Autoscaling

What is Autoscaling?

Autoscaling (auto-scaling, auto scaling or automatic scaling) is a cloud computing method to dynamically and automatically adjust computational resources within a server farm based on the load, typically measured by the number of active servers.

Autoscaling is useful when a site or application needs additional server resources to satisfy additional page requests or processing jobs. Autoscaling is typically used to handle sudden traffic bursts or spikes but is also useful when designing a scalable architecture to manage longer term resource growth.
