If you are looking for new projects to try out, then this weeks projects include a very handy tool for Amazon EKS admins, a new experimental project that looks to use ChatGPT to manage your Amazon Web Services resources, a workshop on Generative AI on Amazon Web Services, a new tool that helps simplify how you can connect to RDS resources, a PHP library to help you verify your JWT tokens, and a great example application of how you can use Cedar and Amazon Verified Permissions. Great stuff. Also featured this week is content on popular open source technologies, which this week include Cedar, OpenSearch, Apache Spark, Apache Iceberg, Kubernetes, Apache Kafka, Amazon Amplify, Amazon Corretto, Grafana, Amazon ParallelCluster, PostgreSQL, Kubecost, Prometheus, Amazon Cloud Map MCS Controller, PyTorch and more! Also, be sure to check out the events section as there are a few events happening this week. ###### **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?trk=cndc-detail) and you will forever have my gratitude! ## **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: Aidan Steele, Rio Astamal, Cristian Magherusan-Stanciu, David Nalley, Mark Ryland, Vikas Bajaj, Daniel Aniszkiewicz, AJ, John Mille, Sunita Nadampalli, Ankith Gunapal, Cameron Senese, Imaya Kumar Jagannathan, Vikram Venkataraman, Vivek Gautam, Naresh Gautam, Harsha Tadiparthi, and Mikhail Vaynshteyn ### **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** ###### **ChatGPT-cloud-plugin** [ChatGPT-cloud-plugin](https://github.com/LeanerCloud/ChatGPT-cloud-plugin?trk=cndc-detail) is the latest project from our good friend, Cristian Magherusan-Stanciu, and is a new experimental project that one day, will help you manage your Amazon Web Services resources using ChatGPT. One to watch. ###### **lightsail-miab-installer** [lightsail-miab-installer](https://github.com/rioastamal/lightsail-miab-installer?trk=cndc-detail) is a user-friendly command-line tool from my colleague Rio Astamal, that will help you streamline the setup of [Mail-in-a-Box](https://github.com/mail-in-a-box/mailinabox?trk=cndc-detail) on Amazon Lightsail. I have featured [Mail-in-a-Box](https://github.com/mail-in-a-box/mailinabox?trk=cndc-detail) in previous newsletters, and this project provides everything you need to run a turn-key mail system. It uses lots of other open source projects and technologies (postfix, Dovecot, nginx, dns4, and lots more!). ###### **rdsconn** [rdsconn](https://github.com/aidansteele/rdsconn?trk=cndc-detail) is the latest project from Amazon Web Services Hero Aidan Steele, that makes connecting to an Amazon RDS instance inside a VPC from your laptop easier. It uses the recently launched EC2 Instance Connect to achieve this. This is something that I am going to try out as I do run a lot of RDS demo instances, and so I can see this being very handy indeed (good by ssh-tunnel) ** ###### kafka-connect-watcher** [kafka-connect-watcher](https://github.com/JohnPreston/kafka-connect-watcher?trk=cndc-detail) is a project from Amazon Web Services Community Builder John Mille, that will actively probe and monitor your Kafka connect clusters using the Connect API. It can report metrics to Amazon CloudWatch (Prometheus coming) using Amazon EMF to allow creating alerts and alarms. While that alone is pretty cool, John has also put together a blog post,[ Kafka Connect Watcher - actively monitor your clusters](https://dev.to/aws-builders/kafka-connect-watcher-actively-monitor-your-clusters-35ib?trk=cndc-detail), to help you get started. Awesome as always from John! ###### **cognito-token-verifier** [cognito-token-verifier](https://github.com/Internacionalweb/cognito-token-verifier?trk=cndc-detail) is a PHP library verifies that the signature of the JWT is valid, comes from a desired application, and that the token has not been tampered with or expired. ###### **eks-pod-information-collector** [eks-pod-information-collector](https://github.com/aws-samples/eks-pod-information-collector?trk=cndc-detail) This project was created to collect Amazon EKS resource information related to a specific POD such as Configurations/Specification, PV/PVC etc., logs (optional) etc. for troubleshooting Amazon EKS customer support cases. ###### **cdk-appflow** [cdk-appflow](https://github.com/cdklabs/cdk-appflow/?trk=cndc-detail) is a new Amazon CDK construct for Amazon Appflow, a centralised control hub for managing data integrations between third-party SaaS Applications and Amazon Web Services. The library is currently in tech preview, so if you do try it out you can provide feedback through the usual mechanisms in GitHub. #### **Demos, Samples, Solutions and