AWS re:Invent is the largest cloud computing event worldwide, and the Gremlin team provides several engaging activities to attendees to enhance their experience, including a booth at the Expo, a Chaos Engineering-themed memory challenge, and a Reliability Tour with stops at various partner locations. The Reliability Tour offers participants a chance to win prizes by collecting enamel pins from different tour stops, including Gremlin's booth, MongoDB's Pub Crawl, and others. Attendees can also participate in hands-on workshops, such as running Chaos Engineering experiments on Amazon EKS, and attend reliability-focused talks. Additionally, there are opportunities for networking and socializing, such as a Pub Crawl event with MongoDB and Datadog. For those new to the event, resources like A Cloud Guru's guide can help navigate the overwhelming experience, and Gremlin encourages participants to start a free trial of its platform to find and fix availability risks proactively.
