  1. 1. Cfengine Reborn – Keeping Promises SELF-HEALING DATACENTER SOLUTION
  2. 2. Some users of Cfengine SELF-HEALING DATACENTER SOLUTION
  3. 3. 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
  4. 4. Configuration Management SELF-HEALING DATACENTER SOLUTION
  5. 5. Promise Technology  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 SELF-HEALING DATACENTER SOLUTION
  6. 6. Cfengine aspects SELF-HEALING DATACENTER SOLUTION
  7. 7. Convergence = self-healing  Promises focus on the end state (desired state) not on fragile procedures and baselines  We automate repair using Cfengine's published convergence principle SELF-HEALING DATACENTER SOLUTION
  8. 8. Pull not push – scale and security  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) SELF-HEALING DATACENTER SOLUTION

  10. 10. Knowledge Management SELF-HEALING DATACENTER SOLUTION
  11. 11. Reporting – Knowledge Management SELF-HEALING DATACENTER SOLUTION
  12. 12. Unique self-building documentation SELF-HEALING DATACENTER SOLUTION
  13. 13. Cfengine Nova Extras • Now – One touch bootstrap – Self-knowledge / analysis document integration – Ultra lightweight monitoring integrated – Native cross-platform support includes Windows – Enhanced security (FIPS) – Directory service integration with fault tolerance – Virtualization and elastic scaling support • 3-6 months – Cfengine 2 to Nova conversion – GUI “helm” single point of contact and change SELF-HEALING DATACENTER SOLUTION
