Question

A company stores application log files in an S3 bucket. Logs are heavily analyzed for the first 30 days. Between 30 and 90 days they are accessed only occasionally for troubleshooting, and must be retrievable within milliseconds when needed. After 90 days, logs are almost never accessed but must be retained for 7 years for compliance, where retrieval times of several hours are acceptable. Which lifecycle configuration minimizes storage cost while meeting these access requirements?
