The type and scale of conferences vary. For example, AWS re:Invent is an annual week-long conference that brings tens of thousands of tech and business enthusiasts together with hundreds of sessions spread over five days, whereas AWS Summits and AWS Community Summits are local events—mostly one-day—conducted around the world to bring the community and technology experts closer. Most of the content gets shared online as well. AWS Events and Webinars is a good place to identify events that might suit your purposes.
