How to create and manage virtual machines on GCP

Are you ready to take your IT infrastructure to the cloud? One of the first steps in transitioning to cloud computing is creating virtual machines. In this article, we will explore the process of creating and managing virtual machines on Google Cloud Platform (GCP).

What are virtual machines?

Before we delve into how to create and manage virtual machines on GCP, let's first define what virtual machines are. Virtual machines, also known as VMs, are software-based computers that run on top of a physical host machine. They operate like a physical machine with their own virtual CPU, memory, storage, and networking resources. The advantage of virtual machines is that they allow for multiple operating systems and applications to run on a single physical machine, reducing hardware costs and increasing efficiency.

Creating virtual machines on GCP

Google Cloud Platform offers several ways to create virtual machines, including the Cloud Console, the Cloud SDK command-line tool, and the API. In this article, we will focus on using the Cloud Console.

Step 1: Create a project

To create virtual machines on GCP, you need to first create a project. A project is a collection of resources, such as virtual machines and storage buckets, that belong to a particular application or service. To create a project:

1. Open the GCP Console.
2. In the top navigation bar, select a billing account and a folder.
3. Click Create Project.
4. In the New Project dialog, enter a name for the project and click Create.

Once you have created a project, you can proceed to create virtual machines.

Step 2: Choose a machine type

GCP offers a variety of machine types, each with a different combination of CPU, memory, and other resources. You can choose the machine type that best fits your workload. To select the machine type:

1. In the GCP Console, navigate to the Compute Engine section.
2. Click Create Instance.
3. In the Create a new instance dialog, under the Machine type section, select the machine type that best fits your workload.

Step 3: Choose an operating system

The next step is to choose an operating system for your virtual machine. GCP offers a variety of operating systems, including Linux and Windows. To select the operating system:

1. In the Create a new instance dialog, under the Boot disk section, click Change.
2. In the Operating system tab, select the operating system that you want to use.
3. Select the version of the operating system that you want to use.

Step 4: Configure other settings

In addition to the machine type and operating system, you can configure several other settings, such as the machine name, the boot disk size, and the network configuration. For example, you can set up firewall rules to allow or deny incoming and outgoing traffic to and from your virtual machine. You can also configure the metadata settings, which allow you to provide custom data to your virtual machine.

Step 5: Create the virtual machine

Once you have configured all the settings, you can create the virtual machine by clicking the Create button in the Create a new instance dialog. It may take a few minutes for the virtual machine to start up.

Managing virtual machines on GCP

Now that you have created a virtual machine, you need to know how to manage it. GCP offers several tools for managing virtual machines, including the Cloud Console, the Cloud SDK command-line tool, and the API. In this article, we will focus on using the Cloud Console.

Viewing virtual machines

To view the virtual machines in your project:

1. In the GCP Console, navigate to the Compute Engine section.
2. Click VM instances.

Here, you can see a list of all the virtual machines in your project, including their machine type, status, and IP address.

Starting and stopping virtual machines

To start or stop a virtual machine:

1. In the VM instances page, locate the virtual machine that you want to start or stop.
2. Click the checkbox next to the virtual machine name to select it.
3. Click the Start or Stop button in the upper bar.

Editing virtual machines

To edit a virtual machine:

1. In the VM instances page, locate the virtual machine that you want to edit.
2. Click the virtual machine name to open its details page.
3. Click the Edit button in the upper bar.

Here, you can edit various settings, such as the machine type, operating system, and network configuration. You can also add or remove disks, edit the metadata, and configure other advanced settings.

Deleting virtual machines

To delete a virtual machine:

1. In the VM instances page, locate the virtual machine that you want to delete.
2. Click the checkbox next to the virtual machine name to select it.
3. Click the Delete button in the upper bar.

Note that deleting a virtual machine will also delete all the data on its boot disk. To preserve the data, you can create a snapshot of the boot disk before deleting the virtual machine.

Migrating virtual machines

If you need to move a virtual machine to another project or region, you can use the migration feature in GCP. This allows you to move the virtual machine and its associated disks, snapshots, and IP addresses to another project or region while preserving the machine's configuration and state.

To migrate a virtual machine:

1. In the VM instances page, locate the virtual machine that you want to migrate.
2. Click the virtual machine name to open its details page.
3. Click the Migrate button in the upper bar.

Follow the prompts to select the destination project or region, and review the migration details before starting the migration.

Conclusion

Creating and managing virtual machines on Google Cloud Platform is a straightforward process that can help streamline your IT infrastructure and reduce costs. By following the steps outlined in this article, you can create virtual machines with the appropriate machine type, operating system, and configuration, and manage them efficiently using the Cloud Console. With GCP's powerful tools and services, you can take full advantage of the benefits of cloud computing and focus on building and scaling your applications with confidence.
