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 of a significant concern.

For more information on Pub/Sub Lite, see the Pub/Sub Lite documentation.
