Tutorial: Amazon EC2 Spot Instances

Overview

Spot Instances allow you to bid on unused Amazon Elastic Compute Cloud (Amazon EC2) capacity and

run the acquired instances for as long as your bid exceeds the current Spot Price. Amazon EC2 changes

the Spot Price periodically based on supply and demand, and customers whose bids meet or exceed it

gain access to the available Spot Instances. Like On-Demand Instances and Reserved Instances, Spot

Instances provide you another option for obtaining more compute capacity.

Spot Instances can significantly lower your Amazon EC2 costs for batch processing, scientific research,

image processing, video encoding, data and web crawling, financial analysis, and testing. Additionally,

Spot Instances give you access to large amounts of additional capacity in situations where the need for

that capacity is not urgent.

To use Spot Instances, place a Spot Instance request specifying the maximum price you are willing to

pay per instance hour; this is your bid. If your 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 bid (whichever is sooner).

It's important to note two points:

• You will often pay less per hour than your bid. Amazon EC2 adjusts the Spot Price periodically as

requests come in and available supply changes. Everyone pays the same Spot Price for that period

regardless of whether their bid was higher. Therefore, you might pay less than your bid, but you will

never pay more than your bid.

• If you're running Spot Instances and your bid no longer meets or exceeds the current Spot Price, your

instances will be terminated. This means that you will want to make sure that your workloads and

applications are flexible enough to take advantage of this opportunistic capacity.

Spot Instances perform exactly like other Amazon EC2 instances while running, and like other Amazon

EC2 instances, Spot Instances can be terminated when you no longer need them. If you terminate your

instance, you pay for any partial hour used (as you would for On-Demand or Reserved Instances).

However, if the Spot Price goes above your bid and your instance is terminated by Amazon EC2, you

will not be charged for any partial hour of usage.
