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 […]

AWS Cloud Development Kit (AWS CDK) is an open source software development framework used to define cloud application resources using familiar programming languages. AWS CDK can build container images locally, deploying them to Amazon Elastic Container Registry (Amazon ECR), and configure them to run as Lambda functions. AWS CDK accelerates onboarding to AWS because there […]

The AWS IoT Device SDK for Embedded C (C-SDK) is composed of a set of MIT-licensed libraries that demonstrate simplified, lightweight, and secure connectivity to AWS IoT Core and device-side operations to AWS IoT services. The AWS IoT C-SDK can work on a variety of operating systems, such as Linux, macOS, and Windows, or a […]

In February, Josh Aas from Internet Security Research Group, Daniel Stenberg from curl, and I (from hyper and Amazon Web Services) hosted a joint webinar to discuss memory safety and the internet, and how using hyper in curl can help make the internet safer. Because curl is open source and permissively licensed, it is found […]

Grafana Loki was introduced in 2018 as a lightweight and cost-effective log aggregation system inspired by Prometheus. Grafana, often with Prometheus, is a popular open source platform for monitoring and observability that can be used to query, visualize, and create alerts on a number of metric and data sources. With the increase in maturity of […]
