npm/bigband is an open source tool coming out of testim.IO allowing developers to easily assemble multiple AWS resources (Lambda functions, DynamoDB tables, Kinesis streams) into fully functioning services. Main features include:

• a very simple and intuitive command interface

• automatically decides what needs to be deployed

• Manages and updates IAM policies making them essentially hands-free

• Allows reuse of service definitions from other NPM packages

This tool powers all of Testim's Lambda-based applications. It is now offered to the entire open source community.
