Pub/Sub and Pub/Sub Lite are horizontally scalable
and managed messaging services. These services can handle high volume and
support large storage requirements.

- Pub/Sub is usually the default solution for most application integration and analytics use cases. It is feature-rich and fully managed.
- Pub/Sub Lite is recommended for applications where messaging throughput is more stable, workloads can benefit from a partition-based system, and cost is a significant concern.
