Kong : Open source API Gateway

Kong is a widely used open source API gateway. It is built on top of NGINX and can be extended using their opensource plug-ins which are provided by Kong community or you can customize your own plug-in in Lua .

Pros:

• Reliable having pluggable features.
• Easy to maintain, install & flexible.
• Authentication, Rate limiting & traffic control, OAuth 2.0
• IP restrictions: whitelist or blacklist
• Supports serverless mechanism such as AWS Lambda, Apache OpenWhisk

Cons:

• Most of the enterprise features are paid & expensive.
• No multi factor authentication
• Database Abstraction Object (DAO) : Which eases migrations from one database schema to another with near-zero downtime.
• To upgrade their Kong cluster all at once, without requiring manual intervention to upgrade each node.

DB-less vs With Database:

No need to manage a database installation in db-less. Db-less is good fit for automation in CI/CD scenarios and more flexible with lightweight applications. Installation : docs.konghq.com/install/docker
