The primary and standby cluster MongoDB members are in the same MongoDB replica set. The standby cluster members are configured as [hidden](https://www.mongodb.com/docs/manual/core/replica-set-hidden-member), [delayed](https://www.mongodb.com/docs/manual/core/replica-set-delayed-member/), and with [zero priority](https://www.mongodb.com/docs/manual/core/replica-set-priority-0-member/). When the primary cluster goes down, the standby cluster MongoDB members are promoted to standby state—one of them will become primary by administrator. After the primary is back online, the primary cluster members will be demoted to hidden. For switching back, the primary cluster members will be promoted to secondary MongoDB members and standby cluster members will be demoted. **This approach is supported by the plgd hub helm chart because it complies with the MongoDB Community Server license.** For setup instructions, please refer to this [tutorial]().
