Cfengine Reborn – Keeping Promises
SELF-HEALING DATACENTER SOLUTION
Some users of Cfengine
SELF-HEALING DATACENTER SOLUTION
The future is not certain
• We encourage it but we do not decide it
• It is about simple patterns that are robust
• There are no guarantees, but we can try to keep promises
SELF-HEALING DATACENTER SOLUTION
Configuration Management
SELF-HEALING DATACENTER SOLUTION
Based on Promise Theory research
Puts goals not recipes in focus
– Goals are invariants, recipes depend on circumstances
– Simple connection to “Service Level Agreements”
– Easy to measure compliance A promise is a documentation item
– Knowledge integration
Promise Technology
SELF-HEALING DATACENTER SOLUTION
Cfengine aspects
SELF-HEALING DATACENTER SOLUTION
Promises focus on the end state (desired state) not on fragile procedures and baselines
We automate repair using Cfengine's published convergence principle
Convergence = self-healing
SELF-HEALING DATACENTER SOLUTION
Every node is responsible for its own state
– Allows flat scalability (no bottlenecks)
– Allows detailed adaptation to local environment (each host knows its own environment best)
Hosts subscribe to external resources they need
– Software Package manager integration
– Policy updates from orchestrator when available
Push attacks a system, pull grants autonomy to all parts of the network and it fault tolerant of network outage (for wireless, pervasive, field operations etc)
Pull not push – scale and security
SELF-HEALING DATACENTER SOLUTION
Agile, elastic scaling
