Session Overview by Engineer Hamasaki

In this session titled "Introduction to AWS Cost Analysis - Understanding Why Costs Are High Before Reducing Them", Hamasaki will delve into the complexities of AWS cost management.
Many existing books and articles on AWS costs tend to focus mainly on visualizing expenses and pinpointing specific service reduction techniques. However, in real-world scenarios, decision-makers often struggle with fundamental questions: "Is this cost really high?" "Is it reasonable to target for reduction?" and "What exactly is creating a bottleneck?"
This session will emphasize the critical analysis phase that exists between visualization and cost reduction, aiming to help professionals grasp the reasons behind incurred costs in a structured manner. Attendees will learn about effective methodologies for making informed decisions regarding cost management and analysis.
