Disadvantages of Hot Standby
- Cost: Setting up a backup system that is kept in standby mode and receives regular updates is necessary for hot standby mode implementation. However, both systems’ upkeep can be costly.
- Configuration: To ensure that the hot standby system can seamlessly take over the activities of the primary system, the configuration can be a challenging procedure that calls for careful planning.
- Testing: Frequent testing is necessary to make sure the hot standby system is prepared to take over in the event of a breakdown. This may increase the overall cost of putting hot standby mode into place.
- Scalability: Hot standby mode may not be the ideal choice for systems that need high scalability, even though it is useful for guaranteeing high availability.
What is Hot Standby Mode?
In high-availability systems, Hot Standby Mode is a type of redundancy and failover strategy used to ensure continuous operation and minimize downtime in the event of a failure. The term “Hot Standby” refers to a secondary system that is kept ready or on standby and can take over the primary system’s operations in the event of a failure.
