How an installation is laid out
The pieces of a G8 installation, where each kind of data lives, the topologies the guides install, what is highly available and what a backup covers.
How G8 handles a request
The way a request takes through the gateway, and the objects you create in the console along it.
Where a plugin runs
Route, service, plugin config, global rule, consumer and consumer group, and which copy of a plugin wins.
Authentication: consumers and credentials
How the gateway tells your clients apart, and what follows once it knows who is calling.
How the console writes to the gateway
What happens between saving an object in the console and the change on the gateway, and what the audit log records on the way.
Where request records go
How the gateway writes a record of each request into the environment's log store, how G8 reads it back, and when it is deleted.
Where the numbers come from
How the gateway counts and times requests, how Prometheus keeps those numbers, and how Analytics reads them.
