AWS Launch Template is more advanced than Launch Configuration.
Based on my work experience, it has been listed as below:
1. Version Management
It is possible to create one or more numbered launch template versions. Each version can have different launch parameters, as depicted in the above diagram. But Launch configuration needs manual maintenance.
2. Leverage the latest features
Launch template can leverage the latest features of Amazon EC2, such as T2 Unlimited instances.
3. EC2 Launch Model
Launch configuration creates EC3 instances using the given Auto Scaling group, where as launch templates enable you to store launch parameters.4.Subnet collection
In terms of subnet configuration script, launch template specifies exactly one subnet, rather than a list used in launch configuration.
