DESCRIPTION
MMS is the application for managing MongoDB, created by the engineers who develop MongoDB. Using a simple yet sophisticated user interface, MMS makes it easy and reliable to run MongoDB at scale, providing the key capabilities you need to ensure a great experience for your customers. MMS is delivered as a fully-managed, cloud service, or an on-premise software for MongoDB Subscribers. See more at: http://www.mongodb.com/mongodb-management-service#sthash.1D1Q1ts0.dpuf This session introduces MMS, helps you to understand at a high level what it does, add users and permissions, and shows how to get started with downloading and installing the agents. Presented by, Sam Weaver: Sam Weaver is a Senior Solution Architect at MongoDB based in London. Prior to MongoDB, he worked at Red Hat doing technical pre-sales on the product portfolio including Linux, Virtualisation and Middleware. Originally from Cheltenham, England he received his Bachelors from Cardiff University and currently lives in Camberley, Surrey.

Sam Weaver, Senior Solution Architect
#MongoDBWebinars #MongoDBManagementService
Welcome3 part webinar series over the next 3 weeks
• Week 1: Introduction to MMS
• Week 2: Backup your data with MMS– How the backup solution works– Backing up a replica set– Backing up a sharded cluster– Restoring your data
• Week 3: Monitoring and alerting with MMS– Charts– Alerts– Interpreting the data
Agenda for today
• High level tour of MMS
• Getting started with the agents
• Quick look into monitoring and backup – more on these in the next session
What is MMS?
• Software built by MongoDB FOR MongoDB
• Makes your operations easier
• Can be run on-premise or in the cloud
MMS Then…
MMS Now….
Getting Started
Firstly.. Sign up..
Welcome screen..
Begin Setup..
Select an OS
Verify the agent..
Add and verify hosts
And if all goes well…
Great! Now what?
Notice..
Clicking on the host gives you metrics
Why Monitoring?
Cant fix what you don’t know about
Capacity planning
Pre-empting problemsProactive support
2-way mirror with commercial support
Bottom Line?
• MongoDB ops will live in this tool
• See what’s going on with your entire cluster
• In more detail with less effort than other 3rd party tools
• Pressure to extend MMS to other tools, done via SNMP and API on roadmap, will be GA in June/July
Your activity feed
Set alerts
Why Alerting?
Alerts on a huge range of metrics– Host metrics– Replica set– Agent– Backup
Send alerts via SMS, Email, PagerDuty and HipChat
Bottom Line?
• Sleep easy knowing we will tell you what’s going on as it happens
• Integrate with your existing alerting (pager duty, hip chat)
Users
Add users
User Roles
• Different members of your team can do different things– Owner– Automation admin– Backup admin– Monitoring admin– User Admin– Read only
Bottom Line?
• Multiple people can admin different parts of the system.
• Work as one team, with set responsibilities for each
Backup
• Risks– Storage failure– Power outage– Programmer error– Hardware failure– Data centre failure– Cyber attack– Weather related incidents
• Storage level options
• MongoDB Backup Service
Availability and Durability
• Relative to any particular risk– How much data can you afford to lose? (RPO)– How long can you afford to be offline? (RTO)– What price are you willing to pay to remove the
risk?
• Solutions– Replication– Application engineering?– Backup
Addressing Risks
Replication
• Built into MongoDB, only ops and infrastructure cost
• Very little to zero data loss in failure
• Down for a very short interval
• BUT… programmer errors will replicate almost instantly
Traditional Backup
• Slower to restore
• Can suffer from being out of date
• Fairly cheap
• Isolated
• Covers most risks
• Mongodump/mongorestore
• Storage level options
• MongoDB Backup Service
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
Recovery Approaches
Installing the agent..
Download and extract…
Verify agent and host
Select what you want to backup
Exclude certain name spaces
If its successful..
Snapshots…
Backing up a sharded cluster
Sharded Clusters
• Now only a few clicks:– Balancer paused every 6 hours – A no-op token is inserted across all shards,
mongoses and config servers– Oplog applied to replica sets until point in which
token was inserted
• Provides a consistent state of database across shards
Bottom line: MMS Backup
• Simplest means of backing up your database
• Peace of mind, it just works
• Point-in-time for replica sets
• Check points for clusters
• Spin up developers quickly from snapshots
Automation
Automation
Will be released in summer
Deploy replica sets, & shards at the click of a button
Double the size of your estate easily
Upgrade versions quickly and safelyManual process of rolling upgrades 12-15 steps
