Clarify the stress characteristics of the business systems to be migrated, including but not limited to average CPU/memory usage, usage peaks, average network throughput and throughput peaks, storage usage trends, average storage stress and storage stress peaks, number of concurrent business users, business data increment, and peak business cycles. These details provide data support for future resource planning. Specifically, the following information about the business systems to be migrated should be collected:
Information Collection
Information Purpose
Average CPU/memory usage and peak usage during peak periods
Evaluate whether to scale up or down the VM specifications after business migration
Average network bandwidth usage and peak usage during peak periods
Assess the need for bandwidth guarantee for critical businesses
Storage usage trends and peak IO load during peak periods
Plan the storage quota and storage characteristics of the VM after migration
Number of concurrent business users, business increment, and peak business cycles
Used to analyze customer business bottlenecks and optimize the VM
