Cloud Application Engine (CAE) is a serverless PaaS platform that provides simplified hosting for applications. It helps users migrate microservice applications to the cloud without O&M IaaS on a pay-per-use basis, effectively reducing costs and improving efficiency.

CAE provides the following capabilities:

Fast deployment in minutes based on source code, software packages, or container images
Mainstream languages and runtime systems such as Java, Node.js, and Tomcat
Seamless hosting for web, microservice, and API applications
Pay-per-use auto scaling based on resources or custom service indicators, coping with unpredictable user access traffic
Standard pluggable runtime systems, allowing you to focus on application development
Built-in application governance, implementing self-healing and quick recovery of large-scale cloud-native applications
