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


Configuration Management


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


Cfengine aspects


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


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


Agile, elastic scaling

?
