Transcript

1. Dingo PostgreSQL Implementing “Undo” for 
 Cloud Foundry Service Brokers Justin Carter & Dr Nic Williams
2. Dingo PostgreSQL Problem
3. Dingo PostgreSQL Problem
4. Dingo PostgreSQL Problem
5. Plan  First-class love for databases Implementing “undo” Ǚ No CF CLI plugin required Example of Dingo PostgreSQL
6.  For the love of databases Cloud Foundry loves developers
7.  For the love of databases  Does Cloud Foundry love DBs?
8. 361 v2 API endpoints  For the love of databases 81 v2 services APIs
9.  For the love of databases 51 v3 API endpoints 4 v3 APIs for service bindings
10.  For the love of databases 172 cf commands 31 cf commands for ‘services’
11.  For the love of databases  Create service instance Bind to an application Unbind from an app Delete service instance Ǚ
12.  For the love of databases Dz 0 commands for listing backups 0 commands for viewing DB logs 0 commands for health/monitoring ǟ 0 commands to “undo” mistakes Ǚ
13.  For the love of databases TCP router is for apps Diego persistence is for apps  Loggregator is app centric CLI plugins decoupled from brokers Lj
14.  Undo  How can we offer “undo” to users?
15.  Undo Ŏ “clone-from” parameter
16. Idea Perform “actions” via parameters
17. Problem ŏ Broker only receives UUIDs,
 not “production” provided by user ŏ Cloud Controller doesn’t remember 
 “production” after delete
18. Implement broker 1 Receive service instance ID only 3 Look up service name from CF 2 Continue asynchronously 4 Cache service name
 independently of CF
19. CLI to Cloud Controller
20. Cloud Controller to Broker
21.  Undo Ŏ Able to map “production” to backups
22. clone-from: production
23. Space restriction Ȓ Restrict to same space_guid Else complex authorisation system
24. “Daily” backups Ɍ Daily backups can be 23+ hours old
25. … Continuous archiving …  PostgreSQL write ahead logs (WAL) MySQL binary log files  MongoDB /dev/null Ǚ
26. Dingo PostgreSQL Dingo PostgreSQL <insert video of 3D animation>
27. User Experience  User-initiated data recovery Continuous/near-real time archives …  Users expect all data is recoverable  ȑ Native CLI experience would be much nicer please
28. Future Auto-discovery of broker plugin Point in time recovery … CLI plugins for full experience Lj  Operator cleanup of legacy backups  Ǎ
29. Team 30 staff, 6 countries Platform experts Cloud Foundry experts Dingo PostgreSQL
