Adjusting IT resources to actual demand to reduce cost and secure performance, especially in cloud environments.
Rightsizing is the practice of adjusting resources and capacity to actual workloads to optimize cost, performance and utilization. Especially in cloud environments (VMs, containers, managed services) rightsizing reduces overprovisioning and improves reliability. It relies on monitoring data, historical metrics and iterative adjustments.
Mean CPU usage over a representative period to assess utilization.
Helps detect peak consumption without being dominated by outliers.
Monetary metric to evaluate the saving effect of rightsizing measures.
An online shop reduced instance sizes outside sales peaks after traffic analysis and lowered costs while maintaining availability.
By monitoring tenants, DB instances were grouped by load class and provisioned accordingly, improving performance and cost.
Batch clusters were scheduled and temporarily scaled up instead of permanently allocating large capacity.
