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: Ethan Steininger, Stephen Said, Paul Villena, Vishwanatha Nayak, Brian Beach, Ran Isenberg, Jayesh Vartak, Allen Helton, James Eastham, Julian Wood and John Jackson.
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.
sls-mentor is an open source tool that analyses the configuration of your AWS resources against best practice rules, helping you to remove before they occur, and optimises your app’s performances and costs. Check out the blog post sls-mentor: your serverless quality teacher has arrived! where Pierre Chollet provides more info as to the origins of why this project was created, walks you through some of its capabilities, and then looks forward to what they are hoping to do next. Well worth checking out.
subnet-watcher is a neat tool that monitors the remaining free IP addresses in AWS VPC subnets (both public and private) using some CloudWatch custom metrics. It also sets up alerts to provide complete visibility on your VPC CIDR IP space. Hat Tip to Corey Quinn who shared this tool in his weekly AWS Newsletter.
aws-cdk-web-administered-apps this looks like it is going to help a lot of folk automate the deployment of well known open source software. This CDK+Python project is designed to support the web administered app model, where the admin interface is hosted within the same codebase as the front-end application. To achieve this outcome more securely, this project creates two groups of server hosts - one with admin access and one with only read access. This enables you to restrict all write operations to a server (or servers) that can only be accessed from specific allowed IP addresses. Comes with a couple of examples (Wordpress and Node-RED) to help you see how this works.
serverless-newsletter-app provides a complete Newsletter application that you can deploy yourself, leveraging AWS serverless services and SendGrid. AWS Hero Allen Helton shares his story in hist post, How I Built An Open Source Serverless Newsletter Platform. In it he writes how he came to build this open source project, and how you can use it to create your own Newsletter app. Very cool indeed.
slapo Slapo is a schedule language for progressive optimisation of large deep learning model training. Large deep learning models demonstrate dominating model accuracy on a range of tasks in NLP and CV, but it is hard to train the model efficiently while preserving the usability. Slapo aims to address this tension through separation of concerns. Slapo decouples model execution from definition, enabling developers to use a set of schedule primitives to convert a PyTorch model for common model training optimizations without directly changing the model itself.
update-aws-ip-ranges AWS publishes a list of it's IP address ranges (you can see the list here) This project creates Lambda function that automatically create or update AWS resource with AWS service's IP ranges from that ip-ranges.json file. You can configure which service and region to get range. You can also configure to which resources you want to create or update with those ranges. Use cases include allowing CloudFront requests, API Gateway requests, Route53 health checker and EC2 IP range (which includes AWS Lambda and CloudWatch Synthetics). The resources are created or updated in the region where the CloudFormation stack is created.
emr-spark-benchmark This repository provides a general tool to benchmark Spark performance on Amazon EC2 and Amazon EMR. The repos use an open source tool Flintrock to launch EC2 based Apache Spark clusters. If you want to baseline or compare how your Apache Spark performs, why not give this repo a try.
unlock-mainframe-data-files-on-aws This solution is designed to help you unlock legacy mainframe data by migrating data files from mainframe systems to AWS. The solution involves transferring data from mainframe datasets, converting it into a CSV format, and then storing the data in AWS.
axios-based-http-testing-tool Axios is a simple promise based HTTP client for the browser and node.js. This repo provides everything you need to help you deploy an axios based HTTP testing tool solution on AWS.
Demos, Samples, Solutions and Workshops
aws-iot-with-privatelink The goal of this project is to create IOT private link for customer who wants to send data from IoT device securely through private network without using public internet. The repo contains detailed breakdown of how this is achieved, and you can try it for yourself as they have a nice simulator to help you kick the tyres.
serverless-smart-streaming-engine this repo is for football fans (especially if you support Tottenham Hotspurs), and is a demo that shows how you can use CDK and amplify to build a streaming service with a smart backend that analyse the streaming media using a AI/ML service.
In this particular demo, it sends a soccer game that Tottenham plays, generate clips, and services only clips that Son Heung-min appears. (other teams and players would work). Make sure you check the demo clips in the repo. Very cool.
amazon-personalize-online-recommendations-with-google-tag-manager this repo provides some help to get you started working with Amazon Personalize, and AWS service that allows developers to quickly build and deploy curated recommendations and intelligent user segmentation at scale using machine learning (ML). If you are using Google Tag Manager (GTM) then see how you can integrate that date to create more personalised recommendations for your customers.
AWS and Community blog posts
If you are looking to dive into data lineage, an increasingly important area of your data governance strategy, then read on as this post is for you. OpenLineage is an open source project provides a technology-agnostic metadata model for capturing data lineage and integrates with widely used tools, including Apache Airflow, the topic for this blog post. In the post, Automate data lineage on Amazon MWAA with OpenLineage, Stephen Said, Paul Villena, and Vishwanatha Nayak show you how you can get started, using Marquez, an open-source metadata service for collection and visualisation of data lineage with support for the OpenLineage standard. [hands on]
We have a couple of great posts this week for OpenSearch fans.
Starting us off we have Ethan Steininger, who has written this post, Searching PDFs in S3 Using OpenSearch and Tika where he shows you a hands on guide in how to build a Python script that is able to search the contents of PDF files in an Amazon S3 bucket using Apache Tika and OpenSearch. Apache Tika is an open source project that helps you extract data from files, and in this tutorial the focus is on searching PDFs. Very nice little project. [hands on]
Next up we have Introducing identity and access control for OpenSearch from Peter Nied who explores the current and future direction of the OpenSearch security model. This direction presents a significant departure from the current security model, but these OpenSearch security features will help it be more efficient, more reliable, and simply easier and more enjoyable to work with. As OpenSearch is an open source project, they are currently inviting folk to share there views and comments, so check out the blog post for more details.
A couple of posts featuring AWS CDK this week. Kicking off with, Manually Approving Security Changes in CDK Pipeline Brian Beach provides a nice overview of how to add a manual approval to AWS Cloud Development Kit (CDK) Pipelines to confirm security changes before deployment. With this solution, when a developer commits a change, CDK pipeline identifies an IAM permissions change, pauses execution, and sends a notification to a security engineer to manually approve or reject the change before it is deployed. [hands on]
Following that we had AWS Community Builder (and Build on Open Source guest) Ran Isenberg put together Build AWS Lambda Layers with AWS CDK giving you a gentle introduction into AWS Lambda layers and then how you can build your own using Docker and AWS CDK.
If you are self managing Kubernetes, this post is for you. Jayesh Vartak looks at how to use pod priority and dummy pods that have a pause container to eliminate or minimise the time required for provisioning the worker nodes during scaling in hist post, Eliminate Kubernetes node scaling lag with pod priority and over-provisioning [hands on]

Videos of the week
AWS SAM - Building Java Serverless applications
The AWS Serverless Application Model (AWS SAM) is an open-source framework that helps to build Serverless applications on AWS. It provides a command-line interface (CLI) and extensions on top of AWS Cloud Formation to simplify the development of serverless applications.
In this video, James Eastham walks you through how to initialise, build, deploy and develop against your first serverless Java application. He looks at how SAM compiles and deploys your code and also an easy way to speed up the software development life cycle.
Great video featuring two of my most favourite people, Julian Wood and John Jackson take a look at how to effectively run Amazon Managed Workflows for Apache Airflow (Amazon MWAA) at scale. You hear about options available to scale workloads, explore different techniques to optimise performance when running at scale, with a demo running thousands of DAGs at scale.
