Description

This course has been designed to teach you how to deploy and implement Google Cloud Platform solutions. The content in this course will help prepare you for the Associate Cloud Engineer exam.

Learning Objectives

  • To learn how to deploy Kubernetes Engine resources on Google Cloud Platform
  • To learn how to deploy and implement App Engine and Cloud Functions resources
  • To learn how to use Cloud Launcher and Deployment Manager

Intended Audience

  • Those who are preparing for the Associate Cloud Engineer exam
  • Those looking to learn more about GCP networking and compute features

Prerequisites

To get the most from this course then you should have some exposure to GCP resources, such as Kubernetes Engine, App Engine, Cloud Functions, Cloud Launcher, and Deployment Manager. However, this is not essential.

Transcript

In previous lessons, you learned how to deploy an app to the GCP app service and how to deploy multiple versions of the app. When you deploy multiple app versions, you can split traffic across them. What you can do is specify a percentage of traffic that should go to one version and another percentage that should go to another version or even several other versions within a service. 

Traffic splitting is a great way to conduct A/B testing between different versions and it provides more control over the process of rolling out features. 

You can split traffic by IP address or via cookie splitting. You can also configure random splitting. 

If you decide to split traffic by IP address, the application, when it receives a request, hashes the IP address to a value between zero and 999. It then uses that number to route the request to a version of your app. 

When cooking splitting, the application will look in the HTTP request header for a cookie named GOOGAPPUID. This cookie contains a value between zero and 999. If the cookie exists, the value is used to route the request. In the event there is no cookie, the request is routed randomly. 

Randomly splitting traffic results in a split that's based on a weighted random assignment. Incoming requests are randomly routed to a version of the app in the traffic split. 

In the next demonstration, I'm going to show you how to split traffic across two versions of an app hosted by app service.
