To automatically handle changing capacity needs based on your current player demand, Amazon GameLift autoscales the number of instances up and down throughout the day. However, based on the variability from player traffic, most games don’t need peak capacity 24/7. So Spot instances give us a 42% savings over colocation. Running 2,500 instances 24 hours a day for an entire month (assuming a 30 day month) comes to $229,000 per month for On-Demand instances, but only $72,000 per month for Spot instances. Using our rule of thumb, we arrive at a Spot instance price of $0.04. The On-Demand price for a c4.large instance in the US East (N. While Spot prices fluctuate throughout the day, a good rule of thumb is that Amazon GameLift Spot instances running Linux are on average 70% less expensive than the same On-Demand instances. Now we’ll calculate the cost savings from using Amazon GameLift Spot instances. Next, we chose a comparable configuration with Amazon GameLift: a c4.large instance meets the 2 CPU cores with 3 GB of memory requirement. These inputs result in a 3-year total compute cost of about $4.5 million, or roughly $125,000 per month. At peak demand, we assumed we needed 2,500 instances running. Virginia) using Linux as our operating system and 2 CPU cores and 3 GB of memory for our servers. We start with the AWS Total Cost of Ownership (TCO) calculator to estimate the cost of running game servers in a colocation environment.įor this example, we calculated costs in the US East region (N. Watch our video to learn more or see a sample cost comparison below.
Compared to running servers in a colocation environment, Amazon GameLift with Spot Instances and Autoscaling can save you up to 70% on compute costs.
