Log Insight 2.0 introduced the ability to scale-out in addition to scale-up. With this change, a Log Insight instance is capable of playing different roles or service types. These include:
- Standalone (available in 1.x)
- Master (new in 2.0)
- Worker (new in 2.0)
NOTE: Service types should not be confused with node types. Every Log Insight instance (or node) is capable of running any service it is matter of what service is enabled on the node.
I would like to discuss the differences between these service types and some important considerations to keep in mind.
