AWS Open Source Blog

This article is a guest post from Jaoquin Menchaca, an SRE at Dgraph. Dgraph is an open source, distributed graph database, built for production environments, and written entirely in Go. Dgraph is fast, transactional, sharded, and distributed (joins, filters, sorts), consistently replicated with Raft, and provides fault tolerance with synchronous replication and horizontal scalability. The […]

In this post, three AWS interns—Brandon Kimberly, Ankit Bhargava, and Hudson Humphries—describe their first engineering contributions to the popular open source observability project OpenTelemetry. Recently we made contributions to OpenTelemetry that included the metrics collection and processing functionality for the C++ library. These metrics are collected from instrumented applications and infrastructure. They allow users to […]

As our customers increasingly adopt containers to run their workloads, we saw a need for a Linux distribution designed from the ground up to run containers with a focus on security, operations, and manageability at scale. Customers needed an operating system that would give them the ability to manage thousands of hosts running containers with […]

In September 2019, we published a blog post, Building a Serverless FHIR Interface on AWS, which explained why customers might want to use FHIR (Fast Healthcare interoperability Resources) as a healthcare interface, and why serverless technology is a cost-efficient and flexible approach to these interfaces. The post explained the basic concepts underpinning FHIR, and how […]

This post is contributed by Xiaoyan Zhang, a Data Scientist from TalkingData. TalkingData is a data intelligence service provider that offers data products and services to provide businesses insights on consumer behavior, preferences, and trends. One of TalkingData’s core services is leveraging machine learning and deep learning models to predict consumer behaviors (e.g., likelihood of […]

A common request from AWS ParallelCluster users is to have the ability to deploy multiple POSIX user accounts. The wiki on the project GitHub page documents a simple mechanism for achieving this, and a previous blog post, “AWS ParallelCluster with AWS Directory Services Authentication,” documents how to integrate AWS ParallelCluster with AWS Directory Service. However, […]

Large-scale distributed software systems are composed of several individual sub-systems—such as CDNs, load balancers, and databases—and their interactions. These interactions sometimes have unpredictable outcomes caused by unforeseen turbulent events (for example, a network failure). These events can lead to system-wide failures. Chaos engineering is the discipline of experimenting on a distributed system to build confidence […]

This post was contributed by AWS Serverless Hero Ben Ellerby. One of the most exciting things about serverless is the acceleration it can provide to teams. No longer do you have to invest time in the undifferentiated, heavy lifting of managing the infrastructure of our applications. Instead you can spend time writing code that creates […]

AWS provides a collection of tools and services to give customers the ability to manage the resources within their AWS accounts. In this article I will briefly explore some of these tools and services, as well as an open source project that can be used to integrate AWS cost-management services and features directly into Red […]

Madelyn Olson may not be the most well-known of open source developers, but chances are you’ve benefited from her work. Olson is a new maintainer for and a longtime contributor to Redis, one of the world’s most popular databases and regularly touted by developers as the most loved. You’ve used Redis when on Twitter, GitHub, […]
