CloudDeployer

CloudDeployer puts the AWS side of your multiplayer game into the Unreal Editor. Package your Linux server, build and push its Docker image, deploy the infrastructure and watch it come up - without switching to the AWS console or a terminal.

Three Alpha XP CloudFormation templates are included: an ECS Fargate dedicated-server service (cluster, task definition, service, security group with the UDP and TCP game port, log group, roles), an EC2 Auto Scaling game-server fleet (launch template that installs and starts your server, Auto Scaling group, security group, Session Manager access) and an ECR repository with a lifecycle policy. Deploy them as they are or use them as a starting point for your own.

The CloudDeployer tab (Window > Tools > Alpha XP > CloudDeployer) lists the stacks of the region with their status, validates a template and turns its parameters into an editable list, deploys it (create or update), follows the stack's event log live, shows its outputs and deletes stacks after a confirmation.

For automation, 90 Blueprint nodes work in Editor Utility Blueprints and Editor Utility Widgets. Deploy Stack creates or updates a stack and waits for the result while streaming every event; Wait For Stack follows any operation. Change sets preview updates, Estimate Template Cost links to the cost calculator. The ECR and Docker nodes create repositories and lifecycle policies, log Docker in to ECR without ever putting the password on a command line, build and push the image with live output, and generate a Dockerfile for a packaged Linux server. The ECS nodes register Fargate task definitions, create, scale and update services, run one server per match with Run Task and return the address players connect to with Get Task Public IP. EC2 and Auto Scaling nodes manage instances, security group ingress, key pairs, VPCs and subnets, and the size and processes of fleets.

Credentials come from your AWS CLI configuration - named profiles, SSO, credential_process and assume-role - or from static keys or a Cognito identity pool, and Get Caller Identity checks them in one click. Settings are stored per user, never in the project's Config folder. Every destructive node requires an explicit Confirm input. All requests run on background threads with automatic retries, so the editor never freezes.

CloudDeployer is part of the Alpha XP AWS collection for Unreal Engine 4.27 and 5.8. It is an editor-only plugin for the Win64 editor, includes the AWS SDK for C++ prebuilt, and ships with styled HTML documentation.

Blueprint & C++ API

Every call is reachable from more than one place — pick the entry point that fits your project:

Callable runs when executed · Pure no exec pin, returns a value · LatentAsync finishes later and fires its outputs

Project settings

Configure once under Project Settings › Plugins › CloudDeployer — values are saved to the project's config .ini, so they travel with the project and your build.

Options & enums

Compatibility

One ready-made build per engine version is included in the download — copy the one that matches your project.
