This session aims to simplify how we understand the costs associated with serverless architectures by focusing on their unique pricing models and how to manage costs better. We'll look at the main factors that affect serverless costs, such as the number of requests, how long these operations run, and how resources are used. Through real-life examples, we'll highlight common mistakes and share the best ways to keep costs down. The talk will also introduce tools and techniques to help track and reduce expenses in serverless setups, giving attendees practical tips to improve their serverless operations economically. This session is perfect for architects, developers, and finance teams who want to use serverless technology efficiently without overspending or sacrificing quality.
