| Security | GuardDuty, Inspector, Macie | Azure Security Center, Defender for Cloud |
| Cost Management | AWS Cost Explorer, Budgets | Azure Cost Management |
In the context of Scale Sets, here is a comparison between AWS and Azure:
| Feature | AWS | Azure |
|---|---|---|
| Service Name | Auto Scaling Groups | Virtual Machine Scale Sets (VMSS) |
| Purpose | Automatically adjusts EC2 instances based on demand. | Automatically scales virtual machines in response to demand. |
| Scaling Options | Horizontal (add/remove instances). | Horizontal (add/remove VMs). |
| Integration | Works with EC2, ELB, and Auto Scaling Policies. | Integrates with Azure Load Balancer and Application Gateway. |
| Configuration | Launch templates/configurations. | VMSS templates with configurations for OS and settings. |
| Flexibility | Supports EC2 Spot Instances and On-Demand. | Supports both VM Spot and On-Demand instances. |
| Orchestration | Managed by EC2 Auto Scaling. | Fully integrated into Azure Resource Manager. |
