Google Cloud Pub Sub WebSocket demystified by our experts. Read on to learn more, 

At Bobcares, we offer solutions for every query, big and small, as a part of our Google CLoud Platform Support Services.

Let’s take a look at how our GCP Support Team is ready to introduce customers to Pub Sub WebSocket in Google Cloud Platform.

An introduction to Google Cloud Pub Sub WebSocket

WebSocket is a protocol that is responsible for two-way interactive communication, while Pub Sub is a messaging pattern.

With more applications welcoming an event-driven model, user interfaces have to be up to the challenge of achieving low-friction simple connectivity to the messaging services of the overall architecture. While there are several different options available currently. WebSocket is the most popular. In fact, we can distribute a stream of messages via Pub Sub to the browser frontend via WebSocket protocol.

Today, our Support Team is going to give us a peek at streaming Pub Sub messages over WebSockets in Google Cloud. It involves the following steps:

• Creating and configuring a VM instance with the components we need to stream the pub Sub subscription payloads to browser clients.
• Configuring a process on the virtual machine to subscribe to a Pub Sub topic in addition to the output of individual messages to a log in Google Cloud.
• Installing a web server in order to serve static content as well as stream shell command output to the WebSocket clients.
• Accessing WebSocket stream aggregation as well as individual message samples in a browser via CSS, HTML, and JavaScript.

According to our Support Tech, we may also need to use pulltop, a Node.js program. This program subscribes to a Pub Sub topic and streams the incoming messages to standard output.

Additionally, websocketd is a small command-line tool responsible for wrapping an existing CLI program and making it accessible via WebSocket.

In fact, combining websocketd and pulltop enables us to access messages received from the Pub Sub top streaming to the browser via WebSockets in Google Cloud.
