What is Zilla?
API Gateway for event-driven microservices
Zilla is open source software connecting web and mobile applications to event-driven microservices using standard protocols, such as HTTP, Server-Sent Events and Kafka.
Zilla is designed on the fundamental principle that every data flow is a stream, and that streams can be composed together to create efficient protocol transformation pipelines. This concept of a stream holds at both the network level for communication protocols and also at the application level for data processing.
Zilla's declarative configuration defines a routed graph of protocol decoders, transformers, encoders and caches that combine to provide a secure and stateless API entry point to your event-driven architecture.
For example, when deployed in front of a Kafka cluster, Zilla can be configured to support:
- HTTP request-response interaction with Kafka-based microservices
- HTTP event-driven caching populated by messages from a Kafka topic
- reliable message streaming from a Kafka topic via Server-Sent Events
- secure HTTP request-response APIs using JWT access tokens
- secure Server-Sent Events streams using continuous authorization via JWT access tokens
As a developer, you can focus on writing and testing your event-driven microservices with technologies such as Kafka consumers and producers, you can define your web and mobile APIs using Zilla, and then you can deploy securely at global scale.
