Evaluating Alibaba Cloud SLS as an Incident-Response Logging Architecture
Collecting logs is easy.
Using them effectively during a production incident is much harder.
In a distributed system, a single user request may pass through several services, Kubernetes pods, network layers, databases, queues, and external dependencies. When something starts failing, engineers can quickly find themselves searching through thousands or millions of log entries without knowing which ones actually matter.

Alibaba Cloud's Simple Log Service (SLS) is designed around that broader problem. SLS is a cloud-native observability platform for collecting, processing, querying, analyzing, visualizing, and alerting on logs, metrics, traces, and events.
I wanted to examine SLS from an SRE perspective—particularly what changes when logging becomes part of...
