The tool, which was first announced at the AWS re:Invent conference last year, is designed to help companies transform their on-prem software into cloud-based software as a service. In the charter for the software, the company describes its mission this way: “Our mission is to create a community-driven suite of extensible building blocks for Software-as-a-Service (SaaS) builders. Our goal is to foster an open environment for developing and sharing reusable code that accelerates the ability to deliver and operate multi-tenant SaaS solutions on AWS.”
