Question
A big data analytics company is moving its IT infrastructure from an on-premises data center to AWS Cloud. The company has some server-bound software licenses that it wants to use on AWS. As a Cloud Practitioner, which of the following EC2 instance types would you recommend to the company?Question 5Answera.On-Demand Instanceb.Reserved Instance (RI)c.Dedicated Instanced.Dedicated Host
Solution
The best option for the company would be d. Dedicated Host.
AWS Dedicated Hosts are physical servers with EC2 instance capacity fully dedicated to your use. This allows you to use your existing server-bound software licenses, including Windows Server, SQL Server, and SUSE Linux Enterprise Server (subject to your license terms), and can help you reduce costs.
Here's a step-by-step explanation:
-
On-Demand Instance: This option allows you to pay for compute capacity by the hour with no long-term commitments. This wouldn't be the best choice for the company as it doesn't specifically cater to the need of using server-bound software licenses.
-
Reserved Instance (RI): This option provides you with a significant discount (up to 75%) compared to On-Demand instance pricing. However, like On-Demand Instances, it doesn't cater to the need of using server-bound software licenses.
-
Dedicated Instance: This is an instance that is physically isolated at the host hardware level and launched within a VPC. However, it doesn't allow you to use your existing server-bound software licenses.
-
Dedicated Host: This is a physical server with EC2 instance capacity fully dedicated for your use. AWS Dedicated Hosts allow you to use your eligible software licenses from vendors such as Microsoft and Oracle on Amazon EC2, so you get the flexibility and cost effectiveness of using your own licenses. This would be the best choice for the company as it allows them to use their server-bound software licenses.
