In this AWS re:Invent 2023 session, Steven Follis and Skylar from Smartsheet discuss how to achieve significant cost reductions and improve efficiency using AWS Fargate. Skylar shares Smartsheet's journey of optimizing their infrastructure, propelling their deployment capabilities, and scaling their services using a cell-based architecture. The presentation covers how Smartsheet leveraged Fargate, Graviton, and other AWS services to reduce costs by 70%, increase deployment frequency, and scale their grid service from 1,000 to 50,000 requests per second. Key takeaways include embracing autoscaling, understanding AWS billing, and adopting a cell-based architecture for improved scalability and efficiency.
