Parameter Store KVS

A simple Key-Value store interface library for Amazon Systems Manager Parameter Store service. It can be used stand-alone for simple use cases when all you need is to just put a value or get a value to/from the ParameterStore. It is also compatible with Hyperledger Fabric Node SDK, so that you can put Connection Profile configuration to the Parameter Store and share it across all instances of your blockchain client application.
