In this guide, we detail the process of deploying a simple, scalable, and highly available application on Google Cloud Platform (GCP). Throughout this tutorial, you’ll learn about autoscaling, instance groups, load balancers, and strategies to ensure high availability while maintaining an easy, streamlined deployment process.

​
Key Concepts and Best Practices

The application should adhere to the following best practices:
  • Scalability: The deployment must smoothly handle increasing load.
  • High Availability: The system should continue running even when individual resources fail.
  • Easy Deployment: The process of rolling out the application should be straightforward and automated.
The image is a summary of load balancing concepts, including auto-scaling instance groups, load balancers, high availability, and easy deployment, with a use case for deploying an application on GCP.

Application Deployment Requirements

To build a resilient application on GCP, consider the following minimum requirements. This diagram illustrates the essential components necessary for successful deployment:
The image outlines minimum requirements for an application on GCP, including scalability, high availability, and easy deployment, and poses a question about setting up an application during VM creation.

​
Integrating GCP Components

A robust application depends on the seamless integration of multiple GCP components. Some critical questions to address include:
  • How do we connect an instance group to a load balancer?
  • What methods are effective for scaling an instance group?
  • How can we ensure the application code is deployed automatically to new instances?
Keep in mind that when using an instance group, machines might be terminated and replaced frequently. It is therefore essential to automate the deployment process so that every new instance automatically includes the latest version of your application code.

​
Practical Implementation

In this demo, we integrate a load balancer, an autoscaling instance group, and an automated deployment procedure. The main objective is to guarantee that each new instance in the group has the required application code installed seamlessly. Let’s dive into the solution and explore how these GCP components work together to deliver a scalable, highly available, and straightforward deployment process.
