9. Document Model Benefits
• Agility and flexibility
9
– Data model supports business change
– Rapidly iterate to meet new requirements
• Intuitive, natural data representation
– Eliminates ORM layer
– Developers are more productive
• Reduces the need for joins, disk seeks
– Programming is more simple
– Performance delivered at scale

10. High Availability Through
Replication

11. Why Replication?
• How many have faced node failures?
• How many have been woken up from sleep to do
11
a fail-over(s)?
• How many have experienced issues due to
network latency?
• Different uses for data
– Normal processing
– Simple analytics

12. Replica Sets
12
• Replica Set – two or more copies
• Self-healing shard
• Addresses availability
considerations:
– High Availability
– Disaster Recovery
– Maintenance
• Deployment Flexibility
– Data locality to users
– Workload isolation: operational &
analytics

13. Replica Set – Creation

14. Replica Set – Initialize

15. Replica Set – Failure

16. Replica Set – Failover

17. Replica Set – Recovery

18. Replica Set – Recovered

19. Scalability Through Sharding

20. Working Set Exceeds Physical

• Automated failover
• Tolerates server failures
• Tolerates rack failures
• Number of replicas
defines failure tolerance

28. MongoDB Management Service

29. MongoDB Management Service
Management for MongoDB, created by the engineers who
develop the database
• Automation, for single-click
29
provisioning, scaling &
upgrades
• Monitoring, with charts,
dashboards and alerts on 100+
metrics
• Backup and restore, with point-in-
time recovery, support for
sharded clusters
