When you chose your Load Agent deployment options, we do a real time call to AWS to find the current pricing of Spot Instances. We up this a bit to create an estimated bid price.

However, if you are deploying a large number of spot instances of one type in one region, you can actually bid up the price of what is available. In this example, the current bid price of an m3.2XLarge is $0.25 per hour and we adjust that up to $0.27. But AWS will see the large number and not allocate all 25 servers requested. This results in an error:

There are several strategies to avoid this:

• Up your bid price
• Mix different instance sizes
• Run from multiple Regions
• Run using on-demand instances instead of spot instances

RedLine gives you the ability to easily add multiple “packs” of spot instances.
