Which configuration strategy is used to handle high demand during peak times by adding more server instances?

The configuration strategy that effectively addresses high demand during peak times by adding more server instances is horizontal scaling based on a schedule. This approach involves increasing the number of servers or instances to manage increased traffic or workloads, thereby distributing the load across multiple servers.

Horizontal scaling is particularly beneficial in cloud environments, as it allows for increased capacity without the need for significant changes to the existing infrastructure. By deploying additional instances ahead of predictable peak times—such as during a sales event or end-of-quarter reporting—organizations can ensure that they maintain performance levels and availability for users.

This scheduled aspect means that the scaling can be anticipated and automated, reducing the need for manual intervention and minimizing the risks of server overload during sudden traffic surges. By proactively managing resources, businesses can optimize costs and performance effectively.
