Autoscale
Autoscale is the automatic adjustment of computing resources in response to workload changes to maintain performance while controlling costs. It can scale horizontally by adding or removing instances or containers, or vertically by increasing or decreasing resources on individual instances. The goal is to match supply to demand without manual intervention.
A controller collects metrics such as CPU utilization, memory usage, request rate, queue depth, or application-specific
Common implementations exist for cloud infrastructures, on-premise clusters, and hybrid environments. Cloud providers offer autoscaling groups
Benefits include improved application performance during demand spikes and reduced costs during troughs. Limitations include potential
Use cases include web front-ends with variable traffic, API services, batch processing jobs, and microservice architectures
