Cost Explorer shows a sharp rise in data-transfer charges tied to a public S3 access pattern for a citizen media site. What should architects do first as part of cost and usage monitoring?

Short Explanation
When the water bill spikes, you find the open hydrant before you argue about the rate. Cost Explorer shows the data-transfer jump from that public S3 pattern — then you fix the pattern.
Full Explanation
Task 1.5 emphasizes monitoring cost and usage with tools such as Cost Explorer to identify drivers like data transfer. Visibility comes before remediation: quantify the public S3 transfer pattern, then redesign access (for example CloudFront, private patterns, or fewer cross-Region pulls). Hiding Cost Explorer or changing storage classes without diagnosing transfer causes misses the actual cost driver.
