# [Corestack] Downsize underutilized Virtual Machines in Azure

The platform identifies underutilized Virtual Machines in Azure environments and recommends downsizing these VMs to more appropriate instance sizes. Failing to optimize VM sizes leads to unnecessary resource consumption, increased costs, and excessive carbon footprint.

## Recommendation Impact Across KPIs

| KPI | Impact | Calculated? |
| --- | --- | --- |
| **Reliability:** | No direct reliability impact identified | ❌ |
| **Security Compliance:** | No direct security impact identified | ❌ |
| **Economic:** | No direct economic impact identified | ❌ |
| **User Experience:** | No direct user experience impact identified | ❌ |
| **Environment:** | Reduction in carbon footprint through optimized resource utilization | ✅ |

## Score Calculation

### 1\. Data Ingestion

-   VM Instance Name
-   Current VM Size
-   Current Resource Utilization
-   Current Carbon Usage

### 2\. Data Enrichment

-   Mapping to recommended VM sizes
-   Carbon usage calculation for current and recommended sizes
-   Resource utilization patterns

### 3\. Health Score

-   Calculate the Environment score based on the formula: (Carbon Usage of current VM - Carbon Usage of new recommendation) / Total Carbon Usage of all assets
