AWS re:Invent is an annual gathering of tens of thousands of AWS staff, partners, and users for a full week of keynote sessions, feature announcements, customer case studies, hands-on workshops, and more. The sponsor hall offers a great way to learn about the newest AWS features and partner products, while conference sessions can be educational and inspiring. Some interesting sessions include "Using deep learning to track wildfires and air quality" which discusses using satellite imagery and meteorological data to predict wildfires and air quality in real time; "Refactoring a monolith to serverless in 8 steps", which outlines discrete steps for successfully refactoring a monolith to serverless; and "Scaling to billions of requests the serverless way at Capital One", which explores how Capital One used serverless streaming architecture to provide real-time insights for millions of customers. Additionally, there are sessions on chaos engineering in a serverless world, BPF performance analysis, and partnerships between AWS and Datadog, including sessions on using observability tooling to build confidence and accelerate migrations.
