The document outlines the capabilities of MongoDB Management Service (MMS) automation, which allows users to create, manage, and upgrade MongoDB systems seamlessly via a web interface. It details integration with cloud services for provisioning, provides features like user authentication management, and supports storage engine conversions. Additional functionalities include automated repairs for out-of-sync config servers and a demo automation API for advanced operations.
MMS Automation In Action!
- 2. MMS: MongoDB Management Service
- 3. MMS Automation ● Create MongoDB systems of any size, and any configuration ● Manage MongoDB systems, such as adding capacity or resizing the oplog, with no application downtime ● Upgrade a deployment, with no application downtime … all from the comfort of your web browser.
- 4. MMS Provisioning Integration with Amazon AWS that allows you to provision the servers on which your MongoDB processes will run, directly from MMS. ● Optional component - you can provision your base servers any way you like, doing it via MMS Provisioning is just one way ● Future plans to integrate OpenStack, Azure, Digital Ocean, etc.
- 5. MMS Automation : Why? ● Ease of operation ○ Some operations are easier to script than others...
- 6. MMS Automation : Why? ● Ease of operation ● Expect the unexpected
- 7. MMS Automation : Why? ● Ease of operation ● Expect the unexpected ● Reliability
- 8. MMS Automation : Why? ● Ease of operation ● Expect the unexpected ● Reliability ● Mongo expertise

- 17. New Features
- 18. Import Existing ● Start managing a pre-existing repl set or cluster with automation.
- 19. Demo
- 20. Authentication and Authorization ● Automation supports adding, editing, and removing users and custom roles. ● Works with standalone instances, replica sets, and sharded clusters. ● Works with all versions of MongoDB that Automation supports: 2.4, 2.6 and 3.0 ● Delayed auth schema upgrades are supported
- 21. Storage Engine Conversion ● Pluggable storage engines are a new feature in MongoDB 3.0 ● Automation supports converting between MMAPv1 and WiredTiger storage engines.
- 22. Storage Engine Conversion for Replica Sets
- 23. P S2 S1
- 26. P S2 S1 Start mongod with new storage engine
- 27. P S2 S1 Wait for initial sync
- 28. P S2 S1
- 29. P S2 S1
- 30. P S2 S1
- 31. P S2 S1
- 32. PS1
- 33. PS1
- 34. S2 PS1
- 35. S2 PS1
- 36. Storage Engine Conversion (standalone instances) 1. Stop mongod 2. Start mongod on a different port 3. Run mongodump 4. Stop mongod 5. Remove files under the dbpath 6. Start mongod with new storage engine setting (still on the different port) 7. Run mongorestore 8. Restart mongod on its original port
- 37. Repair Config Server Automation will automatically detect if a config server gets out of sync, and repair it
- 38. Repair Config Server 1. Detect that config server is out of sync by comparing dbhash against other dbhashes
- 39. Repair Config Server 2. Figure out which dbhash is correct ● Ignore if data size < 90% max data size ● If two agree, assume they are correct ● If none agree, choose “the first”
- 40. Repair Config Server 3. Repair config server : ● shut down ● mongodump from a good server ● start up on ephemeral port ● mongorestore ● verify dbhash correct ● restart on normal port
