Amazon Web Services Announces Spot Instances For Amazon EC2

12/14/2009

Amazon Web Services LLC, an Amazon.com company, today announced Spot Instances, a new option for purchasing and consuming Amazon EC2 compute resources. With Spot Instances, customers bid on unused Amazon EC2 capacity and run those instances for as long as their bid exceeds the current Spot Price.



ebizQ received the following:

The Spot Price changes periodically based on supply and demand, and customers whose bids exceed it gain access to the available Spot Instances. Spot Instances are complementary to On-Demand Instances and Reserved Instances, providing another way to obtain Amazon EC2 compute capacity. To get started using Amazon EC2 Spot Instances, visit http://aws.amazon.com.

Spot Instances are well-suited for applications that can have flexible start and stop times such as image and video conversion and rendering, data processing, financial modeling and analysis, web crawling and load testing. By being flexible on when their instances run, coupled with the ability to bid what they’re willing to pay for capacity, customers can significantly lower their Amazon EC2 costs. In addition, Spot Instances can provide access to large amounts of additional capacity for applications with urgent needs. When these needs arise, users can specify a higher maximum bid, which will raise the priority of a request for capacity.

To use Spot Instances, customers place a Spot Instance request, specifying the instance family, size and the region they desire as well as the number of Spot Instances they want to run and the maximum price they’re willing to pay per instance. If a customer’s maximum price exceeds the current Spot Price, the customer’s instances will run until they choose to terminate the instances or their maximum bid falls below the Spot Price (whichever is sooner). Like other Amazon EC2 instances, Spot Instances can be terminated when they are no longer needed. If the Spot Price goes above a user’s maximum bid and the instance is terminated by Amazon EC2, the user will not be charged for any partial hour of usage.

"As customers continued to expand their use of AWS, they started asking if additional pools of capacity were available, even if only for a few hours at a time. Some customers were looking to reduce costs in exchange for being flexible as to when they run their application; others told us they were willing to pay more when they had urgent, high volume needs,” said Peter De Santis, General Manger of Amazon EC2. “Because of the dynamic nature of supply and demand in the Amazon EC2 environment, we developed Spot Instances to let customers take advantage of our unused capacity while specifying a price they are willing to pay."

Spot Instances run the same software images and come in the same compute instance families and sizes as both On-Demand and Reserved Instances, so users can easily move between the purchasing options that best meet the needs of their application. On-Demand Instances allow you to pay a fixed rate by the hour with no commitment; Reserved Instances provide capacity at a lower hourly rate in exchange for a low, one-time, upfront payment; and Spot Instances provide the ability to bid whatever price you want on unused capacity for applications with flexible start and end times. Together, these three different purchasing models give users the flexibility to optimize costs.

"Spot Instances and the Condor scheduler will enable a 'no compute cycle left behind' policy for running scientific and financial calculations on Amazon EC2," said Jason Stowe, CEO of Cycle Computing. "Our CycleCloud service provides secure, elastic compute clusters on Amazon EC2, helping our customers, including Eli Lilly, Varian Inc. and Pfizer, run molecular modeling, next-generation sequencing and risk-analysis calculations. With Spot Instances, CycleCloud can execute calculations when the price is right, resulting in real cost management for our clients."

“Clarity Solutions provides advanced investment platforms and advisory services to financial institutions. We’re using On-Demand instances to provide our clients with deep insight into opportunities and risks in structured finance and credit derivatives markets,” said Adam Kirby, CEO of Clarity Solutions. “We’re excited about Spot Instances because they enable our clients to lower costs on batch processing and provide access to a pool of resources for time-critical workloads. We see this as just another example of how AWS is pioneering the future of cloud computing.”

“Spot Instances enable cost-efficient computing across the spectrum of simulations run by our pharmaceutical and life sciences customers. We can now run jobs that had previously been set aside as too expensive to process,” said Chris Dagdigian, Founder and Director of Technology at Bioteam, Inc. “With Spot Instances, those jobs are coming off the shelf and further contributing to the product development process.”
