What is typically done to enhance the availability of a database system?

Using load balancing techniques is a well-established method to enhance the availability of a database system. Load balancing distributes incoming traffic or workload across multiple servers or instances of a database, ensuring no single server is overwhelmed. This redundancy helps to manage spikes in traffic gracefully and reduces the risk of downtime due to server overload. By balancing the load, services can remain operational even during high-demand periods and can also continue functioning in case one of the servers fails, as traffic can be rerouted to the remaining operational servers.

This approach aligns closely with availability objectives, as it allows for greater resilience and scalability of the database system, ultimately improving user experience and service delivery.
