AWS re:Invent 2021 marks its 10th anniversary and is one of the first major in-person events since 2019, offering a mix of in-person and virtual experiences. Gremlin is participating by hosting the AWS Financial Services GameDay, a hands-on learning experience focused on using AWS services for financial analytics, machine learning, and resilience testing. Attendees can visit the Gremlin booth for demos, participate in raffles, and join the Resiliency Tour to win Amazon gift cards. Additionally, there's an after-party hosted by Gremlin and partners. The event offers various resources, including guides from AWS Heroes and a comprehensive session catalog, to help attendees navigate the conference. Health measures are in place to ensure safety, and those unable to attend in-person can participate virtually for free. Gremlin also offers a free trial of their platform to help users find and mitigate availability risks, highlighting the importance of building testable, reliable systems.
