Amazon EC2 Dedicated Instances

Dedicated Instances are Amazon EC2 instances launched within your Amazon Virtual Private Cloud (Amazon VPC) that run hardware dedicated to a single customer. Dedicated Instances let you take full advantage of the benefits of Amazon VPC and the AWS cloud – on-demand elastic provisioning, pay only for what you use, and a private, isolated virtual network, all while ensuring that your Amazon EC2 compute instances will be isolated at the hardware level.

You can easily create a VPC that contains dedicated instances only, providing physical isolation for all Amazon EC2 compute instances launched into that VPC, or you can choose to mix both dedicated instances and non-dedicated instances within the same VPC based on application-specific requirements. Click here for additional instructions on launching Dedicated Instances.

Pricing

Pay only for what you use with no long-term commitments. Dedicated Instance pricing has two components: (1) an hourly per instance usage fee and (2) a dedicated per region fee (note that you pay this once per hour regardless of how many Dedicated Instances you're running).

Dedicated Per Region Fee

• $10 per hour - An additional fee is charged once per hour in which at least one Dedicated Instance of any type is running in a Region.

Dedicated On-Demand Instances

On-Demand Instances let you pay for compute capacity by the hour with no long-term commitments.

Pricing is per instance-hour consumed for each instance type. Partial instance-hours consumed are billed as full hours.

Dedicated Reserved Instances

Dedicated Reserved Instances give you the option to make a low, one-time payment for each instance you want to reserve and in turn receive a significant discount on the hourly charge for that instance. Click here to learn more about Reserved Instances.

Light Utilization Reserved Instances

Medium Utilization Reserved Instances

Heavy Utilization Reserved Instances

Reserved Instances can be purchased for 1 or 3 year terms, and the one-time fee per instance is non-refundable. Light and Medium Utilization Reserved Instances also are billed by the instance-hour for the time that instances are in a running state; if you do not run the instance in an hour, there is zero usage charge. Partial instance-hours consumed are billed as full hours. Heavy Utilization Reserved Instances are billed for every hour during the entire Reserved Instance term (which means you’re charged the hourly fee regardless of whether any usage has occurred during an hour).

Reserved Instance Volume Discounts

When you have purchased a sufficient number of Reserved Instances in an AWS Region, you will automatically receive discounts on your upfront fees and usage fees for future purchases of Reserved Instances in that AWS Region. Reserved Instance Tiers are determined based on the total list price (non-discounted price) of upfront fees for the active Reserved Instances you have per AWS Region. A complete list of the Reserved Instance Tiers is shown below:

For example, as soon as you have active Reserved Instances with total list price of upfront fees totaling more than $250,000 in a single AWS Region, you will automatically receive a 10% discount on both upfront and hourly fees for all future Reserved Instance purchases in that AWS Region, and those discounts will continue to apply to new Reserved Instances as long as you continue to qualify for the discount tier.

To illustrate, let's assume you currently have $200,000 worth of active Reserved Instances in us-east-1. You purchase 75 Reserved Instances at $1000 each. That's a total of $75,000. The first $50,000 of this purchase would be discounted at 0 percent. The remaining $25,000 of your purchase will be discounted by 10 percent, so you will only be charged $22,500 for it, and you will pay discounted hourly fees on those Reserved Instances.

AWS GovCloud Region

AWS GovCloud is an AWS Region designed to allow U.S. government agencies and contractors to move more sensitive workloads into the cloud by addressing their specific regulatory and compliance requirements.

Getting Started

• Open and log into the AWS Management Console
• Create an Amazon VPC if you do not already have one on the Amazon VPC tab
• Click on Launch Instance from the EC2 Dashboard
• Select Launch Instances Into Your Virtual Private Cloud
• Modify the instance tenancy from Default to Dedicated in the Request Instances Wizard
• Start using your instance with the knowledge it will not share hardware with instances launched by other customers

The AWS Management Console is an easy tool to start and manage your instances. If you are looking for more details on launching an instance, a quick video tutorial on how to use Amazon EC2 with the AWS Management Console can be found here .
