Definition
The aggregation and storage of all application, system, and audit logs from hundreds of different cloud servers into one single, searchable, highly durable location.
Explain Like I'm New
Instead of checking the security camera tapes in 50 different buildings, you wire all the cameras to stream to one massive TV in a central security room so you can search them all at once.
Real World Example
AWS CloudWatch Logs, Azure Log Analytics. Your app runs on 10 different servers. A user complains they got an error. Instead of logging into all 10 servers manually to read text files, you search for the user's ID in CloudWatch Logs, and it instantly finds the exact server and the exact error line.
Common Use Cases
- •Debugging distributed systems
- •Security auditing
