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!
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.
20. Replication
?? Redundant copies of your data across
¨C? Servers
¨C? Racks
¨C? 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.

24. The Process
?? Applies to upgrades and most maintenance tasks
?? Careful order of steps is critical
¨C? Especially in sharded clusters!
?? For each shard/replica set
¨C? For each replica set member
