Overview of Resource Optimization

What Is Resource Optimization?

Cost Center monitors your historical expenditures and resource usage, identifies idle resources, checks resource status, and produces optimization recommendations for you to find cost-saving opportunities.

Currently, resource optimization recommendations are only available for the following cloud services:

  • EIP: Optimization Advisor (OA) checks whether there are EIPs not bound to any instances. If there are, optimization recommendations are provided for such EIPs. You can determine whether to apply the recommendations based on the displayed time range and estimated monthly savings.
  • ELB: OA checks whether there are load balancers not associated with any backend servers. If there are, optimization recommendations are provided for such load balancers. You can determine whether to apply the recommendations based on the displayed time range and estimated monthly savings.
  • EVS: OA checks whether there are EVS disks not attached to any servers. If there are, optimization recommendations are provided for such EVS disks. You can determine whether to apply the recommendations based on the displayed time range and estimated monthly savings.

Enabling Resource Optimization

To enable resource optimization for EIP, ELB, and EVS services, click enable OA for free on the Cost Optimization page in Cost Center.

What Are Idle EVS, EIP, and ELB Resources?

If resources are not bound or attached to any instances, they are identified as idle resources.

  • EVS: EVS disks that have not been attached in the last seven days are considered idle.
  • EIP: EIPs that are detected not bound during resource checks are considered idle.
  • ELB: During resource checks, if load balancers are detected not associated with any backend server group or not bound to any backend server, they are considered idle.
