|AMAZON WEB SERVICES ANNOUNCES SPOT INSTANCES FOR AMAZON EC2|
Allows customers to bid on unused capacity, enabling lower costs and access to significant short-term capacity for those with flexibility in when their applications can run
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,”
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
“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
“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
About Amazon EC2