Workshops** ###### **avp-petstore-sample** [avp-petstore-sample sample](https://github.com/aws-samples/avp-petstore-sample?trk=cndc-detail) web application demonstrates authentication and policy-based authorization of diffrent user types to an imaginary Pet Store web app. This application uses Amazon Cognito for authentication and uses Cedar policies and Amazon Verified Permissions for policy-based authorisation, the application uses Amplify platform to accelerate deployment and provisioning of backend resources. ![PetStore-test.gif](https://dev-media.amazoncloud.cn/cfcd4b6bea05479f82c0779db1135b2a_PetStore-test.gif "PetStore-test.gif") ###### **generative-ai-immersion-day** [generative-ai-immersion-day](https://github.com/aristsakpinis93/generative-ai-immersion-day?trk=cndc-detail) it seems impossible to avoid Generative AI, so if you are looking to dive deeper into this topic on Amazon Web Services, check out this workshop that is set up following the popular Amazon Web Services Immersion Day format and provides guidance on how to get started with Generative AI on Amazon Web Services. #### **Amazon Web Services and Community blog posts** ###### **Community roundup** Amazon Web Services Community Builder Daniel Aniszkiewicz has put together a great post on Cedar, [Authorization and Cedar: A New Way to Manage Permissions - Part I](https://dev.to/aws-builders/authorization-and-cedar-a-new-way-to-manage-permissions-part-i-1nid?trk=cndc-detail) which is the first of a series of articles Daniels is putting together where he will share how to create an authorisation decisions system for an e-commerce platform scenario. This looks like one to watch folks. [Fast and Efficient Search with OpenSearch and MinIO](https://blog.min.io/search-with-opensearch-and-minio/?trk=cndc-detail) from AJ also caught my eye last week, that looks at how you can leverage MinIO as a storage backend for OpenSearch. ###### **PyTorch** In the post, [Optimized PyTorch 2.0 Inference with Amazon Web Services Graviton processors](https://pytorch.org/blog/optimized-pytorch-w-graviton/?trk=cndc-detail), Sunita Nadampalli and Ankith Gunapal dive deep into benchmarking PyTorch inference against a number of different Amazon Web Services instance types. I am not going to give anything away, if you want answers, then read the post! ![im3.png](https://dev-media.amazoncloud.cn/49015a167031463b8a96beceffbe5135_im3.png "im3.png") ###### **Kubernetes** More fabulous* Kubernetes posts this week. Kickings this off this week we have Cameron Senese who put together,[ Kubernetes Multi-Cluster Service Discovery using Open Source Amazon Cloud Map MCS Controller](https://aws.amazon.com/cn/blogs/opensource/kubernetes-multi-cluster-service-discovery-using-open-source-aws-cloud-map-mcs-controller/?trk=cndc-detail). Open source tooling exists to help manage multi-cluster workloads, including the upstream Kubernetes Multi-Cluster Services API (mcs-api), and the open source Amazon Web Services Cloud Map MCS Controller (MCS-Controller). In this post, Cameron provides an overview of Kubernetes multi-cluster workload management, the mcs-api, and the MCS-Controller which is the Amazon Web Services open source implementation of the mcs-api. [hands on] ![AWS-cloud-map-controller-solution-diagram.png](https://dev-media.amazoncloud.cn/5b1e04eb79474515b7ef54af185921d6_AWS-cloud-map-controller-solution-diagram.png "AWS-cloud-map-controller-solution-diagram.png") Next up is a collaboration between Imaya Kumar Jagannathan and Vikram Venkataraman, who have put together [Multi-cluster cost monitoring for Amazon EKS using Kubecost and Amazon Managed Service for Prometheus](https://aws.amazon.com/cn/blogs/containers/multi-cluster-cost-monitoring-using-kubecost-with-amazon-eks-and-amazon-managed-service-for-prometheus/?trk=cndc-detail). In this hands on post, you will learn how you can use Kubecost to monitor multi-cluster Amazon EKS environments using Amazon Managed Service for Prometheus as the metrics store so you don’t have to worry about managing your own infrastructure to store Kubecost data. [hands on] ![Large-scale-option.png](https://dev-media.amazoncloud.cn/929ea77db0314b93a805bac4eafd475c_Large-scale-option.png "Large-scale-option.png") Finally, make sure you check under Quick Updates Amazon EMR on EKS section for a couple of other useful new features and capabilities recently launched. *we really need to use this word more in blogs!