AWS Open Source Blog

In this blog post, intern engineers Karen Xu and Kelvin Lo describe their experience working in the popular open source project, OpenTelemetry. They describe how they added security scanning workflows to the project, including how it supports a major milestone in readying the software for production use. In any important and widely adopted open source […]

Today we announce the alpha release of DenseClus, an open source package for clustering high-dimensional, mixed-type data. DenseClus uses the uniform manifold approximation and projection (UMAP) and hierarchical density based clustering (HDBSCAN) algorithms to arrive at a clustering solution for both categorical and numerical data. With DenseClus, you provide a dataframe, and it will then […]

With Amazon Web Services (AWS) customers adopting Amazon Managed Service for Prometheus (AMP) on Amazon Elastic Kubernetes Service (Amazon EKS), we often see requests for information regarding best practices to follow when moving self-managed Prometheus on Amazon EKS to AMP. In this article, we’ll examine those best practices, with a focus on the five pillars […]

The OpenSearch project is a long-term investment in a secure, high-quality, Apache-2.0 licensed search and analytics suite with a rich roadmap of innovative functionality. OpenSearch aims to provide wire compatibility with open source distributions of Elasticsearch 7.10.2, the software from which it was derived. This makes it easy for developers to migrate their applications to […]

Apache Airflow‘s active open source community, familiar Python development as directed acyclic graph (DAG) workflows, and extensive library of pre-built integrations have helped it become a leading tool for data scientists and engineers for creating data pipelines. Amazon Managed Workflows for Apache Airflow (Amazon MWAA) is a fully managed service that makes running open source […]

Core WCF is a port of Windows Communication Framework (WCF) to .NET Core. Used to build service-oriented applications based on the .NET Framework, WCF enabled applications to asynchronously send data, packaged as messages, between service endpoints. WCF is a popular framework supporting many service-based use cases, including processing business transactions, reporting, monitoring, exposing workflows (implemented […]

Musician activities, such as choir and band rehearsals—or jamming out—were largely grounded by the Covid-19 pandemic lockdowns. Many of these groups needed alternatives, and they often resorted to videoconferencing tools, such as Amazon Chime or open source tools, such as Jitsi. Most of these solutions are optimized for conversation, however, not for music, so they […]

One of the best things about open source is its community. It’s the community that helps to popularize a project. It’s the community that helps to build the project through code, documentation, and other contributions. It’s the community that sometimes turns into paying customers, too. But it’s also the community that may compete with you. […]

The benefits of the serverless architecture are not reserved to newly written applications. Legacy code can be combined with leading-edge technologies by deploying them in a cloud platform. This will ensure reuse of the massive existing legacy assets and further extend their life, thus using them in new ways. Serverless COBOL: Rejuvenating legacy code with […]

In this post, we explain how using open source software, GnuCOBOL, combined with AWS Lambda functions, can extend the life of legacy code into a serverless context. We also examine additional benefits of open source software when legacy features are deployed in such a modern environment. The COBOL code described in this post—CI/CD scripts—are available […]
