What is Google Cloud Compute Engine (GCE)

Google Cloud Compute Engine (GCE) is a service that provides virtual machines (VMs) on Google Cloud Platform (GCP).

These VMs run on the same infrastructure as Google’s most popular products, such as Gmail and Google Search. Compute Engine allows businesses and developers to run scalable, flexible, and reliable applications and workloads in the cloud. 

Whether it's hosting websites, running complex analytics, or deploying machine learning models, Compute Engine provides the necessary computing resources to meet your needs.

In this article, we will learn what is Google Cloud Compute Engine (GCE), its features, uses, benefits, and working. Further, you can check out Google Cloud Platform courses to learn more about Google Cloud Compute Engine (GCE).

What is Google Cloud Compute Engine (GCE)

Google Cloud Compute Engine (GCE) is an Infrastructure as a Service (IaaS) component of the Google Cloud Platform. It allows users to run virtual machines (VMs) on demand, using Google's global infrastructure, which supports services like Google Search, Gmail, and YouTube.

The primary purpose of GCE is to provide scalable computing resources, enabling users to create and manage VMs with various configurations, including custom machine types, GPU accelerators, and global load balancing.

It supports both Linux and Windows operating systems and offers features like persistent disks, network management, and sustained use discounts. GCE is managed via a RESTful API, command-line interface, or web console, and pricing is based on a pay-per-use model with no upfront fees.

Features of Google Cloud Compute Engine 

The following are the key features of Google Cloud Compute Engine 

1. Google Cloud Compute Engine provides customizable virtual machines, giving users control over resources like virtual CPUs (vCPUs), memory, and storage.  

2. Compute Engine supports both vertical scaling (adding resources to a single VM) and horizontal scaling (adding more VMs to your environment), allowing applications to grow without limitations. 

3. With multiple data centers across the globe, Google Cloud Compute Engine ensures low-latency access and redundancy. 

4. Computer Engine is built on Google’s high-performance infrastructure.  

5. GCE integrates seamlessly with other Google Cloud services such as Cloud Storage, BigQuery, and Kubernetes Engine.  

6. Google Cloud offers persistent storage options like SSDs and standard persistent disks.  

7. For cost-effective computing, Compute Engine offers preemptible VMs, which are short-lived instances available at a significantly lower price compared to standard VMs. These are ideal for fault-tolerant and batch processing workloads. 

How to Use Google Cloud Compute Engine?

Google Cloud Compute Engine works by allowing users to create virtual machines that run on Google’s infrastructure.

It allows VMs to be configured with custom specifications, such as the amount of CPU, memory, and storage needed for the workload.  

Here are the step-by-step instructions for using Google Compute Engine (GCE) to create and manage virtual machine (VM) instances: 

Step 1: Set Up Google Cloud Platform (GCP) 

Create a GCP Account: 

● Go to the Google Cloud Console. 

● Sign up for a Google Cloud account if you don’t already have one. 

● Set up billing (GCE is a paid service, but new users get free credits). 

Create a Project: 

● In the Cloud Console, click on the project dropdown and select "New Project." 

● Give your project a name and click "Create." 

Enable Compute Engine API: 

● Go to the API & Services dashboard. 

● Search for "Compute Engine API" and enable it. 

Step 2: Create a Virtual Machine (VM) Instance 

Navigate to Compute Engine: 

● In the Cloud Console, go to Compute Engine > VM Instances. 

Create an Instance: 

● Click "Create Instance" or "Create". 

Fill in the following details: 

● Name: Give your VM a unique name. 

● Region and Zone: Choose the geographic location for your VM. 

● Machine Type: Select the CPU and memory configuration (e.g., e2-medium). 

● Boot Disk: Choose an operating system image (e.g., Ubuntu, Debian, Windows Server). 

● Firewall: Allow HTTP/HTTPS traffic if hosting a web server. 

Advanced Configuration (Optional): 

● Add GPUs or TPUs for machine learning workloads. 

● Attach additional disks for storage. 

● Configure networking (e.g., assign a static external IP). 

● Click "Create": 

Your VM instance will be provisioned and started automatically. 

Step 3: Connect to Your VM 

SSH into the VM: 

● In the VM Instances list, find your VM and click the "SSH" button next to it. 

● A browser-based SSH terminal will open, allowing you to access the VM. 

Alternative Methods: 

● Use the gcloud command-line tool:gcloud compute ssh [INSTANCE_NAME] --zone=[ZONE] 

● Use third-party SSH clients (e.g., PuTTY) with the VM's external IP and SSH key. 

Step 4: Manage Your VM 

● Start/Stop/Delete Instances: In the VM Instances list, use the options to start, stop, or delete instances. 

● Resize the VM: Stop the instance, change the machine type, and restart it. 

● Attach Disks:Go to Compute Engine > Disks to create and attach additional persistent disks. 

● Take Snapshots: Create snapshots of your disks for backup.Go to Compute Engine > Snapshots and click "Create Snapshot." 

Step 5: Configure Networking 

Set Up Firewall Rules: 

● Go to VPC Network > Firewall. 

● Create rules to allow or block traffic to your VM (e.g., open port 80 for HTTP). 

Assign Static IP: 

● Go to VPC Network > External IP Addresses. 

● Reserve a static IP and assign it to your VM. 

● Load Balancing: Set up a load balancer to distribute traffic across multiple instances. Go to Network Services > Load Balancing. 

Step 6: Monitor and Optimize 

Use Cloud Monitoring: Go to Operations > Monitoring to view metrics like CPU usage, disk I/O, and network traffic. 

Enable Autoscaling: Create a Managed Instance Group (MIG) and configure autoscaling policies. Go to Compute Engine > Instance Groups. 

Check Billing: Monitor your usage and costs in the Billing section. 

Step 7: Clean Up 

Delete Unused Resources: Delete VM instances, disks, and snapshots you no longer need to avoid unnecessary charges. 

Disable APIs: If you’re done using GCE, disable the Compute Engine API to prevent accidental usage. 

By following these steps, you can effectively use Google Compute Engine to deploy, manage, and scale your cloud-based workloads. Let me know if you need further clarification!

Drawbacks of Using Google Cloud Compute Engine 

● GCE can become expensive, especially for high-demand or continuously running workloads. Pricing models based on resource usage, storage, and networking can be difficult to predict without proper cost management and optimization strategies. 

● For beginners, the Google Cloud Platform, including Compute Engine, can be challenging to navigate. Users need to be familiar with cloud concepts, configurations, and best practices to maximize its potential. 

● Some older or proprietary software may not be compatible with GCE's virtualized environment, making migration or integration more complex for certain businesses. 

● While preemptible VMs offer cost savings, they are subject to being terminated with little notice, making them unsuitable for applications that require high availability or cannot tolerate interruptions.
