// UpdateGameServerGroupRequest returns a request value for making API operation for

// This action is part of Amazon GameLift FleetIQ with game server groups, which
// is in preview release and is subject to change.
//
// Updates GameLift FleetIQ-specific properties for a game server group. These
// properties include instance rebalancing and game server protection. Many
// Auto Scaling group properties are updated directly. These include autoscaling
// policies, minimum/maximum/desired instance counts, and launch template.
//
// To update the game server group, specify the game server group ID and provide
// the updated values.
//
// Updated properties are validated to ensure that GameLift FleetIQ can continue
// to perform its core instance rebalancing activity. When you change Auto Scaling
// group properties directly and the changes cause errors with GameLift FleetIQ
// activities, an alert is sent.
