LCA as AWS Lambda: Tenant Configuration
You can use AWS Lambda: Tenant configuration to implement LCA.
Configuring Life Cycle Actions Hooks in Tenant Configuration
Add the Life Cycle Actions and hook names for the entityTypes /
					relationTypes in your tenant's L3 Configuration for the
				appropriate Lambda Functions.
Sample L3 Configuration:
{
    "uri": "configuration/entityTypes/Organizations",    
    "label": "Organizations",
    "lifecycleActions": {
        "beforeSave": [
                         "Lambda/BinaryJSON/NameConcatenate"
                      ]
}
}Configuring Business Model
Actions deployed on AWS Lambda are specified with the Lambda/ prefix.  Also,
				for AWS Lambda actions transfer protocol can be optionally specified, so that it
				looks like Lambda/[Protocol/]ActionName. Currently, the following
				two protocols are supported:
- JSON (for Lambda actions using LCA framework up to 2016.3.2)
 - Binary JSON (for Lambda action using LCA framework starting from 2017.1)
