Final Answer:
For a small company with limited resources and a need to migrate their on-premises storage server to the cloud, an appropriate Azure solution would be Azure Blob Storage (Option 2).
Step-by-step explanation:
Azure Virtual Machines (Option 1): While Azure VMs could host applications or servers, they might be overkill for a small company with limited capital, as they require more management and incur ongoing compute costs.
Azure Blob Storage (Option 2): This solution allows cost-effective and scalable storage in the cloud. It's suitable for storing unstructured data like documents, images, and videos. The pay-as-you-go pricing model ensures cost-effectiveness for a small company.
Azure SQL Database (Option 3): This is more appropriate for database-centric applications and may have higher associated costs, making it less suitable for a small company with minimal capital.
Azure App Service (Option 4): This is geared towards hosting web applications, which might not align with the company's primary goal of migrating storage.
Option 2 (Azure Blob Storage) is the most fitting solution.
