State Management

Sorna's states includes the followings:

• Global configurations - etcd
• Docker kernel images - etcd
• Available agent instances - etcd/Redis
• Kernel sessions - RDBMS
• API keypairs - RDBMS

Global configurations

• Deployed Sorna agent version
  • Each agent initiates auto-updates by watching this value from etcd.

Docker kernel images

• The list of docker kernel images
  • Each image has the target hash version for updates
  • Per-image requirements such as GPU required, compute-intensiveness, etc.

Available agent instances

• Instance capabilities such as GPU-enabled or not.
• Instance limits such as the memory size, the number of CPU cores, etc.
• Instance occupation such as the number of allocated cores, etc.

Kernel sessions and API keypairs

• Rate-limit information
• Key availability
• Occupation such as the number of concurrent sessions
• Accumulated usage tracking (e.g., total CPU time used)
