8/5     VPS is a LOT cheaper than EC2 by at least 5X and sometimes
        10X. Why is EC2 so popular when the price is not even
        \_ One month of standard with 600GB of bandwidth is $39/mo
           for VPS. For a year that would be $428. That is about
           the same price as an EC2 medium instance for a year.
           Where do you get the 5X from?
        \_ VPS is not terribly elastic, and hasn't got a rich API w/
           programmable network and storage services?

AWS's Free Usage Tier, new AWS customers can get started with Amazon EC2 for free. Upon sign-up, new AWS customers receive the following EC2 services each month for one year: * 750 hours of EC2 running Linux/Unix Micro instance usage * 750 hours of EC2 running Microsoft Windows Server Micro instance usage * 750 hours of Elastic Load Balancing plus 15 GB data processing * 30 GB of Amazon EBS Standard volume storage plus 2 million IOs and 1 GB snapshot storage * 15 GB of bandwidth out aggregated across all AWS services * 1 GB of Regional Data Transfer On-Demand Instances On-Demand Instances let you pay for compute capacity by the hour with no long-term commitments. This frees you from the costs and complexities of planning, purchasing, and maintaining hardware and transforms what are commonly large fixed costs into much smaller variable costs. The pricing below includes the cost to run private and public AMIs on the specified operating system ("Windows Usage" prices apply to Windows Server 2003 R2, 2008 and 2008 R2). Pricing is per instance-hour consumed for each instance, from the time an instance is launched until it is terminated. Each partial instance-hour consumed will be billed as a full hour. Reserved Instances 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. There are three Reserved Instance types (Light, Medium, and Heavy Utilization Reserved Instances) that enable you to balance the amount you pay upfront with your effective hourly price. The following tables display the Reserved Instance Prices. Windows Linux Light Utilization Reserved Instances Sorry, pricing information requires JavaScript. Windows Light Utilization Reserved Instances Sorry, pricing information requires JavaScript. Windows Linux Medium Utilization Reserved Instances Sorry, pricing information requires JavaScript. Windows Medium Utilization Reserved Instances Sorry, pricing information requires JavaScript. Windows Linux Heavy Utilization Reserved Instances Sorry, pricing information requires JavaScript. Windows Heavy Utilization Reserved Instances Sorry, pricing information requires JavaScript. 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). If Microsoft or Red Hat chooses to increase the license fees that it charges for Windows or Red Hat Enterprise Linux, we may correspondingly increase the per-hour usage rate for previously purchased Reserved Instances with Windows or Red Hat Enterprise Linux. The initial one-time payment for a Reserved Instance will be unaffected in this situation. Any such changes for Windows would be made between Dec 1 - Jan 31, and with at least 30 days' notice. Any such changes for Red Hat Enterprise Linux would be made at least 30 days' notice. If the per-hour usage rate does increase, you may continue to use your Reserved Instance with Windows or Red Hat Enterprise Linux with the new per-hour usage rate, convert your Reserved Instance with Windows or Red Hat Enterprise Linux to a Reserved Instance with Linux/UNIX, or request a pro rata refund of the upfront fee you paid for the Reserved Instance with Windows or Red Hat Enterprise Linux. Reserved Instances are available for Linux/UNIX, Windows, Red Hat Enterprise Linux, and SUSE Linux Enterprise operating systems. You can also optionally reserve instances in Amazon VPC at the same prices as shown above. 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. Contact Us 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. 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. Spot Instances Spot Instances enable you to bid for unused Amazon EC2 capacity. Instances are charged the Spot Price, which is set by Amazon EC2 and fluctuates periodically depending on the supply of and demand for Spot Instance capacity. To use Spot Instances, you place a Spot Instance request, specifying the instance type, the Availability Zone desired, the number of Spot Instances you want to run, and the maximum price you are willing to pay per instance hour. To determine how that maximum price compares to past Spot Prices, the Spot Price history is available via the Amazon EC2 API and the AWS Management Console. If your maximum price bid exceeds the current Spot Price, your request is fulfilled and your instances will run until either you choose to terminate them or the Spot Price increases above your maximum price (whichever is sooner). Log in to the AWS Management Console, then click the "Amazon EC2" tab. Data Transfer** Internet Data Transfer The pricing below is based on data transferred "in" and "out" of Amazon EC2. CAPTION: There is no Data Transfer charge between Amazon EC2 and other Amazon Web Services within the same region (ie between Amazon EC2 US West and Amazon S3 in US West). Data transferred between Amazon EC2 instances located in different Availability Zones in the same Region will be charged Regional Data Transfer. Data transferred between AWS services in different regions will be charged as Internet Data Transfer on both sides of the transfer. Usage for other Amazon Web Services is billed separately from Amazon EC2. Regional Data Transfer * - all data transferred between instances in different Availability Zones in the same region. Public and Elastic IP and Elastic Load Balancing Data Transfer * - If you choose to communicate using your Public or Elastic IP address or Elastic Load Balancer inside of the Amazon EC2 network, you'll pay Regional Data Transfer rates even if the instances are in the same Availability Zone. EBS-Optimized Instances EBS-Optimized instances enable Amazon EC2 instances to fully utilize the IOPS provisioned on an EBS volume. EBS-Optimized instances deliver dedicated throughput between Amazon EC2 and Amazon EBS, with options between 500 Mbps and 1000 Mbps depending on the instance type used. The hourly price for EBS-Optimized instances is in addition to the hourly usage fee for supported instance types. Amazon Elastic Block Store Sorry, pricing information requires JavaScript. Provisioned IOPS is charged by the amount you provision in IOPS (input/output operations per second) X the percentage of days you provision for the month. Amazon EBS currently supports up to 1000 IOPS per Provisioned IOPS volume, with higher limits coming soon. For a given allocation of resources, the IOPS rate you get from your Provisioned IOPS volume depends on the I/O size of your applications' reads and writes. Provisioned IOPS volumes process your applications' reads and writes in I/O sizes of 16KB or ...
