The document provides an overview of MongoDB administration including its data model, replication for high availability, sharding for scalability, deployment architectures, operations, security features, and resources for operations teams. The key topics covered are the flexible document data model, replication using replica sets for high availability, scaling out through sharding of data across multiple servers, and different deployment architectures including single/multi data center configurations.

- 10. Document Model Benefits • Agility and flexibility –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 9
- 11. Replication
- 12. Why Replication? • High Availability (HA) through data duplication • Distributed access at low latency • Workload isolation – OLTP, Query, Analytics 11
- 13. Replica Sets Application 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 Driver Primary Secondary Secondary Replication
- 14. Replica Set – Creation
- 15. Replica Set – Initialize
- 16. Replica Set – Failure
- 17. Replica Set – Failover
- 18. Replica Set – Recovery
- 19. Replica Set – Recovered
