Advantages

CAE is a product of Huawei's success in cloud transformation and technological innovation. This one-stop application cloud platform has the following advantages over traditional platforms:

**Table 1** Advantages
Application Lifecycle	Traditional Hosting	CAE Hosting
Environment preparation	Inefficient obtaining of resources (> 1 day) Low resource utilization (< 30%)	Self-service and efficient resource obtaining (in minutes) Pay-per-use payment (auto scaling)
Installation and deployment	Siloed system Manual deployment	Developers only need to use CAE and source code software repository for one-click automatic deployment and updates.
Component configuration	Complex items All involved environments configured separately Error-prone	The configuration file is decoupled from the environment so that the independently maintained file is used together by multiple environments.
Component upgrade	Patch installation Manual upgrade Services interrupted	rolling upgrades even distribute services to new and old instances to avoid interrupting services.
Component O&M	Application breakdown or crash Slow service response Insufficient system resources Difficult fault locating	Real-time graphical display of monitoring metrics Monitors CPU usage, running logs, and key events in real time Application performance analysis Supports application discovery, dependency, and KPI aggregation. Tracing and monitoring Monitors platform, resources, and applications while analyzing microservice traces. Microservice governance Provides SLA metrics for microservice APIs (throughput, latency, and success rate) and ensures continuous services with monitoring and governance in real time (response in seconds).
