Building Return on Investment from Cloud Computing – Cloud Computing Key Performance Indicators and Metrics
Cloud Computing introduces an expanded context for service-oriented business and IT.
Developing ROI models that show how Cloud Computing adoption can benefit both business and IT consumers and providers involves examining the key technology features and business operating model changes.
This section gives an overview of ROI models to support Cloud Computing assessments and business cases in two aspects:
- Key Performance Indicator ratios that target Cloud Computing adoption, comparing specific metrics of traditional IT with Cloud Computing solutions. These have been classified as cost, time, quality, and profitability indicators relating to Cloud Computing characteristics.
- Key Return on Investment savings models that demonstrate cost, time, quality, compliance, revenue, and profitability improvement by comparing traditional IT with Cloud Computing solutions.
The overview of Cloud Computing ROI models considers both indicators and ROI viewpoints.
Figure 12 shows an overview of Cloud Computing ROI models and KPIs.
Cloud Computing ROI Models and KPIs
Cloud ROI Cost Indicator Ratios
Figure 13 shows the cost indicator ratios, and outline explanations are given below.
Cloud Computing ROI Models – Cost Indicator Ratios
Availability versus Recovery SLA
- Indicator of availability performance compared to current service levels
Workload – Predictable Costs
- Indicator of CAPEX cost on-premise ownership versus Cloud
Workload – Variable Costs
- Indicator of OPEX cost for on-premise ownership versus Cloud; indicator of burst cost
CAPEX versus OPEX Costs
- Indicator of on-premise physical asset TCO versus Cloud TCO
Workload versus Utilization %
- Indicator of cost-effective Cloud workload utilization
Workload Type Allocations
- Workload size versus memory/processor distribution; indicator of % IT asset workloads using Cloud
Instance to Asset Ratio
