Feedback

Please let me know how we can improve this newsletter 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 30 seconds to complete. Thank you so much!

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: Lars Jacobsson, David Boyne, Agus Marchi, Hardik Singh Behl, Allan Chua, Diego Gomes, Bill Pereira, Lee Hung Nguyen, JΓ©rΓ©mie Rondon, Kyle Lee, Mark Sailes, Heather Jeong, Jimmy Kang, Jimmy Tam, Aidan Steele, Shaun Scovil, and Samrose Ahmed.

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

workload-discovery-on-aws

workload-discovery-on-aws is a solution to visualize AWS Cloud workloads. With it you can build, customize, and share architecture diagrams of your workloads based on live data from AWS. The solution maintains an inventory of the AWS resources across your accounts and regions, mapping their relationships and displaying them in the user interface.

You can view more details by checking out the implementation guide over at, Workload Discovery on AWS

aws-resource-explorer-cli

aws-resource-explorer-cli is the latest project from AWS Community Builder Lars Jacobsson, and provide a cli for the recently announced Resource Explorer feature (read more about that in the blog post, Introducing AWS Resource Explorer – Quickly Find Resources in Your AWS Account from my colleague Danilo Poccia). The cli tool allows you to quickly find what you are looking for in the console before launching the web browser in the right place.

cdk-schema-watcher

cdk-schema-watcher Serverless Developer Advocate and all round open source good guy David Boyne has been hard at the open source forge again, this time with his latest creation, SchemaWatcher. SchemaWatcher is a CDK construct that can help you scale your event-driven architecture by allowing event consumers to subscribe to schema changes. SchemaWatcher was designed to help developers manage their event-driven architecture. Notifying consumers of any changes to event structures can help catch issues before you see them in production. In David's words:

Over time our Event Driven Architectures (EDA) grow and it can become difficult to understand the impact of changes to downstream consumers. Producers can easily change their event schemas without consumers being aware. SchemaWatcher was built to help you setup notifications for your downstream consumers when using EventBridge. Never let a breaking schema scare you again!

David's projects have one common trait - amazing documentation, and SchemaWatcher is no different. You can view the documentation at cdk-schema-watcher.vercel.app

aws-serverless-scheduler

aws-serverless-scheduler this repo from Agus Marchi is a fork of a similar project (aws-scheduler) but with a narrower focus, scheduling webhook-related tasks. How does it work? The docs have you covered, but to schedule a trigger you have to publish an event (format spec is provided in the docs). There are some limitations to check out, but if you are looking for a way to schedule large amounts of point in time events with a great time precision, and they are webhook related, then this is a project for you my friend.

cloudenv

cloudenv is an open source proof of concept from Aidan Steele that allows your AWS Lambda functions to be configured to use secrets stored in AWS Parameter Store and AWS Secrets Manager in the same way that AWS ECS task definitions can be. Aidan has put together a detailed blog post, Configuration in the cloud, that goes into more details. Take a look and get back to Aidan with your feedback.

nitrogen

nitrogen is my vote for coolest project name this week, and is an open source tool for deploying web services to AWS Nitro Enclaves. Given a dockerfile and an ssh key, Nitrogen will spin up an EC2, configure the network, and build and deploy your web service. You get back a hostname that’s ready to go. Nitrogen is fully open source and it comes with pre-built scripts for deploying popular services like Nginx, Redis, and MongoDB. This sounds pretty amazing to me, so this is going straight to the top of the todo list.

Make sure you check out the documentation, which really does help explain and show how you might use enclave technology, as well as seeing the other demos from Cape Privacy, which you can find here demos.capeprivacy.com

sovereign-keys

sovereign-keys Sovereignty has become a concern for some companies as they plan and move to Cloud computing. This project is designed around the hypothesis that your Cloud provider is not actively seeking to steal your data for its own gain, but rather that it can be forced by the law to surrender your data to a (foreign) government. Sovereign Keys gives you additional data protection guarantees and also provides an excuse that Cloud providers can use to argue they cannot comply with legally issued requests to access your data (e.g. requests issued under the CLOUD Act).

architecture overview of the sovereign-keys

There is a lot of stuff to go through in this project, and the examples and documentation is very detailed. JΓ©rΓ©mie Rondon has also put together this video to walk you through it too. Grab your favourite beverage and strap yourself in, this is a great deep dive session into how this works.

