AWS AWSCloudFormation documentation change
Summary
Rewrote stream group documentation with detailed capacity management explanations and billing models.
Security assessment
The changes focus on resource allocation and cost management without security implications. No security controls or vulnerabilities are mentioned.

Please update your bo -The `AWS::GameLiftStreams::StreamGroup` resource defines a group of compute resources that will be running and streaming your game. When you create a stream group, you specify the hardware configuration (CPU, GPU, RAM) that will run your game (known as the _stream class_), the geographical locations where your game can run, and the number of streams that can run simultaneously in each location (known as _stream capacity_). Stream groups manage how Amazon GameLift Streams allocates resources and handles concurrent streams, allowing you to effectively manage capacity and costs. +Stream groups manage how Amazon GameLift Streams allocates resources and handles concurrent streams, allowing you to effectively manage capacity and costs. Within a stream group, you specify an application to stream, streaming locations and their capacity, and the stream class you want to use when streaming applications to your end-users.

This offers a cost control measure at the expense of a greater startup time (typically under 5 minutes). Default is 0 when creating a stream group or adding a location. + * **Maximum capacity** : This indicates the maximum capacity that the service can allocate for you. Newly created streams may take a few minutes to start. Capacity is released back to the service when idle.

This helps to insulate your users from capacity-allocation delays. You pay for capacity which is held in this intentional idle state.
