goPaddle is a container-based software development lifecycle (SDLC) platform that can forward and reverse engineer applications in a portable manner across different infrastructure and platform clouds. It uses containers to improve application performance and reduce costs. The forward engineering process involves creating a blueprint, adding application artifacts, testing across clouds, and deploying. The reverse engineering process discovers existing applications and infrastructure, converts them to blueprints, and deploys them to clouds. goPaddle allows applications to be portable across cloud layers, vendors, and operating systems. It offers benefits like faster development, more application density, and no vendor lock-in.
