Is Google Cloud free?

Google Cloud is not completely free, but offers some free services. 1) The computing engine provides free f1-micro instances, up to 720 hours per month. 2) Cloud storage provides free 5GB of standard storage space. 3) Other services such as BigQuery also have free quotas, but you need to pay attention to usage restrictions.

introduction

Is Google Cloud really free? This question has aroused the curiosity and discussion among many developers. In this article, we will dive into Google Cloud’s free tier services, revealing which services are truly free and which are paid, and share some practical experience and skills to use them. After reading this article, you will learn how to maximize the use of Google Cloud's free resources while avoiding some common misunderstandings and pitfalls.

In the cloud computing field, Google Cloud is one of the top choices for many developers and businesses. Its free-tier service attracts a large number of new users, but to truly understand the boundaries and limitations of these services, some in-depth discussion and practical experience is required.

Free tier services for Google Cloud

Google Cloud offers a range of free services, but these services have their own usage restrictions and conditions. Let's take a look at the specific content and limitations of these services:

Compute Engine

Google Cloud's computing engine provides a certain amount of free computing resources. Specifically, you can use a f1-micro instance for free, up to 720 hours per month. This means that if you use it for 24 hours a day, you can use it for 30 days for free.

 # Compute Engine instance using Google Cloud from googleaapiclient.discovery import build

compute = build('compute', 'v1')

# Create an instance of f1-micro config = {
    'name': 'my-free-instance',
    'machineType': 'zones/us-central1-f/machineTypes/f1-micro',
    #Other configurations...
}

response = compute.instances().insert(project='your-project-id', zone='us-central1-f', body=config).execute()

In this example, we created an instance of f1-micro, which is part of the free tier service. It should be noted that the free tier service is limited, and if it exceeds 720 hours, you will have to pay.

Cloud Storage

The cloud storage service provided by Google Cloud also has a certain free quota. You can use 5GB of storage for free, but this is limited to the Standard Storage category.

 # Cloud Storage using Google Cloud
from google.cloud import storage

client = storage.Client()

# Create a bucket bucket = client.create_bucket('my-free-bucket')

# Upload a file blob = bucket.blob('my-file.txt')
blob.upload_from_string('Hello, World!')

In this example, we create a bucket and upload a file. It should be noted that the free 5GB of storage is shared throughout the project, and if this limit is exceeded, you will have to pay.

Other free services

In addition to computing engines and cloud storage, Google Cloud also provides some other free services, such as BigQuery, Cloud Functions, App Engine, etc. The free amounts of these services vary and need to be evaluated based on the specific usage.

Share experiences with free Google Cloud services

When using Google Cloud's free services, I have a few experiences and suggestions to share:

Monitor and manage resource usage

Google Cloud provides detailed monitoring and billing tools to help you understand resource usage in real time. With these tools, you can ensure that you don't exceed your free limit.

 # Use Google Cloud's monitoring tool from google.cloud import monitoring_v3

client = monitoring_v3.MetricServiceClient()

# Get CPU usage cpu_metric = 'compute.googleapis.com/instance/cpu/utilization'
results = client.list_time_series(
    name='projects/your-project-id',
    filter_=f'metric.type="{cpu_metric}"',
    interval=monitoring_v3.TimeInterval(start_time={'seconds': int(time.time()) - 3600}, end_time={'seconds': int(time.time())}),
    view=monitoring_v3.ListTimeSeriesRequest.TimeSeriesView.FULL
)

for result in results:
    print(f'CPU Usage: {result.points[0].value.double_value}')

In this example, we used Google Cloud's monitoring tool to get CPU usage. Through such monitoring, you can adjust the use of resources in a timely manner to avoid exceeding the free amount.

Avoid exceeding the free amount

The biggest challenge when using free services is how to avoid exceeding the free limit. My advice is to check resource usage regularly and adjust or suspend services in time when it is close to the free limit.

Learn and experiment with free services

Google Cloud's free service is perfect for learning and experimentation. You can use these resources to learn cloud computing technology and try different application scenarios without worrying about cost issues.

Performance optimization and best practices

Here are some performance optimizations and best practice suggestions when using Google Cloud's free services:

Optimize computing resources

If you are using a compute engine, you can optimize performance by tuning the instance type and configuration. For example, f1-micro instances are free, but have limited performance. If your application requires higher performance, you can consider using a higher configuration instance, but be aware that this will exceed the free limit.

 # Optimize Compute Engine Instance Configuration config = {
    'name': 'my-optimized-instance',
    'machineType': 'zones/us-central1-f/machineTypes/e2-medium',
    #Other configurations...
}

response = compute.instances().insert(project='your-project-id', zone='us-central1-f', body=config).execute()

In this example, we use the e2-medium instance, which is more performant than f1-micro, but requires a fee.

Optimize storage resources

When using cloud storage, you can optimize the use of storage resources by compressing files, using cold storage, etc. Google Cloud offers a variety of storage categories, and you can choose the most suitable storage method according to your needs.

 # Optimize storage costs using cold storage from google.cloud import storage

client = storage.Client()

# Create a cold bucket bucket = client.create_bucket('my-cold-bucket', storage_class='NEARLINE')

# Upload a file to cold storage blob = bucket.blob('my-file.txt')
blob.upload_from_string('Hello, World!')

In this example, we used cold storage (NEARLINE) to store files, which can significantly reduce storage costs.

in conclusion

Google Cloud's free services provide developers and businesses with a low-cost way to get started, but to truly make good use of these services, you need to have an in-depth understanding of their restrictions and usage conditions. Through the introduction and sharing of experience in this article, I hope you can better use Google Cloud's free resources while avoiding some common misunderstandings and pitfalls. In practical applications, rational planning and optimizing resource usage is the key, which not only helps you save costs, but also improves the performance and reliability of your application.
