Azure Autoscale
Azure Autoscale is a cloud service feature within Microsoft Azure that automatically adjusts the number of compute resources (such as virtual machines or app service instances) based on predefined rules or metrics, such as CPU usage or queue length. It helps applications maintain performance during traffic spikes and reduce costs during low-demand periods by scaling resources in or out dynamically. This service is integrated with various Azure compute services like Virtual Machine Scale Sets, App Service, and Azure Kubernetes Service.
Developers should use Azure Autoscale to ensure application reliability and cost-efficiency in cloud environments, particularly for workloads with variable or unpredictable traffic patterns, such as e-commerce sites, SaaS applications, or batch processing jobs. It automates scaling decisions, reducing manual intervention and minimizing downtime or performance degradation during demand surges, while optimizing resource usage to avoid over-provisioning.
