This week we have a couple of OpenShift posts.

AWS PrivateLink allows customers to deploy workloads without the need to expose systems to the internet, and in this post, Red Hat OpenShift Service on AWS: private clusters with AWS PrivateLink, Ryan Niksch takes a look at some architectures that allow you to do this with your OpenShift clusters and applications.


Following that we have How to Use Webhooks to Automate Red Hat OpenShift App Rebuilds from AWS CodeCommit from Mehdi Salehi from AWS and Boris Jelic from IBM, where they show you how you can automate their OpenShift builds when a change is pushed into their code repositories on AWS CodeCommit. [hands on]



Nathan Arnold and Praseeda Sathaye take a look at how to secure communications between micro services running across different Amazon EKS clusters in different AWS account, in the post Enabling mTLS in AWS App Mesh using SPIFFE/SPIRE in a multi-account Amazon EKS environment. This is the third post of the series, so if you missed the others, you can find them lined here. [hands on]


Porting Assistant for .NET

Porting Assistant for .NET is an open source analysis tool that reduces the manual effort and guesswork involved in porting .NET Framework applications to .NET Core or .NET 5. Prasad Rao and Pavankumar Kasani have come together to write Modernizing legacy WCF applications to CoreWCF using Porting Assistant for .NET which walks you through the process of porting legacy WCF application to CoreWCF using Porting Assistant for .NET as a standalone tool. [hands on]



Elamaran Shanmugam and Munish Dabra walk you through how to set up Amazon Managed Grafana to retrieve metrics from Amazon Managed Service for Prometheus and Amazon CloudWatch from different AWS accounts running container workloads using customer managed IAM roles, in the blog post Setting up Amazon Managed Grafana cross-account data source using customer managed IAM roles [hands on]



Last week I had the chance to speak to Romaric Philogène about his blog post, How to Build a Cloud Version of Your Open Source Software: Part 1 which is the first in a series of posts where he will share with you one approach in creating a multi-tenant versions of some popular open source projects, deployed via Qovery onto AWS. Make sure you do not miss this series.

Apache Cassandra

Arturo Hinojosa takes a look at a widely used feature of Apache Cassandra, Time to Live (TTL). This helps developers manage storage costs and simplify application logic, and the post explains how the serverless nature of Amazon Keyspaces (for Apache Cassandra) address' the challenges of using TTL in Cassandra workloads by offering a fully managed version of TTL that doesn’t impact application performance or introduce availability risks for applications. Read more in Announcing Amazon Keyspaces Time to Live (TTL) general availability

Amazon Kinesis Data Streams

Education technology (EdTech) company GoGuardian announces the availability of a Go Client library for Amazon Kinesis Data Streams via open source, and Kevin Nguyen, Matt Dalida, and Sohil Gogri share more details in the blog post GoGuardian releases Go code library via open source for Amazon Kinesis Data Streams

Location Services

In this blog post Simulated location data with Amazon Location Service from Aaron Sempf and Florian Seidel, you will find out how you use an open-source project and open-source data to generate simulated trips, as well as how to play those trips back to the Amazon Location Service Tracker. [hands on]


AWS Greengrass

AWS IoT Greengrass 2.0 is an open-source edge runtime, and in this post How Boston Dynamics and AWS use mobility and computer vision for dynamic sensing, Brad Bonn from Boston Dynamics and Jon Slominski from AWS share how AWS IoT Greengrass enables Spot (Boston Dynamics' quadruped robot) to send data back to the cloud with flexibility for varied use-cases.



CARLA is an open-source simulator for autonomous driving research. It has been developed from the ground up to support development, training, and validation of autonomous driving systems. In the post, Run any high-fidelity simulation in AWS RoboMaker with GPU and container support Matt Hansen takes a look at how you can now run a CARLA autonomous driving simulator in AWS RoboMaker, thanks to the new features that make it possible to use any robot simulator and robot software to run high fidelity GPU based simulation jobs.


Quick updates

Porting Assistant for .NET

Porting Assistant for .NET is an open source analysis tool that reduces the manual effort and guesswork involved in porting .NET Framework applications to .NET Core or .NET 5, helping customers move to Linux faster. It identifies incompatibilities with .NET Core or .NET 5, generates an assessment report with known replacement suggestions, and assists with porting.

Porting Assistant for .NET now supports assessment and porting of Windows Communication Foundation (WCF), Open Web Interface for .NET (OWIN), and ASP.NET System.Web.Mvc namespaces to .NET Core 3.1 or .NET 5. Following the GA release of Core WCF project in February 2021, Porting Assistant can now assess and provide recommendations to port WCF applications to Core WCF. It also supports assessment and porting of OWIN and System.Web.Mvc namespace configurations to .NET Core 3.1 or .NET 5. Developers can use the existing Porting Assistant for .NET tool or Porting Assistant for .NET Visual Studio IDE extension to get started.

Amazon Corretto

Amazon Corretto 11.0.13 and 8.312 are now available for download. Amazon Corretto 17 updates will be available shortly after the release is tagged in the OpenJDK 17 repository. Amazon Corretto is a no-cost, multi-platform, production-ready distribution of OpenJDK.

AWS Amplify

AWS Amplify for JavaScript now supports pause, resume and cancel actions on file uploads to Simple Storage Service (Amazon S3) via the Amplify Storage category. Amplify provides a set of use-case oriented UI components, libraries and command-line tools to make it easy for frontend web and mobile developer to build AWS cloud backends for their apps. With this release, developers can create experiences where end-users can reliably upload very large files, including raw video and large productivity documents. Being able to resume uploads is particularly useful for handling scenarios where a user experiences network interruption during an upload.

The Amplify JS library will now automatically segment large files into 5Mb chunks, and upload them using the Amazon S3 Multipart upload process. This method allows chunks to be uploaded in any order, and individual chunks can be re-transmitted if their upload fails or times out. Developers are able to provide callback logic to control how and when re-transmits should be attempted.


Amazon RDS Proxy now supports Amazon RDS for MySQL major version 8.0. MySQL 8.0 is the latest Community Edition major version, and offers better performance, reliability, security, and manageability.

We have updated Amazon Relational Database Service (Amazon RDS) for MySQL on Outposts to support MySQL minor versions 8.0.23, and 8.0.25. We recommend that customers upgrade to the latest minor versions to fix known security vulnerabilities in prior versions of MySQL, and to benefit from the numerous bug fixes, performance improvements, and new functionality added by the MySQL community.


FreeRTOS adds symmetric multiprocessing (SMP) support in the kernel, enabling developers designing FreeRTOS-based applications to utilize the SMP capabilities of multi-core microcontrollers. Multi-core microcontrollers, in which two or more identical processor cores share the same memory, allow the operating system to distribute tasks between cores to balance processor load as desired by the application. This allows applications to optimize the resource utilization of multi-core microcontrollers.

The FreeRTOS SMP kernel has a consistent set of configuration options, APIs and behaviors for systems with multiple compute cores, so developers will be able to transition between multi-core and single-core systems with minimal effort. There are reference implementations on the xcore platform from XMOS and Raspberry Pi Pico, but for more details on the FreeRTOS SMP kernel and how to port to other platforms, see Porting to FreeRTOS SMP Kernel.
