Signs and flags announcing the ongoing re:Invent event were displayed throughout the hotel.

The annual flagship global event of AWS, re:Invent, kicked off on December 1. Every year, cloud experts from around the world gather in Las Vegas, USA, to share the latest technologies and trends in the cloud industry. This year's event, held over four days at The Venetian hotel and other venues throughout Las Vegas, features more than 3,000 sessions. On the opening day alone, approximately 50,000 people are expected to visit the venue.

Even before the official opening of the event, participants were already lining up at the entrances of conference rooms where lectures would be held, waiting to enter. The massive hotel, with a total area of about 210,000 square meters (approximately 63,000 pyeong) and more than 350 conference rooms, was packed with attendees. The event itself was not a typical stiff conference, but rather resembled a theme park, with various attractions set up throughout the venue. A slide was installed on the stairs from the second floor to the first floor of the main hall for visitors to enjoy. There were also numerous hands-on corners where participants could experience activities such as nail art, tattoos, and creating their own fragrances.

Developers from Korean companies also attended the event. Park, a developer from a Korean tech startup who visited re:Invent, said, "I came because I was interested in the multimodal artificial intelligence (AI) session, and I was surprised by the sheer scale of the event." He added, "I had only watched the event through online broadcasts before, but this is my first time attending in Las Vegas, and I heard that the keynote sessions are incredibly immersive," expressing his anticipation.

The core themes of this year's re:Invent are expected to be 'Agentic AI' and 'Physical AI.' Agentic AI refers to AI that goes beyond simply responding to user requests, predicting user actions, planning complex tasks, and even executing them. Discussions will also focus on Physical AI, a topic that has recently become a hot issue in the AI industry. Related infrastructure, such as chipsets like GPUs and data centers, will also be major topics of discussion.

The keynote speeches by key AWS executives are also focused on AI. On the second day of the event, December 2, AWS CEO Matt Garman will unveil the roadmap and major new services in the field of generative AI. He will also introduce the latest technological advancements in AWS's computing infrastructure for AI services. On December 3, Swami Sivasubramanian, Vice President of Agentic AI, will deliver a keynote on 'The Future of Agentic AI,' discussing how Agentic AI will transform the way we work and live. On the final day, December 4, Amazon CTO Werner Vogels will present 'New Architectural Principles for Developers in the AI Era,' outlining the design principles for AI systems.

Korean companies are also participating in re:Invent. Companies such as Samsung Electronics, Twelve Labs, Megazone Cloud, Woowa Brothers, and Toss are showcasing their technological capabilities as AWS partners at the event. AWS partners are sharing their innovation cases at this event. Samsung Electronics will present a case study on optimizing large-scale cloud infrastructure using AWS services, while Toss will share its experience automating app testing using the Amazon Nova model. Twelve Labs, which is developing its own Video Foundation Model (VFM), unveiled its latest model, 'Marengo 3.0,' supplied through AWS Bedrock.
