Redis is widely use as a queue yes, it's supported by tools like Celery (a Python distributed task queue that has multiple backends, both RabbitMQ and Redis, and is/was used by Instagram) or Sidekiq, a similar tool for Ruby.

Lots of "simpler" web apps use distributed queues as a means to offload workload.

But Redis is much more than just a backend, as you hinted it can be used as a data store, as a cache. Until the future release of Redis 6 has been an async only architecture (it will acquire threaded I/O). It has persistence, native support for publisher/subscriber communication, many data types (hashes, sorted sets), support less mainstream features like HyperLogLog, has basic support for geolocalization operations and supports streams in input and output.

There's a lot you can do with Redis :)
