1. What is Google Cloud Storage?
Google Cloud Storage (GCS) is Google Cloud’s object storage service, designed for high availability, durability, and scalability. It’s ideal for storing website images, media content, backup files, or raw data for analytics.
GCS supports multiple storage classes—Standard, Nearline, Coldline, and Archive—allowing you to optimize costs based on data access frequency. It integrates seamlessly with BigQuery, AI platforms, and Kubernetes, making it a core component for cloud storage and data processing.
📌 For more details on GCS storage classes, you can refer to the official documentation: [Types of Cloud Storage].
2. Google Cloud Storage Pricing Components
The main pricing components of Google Cloud Storage (GCS) include storage space, operations costs (such as requests and data retrieval), and network transfer fees. However, there may also be additional charges—like lifecycle management or versioning—so it’s recommended to check the official [Google Cloud pricing page] for the latest and complete information.
2.1 Storage Costs (By Class and Region)
Using Taiwan (asia-east1) as an example, here’s the monthly storage pricing per GB:
| Storage Class | Price (per GB/month) | Recommended Use Case |
|---|---|---|
| Standard | $0.020 | Frequent access, e.g., website images |
| Nearline | $0.010 | Occasional access, e.g., monthly backups |
| Coldline | $0.005 | Quarterly or less frequent access |
| Archive | $0.0015 | Long-term archival and compliance storage |
📌 Note: Prices vary by region (e.g., Taiwan, Tokyo, Hong Kong). Multi-region storage is generally more expensive.
2.2 Operations Costs (Requests & Retrieval)
Every operation in GCS—such as updating or retrieving data—incurs fees. These include API calls (PUT, GET) and data retrieval.
| Operation Type | Standard | Nearline | Coldline | Archive |
|---|---|---|---|---|
| Data Retrieval (per GB) | $0.00 | $0.01 | $0.02 | $0.05 |
| Class A Requests (per 1,000) | $0.005 | $0.10 | $0.02 | $0.50 |
| Class B Requests (per 10,000) | $0.0004 | $0.001 | $0.01 | $0.05 |
Every operation in GCS—such as updating or retrieving data—incurs fees. These include API calls (PUT, GET) and data retrieval.
2.3 Network Transfer Costs
- Free: Uploading data into GCS.
- Charged: Downloading (egress) data to the public Internet.
| Egress Volume | Price (per GB) |
|---|---|
| 0 – 1 TB | $0.12 |
| 1 – 10 TB | $0.11 |
| 10 TB+ | $0.08 |
- Transfers between GCP services in the same region (e.g., VM ↔ Storage) are usually free.
3. GCS Cost Simulation Example
Let’s say you store 1 TB of images per month and generate:
- 1 million GET requests (Class B)
- 110 GB of Internet egress
| Item | Quantity | Unit Price | Estimated Cost |
|---|---|---|---|
| Storage (Standard) | 1,000 GB | $0.020/GB | $20.00 |
| GET Requests | 1,000,000 | $0.004 per 1k | $4.00 |
| Network Egress | 110 GB | $0.12/GB × 110GB | $13.20 |
| Total | $37.20/month |
4. Tips to Save on Google Cloud Storage
- Choose the Right Storage Class
- Google Cloud Storage offers four main storage classes, with pricing ranging from high to low: Standard, Nearline, Coldline, and Archive.
- By aligning your data with the right storage class—based on access frequency and retention needs—you can significantly optimize costs.
- We recommend using an Object Lifecycle Policy, which automatically transitions data to a cheaper storage class according to predefined rules, helping you reduce long-term storage costs without manual effort.
- Combine or Compress Small Files
- GCS request fees are based on operation counts. Too many small files = higher PUT/GET costs.
- Consider bundling small files into larger compressed archives (e.g., .tar.gz) or using batch writes to reduce the number of requests.
- This approach not only lowers request costs but also improves read efficiency and boosts overall performance.
- Use Cloud CDN for Static Content
- For frequently accessed static assets—such as images, videos, and JS/CSS files—pairing GCS with Google Cloud CDNis highly recommended.
- By caching content at edge locations, you can reduce external GCS traffic and further cut down on egress costs.
- This also greatly improves load times and enhances the overall user experience.
- Keep Services in the Same Region
- Cross-region transfers incur additional fees, while VM-to-Storage transfers within the same region are usually free.
- It’s best to keep Compute Engine, Cloud Functions, and Storage in the same region to avoid unnecessary network expenses.
- When deploying in Taiwan’s asia-east1 region, you can benefit from lower latency and local compliance advantages.
- Placing compute resources and Storage in the same region eliminates cross-region transfer costs entirely.
5. A Note for Taiwan Users: Billing & Tax Considerations
Google Cloud opened its Taiwan (asia-east1) region in 2022.
However: Direct payments via a Google account are treated as overseas transactions, which means:
- VAT applies
- Exchange rate risks exist
✅ If you purchase through a local Google Cloud reseller in Taiwan:
- Some services may come with discounted rates.
- Enjoy local technical support and billing optimization services.
Final Thoughts: Master GCS Pricing to Save Big
At first glance, Google Cloud Storage pricing seems straightforward, but hidden costs quickly add up. From storage classes to request fees and data egress, every detail matters when managing cloud budgets.
