AWS SimSpace Weaver Documentation

AWS SimSpace Weaver is designed to handle deploying and managing your simulation infrastructure. You can scale your spatial simulations across multiple Amazon Elastic Compute Cloud (Amazon EC2) instances while SimSpace Weaver manages provisioning, networking, and deprovisioning infrastructure for you.

SimSpace Weaver is a flexible service that gives you the opportunity to scale up your own simulation engines. Integrate with the SimSpace Weaver app SDK to create AWS SimSpace Weaver applications (or simply apps). Then, upload your apps to Amazon Simple Storage Service (Amazon S3) and use them as part of your simulation. Apps can take many different forms and perform various read and write functions based on your simulation code. Within a single simulation, these apps run distributed across your chosen quantity of Amazon EC2 instances while SimSpace Weaver manages the communication and simulation state between them. You can build simulation Apps that manage object pathfinding and create specialized apps that send simulation data down to a client for visualization purposes.

SimSpace Weaver is designed to divide the simulation world into discrete areas called spatial partitions. SimSpace Weaver is built to partition your simulation world according to your predefined configuration. Each spatial area is managed by a SimSpace Weaver app that is responsible for the simulation logic and behavior of all entities within that area. 

SimSpace Weaver is designed to maintain the global state of all simulated entities, meaning that every entity can be aware of each other's spatial presence and state. SimSpace Weaver is also designed to manage the memory and replication of entity data between servers, allowing entities to seamlessly cross boundaries between different simulation areas.

SimSpace Weaver provides the ability for applications to read simulation data from other areas of the simulation using the subscription system. This means simulation objects can account for events happening in neighboring partitions or interact with other objects along partition boundaries. Use subscriptions to read data out of the simulation for visualization and interactivity.

The SimSpace Weaver app SDK contains Messaging APIs that you can use to send and receive messages between applications in a simulation. Subscriptions offer a pull method to read simulation events; messaging offers a push method to transmit data in the simulation. SimSpace Weaver messages contain the sender in the message header so message recipients can reply. You can use messages to forward information that an application receives from an external client to other applications in the simulation.

You can run simulations with different sets of logic and behaviors in the same simulated environment. Each domain can have its own allocated compute resources, and entities can interact and transfer across domains. 

Snapshots allow you to save the state of your simulation entities at a point in time. SimSpace Weaver is designed to upload and store Snapshot files in Amazon S3. You can use your Snapshot files to launch new simulations with the Start Simulation API. 

Run simulation code by using your own local hardware. AWS SimSpace Weaver Local uses the same APIs as the cloud service, so you can transition to the cloud for full-scale production. AWS SimSpace Weaver Local is available for both Windows and Linux.

SimSpace Weaver offers built-in integrations with Unreal Engine 5 and Unity LTS Release 2021.3.7f1.

You can utilize your own container images to run your simulation applications instead of AWS SimSpace Weaver’s stock Amazon Linux (AL2) container. Create your own AL2 based container images with any dependencies required by your simulation applications and upload the images to Amazon Elastic Container Registry (Amazon ECR).
