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 […]

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 […]

This post was written by Nelson Assis, Zoltan Bozoky, Soyean Kim, and Victor Leung. The COVID-19 pandemic highlighted areas needing improvement in the Canadian healthcare and life sciences ecosystem. For example, as ICU beds filled with COVID-19 patients, healthcare professionals working on infection prevention and control did not have as much availability for processing patient […]

In April this year, we introduced OpenSearch, a community-driven, open source search and analytics suite derived from open source Elasticsearch 7.10.2 and Kibana 7.10.2. The project consists of a search engine (OpenSearch), a visualization and user interface (OpenSearch Dashboards), and the advanced features from Open Distro for Elasticsearch (our previous distribution of Elasticsearch) such as […]

AWS Distro for OpenTelemetry (ADOT) 0.11.0 is now available. Release highlights include support for Amazon Elastic Kubernetes Service (Amazon EKS) metrics. Amazon EKS metrics can be monitored in Amazon CloudWatch Container Insights and include CPU usage, memory, disk and network status, in addition to other infrastructure metrics. ADOT 0.11.0 also supports Prometheus metrics collected from […]

This post was written by Steve Borrelli, Rob Clark, Manabu McCloskey, Vikrant Kahlir, and Nima Kaviani. In a previous blog post, we discussed how GitOps, declarative definition of infrastructure and application resources, and using technologies such as AWS Controllers for Kubernetes (ACK) and Crossplane have enabled DevOps engineers to reduce complexity and improve visibility into […]
