- You can realize even bigger cost reductions at the same time as improvements to fleet stability relative to regular Spot usage by using [Spot fleet](http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/spot-fleet.html) to bid on instances across instance types, availability zones, and (through multiple Spot Fleet Requests) regions. - You can realize even bigger cost reductions at the same time as improvements to fleet stability relative to regular Spot usage by using [Spot fleet](http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/spot-fleet.html) to bid on instances across instance types, availability zones, and (through multiple Spot Fleet Requests) regions.
- Spot fleet targets maintaining a specified (and weighted-by-instance-type) total capacity across a cluster of servers. If the Spot price of one instance type and availability zone combination rises above the weighted bid, it will rotate running instances out and bring up new ones of another type and location up in order to maintain the target capacity without going over target cluster cost. - Spot fleet targets maintaining a specified (and weighted-by-instance-type) total capacity across a cluster of servers.

- Profile your application to figure out its runtime characteristics. That would help give an understanding of the minimum cpu, memory, disk required. Having this information is critical before you try to optimize spot costs. - Profile your application to figure out its runtime characteristics. That would help give an understanding of the minimum cpu, memory, disk required. Having this information is critical before you try to optimize spot costs.
- Once you know the minimum application requirements, instead of resorting to fixed instance types, you can bid across a variety of instance types (that gives you higher chances of getting a spot instance to run your application).E.g., If you know that 4 cpu cores are enough for your job, you can choose any instance type that is equal or above 4 cores and that has the least Spot price based on history. This helps you bid for instances with greater discount (less demand at that point). - Once you know the minimum application requirements, instead of resorting to fixed instance types, you can bid across a variety of instance types (that gives you higher chances of getting a spot instance to run your application).E.g., If you know that 4 cpu cores are enough for your job, you can choose any instance type that is equal or above 4 cores and that has the least Spot price based on history.

- Spot Instance prices fluctuate depending on instance types, time of day, region and availability zone. The AWS CLI tools and API allow you to describe Spot price metadata given time, instance type, and region/AZ. - Spot Instance prices fluctuate depending on instance types, time of day, region and availability zone.
