[MUSIC] Hello there. Welcome back to another episode. >> And hello from me, Priyanka. >> Today, we'll introduce Google Cloud pub/sub. A messaging service that allows you to send and receive messages between independent applications. >> We'll also run through a quick demo of the self-paced lab, where we will explore various publishing and subscribing activities. >> And you want to know more how to test this with your own application after the lab? Well check out our free trial credit to get started on Google Cloud platform. [MUSIC] Let's first answer what Pub/Sub means as a service. >> Okay. So a publish/subscribe service is a messaging service where the senders of messages called publishers are decoupled from receivers of messages called subscribers. >> The published messages are categorized into topics. Subscribers who have expressed interest in a topic will either pull related messages or choose to get push messages from the topic. Key to the service is that neither party is required to have any knowledge of the other. [SOUND] >> Cloud Pub/Sub is great for distributing event notifications. Take an example of a service that accepts user sign ups. It can send notifications whenever a new user registers, and downstream services can subscribe to receive notifications of that event. There are even examples closer to home. You know that smart home technology you're so fond of. >> Yes, I do love my Google Home >> Well, the pops up services are part of the architecture that supports the streaming of data from residential sensors to the backing servers that are hosted on cloud. >> The ability of Cloud Pub/Sub to ingest millions of streaming events per second, from anywhere in the world. Also allows you to respond to the events as they happen. Cloud Pub/Sub forms part of cloud's extreme analytic solution which provides a number of useful applications. Such as performing sentiment analysis, identifying general patterns in trends and data, monitoring the performance and reach of campaigns, and crafting messages in real time. Time again for quick labs. The Cloud Pub/Sub lab is available for use with G Cloud command line tool as well as through the Google cloud platform console. You can check out the link to start quick labs here. And for a limited time, you can try this labs for free. >> Each of the labs cover the activities of setting up a topic to hold data, subscribing to a topic to access the data, and then publishing and consuming messages with a poll subscriber. The lab will take about 30 minutes to complete. >> So far in the lab, we've created a Pub/Sub topic using the Google Cloud Platform console and added a subscription. You can see the number of subscriptions listed for the topic is one. You can use the console to publish a message to Pub/Sub topic. In this case, we are publishing the message, hello demo. To view the message, you use the subscription to pull the message from the topic. Well there we have it. We hope you enjoyed this episode and would love to hear more about how you use or would use Google Cloud Pub/Sub. >> And don't forget, you can apply what you've learned today with a $300 free trial credit to get started on Google Cloud Platform. >> You can also learn more about Cloud Pub/Sub through a number of other Google Cloud training resources, all the links are listed below. Thanks for watching and see you soon. want to know more about Deployment Manager? Check out last week's episode where we dive into a lab and highlight the service.
