Latest from open source projects


scikit-learn-lambda is an open source project from Model Zoo that provides a toolkit for deploying scikit-learn models for realtime inference on AWS Lambda. This project provides a few things; first, it provides a handler for serving scikit-learn predictions via AWS Lambda, designed for use with API Gateway; second, it provides supporting Lambda layers that include the necessary supporting libraries; and thirdly, examples of how to get this up and running. Checkout the documentation as it also includes some cost benchmarks.


mock-aws-java-sdk - local testing can be easy with this open source project from Andrew O'Hara, which provides a library that lets you mock AWS out of your tests, allowing you to achieve for better coverage with far less hassle. Works with Java 8, clear documentation and samples provided to get you up and mocking. Not all AWS services are supported yet, so if the one you need is missing, why not add it yourself and grow the project.


mir_robot - project from Junchuan Zhang that shows off the MiR robot in the AWS warehouse gazebo environment. The project provides plenty of guidance on how to set this up, and whether you have a MiR robot or not, you can still get this up and running and test it out - one of the great advantages of ROS is that it allows you to experiment with robots you do not quite have yet!



c3 this open source project, C3: Compliant Cloud Components from SSH Communications Security Oyj
is a library provides configuration to AWS CDK components which is compliant with CIS, GDPR and other security standards. The library acts as an overlay for existing AWS CDK components. It aims to minimize effort required to enable compliancy with privacy and security best practices.


SyntheticSun an open source project from Jonathan Rau, is a defense-in-depth security automation and monitoring framework which utilizes threat intelligence, machine learning, managed AWS security services and, serverless technologies to continuously prevent, detect and respond to threats. This is now GA, so if you haven't already done so get over to the repository and check it out asap.

Unbundling Data Science Workflows with Metaflow and AWS Step Functions, in the collaboration between David Berg, Ravi Kiran Chirravuri, Romain Cledat, Jason Ge, Savin Goyal, Ferras Hamad and Ville Tuulos, they announce new capabilities with the Metaflow tool that Netflix open sourced late last year. Metaflow is a framework that attempts to abstract the complexities of data science and engineering tasks using a layered approach. As the posts states at the start:

The idea of abstraction layers is a fundamental way to manage complexity in computing: Atoms make transistors, transistors make functional units in CPUs, CPUs implement instruction sets that are targeted by compilers for higher-level languages. A key benefit of these layers is that they can be developed independently by separate groups of people, as they are coupled together only through a well-scoped interface. The layers can have independent life cycles that enable higher layers of the stack to maintain a semblance of stability without hindering innovation at the layers below.

This post dives deep into the scheduling layer and specifically how they are integrating with AWS Step Functions. You can check the Netflix Tech blog for earlier posts on Metaflow as well if you want to start with a primer, then check out this post - Open-Sourcing Metaflow, a Human-Centric Framework for Data Science

Case Study


In this customer case study from Bhinneka, Bhinneka Cuts Time-to-Market in Half with AWS they share how they "reduced our costs by 30 percent with AWS, while gaining a broader set of open-source cloud applications and uptimes of 99.98 percent." according to CTO Lodewijk Tanamal.

Launched 25 years ago, Bhinneka is an offline retailer in Indonesia that has embraced e-commerce. The company now runs business-to-consumer (b2c), business-to-business (b2b), and business-to-government (b2g) websites, selling office supplies to b2b and b2g customers and a wide range of items including clothing, tools and computers to its b2c audience.

To drive innovation, it wanted to switch from proprietary to open-source software to cut costs and free up resources for artificial intelligence (AI) and machine-learning (ML) projects. Lodewijk added, “We’ve reduced our costs by 30 percent by moving our Windows workloads to Linux on AWS, while gaining a broader set of Linux cloud applications and uptimes of 99.98 percent.”

AWS ParallelCluster 2.8.0

AWS ParallelCluster is a fully supported and maintained open source cluster management tool that makes it easy for scientists, researchers, and IT administrators to deploy and manage High Performance Computing (HPC) clusters in the AWS cloud. HPC clusters are collections of tightly coupled compute, storage, and networking resources that enable customers to run large scale scientific and engineering workloads. Significant feature enhancements to this latest release of ParallelCluster include:

  • Support for ARM-based instances: AWS has recently released both the M6g and the C6g instances that use the next-generation ARM-based chip designed by AWS (and Annapurna Labs, an Amazon company), utilizing 64-bit Arm Neoverse N1 cores. These instances give customers another way to optimize their price performance (up to 40% cost-performance ratio improvement relative to M5 instances) on AWS when running their HPC workloads in AWS.
  • Enhanced pcluster update functionality: The pcluster update command allows customers to modify attributes of a running ParallelCluster cluster such as the instance type of compute nodes. With the latest version of ParallelCluster we have provided an improved interface so that customers can stage and inspect the changes to be applied by an update action before execution, as well as review instructions for further actions required to perform the update safely.
  • Support for automatic backups with FSx for Lustre: You can now create point-in-time backup copy of your FSx for Lustre file system, use backups as the source for your Lustre file system, and specify a schedule for creating these file system backups. You can find more information on this backup feature here as well as information on how to configure it in ParallelCluster here.
