AWS re:Invent 2025: Why the future of the cloud is durable

AWS re:Invent 2025 in Las Vegas marked a significant shift in the software industry, focusing on scaling known patterns rather than questioning their existence. A pivotal moment was AWS's launch of Lambda Durable Functions, which validated the concept of Durable Execution as essential for reliable distributed systems, a model previously advocated by the author. The event also showcased the evolution of AI from basic chatbots to sophisticated agents, with discussions highlighting the importance of reliable infrastructure, such as Temporal's solutions, for AI functionality. The author noted strong community engagement and visibility, with events like the House of Kube party drawing large crowds, and a fleet of branded Ziggy cars serving both as attendee transport and promotional tools. The overall sentiment was optimistic, with expectations for continued growth in Durable Execution in the coming year, underscored by the support from cloud giants and the ongoing AI advancements.
