Deploying .NET 6 Workload To Google App Engine Flexible Environment

Introduction

In this article, we will learn more about the following features of Google App Engine.

  • What is Google App Engine 
  • Features of GAE
  • Compute engine vs GAE comparsion 
  • App Engine Environments 
  • App Engine scaling 
  • Deploy .NET 6 workloads to GAE 

What is App Engine

Google App Engine lets app developers build scalable web and mobile backends in any programming language on a fully managed serverless platform.

Supports

  • GO,Java,.NET Node JS, Python, and Ruby using pre-configured Runtime.
  • Use custom runtime(Containers) and write code in any language.
  • Easy connectivity with cloud services (Cloud SQL etc.)

No Usage Charges

Pay for use(Automatically scales depending on app traffic)

Features

  • Automatic load balancing and Auto scaling
  • Managed platform updates and application health monitoring
  • Application versioning
  • Traffic Splitting

Compute Engine Vs. App Engine

Compute Engine

  • IAAS
  • More flexibility

More Responsibility

  • Choose Image,
  • Hardware,
  • Availability
  • Fine grain access controls

App Engine

  • PAAS
  • Serverless
  • Lesser Responsibility
  • Lesser Flexibility

App Engine Environments

Standard - Application runs in language specific runtime

  • Complete isolation from OS.DISK

V1:Java,Python,PHP,GO(Older versions)

Restricted network access for python and PHP runtime

V2:Java,Python,PHP,GO(newer versions)

Full network access and no restrictions.

Flexible: Run Application instances as Docker containers

  • Makes use of compute engine VM in
  • Supports any runtime with built-in support for Python,Java,Node.js,Go,Ruby,PHP,.NET

App Engine Scaling Instances

Automatic - Scale based on Instance load

  • Continuously running workloads

Auto Scale based on

  • CPU Utilization
  • Throughput utilization
  • Concurrent Users

Basic - Instances are created when requests are received

  • Instances are shut down to Zero When there is no traffic
  • Not supported by APP Engine flexible

Manual - configure the number of Instances

Adjust number of instances manually over a period of time.

Google App Engine Flexible Environment

Deploying .NET 6 Workloads to GAE 

Prerequisites

  • Google free tier or paid account.
  • Basic knowledge of using Google cloud services.
  • Create Docker images and deploy them to the Google container registry https://www.c-sharpcorner.com/article/how-to-create-docker-image-of-net-6-workloads-and-push-it-to-google-container-r/

Deploy Application image to GAE 

gcloud app deploy --image-url=gcr.io/buildcustomimage/custom-image:0.1

Note
Google app engine API and App Engine Admin API must be enabled. App engine account must have access to Google container Registry.

Navigate to the Google App engine, and you will see a new default service created,

Google App Engine Flexible Environment

To get Application Url 

gcloud app browse.

Summary