、 ###### **Apache Iceberg** In [Accelerate data science feature engineering on transactional data lakes using Amazon Athena with Apache Iceberg](https://aws.amazon.com/cn/blogs/big-data/accelerate-data-science-feature-engineering-on-transactional-data-lakes-using-amazon-athena-with-apache-iceberg/?trk=cndc-detail) Vivek Gautam, Naresh Gautam, Harsha Tadiparthi, and Mikhail Vaynshteyn review the benefits of using Athena with the Apache Iceberg open table format and how it simplifies common feature engineering tasks for data scientists. [hands on] ###### **Apache Kafka** [Multi-tenancy Apache Kafka clusters in Amazon MSK with IAM access control and Kafka Quotas – Part 1](https://aws.amazon.com/cn/blogs/big-data/multi-tenancy-apache-kafka-clusters-in-amazon-msk-with-iam-access-control-and-kafka-quotas-part-1/?trk=cndc-detail) is the first of a two part series from Vikas Bajaj that explains the concepts of how to enforce Kafka quotas in MSK multi-tenant Kafka clusters while using Amazon Identity and Access Management (IAM) access control for authentication and authorisation. [hands on] ![BDB-2595-MSKQuotas-no-zero-trust-msk-cluster.jpg](https://dev-media.amazoncloud.cn/8687ee97705f4f72b9f54c8eaec11b6c_BDB-2595-MSKQuotas-no-zero-trust-msk-cluster.jpg "BDB-2595-MSKQuotas-no-zero-trust-msk-cluster.jpg") ###### **Other posts and quick reads** • [Introducing Industry Blueprints for Data & AI to Help Amazon Web Services Partners Accelerate Solution Development ](https://aws.amazon.com/cn/blogs/apn/introducing-industry-blueprints-for-data-ai-to-help-aws-partners-accelerate-solution-development/?trk=cndc-detail)introduces Amazon Web Services Industry Blueprints for Data & AI (Preview), an open-source initiative that offers a collection of building components, to accelerate how industry verticals are able to turn-data-to-insights needs ![Industry-Blueprints-Data-AI-1.png](https://dev-media.amazoncloud.cn/b311788d80d44ebdb3ce5ab67df62d8b_Industry-Blueprints-Data-AI-1.png "Industry-Blueprints-Data-AI-1.png") • [Enable remote reads from Azure ADLS with SAS tokens using Spark in Amazon EMR](https://aws.amazon.com/cn/blogs/big-data/enable-remote-reads-from-azure-adls-with-sas-tokens-using-spark-in-amazon-emr/?trk=cndc-detail) demonstrates how to set up quick, constrained, and time-bound authentication and authorisation to remote data sources in Azure Data Lake Storage (ADLS) using a shared access signature (SAS) when running Apache Spark jobs via EMR Notebooks attached to an EMR cluster [hands on] ![BDB-2904-01-arch.png](https://dev-media.amazoncloud.cn/8651b1dceffd4e10b1a79afffbeefb01_BDB-2904-01-arch.png "BDB-2904-01-arch.png") •[ Testing Amazon Lambda functions with Amazon SAM remote invoke](https://aws.amazon.com/cn/blogs/compute/testing-aws-lambda-functions-with-aws-sam-remote-invoke/?trk=cndc-detail) looks at a new feature within Amazon SAM that enables developers to invoke a Lambda function in the Amazon Cloud from their development environment [hands on] • [Encrypt Amazon RDS for PostgreSQL and Amazon Aurora PostgreSQL database with minimal downtime](https://aws.amazon.com/cn/blogs/database/encrypt-amazon-rds-for-postgresql-and-amazon-aurora-postgresql-database-with-minimal-downtime/?trk=cndc-detail) provides a hands on guide that walks you through how to convert an unencrypted RDS for PostgreSQL database to an encrypted database with minimum downtime [hands on] • [Customize Slurm settings with Amazon ParallelCluster 3.6](https://aws.amazon.com/cn/blogs/hpc/customize-slurm-settings-with-aws-parallelcluster-3-6/?trk=cndc-detail) looks at how you can customise the settings for the Slurm scheduler in your cluster configuration file to tweak the behaviour of your cluster to meet your specific use cases [hands on] • [Optimize the cost of your Amazon ElastiCache for Redis workloads](https://aws.amazon.com/cn/blogs/database/optimize-the-cost-of-your-amazon-elasticache-for-redis-workloads/?trk=cndc-detail) explores the top five recommendations on how to optimize the cost when running ElastiCache for Redis workloads using native ElastiCache features ![DBBLOG2805_image001-1024x576.png](https://dev-media.amazoncloud.cn/9b31edbc8b3b4e9686484849587734aa_DBBLOG2805_image001-1024x576.png "DBBLOG2805_image001-1024x576.png") ###### **Case Studies** • [How Quora modernized MLOps on Amazon EKS to improve customer experience with scalable ML applications](https://aws.amazon.com/cn/blogs/containers/how-quora-modernized-mlops-on-amazon-eks-to-improve-customer-experience-with-scalable-ml-applications/?trk=cndc-detail) looks at how Quora modernised its MLOps platform on Amazon EKS.

