AWS open source news and updates #57

February 22nd, 2021 - Instalment #57

Newsletter #57.

This week we have another great selection of content to share with you. Starting off with a look at open source at AWS, which is a must read this week, we meander through a look at a write up of the open source technology stack that supported Fossdem a few weeks ago. Then it is off to the usual round up of latest open source projects, blog posts from the community and AWS as well as a look at some quick updates, videos and more. We also have a job working AWS SDK team, so if you love Rust why not take a look.

Open source at AWS

In this post in The New Stack, The Open Source Strategy of Amazon Web Services, Richard MacManus shares some thoughts on how AWS think about and contribute to open source. A nice piece with some great data points.


A few weeks ago Fossdem ran virtually, and there were a number of great sessions over the weekend. It was important to get the technology right given the numbers attending these remotely, and certainly from the sessions I attended, it was a great success. In this blog post, How we hosted FOSDEM 2021 on Matrix Matthew Hodgson shares how Matrix, an open source project which defines an open standard protocol for decentralised communication, was used to deliver a virtual Fossdem. Some really great data points, a look at the architecture and open source tools used, this is a fantastic write up which I urge you to check out to see how you can use open source tools to potentially run your own virtual events.

A couple of posts this week covering Dask, an open source library for parallel computing written in Python. Dask is a library composed of two parts. The first is a task scheduling component for building dependency graphs and scheduling tasks, and second, it includes the distributed data structures with APIs similar to Pandas Dataframes or NumPy arrays. Dask can scale from a single node and scale to thousand node clusters.

In the first blog post, Computer Vision at Scale with Dask and PyTorch on Amazon EC2 Spot Instances Hugo Shi (Co-Founder and CTO at Saturn), Stephanie Kirmer, Sr. Data Scientist at Saturn as well as Kinnar Sen and Dan Kelly from AWS explain how Saturn Cloud makes it easy for customers to satisfy the performance requirements of many data science and ML workloads while optimising price performance. The post walks through how to provision a cluster of On-Demand and Spot Instances to meet a set of required performance specifications, and compares this against other approaches.


Next up we have Ram Vittal and Sireesha Muppala, Machine learning on distributed Dask using Amazon SageMaker and AWS Fargate, which is a really nice follow on post where they demonstrate how to solve common ML problems such as exploratory data analysis on large datasets, preprocessing (such as one-hot encoding), and linear regression modelling using Fargate as the backend. They show you how to connect to a distributed Dask Fargate cluster from a SageMaker notebook, scale out Dask workers, and perform exploratory data analysis work using a sample data set along the way.



Training, debugging and running time series forecasting models with the GluonTS toolkit on Amazon SageMaker Prem Ranga, Jana Gnanachandran, Mona Mona, and Nathalie Rauschmayr show you how to set up and run time series forecasting models at scale using Gluon Time Series (GluonTS) on Amazon SageMaker.

Flutter support in AWS Amplify is now generally available (GA). Amplify is a set of tools and services that help frontend web and mobile developers build secure, scalable, full-stack applications. Flutter is an open-source UI software development kit created by Google for developing applications for Android and iOS from a single codebase. Amplify Flutter brings together Amplify and Flutter. It is designed for developers who have invested in the Flutter ecosystem and now want to take advantage of the power of AWS. You can use the Amplify Flutter libraries with Amplify-created backends, as well as existing AWS backends.

Compared to the initial Developer Preview, the GA release adds Data, API, and Auth capabilities. Amplify DataStore, now supported in Amplify Flutter, provides a local programming model that makes working with distributed, cross-user data as simple as working with local-only data. No additional code is required for offline and online scenarios. Amplify Flutter’s new API capabilities provide clients for making signed HTTP requests to both GraphQL and REST endpoints. Finally, today’s GA release adds support for authenticating app users using Hosted UI. Hosted UI is a customizable OAuth 2.0 flow that allows developers to launch a login screen without embedding the SDK for Cognito or a social provider—such as Facebook, Google, and Amazon—in your application.


Amazon Elasticsearch Service adds Trace Analytics, a new feature for distributed tracing that enables developers and IT operators to find and fix performance problems in distributed applications, leading to faster problem resolution times.

Trace Analytics enables developers and IT Ops to troubleshoot performance and availability issues in their distributed applications, giving them end-to-end insights not possible with traditional methods of collecting logs and metrics from each component and service individually. By adding trace data to the existing log analytics capabilities of Amazon Elasticsearch Service, customers can use the same service to both isolate the source of performance problems and diagnose their root cause. Trace Analytics supports OpenTelemetry, a Cloud Native Computing Foundation (CNCF) project which provides a single set of APIs, libraries, agents, and collector services to capture distributed traces and metrics, enabling customers to leverage Trace Analytics without having to re-instrument they applications.

Trace Analytics today supports collection of trace data from application libraries and SDK’s that are compatible with the open source OpenTelemetry Collector, including OpenTelemetry SDKs, X-Ray SDKs, Jaeger and Zipkin SDKs. Trace Analytics also integrates with AWS Distro for OpenTelemetry, which is a distribution of OpenTelemetry APIs, SDKs, and agents/collectors. It is a performant and secure distribution of OpenTelemetry supported by AWS. Customers can use AWS Distro for OpenTelemetry to collect traces and metrics for multiple monitoring solutions, including Amazon Elasticsearch Service and AWS X-Ray for trace data, and Amazon CloudWatch for metrics. For more information on configuring and using Trace Analytics, please see documentation.
