Generating estimates for Windows Servers and SQL Servers on EC2 Dedicated Hosts

You can use the workload calculator in AWS Pricing Calculator as a guide to the AWS tenancy qualifications for Microsoft Windows Server and SQL Server on Amazon Elastic Compute Cloud (Amazon EC2). You can use the workload calculator to estimate AWS cost using minimal information or generate a rough estimate.

For options for using Microsoft software licenses on the AWS Cloud, see Microsoft Licensing on AWS.

Licensing and tenancy recommendations

You can determine your AWS licensing and tenancy options for your workload through your choices for Windows Server and SQL Server licensing inputs. The licensing options include AWS provided licenses with License Included (LI) offerings. They also include your existing licenses with Bring Your Own License (BYOL) offerings for optimal cost savings. You can identify which is the most suitable cloud tenancy.

The following table shows the AWS licensing and tenancy scenarios supported by AWS Pricing Calculator.

Windows Server	SQL Server	AWS tenancy
LI	LI	Shared tenancy
LI	BYOL	Shared tenancy or Dedicated Hosts
BYOL	BYOL	Dedicated Hosts
BYOL	LI	Not supported

Machine specifications

Based on your choice of machine specification, we recommend that you select the Amazon EC2 instance that AWS Pricing Calculator uses to generate an estimate for your cost. You can also select another instance or instances of your choosing or add multiple machine specifications for a workload.

This section defines the terms that are mentioned in the Configure machine specifications section.

Machine description

A description for the machine. This is generally a hostname identifier. If you don't know the hostname identifier, specify unique software components that run on this machine—for example, WebApp DB1 or Webserver 1.

Operating system

Depending on your tenancy qualification, you can choose an operating system with a licensing option. The default value is Windows.

SQL Server edition

Depending on your tenancy qualification, you can choose a SQL Server with licensing option. The default value is SQL Standard.

vCPU, Memory

Enter the number of vCPUs and memory inputs for your machine configuration. For example, 4vCPU and 8GB of memory.

Quantity

The default value is 1. This is the minimum number that's required.

Review dedicated hosts

The Review dedicated hosts table shows your recommended dedicated hosts instance family based on your inputs. You can see details such as host family and description, instances, license count, and used capacity (virtual cores). List count shows the license needed for a specific dedicated host.

Choose the instances to see the machines that are optimally packed within a single dedicated host.

By choosing Download CSV, you can download the dedicated host, instance, and license information.

Pricing strategy

Your choices in the pricing strategy section determine the pricing strategy that AWS Pricing Calculator uses to generate your estimate.

Pricing model

The pricing model determines whether you're searching for a pay-as-you-use instance or an instance that you can reserve in advance. For Reserved Instance (RI) payment options, see payment options.

The default value is Standard Reserved Instances. This is because it's the most common Amazon EC2 purchase, and it offers the flexibility with highest discount for most use cases.

Reservation term

When you reserve an RI, you purchase a reservation for the period of your contract. For your contract term, choose 1 year or 3 years. By default, a term is 1 year. This is to save costs.

Payment options

Payment options determine when you pay for your RI reservation.

Full upfront - You pay for the entire reservation upfront, resulting in a single payment but no monthly, recurring payments. This option provides the best discount.

Partial upfront - You pay for a smaller, partial upfront fee along with monthly payments.

No upfront - You only pay on a monthly basis.

The default value is No upfront. It gives you the least costly start-up price.

Cost details

The cost details section provides details for your workload.

EC2 Instance costs

A summary of the itemized breakdown for an EC2 instance. Pause on each row to show additional information, such as instance type, operating system, SQL version, vCPU, memory, quantity, optimize CPU, and SQL passive node.

Amazon EBS costs
