Microsoft Azure Fundamentals (AZ-900)Describe Azure architecture and servicesEasy
A small startup is deploying its first application to Azure. They need a service that provides a dedicated, isolated environment for their virtual machines to ensure maximum security and performance, and they want to pay for the underlying hardware resources whether or not their VMs are running. Which Azure service should they choose?
- AAzure App Service
- BAzure Container Instances (ACI)
- CAzure Dedicated Host
- DAzure Virtual Machines (VMs)
Show answer & explanationAnswer & explanation
Correct answer: C. Azure Dedicated Host
Azure Dedicated Host provides single-tenant physical servers, offering the highest level of isolation and control over the server environment. This meets the requirement for a dedicated, isolated environment and the pricing model aligns with paying for the underlying hardware.
Why the other options are wrong
- A. Azure App Service is a platform-as-a-service offering, not designed for dedicated VM isolation.
- B. Azure Container Instances are for containers, not virtual machines, and do not offer dedicated physical server isolation.
- D. Azure Virtual Machines typically run on shared hardware, which does not provide dedicated isolation.
Azure Dedicated Host
Azure Dedicated Host is a service that provides physical servers that are dedicated to a single Azure subscription.
- Offers hardware isolation at the physical server level.
- Provides control over server maintenance events.
- Billing is for the host, not per VM, and is consistent regardless of VM usage.
Memory trick: Dedicated hosts offer the ultimate 'private island' for your VMs, like a secret agent's hideout.
