloak-as-my-identity-provider-for-iam-identity-centre-part-two-configuring-keycloak-as-my-identity-provider-1n0k))

**podwhisperer**

[podwhisperer](https://aws-oss.beachgeek.co.uk/2xp) A completely automated podcast audio transcription workflow with super accurate results (according to the developers ;-) This project uses AWS SAM with nested stacks to deploy a number of tools, and the solution uses a number of additional services such as OpenAI Whispher and Amazon Transcribe. Check out the architecture.

### AWS and Community blog posts

**Community roundup**

I love exploring the many and varied posts that the community creates, and last week there was so many great that I enjoyed reading. Kicking off with an open source project I am spending time getting to know, Cedar. Open Source is all about scratching that itch, and Darin McAdams posted [Why was Cedar created? ](https://aws-oss.beachgeek.co.uk/2y3) and explores why Cedar was created. Keeping with the Cedar theme, Daniel Bass has put together a very nice post, [Implementing Role-Based Access Control (RBAC) with AWS’ Cedar](https://aws-oss.beachgeek.co.uk/2y2), that provides a nice overview of how (and why) should you implement Role Based Access Control (RBAC) using the Cedar policy engine.

I love hacking around with various IoT devices, and have various ESP32 and other devices lying around so I was super interested in reading Tony Smith's post, [Achieving Unbrickable MCU FOTA for your FreeRTOS-powered Firmware: The Microvisor IoT Approach](https://aws-oss.beachgeek.co.uk/2xt) showing how you can use Twilio Microvisor together with FreeRTOS to reduce the risk of bricking devices during over-the-air (OTA) updates.

![overview of twilio microvisor](https://freertos.org/fr-content-src/uploads/2023/05/microvisor-zone.png)

If you are using Managed Workflows for Apache Airflow (MWAA) and integrating it with AWS Secrets manager, then this post, [Setting up AWS secrets backends with Airflow in a cost-effective way](https://aws-oss.beachgeek.co.uk/2xu), is an essential read from Vincent Beck. The post dives deep into how the integration works, and takes a look at how you can optimise your costs. On a related note, if you missed [How Apache Airflow Better Manages Machine Learning Pipelines](https://aws-oss.beachgeek.co.uk/2xw) that was published on The New Stack last week, then check it out as it speaks with a number of the AWS folks working upstream in the Apache Airflow community to help improve the Apache Airflow user experience.

**Apache Spark**

Damon Cortesi has put together a very nice post, [Deploy Serverless Spark Jobs to AWS Using GitHub Actions](https://aws-oss.beachgeek.co.uk/2xv), that shows how to deploy an end-to-end Spark ETL pipeline to Amazon EMR Serverless with GitHub Actions.

**Apache Hudi, Apache Iceberg, and Delta Lake**

Apache Hudi, Apache Iceberg, and Delta Lake are open-source transactional table formats (or open table formats) can help you solve advanced use cases around performance, cost, governance, and privacy in your data lakes. In the post, [Choosing an open table format for your transactional data lake on AWS](https://aws-oss.beachgeek.co.uk/2x2) Shana Schipers, Ian Meyers, and Carlos Rodrigues provide a super helpful guide shows how open-source transactional table formats (or open table formats) can help you solve advanced use cases around performance, cost, governance, and privacy in your data lakes. These table format each have their own unique strengths for specific requirements, so it is important to determine which requirements and use cases are most crucial and select the table format that best meets those needs. This post helps you with that, so an essential read this week.

**Apache Flink**

In the post, [How Klarna Bank AB built real-time decision-making with Amazon Kinesis Data Analytics for Apache Flink](https://aws-oss.beachgeek.co.uk/2x6) Nir Tsruya from Klarna Bank AB, and Ankit Gupta, and Daniel Arenhage from AWS look at a reference architecture for real-time queries and decision-making on AWS using Amazon Kinesis Data Analytics for Apache Flink, and looks at why  the Klarna Decision Tooling team selected Apache Flink for their first real-time decision query service.

![apache flink at klarna reference architecture](https://d2908q01vomqb2.cloudfront.net/b6692ea5df920cad691c20319a6fffd7a4a766b8/2023/04/14/bdb2880-architecture-1.png)

A late addition to the newsletter was this post from data engineer Kalaiarasu M who wrote, [RealTime Data Processing — Integrate Kafka with Flink To S3](https://aws-oss.beachgeek.co.uk/2xy) that explores how to leverage Apache Flink and Python to push data to Amazon S3, where you have an Apache Kafka data source. [hands on]

### Quick updates

**OpenSearch**

A couple of important updates this week.

First up was news that OpenSearch 2.8 is now here. James McIntyre shared all the details in his post, [OpenSearch 2.8 is here!](https://aws-oss.beachgeek.co.uk/2xz). This release brings a host of new features and enhancements and experimental functionality including new tools for machine learning, search, and observability workloads and several enhancements to better manage your indexes and data.

OpenSearch now has a [performance benchmarking page](https://aws-oss.beachgeek.co.uk/2xj). This page displays the results of ongoing performance testing for recent and upcoming versions of the OpenSearch software. You can view key performance metrics across different workloads with the dashboard visualisations below.

**Apache Spark**

Amazon Athena for Apache Spark is a feature of Amazon Athena lets you run interactive analytics on Apache Spark in under a second to analyse petabytes of data. 

Amazon Athena for Apache Spark now allows you to use your own Java libraries and customise the Spark configurations for your Spark workloads. You can use Java libraries as custom JARs with Athena Spark to analyse data from multiple sources or use functions in custom jars for more flexibility with calculations.

Amazon Athena for Apache Spark now supports open-source data lake storage frameworks Apache Hudi 0.13, Apache Iceberg 1.2.1, and Linux Foundation Delta Lake 2.0.2. These frameworks simplify incremental data processing of large data sets using ACID (atomicity, consistency, isolation, durability) transactions and make it simpler to store and process large data sets in your data lakes.

**kubectl-eks**

[kubectl-eks](https://aws-oss.beachgeek.co.uk/203) this project from AWS Community Builder Suraj Narwade, was featured in a previous newsletter last year ( [#125](https://dev.to/aws/aws-open-source-news-and-updates-125-ein) ) had a new release last week (v.0.3.0). Check the docs for the changes and new features added.

**AWS Neuron**

**CNCF Maintainer Circle - Community Management**
**June 28th, 2023 @ 10:00am PT / 17:00 UTC**

Managing a project is hard work. Maintainers are expected to wear many hats. Defining those hats early on can help a project grow and ultimately be sustainable enough to not rely on a few maintainers to do it all. Let’s deep dive in one role around - community and contributor management.

In this session, we will discuss strategies on how to build out strategy around intentional community roles, groups, and more so you aren’t doing everything. What’s everything?

* Creating, maintaining, and moderating mailing lists, slacks, forums, and more
* Recruiting and onboarding new contributors: outreach, their documentation, workflows, and processes
* Maintaining current contributors: swag, recognition programs, events, and more
* Social media
* User adoption strategies and operations
* Governance operations
* Website updates
* Documentation

Sounds interesting and very useful right? Check out more and add this to your calendar by [checking out the event page](https://aws-oss.beachgeek.co.uk/2y1)
