AWS Lambda is introducing 1-Click Clusters, which provide on-demand access to large AI model training clusters featuring interconnected NVIDIA H100 Tensor Core GPUs. This feature allows ML teams to spin up short-term GPU clusters without long-term contracts, enabling them to focus on core workflows rather than infrastructure management. The clusters come pre-installed with popular AI frameworks and have a reservation minimum of only one week, making it easy for engineers to request access to the resources they need. Lambda's 1-Click Clusters are designed to provide high performance, ease of use, and flexibility, catering to both ML researchers and DevOps teams.