Demos, Samples, Solutions and Workshops

soap-to-serverless-modern-infrastructure-for-mature-apis

soap-to-serverless-modern-infrastructure-for-mature-apis this project provides a SOAP Service written in NodeJS that communicates with API Gateway which transforms the information payload using VTL to Lambda. Lambda responds back to API Gateway to maintain backward to SOAP and in JSON to REST calls. The repo provides a sample use case as to why this project might be helpful. A company has a legacy application communicating between layers using SOAP Services. The team that is in charge of the business logic wants to start migrating part of the code to Serverless but have backward compatibility with the front-end layer. So communication between the front-end and backend has to remain in SOAP contract but with business logic in serverless solution. This example show how to do that.

react_aws_static_hosting

react_aws_static_hosting is a demo repository from Allan Chua for hosting static React websites using AWS, CloudFront, WAF & CloudFront Origin Policies.

image-content-moderation

image-content-moderation is a proof of concept from Hardik Singh Behl, that exposes a single REST API endpoint to set/update user's current profile picture. Amazon Rekognition has been integrated in the service layer to detect any inappropriate, suggestive, unwanted or offensive content in the image being uploaded, If any ModerationLabels are detected the API returns HttpStatus.NOT_ACCEPTABLE. On successful content moderation evaluation, HttpStatus.OK is returned by the endpoint. Check the README for a short video of how this works.

sagemaker-datawrangler

sagemaker-datawrangler this repo contains example flows that demonstrate how to aggregate and prepare data for Machine Learning using Amazon SageMaker Data Wrangler. Isha Dua has put together a blog post, Use Github Samples with Amazon SageMaker Data Wrangler to help get you started.

AWS and Community blog posts

Terraform CDK

Shaun Scovil has put together this post, Using Terraform CDK with LocalStack (Python) (with a nice illustration courtesy of Midjourney) that is intended for anyone who is trying to get Terraform CDK to work with LocalStack. For those who may be unfamiliar, LocalStack is an open source tool that enables you to run cloud service emulator in a single container on your laptop or in your CI environment. Very nice idea and post, so well worth five minutes of your time this week. [hands on]

Apache Iceberg

Matano is an open source security lake platform for AWS, which I have featured in previous editions of this newsletter. Samrose Ahmed peeks under the covers as he writes, Automated Iceberg table maintenance and how table maintenance works and how they are able to run completely serverless Iceberg table maintenance on AWS.

Micronaut

In a collaboration between Mark Sailes, Heather Jeong, Jimmy Kang, and Jimmy Tam, they have got together to write Improving Developer Productivity at Disney with Serverless and Open Source where they share how they are combining serverless and open source technologies to improve their ability to deliver business value safely and reliably.

Apache Flink

Apache Flink is an open-source framework and engine for stateful processing of data streams. It’s highly available and scalable, delivering high throughput and low latency for the most demanding stream-processing applications. In Learn more about Apache Flink and Amazon Kinesis Data Analytics with three new videos, there are three new videos for you to learn more about Apache Flink and Kinesis Data Analytics, including open-source contributions to Apache Flink, our learnings from running thousands of Flink jobs on a managed service, and how we use Kinesis Data Analytics and Apache Flink to enable machine learning (ML) in Alexa.

AWS Amplify

This week we had a number of great posts for Web and Mobile developers.

