Latest open source projects



botocove this project from Dave Connell provides a simple decorator for functions to run them against all AWS accounts in an organisation. You can run a function against a selection of AWS accounts, Organisational Units (OUs) or all AWS accounts in an organisation, concurrently with thread safety. Run in one or multiple regions.


functionless this new project from Sam Goodwin is a TypeScript plugin that transforms TypeScript code into Service-to-Service (aka. "functionless") integrations, such as AWS AppSync Resolvers and Velocity Templates, or (coming soon) Amazon States Language for AWS Step Functions. To find out more, with plenty of examples, dive into this repo.


replibyte current in alpha state, this new open source tool from the lovely folks at Qovery is a standalone application to replicate your cloud databases from one place to the other. The repo provides some background as to the motivation for the tool, and gives some example of how you can use this to synchronise PostgreSQL databases on AWS. One to watch.




eks-anywhere-packages EKS Anywhere curated packages is a framework to manage installation, configuration and maintenance of components that provide general operational capabilities for Kubernetes applications.


api-gateway-dynamic-publish this is a nice open sourced resources that uses AWS CDK and leverages an OpenAPI definition to define, document and create an Amazon API Gateway deployment. At deploy time, a CloudFormation Custom Resource is leveraged to dynamically substitute the Lambda integration function ARNs into the OpenAPI definition file as well as publishing the updated file to an S3 bucket for documentation viewing. This is a must check out project this week.




If you are looking for a way to be proactively notified of new security bulletins, then this project will be of interest. This CDK project deploys an AWS Lambda Function which is scheduled for every full hour. It checks the for new AWS Security Bulletins and sends out E-Mail notifications via Amazon SES.


Demos and Samples


aws-proton-tutorial Proton is a fully managed AWS service that helps engineering platform teams build developer portals to streamline the SDLC (software development lifecycle). Proton has two main goals: increase developers' productivity and agility while allowing organisations to maintain the right level of control and governance. This workshop/tutorial from Massimo Re Ferrè is for those of a curious nature that want to understand more.


eks-multi-environment-cdk-pipeline This project shows how AWS CDK can be used to provision and manage EKS cluster deployed in multiple environments. This project uses cdk-pipelines construct to create pipeline between the different Amazon EKS clusters that deployed in multiple environments. This project follows EKS Best practices guide, and deploy relevant add-ons like Cluster-Autoscaler, AWS Load Balancer Controller, and SSM Agent. It also deploys Weave Flux V2 for GitOps delivery. The reason that the Cluster add-ons are deployed using CDK and not using Flux, is because these add-ons require configurations both on the AWS and on the EKS/K8s (IAM roles and policies on AWS, and add-on deployment on K8s). All other application deployments will be deployed using Weave Flux V2.



serverless-java-frameworks-samples this repo provides a simple serverless application built in Java using popular frameworks, Micronaut, Quarkus, and Spring Boot



mediatailor-vod-upload this is a sample project and demo workflow that automates adding video on demand (VOD) sources to AWS MediaTailor Channel Assembly. To learn about AWS MediaTailor Channel Assembly, this workshop walks through defining sources, creating a channel and programs along with test source content.

Other posts worth checking out



Patterns for Ingesting SaaS Data into AWS Data Lakes is a new white paper that outlines different patterns using Amazon Web Services (AWS) services to ingest SaaS data into a data lake on AWS. It covers a number of different patterns, including how you can use Apache Spark, Apache Kakfa, and Amazon Athena Federated Queries.

Quick updates


The AWS JDBC Driver for MySQL is an open-source project that uses the General Public License v2 and is now generally available for use with your Amazon RDS or Amazon Aurora MySQL-compatible edition database clusters. This database driver minimises failover time by monitoring database cluster status and caching the cluster’s topology. The cache is then used to improve DNS name resolution speed if a node fails, reducing failover time from minutes to seconds. The MySQL JDBC driver is based on the MySQL Connector/J and supports MySQL deployments. It is drop-in compatible with the community MySQL driver and is installed with Maven, Gradle, or by .jar file. After installing the required file, your client requires simple changes to the connection string to use the new driver.

You can dive deeper in the blog post, Improve application availability with the AWS JDBC Driver for Amazon Aurora MySQL where Ryan Shevchik demonstrate how to use the AWS JDBC Driver for MySQL, and how your application can take advantage of the features of clustered MySQL databases.


Following the announcement of updates to the PostgreSQL database by the open source community, AWS has updated Amazon Aurora PostgreSQL-Compatible Edition to support PostgreSQL versions 13.5, 12.9, 11.14, and 10.19 in commercial and AWS GovCloud (US) Regions. These releases contain bug fixes and improvements by the PostgreSQL community.

Apache Cassandra

Amazon Keyspaces (for Apache Cassandra) is a fully managed Apache Cassandra compatible database service now helps you automate resource management by using the AWS SDK. Amazon Keyspaces helps you to run Apache Cassandra workloads more easily at scale by using a fully managed and serverless database service. Amazon Keyspaces works with your existing Cassandra drivers and Cassandra Query Language (CQL) API code. In addition, Amazon Keyspaces is integrated with AWS CloudFormation to help you automate provisioning and management of Amazon Keyspaces resources, such as keyspaces and tables. You also can use CloudFormation to manage encryption and point-in-time recovery (PITR) settings. Now, you also can create and manage Amazon Keyspaces resources by using the AWS SDK. AWS SDK support also allows you to use third-party automation tools that depend on the AWS SDK to manage your AWS resources.

Apache Kafka

You can now use AWS CloudFormation to manage Amazon Managed Streaming for Apache Kafka (MSK) cluster configurations and SASL/SCRAM secrets.


With the introduction of LZ4 data compression, you can now choose from two different compression options on Amazon FSx for OpenZFS file systems. LZ4 provides another highly popular performance-optimised compression option (in addition to Z-Standard) to help you optimise storage efficiency and performance based on the needs of your individual workloads.

Amazon FSx for OpenZFS provides fully managed, cost-effective, shared file storage powered by the popular OpenZFS file system. It offers powerful storage efficiency capabilities like data compression, enabling you to reduce storage consumption of the data in both your file system and your file system backups. Until today, FSx for OpenZFS file systems only supported Z-Standard compression, which is optimised for the highest levels of storage efficiency and is well-suited for a broad set of general purpose workloads. Now, you can also choose LZ4 data compression, which is optimised for delivering higher levels of write throughput for your performance-intensive write-heavy workloads.

Starting today, you can enable data compression and choose LZ4 as the compression algorithm using the AWS Console, AWS CLI, or FSx API.
