Spinning Apache Kafka® Microservices With Cadence Workflows – Part 2
In “Spinning your Workflows With Cadence!” we explored Cadence, a new scalable, developer-focused, open source workflow engine. Cadence is a great solution for highly fault-tolerant stateful workflow management, also known as “orchestration” (based on the idea of a conductor directing an orchestra). However, another popular architectural alternative for large-scale message-based distributed systems uses a loosely-coupled approach, known as “choreography” (based on the idea of dancers interacting with their immediate neighbours). Apache Kafka is a common example and enables large numbers of microservices to communicate with each other scalably and at low-latency, with no central state management required.

Redis™ Streams vs Apache Kafka®
The Redis Streams data type is newer than the Redis Pub/Sub data type, and is designed to support “disconnected” distributed streaming applications. The data type itself is essentially an append-only data structure, stored in memory—basically preserved messages!

Redis™️ Pub/Sub vs Apache Kafka®: An Introduction and Connected vs Disconnected Delivery
Redis Pub/Sub is the oldest style of messaging pattern supported by Redis, and uses a data type called a “channel” which supports typical Pub/Sub operations, such as Publish and Subscribe. It’s considered loosely coupled because publishers and subscribers don’t know about each other. Publishers publish messages to a channel (or multiple channels), and subscribers subscribe to 1 or more channels. A channel can have 0 or more subscribers, and the messages are delivered to all the current connected subscribers.
