Google Cloud Functions

hi there Jimmy here always good to have you back Jimmy in today’s episode we’re gonna be focusing

on different cloud functions when building apps developers rely on various cloud services including storage messaging data analytics

and mobile development as developers expand their use seamless integration between these services can be a challenge

very true so today we’ll introduce Google cloud functions a solution that allows you to connect services together and extend

their behavior just by adding code we’ll also run through a quick demo of a self-paced lab that will allow you to

create deploy and test a cloud function cloud functions sounds pretty generic to me so what is it really Google cloud functions

can be summarized as a service compute solution for creating event-driven applications so let’s define an event an event

could be something like a change to data in a database or files added to a storage system you can

create a response to that event with a trigger a trigger is an indication that you’re interested

in a certain event or set of events adding a cloud function to the trigger allows you to respond

to that event because the software and infrastructure are fully managed by Google you only need

to provide the code a function can scale from a few requests to millions per day without any work from you

click here to view a great introduction by our product

manager Jason Polites about building service applications with Google cloud functions

so what can you do with clout functions let’s look at some examples

we can all relate to all right I’ve got one you know

when you subscribe to a newsletter Hogwarts number one fan and you magically get an email delivered to your inbox

yep that’s a trigger for a cloud function developers can also take advantage of cloud functions

to offload resource intensive work that wouldn’t be practical to run on a user’s device

an example could be to write a function that upon upload of an image to a storage bucket

a thumbnail of the image is created and then saved in another bucket it’s another

great example Jimmy and of course there are many opportunities to integrate with third-party services

and API stew now two quick laps the cloud functions lab is available

for use with the command line as well as through the Google cloud platform console you can check out the links to start to quick labs here in both labs

you will create a cloud function deploy and test the function and view logs so far in the lab

we’ve created a cloud function based on an HTTP trigger and deployed it once

deployed you can test a function provide a triggering event in this case a simple hello world message

you can see the success of the tested function in the output field you can easily

see the logs for your function well there we have it thanks for watching our quick video on Google cloud functions

don’t forget to keep visiting our on-air webinar series quick labs and our blogs all the links are below

you can also learn more about cloud functions there are on-demand courses on Coursera thanks for watching

and see you soon last week we discussed Google kubernetes engine and how it can easily scale deploy and automate

your application check out the video and the quick lab demo here