In this first of a two part post, Building Offline first applications with AWS Amplify DataStore – Part 1, Diego Gomes shows how AWS Amplify DataStore addresses some of the challenges of building Offline first applications. [hands on]

architecture overview of amplify datastore

Following that we had Kyle Lee write, Getting Started with AWS Amplify on macOS who shows you how to use Amplify Auth sign in with web UI to authenticate a user across both macOS and iOS. Get into XCode and off you go...! [hands on]

Quick updates

Redis

Amazon ElastiCache for Redis now supports Redis 7. This release brings several new features to Amazon ElastiCache for Redis:

  • Redis Functions: ElastiCache for Redis 7 adds support for Redis Functions, and provides a managed experience enabling developers to execute LUA scripts with application logic stored on the ElastiCache cluster, without requiring clients to re-send the scripts to the server with every connection.
  • ACL improvements: ElastiCache for Redis 7 adds support for the next version of Redis Access Control Lists (ACLs). With ElastiCache for Redis 7, clients can now specify multiple sets of permissions on specific keys or keyspaces in Redis.
  • Sharded Pub/Sub: Amazon ElastiCache for Redis 7 now gives you the ability to run Redis’ Pub/Sub functionality in a sharded way when running ElastiCache in Cluster Mode Enabled (CME). Redis’ Pub/Sub capabilities enable publishers to issue messages to any number of subscribers on a channel. With Amazon ElastiCache for Redis 7, channels are bound to a shard in the ElastiCache cluster, eliminating the need to propagate channel information across shards resulting in improved scalability.

Amazon EMR

Announced earlier this week was the general availability of job templates in Amazon EMR on EKS. Job templates allow you to create and store templates to configure Spark applications parameters. This helps you ensure consistent settings across applications by reusing and enforcing configuration overrides in data pipelines.

EMR on EKS applies default Spark settings to optimise an application’s performance when customers use the StartJobRun API to run Spark-based applications and data pipelines. With job templates, data engineers can now define reusable templates to apply additional customisations, configuring executor and driver compute capacity, setting security and governance properties such as IAM roles, and customised docker image to use across multiple applications and data pipelines. Additionally, customers can also enforce specific configuration values, preventing overrides when calling the StartJobRun API using the template. Job templates can be optionally encrypted with customer-managed master keys stored in AWS Key Management Service.

AWS Copilot

AWS announced the general availability of AWS Copilot version 1.23 with support for AWS App Runner private services. App Runner makes it easier for developers to quickly deploy containerised web applications and APIs to the cloud, at scale, and without having to manage infrastructure. By default, App Runner services are accessible publicly over the internet. Now, with private services you can restrict network access to your internal websites, APIs, and applications to originate from within your Amazon VPC.

With AWS Copilot, you can quickly get started and deploy to Amazon ECS or AWS App Runner with a single command and a Dockerfile. Copilot provides a developer-focused interface and workflows, where users can focus on application architecture by choosing common application and services patterns. Copilot provisions and keeps up to date the necessary AWS infrastructure in your account, using the best-practices and infrastructure-as-code artefacts. Now, you have the option of toggling the request-driven Copilot services, powered by App Runner, to be private. Simply specify http.private: true in the Copilot service manifest and run copilot deploy command. Copilot will take care of configuring AWS App Runner services to accept traffic only from within Amazon VPC provisioned for your Copilot environment.

Videos of the week

Ansible

Bill Pereira shows you how you can use Ansible to transfer data. between #zOS and #AWS, using the #ibm_zos_core modules to backup and restore, and the #AMAZON #AWS modules to put and get data from the #S3 buckets.

O3DE

In 2022, there are so many 3D engines that exist that you can barely keep a count on it. With multiple experiences, comes complex design problems to solve on a day to day basis. This is where design systems come in. There's no need to reinvent the wheel; when we can all just align on the most expected and common design patterns for users to experience. The BlueJay Design System is the official design system for Open 3D Engine. Lee Hung Nguyen is your speaker as he outlines what is involved in planning and building the best open source design system for the 3D engine.

Dagger

Dagger is an open source programmable CI/CD engine that runs your pipelines in containers. You can follow along with the Containers on the Couch crew via Twitch or LinkedIn as they introduce this project and then walk you through a demo.
