What is Streamlio Cloud Preview

Streamlio Cloud Preview is a sandbox deployment of the Streamlio Cloud service. It supports the core functionality of Streamlio Cloud and Apache Pulsar for experimentation and learning about Streamlio Cloud and Apache Pulsar.

There are a few important differences between Streamlio Cloud Preview and Streamlio Cloud including the following (see the sections further below for more details):

  • Not for production. We do not provide official customer support for Streamlio Cloud Preview--it is provided "as is" for learning and education purposes only.

  • Not for heavy workloads. Streamlio Cloud Preview has resource limits applied. As a result, Streamlio Cloud Preview is not appropriate for performance testing, large scale workloads, production or staging environments, etc. See below for more details on specific limits.

  • Management interfaces. Some Pulsar CLI functionality will work with Streamlio Cloud Preview, however Streamlio Cloud Preview does not support all functions of the Apache Pulsar nor Streamlio CLI interfaces.

We are definitely interested in hearing about your experience with Streamlio Cloud Preview. If you are interested in our production-ready offering, please take a look at Streamlio Cloud for more information.