Developers can now test the latest OpenJDK community code and bug fixes without waiting for the next quarterly release. Binaries for Corretto 8, 11, 17, and the latest Feature Release, Corretto 20, are being built combining the latest stable and development code from the next release of the OpenJDK projects. Early Access builds of upcoming releases will also be available prior to GA. Release and fast-debug builds, which contain assertions on JVM state and correctness, are available. In addition, we will be sharing early builds of experimental projects in binary form, for evaluation, validation and testing. For example, right now we have the Generational Shenandoah and Lilliput projects back ported to Corretto 17. The Generational Shenandoah Garbage Collector adds generational collection capabilities and aims to eventually reduce GC pauses below 1 ms for large-heap, high-throughput applications. The Lilliput project reduces the size of Java Object headers from 96 bytes down to 64 bytes, with a future goal of 32 bytes, which will reduce memory pressure and can result in fewer/shorter GC pauses. Along with the Corretto binaries, corresponding functional and integration test results are available so that anyone can see what fixes and issues are still present in the build. Nightly Builds are for evaluation only and should not be relied on for production use. ###### **Amazon CDK** Alex Pulver shared [this post](https://www.linkedin.cn/incareer/home?trk=cndc-detail) and looks at a new app-level bootstrap experimental feature for your Amazon CDK stacks. You can read more in the docs about a[pp-staging-synthesizer-alpha module](https://docs.aws.amazon.com/cdk/api/v2/docs/app-staging-synthesizer-alpha-readme.html?trk=cndc-detail) ###### **Amazon Amplify** Amazon Amplify announced the UI Builder Figma plugin last week, empowering design and development teams to seamlessly collaborate within a Figma file. Use this plugin with the Amplify UI kit to easily theme your components, upgrade to new UI kit versions, and generate and preview React code from your designs directly in Figma. ###### **Grafana** Amazon Managed Grafana now supports Trace Analytics with the OpenSearch Grafana data source plugin, in addition to the existing support for Log Analytics. Amazon Managed Grafana is a fully managed service for Grafana, a popular open-source analytics platform that enables you to query, visualise, and alert on your metrics, logs, and traces. OpenSearch is an open-source search and analytics engine for use cases such as log analytics, observability, real-time application monitoring, and clickstream analysis that is also offered as a fully managed Amazon OpenSearch Service. With this release, you can analyse your logs and trace data stored in OpenSearch, alongside metrics from your other data sources, in a single view in Amazon Managed Grafana, thus simplifying the correlation and analysis of these data points. The newly added trace views show the timeline of traces and allow you to drill down into spans, helping you to isolate the source of performance problems and diagnose their root cause directly from your Amazon Managed Grafana workspace. ###### **Amazon EMR on EKS** A couple of quick updates this week. First up was news that Volcano and Apache Yunikorn have been added as job schedulers when running EMR on EKS using Spark operator and spark-submit. Amazon EMR on EKS enables customers to run open-source big data frameworks such as Apache Spark on Amazon EKS. Using a custom job scheduler for Spark jobs enables fine-grained capacity management and faster pod provisioning at scale. The default Kubernetes scheduler handles the placement of individual pods, while maintaining constraints such as available capacity, resource requests and limits, and node affinity. However, it does not support scheduling based on jobs. With this new feature, customers have the option to use Apache Yunikorn and Volcano to schedule EMR on EKS Spark jobs with Spark operator and spark-submit. Customers can leverage features like gang scheduling, queue management, preemption, fair-share scheduling in these schedulers, which helps to deliver high scheduling throughput and optimised capacity. We also announced the ability to control container log rotation when running Apache Spark jobs in EMR on EKS. Amazon EMR on EKS enables customers to run open-source big data frameworks such as Apache Spark on Amazon EKS. Customers can now enable container log rotation to avoid excessive log files impacting pod execution. For long running Spark jobs like Spark streaming, customers can run into low disk space issues which may cause performance degradation or job failure, and might get forced to manually delete logs from Kubernetes pods. With this release, customers can now enable container log rotation and customise how many log files will be kept in the Spark driver/executor pods, including setting the maximum size of each log file. ###### **MySQL** Amazon Relational Database Service (Amazon RDS) for MySQL now supports MySQL minor versions 5.7.42 and 8.0.33. 