Resources created by the Snapshot Manager template
The following resources are created when you launch a Snapshot Manager stack using the Snapshot Manager CloudFormation template:
Table: Snapshot Manager CloudFormation template resources
Resource | Description |
|---|---|
EBS Volume (AWS::EC2::Volume) | The volume size and availability zone are specified during the stack creation process. |
EC2 Instance (AWS::EC2::Instance) | The instance type along with the required network and security configuration settings are specified during the stack creation process. |
VolumeAttachment (AWS::EC2::VolumeAttachment) | An EBS volume gets attached to the Snapshot Manager EC2 instance that is created. |
Instance Profile (AWS::IAM::InstanceProfile) | A new profile is created for the Snapshot Manager EC2 instance. This profile then assigns the specified IAM role to the EC2 instance. |
IAM Role (AWS::IAM::Role) | A new IAM role is created and attached to the Snapshot Manager instance during the stack creation process. The role is assigned all the AWS permissions that Snapshot Manager requires. This new role is created only if you have not specified any existing IAM role name in the CFT form (the Snapshot Manager System Configuration > IAM Role field is empty). |
Security Group (AWS::EC2::SecurityGroup) | An AWS security group is created internally for the Snapshot Manager deployment. The security group contains rules that allow inbound and outbound traffic for the following:
Refer to the AWS documentation for more information on security groups: |
Launch Configuration (AWS::AutoScaling::LaunchConfiguration) | A new launch configuration is created and is then used by the Auto Scaling Group (ASG) to scale the instance if the original Snapshot Manager EC2 instance status is marked as unhealthy. |
Auto Scaling Group (AWS::AutoScaling::AutoScalingGroup) | A new Auto Scaling Group (ASG) is created and the Snapshot Manager instance is attached to it. If the original Snapshot Manager EC2 instance becomes unhealthy, this ASG automatically creates a new Snapshot Manager instance and attaches the existing Snapshot Manager metadata volume to the new instance. |
