Use AWS SimSpace Weaver to scale spatial simulations across multiple instances without worrying about the underlying compute, networking, or data replication. You pay an hourly rate (minimum 60 seconds) for each Amazon Elastic Compute Cloud (Amazon EC2) instance used by your simulation, with no upfront commitments. The billing period begins when you start your simulations and ends when they are stopped or terminated. For details, see Pricing.
The executable code (or binaries) that you create and run as part of your simulation is called applications (or apps). The number of concurrently running apps that each SimSpace Weaver instance can support is specified in the following pricing tables. Each app is assigned 2 vCPU and 1 GB of memory by default. To provide more vCPU per application, you can adjust configurations. To learn more, refer to the AWS SimSpace Weaver documentation.
Simulation Compute Pricing
Pricing example 1: Simulation on a single instance
Suppose that you’re building a smart city simulation. You use only a single instance for your testing. The bill at the end of the month (22 days, assuming no weekend usage), using AWS SimSpace Weaver in US East (Ohio) would be calculated as follows.
Monthly simulation charges
Assume that you test your simulation code for 3 hours a day over the course of a month (22 days). You keep all your testing to one instance and pay the single instance price of $6.08/hour for that instance. Over the course of the month, you use 66 hours of compute. You would incur charges as detailed in the following table:
Usage type |
Number of instances used per simulation |
Simulation runtime per day in hours |
Days per month |
Compute hours |
Price |
Charge for the month |
sim.c5.24xlarge |
1 |
3 |
22 |
Instance hours = 1 * 3 * 22 = |
$6.08 per hour per instance |
66 hours * $6.08/hour = $401.28 |
For the month, your bill will be $401.28 for the total number of compute hours used.
Pricing example 2: Simulation across 10 instances
Now you’re ready for full-scale production for your smart city. Continuing from Pricing example 1, you increase your scale to 10 instances. The bill at the end of the month (22 days, assuming no weekend usage), using AWS SimSpace Weaver in US East (Ohio) would be calculated as follows.
Monthly simulation charges
Assume that you run your 10-instance simulation continuously during business hours for 8 hours a day. Scaling across 10 instances, you still pay $6.08/hour for each of the 10 instances. Over the course of the month, you use 1,760 hours of compute. You would incur charges as detailed in the following table:
Usage type |
Number of instances used per simulation |
Simulation runtime per day in hours |
Days per month |
Compute hours |
Price |
Charge for the month |
sim.c5.24xlarge |
10 |
8 |
22 |
Instance hours = 10 * 8 * 22 = 1,760 hours |
$6.08 per hour per instance |
1,760 hours * $6.08/hour = $10,700.80 |
For the month, your bill will be $10,700.80 for the total number of compute hours used.
Snapshots
Snapshots are a feature you can use to save the current state of a live simulation. When a snapshot is taken, it is placed into an Amazon S3 bucket of your choosing. There is no cost to take a snapshot or start a new simulation from a snapshot. You simply pay for the Amazon S3 charges associated with storing your snapshot objects. To learn more, visit the Amazon S3 Pricing Page.
