HRPaaS: A Handwriting Recognition Platform as a Service  Based on Middleware and the HTTP API
In this paper, we present a new Handwriting Recognition Platform as a Service (HRPaaS) using cloud infrastructure as a service(IaaS), middleware, and HTTP application programming interface (API) technologies. Based on the OpenStack cloud IaaS architecture, a handwriting recognition HTTPAPI service is designed to provide a highly reliable, real-time, customized handwriting character recognition service for application developers. Using middleware and cloud computing technologies, the computing resources, HTTPAPI response service pool, and backend handwriting recognition service pool can be loosely coupled and integrated to achieve fast and flexible deployment of the HRPaaS.
