Architecture
Built on NGINX and OpenResty, optimized for high performance but adds latency with Lua scripting
Built using Java and Spring Boot, featured a modular architecture with a gateway, management API, and analytics components
Built on Apache APISIX, high-performance with LuaJIT-based execution, lower latency than Kong
Deployment
Easy installation, supports Kubernetes, VM, and bare-metal deployments
Complex and difficult to install, limited environments
Easy installation with flexible deployment, supports multi-cloud, hybrid-cloud, and edge environments
Serverless Support