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 bug fixes, performance improvements, and new functionality added by the MySQL community. You can leverage automatic minor version upgrades to automatically upgrade your databases to more recent minor versions during scheduled maintenance windows. ###### **MariaDB** Amazon Relational Database Service (Amazon RDS) for MariaDB now supports MariaDB minor versions 10.6.13, 10.5.20, 10.4.29, and 10.3.39. We recommend that you upgrade to the latest minor versions to fix known security vulnerabilities in prior versions of MariaDB, and to benefit from the bug fixes, performance improvements, and new functionality added by the MariaDB community. You can leverage automatic minor version upgrades to automatically upgrade your databases to more recent minor versions during scheduled maintenance windows. ###### **Software Bill of Materials export** Whilst not open source, I thought I would share this update as it might help folk provide Software Bill of Materials (SBOM) files within their Amazon Web Services workloads. Announced at re:Inforce last week, Amazon Inspector now offers the ability to export a consolidated Software Bill of Materials (SBOMs) for all Amazon Inspector monitored resources across your organisation in industry standard formats, including CycloneDx and SPDX. With this new capability, you can use automated and centrally managed SBOMs to gain visibility into key information about your software supply chain. This includes details about software packages used in the resource, along with associated vulnerabilities. After Amazon Inspector exports the SBOMs to an Amazon S3 bucket, you have the option to download the SBOM artefacts and use Amazon Athena or Amazon QuickSight to analyse and visualise software supply chain trends. This capability in Amazon Inspector is available with a few clicks in the Amazon Inspector console or using Amazon Inspector APIs. #### **Videos of the week** **Amazon Web Services re:Inforce 2023 - Security in the Open: OSS and Amazon Web Services** re:Inforce is a security learning conference featuring Amazon Web Services experts and industry-leading customers. One of the highlights for me was the leadership session on open source security, where David Nalley and Mark Ryland provided a very nice overview of how we think of this space and some of the things we are working with the community on. This is a must watch session in my view. YouTube video:https://youtu.be/kMY8gGmWfAI ###### **Finding Your Way With CDK** Recorded at the Amazon Web Services Perth UG Meetup on June 23rd, James Vulling provided an in depth session on everything you needed to know about Amazon CDK. YouTube video:https://youtu.be/LmdZLAPdLcs ###### **Build on Open Source** For those unfamiliar with this show, Build on Open Source is where we go over this newsletter and then invite special guests to dive deep into their open source project. Expect plenty of code, demos and hopefully laughs. We have put together a playlist so that you can easily access all (sixteen) of the episodes of the Build on Open Source show. B[uild on Open Source playlist.](https://www.twitch.tv/collections/a7OU6drfRxfAag?trk=cndc-detail) We are currently planning the third series - if you have an open source project you want to talk about, get in touch and we might be able to feature your project in future episodes of Build on Open Source. ## **Events for your diary** If you are planning any events in 2023, either virtual, in person, or hybrid, get in touch as I would love to share details of your event with readers. **Apache Kafka London Sainsbury's HQ, 33 Holborn, London EC4A1AA, 26th June 2023 5.45 - 8:30 pm** OSO are teaming up with Sainsbury's, special sponsor for this event, to deliver an exciting program of talks that include Amazon Web Services Community Builder John Mille whose talk, Kafka enterprise strategy to evolve with demand, will go over insights of early days, lessons learnt and successful governance patterns which made the onboarding smoother as time went. He will also review the different tooling involved in making this journey successful not only for business but for developers, along with leveraging Kafka community driven projects such as Kafka Connect. If you are about and want to learn more about Apache Kafka, there is nothing better than attending a user group. Head over to the meetup page and sign up:[ IN-PERSON: Kafka Enterprise Strategies: Best Practices](https://www.meetup.com/login/?returnUri=https%3A%2F%2Fwww.meetup.com%2Fapache-kafka-london%2Fevents%2F293908569?trk=cndc-detail) **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?
