MMS: The Easiest Way to Run MongoDB
- 1. MMS: The Easiest Way to Run MongoDB Daniel Coupal #mongodb Technical Services Engineer, MongoDB
- 2. What is MMS?
- 3. What WAS the MongoDB Management Service? • Last month,the MongoDB Management Service was a web-based tool that allowed you to Monitor and Backup your MongoDB deployment. • You created your deployment,in any size or shape, then you used MMS to Monitor or Backup your deployment.
- 4. What did we change? • MMS is now a web-based tool that starts with you from the beginning of your MongoDB deployment lifecycle. • Now you use MMS to build your deployment,and then continue to use MMS to manage its lifecycle (including Monitoring and Backup!)
- 5. Why the change? 1. MMS was arriving in the user’s life a little“late to the party”. Mistakes had already been made. User might already some misconceptions or frustrations with MongoDB. 2. Previous version of MMS could monitor critical operations (maintenance,upgrades,etc.),but not actually help!
- 7. And run a very large MongoDB deployment of their own!
- 13. MMS Monitoring
- 14. Topology
- 15. Charting
- 16. Alerting
- 17. Proactive Support MongoDB offers Proactive Support for Subscription Customers.Our engineers can monitor your deployment and make suggestions in order to tweak for better performance or avoid doom.
- 18. MMS Backups
- 19. Risks Are Everywhere Storage failures Power outages Programmer error Hardware failures AWS Mandatory Reboots Datacenter failures Cyber attacks Weather
- 20. Replication • Redundant copies of your data across – Servers – Racks – Data Centers • Automatic failover • Tunable consistency minimizes risk • However…programmer errors will replicate almost immediately!
- 21. Backups Backing up data is one way to ensure availability and lower risk. Effort is required to ensure that your backup system is always running and that the backups are correct.
- 22. MongoDB Backup Approaches mongodump File system MMS Backup Initial complexity Medium High Low Confidence in Backups Medium Medium High Point in time recovery of replica set Sort of ☺ No Yes System Overhead High Can be low Low Scalable No With work Yes Consistent Snapshot of Sharded System Difficult Difficult Yes
- 24. The Process • Applies to upgrades and most maintenance tasks • Careful order of steps is critical – Especially in sharded clusters! • For each shard/replica set – For each replica set member • http://docs.mongodb.org/manual/tutorial/perform- maintence-on-replica-set-members/
- 25. Step 1 – Stop A Secondary
- 26. Step 2 – Restart As Standalone
- 27. Step 3 – Perform Maintenance
- 28. Step 4 – Restart As Member of Replica Set
- 29. Step 5 – Work on Primary Last
- 30. Demo
- 31. Operations • Upgrade/Downgrade • Add replica member • Add shard • Remove shard • Resize oplog
- 32. Resources • MMS – mms.mongodb.com – mms.mongodb.com/help • MMS On-Premise – Available for evaluation – mms.mongodb.com/help-hosted
