MongoDB Management Service makes operations effortless, reducing complicated tasks to a single click. You can now provision machines, configure replica sets and sharded clusters, and upgrade your MongoDB deployment all through the MMS interface. We'll walk through demos of all the new MMS features, including provisioning, expanding and contracting a cluster, resizing the oplog, and managing users.

3. What is MMS?

12. MMS Monitoring

13. Topology

14. Charting

15. Alerting

16. 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.

17. MMS Backups

18. Disasters: All Shapes & Sizes

19. Disasters: Many Causes

20. Risks Are Everywhere
Storage
failures
Power
outages
Programmer
error
Hardware
failures
DC failures
Cyber
attacks
Weather

21. Replication
• Redundant copies of your data across
– Servers
– Racks
– Data Centers
• Automatic failover
• Tunable consistency minimizes risk
• However…programmer errors will replicate almost
immediately!

22. Backups
Backing up data is one way to ensure availability and
lower risk. They require active engagement,
otherwise:
• Backups can be outdated
• Process can be slow (backup or restore)
• Isolated
• …but they are relatively inexpensive and do well at
minimizing risk

24. MMS Maintenance Operations

25. 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/

26. Step 1 – Stop A Secondary

27. Step 2 – Restart As Standalone

28. Step 3 – Perform Maintenance

29. Step 4 – Restart As Member of Replica
Set

30. Step 5 – Work on Primary Last

31. Demo

32. Operations
• Upgrade/Downgrade
• Add replica
• Add shard
• Remove shard
• Resize oplog
