What is GCP? Google Cloud Platform Basic Introduction

GCP's full name is Google Cloud Platform.

Simply put, it's Google opening up the infrastructure they use to run YouTube, Gmail, and Google Search for enterprises to use as well.

GCP Development History and Market Positioning

GCP launched its first product, App Engine, in 2008—two years later than AWS. But Google chose a different path: focusing on building advantages in data analytics and machine learning.

According to Gartner's 2024 report, global public cloud market share:

Platform	Market Share	Positioning
AWS	32%	Widest services, most complete ecosystem
Azure	23%	Enterprise integration, Microsoft ecosystem
GCP	10%	Data analytics, AI/ML, containerization

Third in market share, but fastest growth rate. Why? Because more and more enterprises now need to handle big data and AI applications, and this is exactly GCP's strength.

GCP Integration Advantages with Google Services

Using GCP has a unique benefit: integration with Google's own services is seamless.

Directly integrated services:

• Google Workspace: Gmail, Google Drive, Google Meet can directly connect with GCP's data services
• Google Analytics / GA4: Website data can be imported to BigQuery with one click for deep analysis
• Google Ads: Ad data can be integrated with internal data for more precise ROI analysis
• YouTube: Video data analysis, streaming services can directly use GCP's infrastructure

If your enterprise already heavily uses the Google ecosystem, GCP's integration costs will be much lower than other platforms.

Global Data Center Distribution (Including Taiwan Changhua)

GCP currently has 40+ regions and 120+ availability zones globally.

What Taiwan users care about most: The Changhua data center officially launched in 2020.

What does this mean?

• Low latency: Local user connection latency can drop to below 5ms
• Data residency: Sensitive data can be ensured to stay within Taiwan
• Compliance: Meets local regulatory requirements like FSC and Personal Data Protection Act

For financial, healthcare, and government sectors, data residency is a key consideration when choosing cloud platforms. GCP's Taiwan data center gives these industries another option.
