AWS attendee guide for Open Source at re:Invent 2021

AWS re:Invent happening November 29-December 3.

AWS re:Invent is a learning conference hosted by Amazon Web Services (AWS) for the global cloud computing community. Open source is a huge part of AWS and it is also a huge part of re:Invent. We can’t wait to show you the amazing open source work that is happening and to share the latest from AWS leaders and community. re:Invent is happening in person in Las Vegas (November 29-December 3) and virtually (November 29–December 10). If you are attending in person, please review the health and safety details on the re:Invent health measures page. If you are joining us virtually, please look at the virtual section.

This year, open source has a dedicated track, talking about the active work happening across AWS (and beyond)! Just as open source isn’t limited to one technology area, our track covers a wide range of focus areas and goes from intermediate (200) to advanced (300). In this post, we’ll give you a preview of what you should put on your personal schedule!

Breakout Sessions

AWS re:Invent breakout sessions are lecture-style and one hour long. These sessions are delivered by AWS experts and they typically include 10–15 minutes of Q&A at the end. For our virtual attendees, breakout sessions will be made available on-demand in the week after re:Invent.

Level 200 – Intermediate

  • OPN201 – How Apache Lucene’s community build merge-on-refresh

    This session provides an on-the-ground look at the inner workings of modern open-source development by following a significant, complex change from inception to release. In 2020, Amazon completed a multiyear migration of its customer-facing product search engine onto a new service based on Apache Lucene, supported by many AWS services. In production, Amazon observed Lucene’s segmented nature influencing query latency and had an idea to reduce its segment count. The idea seemed simple, but its realization, through close collaboration with the Lucene developer community, took nearly a year! This session dives deep into this journey.

  • OPN204 – Introduction to GraphQL

    GraphQL is an open-source API query language. This session provides an introduction to GraphQL theory and practice. Learn the three superpowers of GraphQL, how GraphQL compares to REST API, and how to take GraphQL into production.

  • OPN207 – Top 10 observability challenges and how open source can help

    When building and operating cloud-native applications, such as containerized microservices in Kubernetes or serverless applications, you don’t want to proceed by guesswork. In other words, you want to capture and collect all relevant signals (logs, metrics, traces) from your applications and infrastructure so that you can act upon it in a timely manner. This is called observability. In this session, you learn how open source can help with the top challenges in this space, including signal correlation, portability, and providing a single pane of glass.

Level 300 – Advanced

  • OPN301 – Using Rust to minimize environmental impact

    Rust is one of the most energy-efficient and safe programming languages. With Rust, it may be possible to reduce the environmental impact of the IT industry by 50% and prevent 70% of all high-severity CVEs. In this session, dive into the “super powers” of Rust, hear about the work ahead to give those powers to every engineer, and hear the ways you can contribute.

  • OPN307 – OpenSearch: Building the future of search together

    OpenSearch is a new community-driven, open-source search and analytics suite that makes it easy to securely ingest, search, and analyze data. In this session, dive deep into how OpenSearch was created. Gain insight into new functionalities being built for OpenSearch, including improved performance and reliability, lower cost at scale, observability analytics, machine learning capabilities, and extensibility enhancements designed to enable anyone to build and share their own OpenSearch products and features.

  • OPN308 – ML with Metaflow and Kubernetes: Prototype to production on Amazon EKS

    Data science is hard. At AWS re:Invent 2019, Netflix addressed the data science challenge by open-sourcing Metaflow, their human-centric framework for data science. Two years and 4,400+ GitHub stars later, Metaflow is helping other organizations standardize their data science pipelines and seamlessly move from prototype to production. However, a wider array of users results in a need for wider infrastructure support, and Metaflow is there to meet users where they are. This session explores data science pipelines on Amazon EKS and other open platforms and details how Metaflow is bringing its human-centric vision to the Kubernetes ecosystem.

Builders’ Sessions

Builders Sessions are small-group sessions led by an AWS expert who guides you as you work with an open source technology. Each builders’ session begins with a short explanation or demonstration of what you are going to build. Once the demonstration is complete, use your laptop to experiment and build with the AWS expert.

Level 300 – Advanced
