From your Spinup space create a new server as usual (in this case I’ve picked CentOS 8 Windows 2022 but Spot should work with all OS flavors). You should see a Spot checkbox in the upper-right corner - clicking that will display the available spot sizes.

Selecting a size (in this case spot-micro) will show the specific instance types for that size. The Spot service will try to allocate an available instance in the listed order - so it will first try to create a t3a.micro - if one is not available it will try t3.micro, and lastly t2.micro.
...
As mentioned before, we cannot provide a cost estimate, but the cost will never exceed the cost of a regular instance (so in this case you can use the cost of a t3.micro as an estimate for worst-case scenario). In 99.9% of cases, the actual price for spot will be much lower. You can see details about the incurred costs and savings once the server is running.

From the server view you can see more information about the costs incurred by your Spot server and the savings compared to paying list price. In the Size field you can see that we got a t3a.micro instance. Also note that you are not able to Shut down, Resize, or Create image from Spot servers.
