Kong Gateway is an open-source API gateway built on NGINX that sits between clients and backend services to manage API traffic. It handles authentication, rate limiting, load balancing, and traffic control through a plugin-based architecture. Organizations use Kong to secure APIs, improve performance, and simplify microservices architecture. Available as free open-source software or paid enterprise editions with advanced features.
Kong Gateway acts as a middleman between clients and your backend services, handling API traffic management, security, authentication, rate limiting, and monitoring. It simplifies microservices architecture by centralizing common functionality like logging and transformations.
Yes, Kong Gateway is available as free open-source software that you can download, use, and modify. Kong also offers paid Plus and Enterprise plans with additional features like advanced analytics, developer portals, and dedicated support, but pricing requires contacting sales.
Kong is built on NGINX and uses Lua for plugin development. You can also create custom plugins using Go. The core gateway handles request routing and processing, while plugins extend functionality.
Kong offers more deployment flexibility (on-premises, multi-cloud, hybrid) while AWS API Gateway is limited to AWS infrastructure. Kong provides more customization through plugins but requires more technical expertise to manage. AWS API Gateway is easier to set up but has vendor lock-in.
Kong supports three main deployment modes: Serverless (fastest setup for development), Self-Hosted/Kubernetes (flexible production deployment), and Dedicated Cloud (fully managed auto-scaling option). You can run Kong with or without a database depending on your needs.
Yes, Kong includes native Kubernetes Ingress Controller support for seamless integration with container orchestration. Many organizations deploy Kong on Kubernetes for microservices management and API routing.
Kong supports OAuth2, JWT tokens, API keys, LDAP, basic authentication, and custom authentication through plugins. The enterprise version includes additional RBAC features for granular access control.
Yes. Kong can manage AI and large language model (LLM) traffic using its AI Gateway features built on top of the core API gateway. Kong’s AI Gateway can route requests to different LLM providers, enforce security and usage policies, track metrics like tokens and latency, and help optimize performance and cost across multiple models. These capabilities make it suitable for handling AI‑centric workloads, including LLM service integrations.
