MongoDB
MongoDB service used by many platform services.
Downtime
Platform down
Downtime is absolutely forbidden. No platform service would function.
We recommend:
- Backup your MongoDB at least daily.
- Use passive replica-set member for backup to avoid overwhelming the system during the process.
Scaling
For the production installation:
- Must run in replication (replica set) to ensure the high availability (HA) of the service.
- Replica set must have 3, 5, etc members to ensure decision quorum.
- Add one
passive mongo instance to backup from it (for example 3+1 system).
Deployment
Deployed and installed on the separate Virtual Machines to ensure HA.
