A company needs to migrate its website from on premises to the AWS Cloud. The website must be hosted on hardware that is not shared with other companies. The company wants to use its existing per-socket, per-core software licenses.
Which Amazon EC2 instance purchasing option will meet these requirements?
A
Dedicated Instance
B
Reserved Instance
C
Dedicated Host
D
On-Demand Instance
Explanation:
Dedicated Host is the correct answer because:
Hardware Isolation: Dedicated Host provides physical server isolation, ensuring the company's website runs on hardware that is not shared with other companies
License Flexibility: Dedicated Host allows companies to use their existing per-socket, per-core software licenses, which is specifically mentioned in the requirements
Compliance: Meets the requirement for dedicated hardware while maintaining existing licensing arrangements
Why other options are incorrect:
Dedicated Instance: While this provides instance-level isolation, it doesn't guarantee the same level of hardware control for licensing purposes
Reserved Instance: This is a billing option that provides cost savings but doesn't address hardware isolation or licensing requirements
On-Demand Instance: This is a pay-as-you-go pricing model with no hardware isolation or licensing benefits
Dedicated Host is specifically designed for customers who need to meet compliance requirements, use existing software licenses, or have specific hardware isolation needs.
