What is database load balancing and why is it important?

Database load balancing is the process of distributing database requests across multiple servers to ensure optimal performance and reliability. It's important because it helps prevent any single server from becoming a bottleneck, improves response times, and enhances fault tolerance.

How does load balancing improve database performance?

Load balancing improves database performance by distributing incoming queries evenly across multiple servers, which reduces the load on any single server. This leads to faster query response times and better resource utilization.

What are some common techniques used for database load balancing?

Common techniques include round-robin distribution, least connections, and IP hash. Each method has its own advantages depending on the specific use case.

Can you explain how to implement load balancing in a cloud environment?

In a cloud environment, you can implement load balancing by using cloud provider services like AWS Elastic Load Balancing or Azure Load Balancer. These services automatically distribute traffic and can scale resources based on demand.
