Get Started

These tutorials introduce you to how to develop iOS applications for common messaging requirements, and they will get you up-to-speed and sending messages with PubSub+ as quickly as possible. They cover pub/sub, message persistence, request/reply, and more.

There are three ways you can get started using a PubSub+ event broker:

  1. If you have PubSub+ event brokers already deployed, obtain the hostname or IP address of an event broker to test against, a username and password to access it, and a Message VPN in which you can produce and consume messages.
  2. You can set up a software event broker as a container or machine image. For more information, see one of the following:
  3. You can spin up an event broker service, which is a SaaS-based software event broker running in PubSub+ Cloud.
