What is Google Cloud Platform (GCP)?

Google Cloud Platform (GCP) is a comprehensive suite of cloud computing services offered by Google. It provides a wide range of solutions, including computing resources, storage, databases, machine learning, networking, and more, all accessible over the internet. GCP enables organizations to efficiently build, deploy, and scale applications and services without the complexity or cost of managing physical infrastructure.

Since the launch of Google Search in 1998, Google has built one of the most extensive and robust IT infrastructures in the world. This infrastructure now supports billions of users across services like Gmail, YouTube, Google Photos, and Maps. In 2008, Google extended this powerful infrastructure to business customers, transforming it into a public service offering and introducing the Google Cloud Platform.

The services mentioned above are all part of Google’s extensive ecosystem, which is why it is collectively referred to as Google Cloud Platform (GCP). Beyond these, GCP offers numerous additional services and concepts, which will be explored in detail in this article.

Regions and Zones

The smallest unit in the hierarchy of Google Cloud Platform (GCP) is a Zone, which is a specific area where resources like virtual machines or storage are deployed.

For instance, when you create a virtual machine in GCP using Compute Engine, you choose a specific zone (e.g., Europe-west2-a). While zones are often perceived as standalone data centers, they don’t necessarily correspond to a single physical building. However, visualizing zones this way can help simplify understanding.

Zones are grouped into Regions, which are independent geographic areas and significantly larger than zones. For example, multiple zones such as Europe-west2-a, Europe-west2-b, and others are part of the Europe-west2 region. Regions allow you to strategically select the location of your GCP resources. Zones within the same region benefit from low-latency network connections, often under five milliseconds.

To build fault-tolerant applications, it is recommended to distribute resources across multiple zones within a region. This approach ensures resilience against unexpected failures. Additionally, many GCP customers deploy resources across regions to enhance performance for global users and to safeguard against the potential loss of an entire region, such as during a natural disaster.

Certain GCP services support Multi-Region deployments. For example, Google Cloud Storage allows data to be stored redundantly across multiple locations, separated by at least 160 kilometers within a designated region (e.g., Europe Multi-Region). Initially, GCP operated in 15 regions, but you can visit cloud.google.com for the latest updates on its global footprint.

History of Google Cloud Platform

Google Cloud Platform (GCP) traces its origins back to 1998 with the launch of Google Search, which laid the foundation for one of the world’s most extensive and powerful IT infrastructures. This infrastructure today supports billions of users across services such as Gmail, YouTube, Google Photos, and Maps.

In 2008, Google began offering this robust infrastructure to business customers by launching Google Cloud Platform, transforming its consumer-focused capabilities into a public cloud offering. Over the years, GCP has introduced numerous innovations, such as BigQuery in 2010 for serverless analytics, Cloud Storage in 2013, and Compute Engine in 2014, which introduced Infrastructure-as-a-Service (IaaS). In the same year, the introduction of Google Kubernetes Engine (GKE) revolutionized container management, setting GCP apart as a leader in cloud computing.

Today, GCP stands as a powerhouse in the cloud industry, offering state-of-the-art solutions that empower businesses to innovate, scale, and thrive in an increasingly digital world.

Google Cloud Services Interaction

Google Cloud Platform (GCP) offers three primary methods for interacting with its services and resources:

1. Google Cloud Console

The Google Cloud Console is a user-friendly, web-based interface that allows you to manage and configure GCP projects and resources. It features an intuitive dashboard where you can create new projects or manage existing ones, monitor services, and configure settings seamlessly.

2. Command-Line Interface (CLI)

For users who prefer command-line tools, GCP offers the Cloud SDK, which includes the gcloud CLI. This tool provides the ability to manage resources directly from a terminal window. For example, you can create a virtual machine using the gcloud compute instances create command. The CLI can be used in two ways:
- Local Installation: Install the CLI on your local computer.
- Cloud Shell: Use the browser-based Cloud Shell, accessible through the Google Cloud Console. Cloud Shell eliminates the need for local installation and offers features like a built-in code editor, 5 GB of persistent storage, and pre-installed tools. It supports various programming languages, including Python, Java, Node.js, and more.
For detailed instructions on installing GCP CLI on Windows or Linux, refer to resources such as “How to Install GCP CLI in Linux and Windows.”

3. Client Libraries

GCP also offers client libraries to simplify resource management and application development. These libraries provide language-specific APIs for intuitive interaction with GCP services. Examples include:

App APIs: Enable seamless integration with GCP services while minimizing code complexity.
Admin APIs: Facilitate resource management and are ideal for building automation tools.

These libraries can also be used with popular Google services like Google Maps, Drive, and YouTube, enhancing application functionality with minimal effort.

GCP Pricing and Free Tier

Google was the primary major Cloud provider to bill by the second instead of rounding up to greater units of your time for its virtual machines as a service offering. This may not sound like a big deal, but charges for rounding up can really add up for customers who are creating and running lots of virtual machines. Per second billing is obtainable for a virtual machine use through Compute Engine and for several other services too.

Compute Engine provides automatically applied use discounts which are discounts that you simply get for running a virtual machine for a big portion of the billing month. When you run an instance for at least 25% of a month, Compute Engine automatically gives you a reduction for each incremental minute you employ it. Here’s one more way Compute Engine saves you money.

Normally, you choose a virtual machine type from a typical set of those values, but Compute Engine also offers custom virtual machine types, in order that you’ll fine-tune the sizes of the virtual machines you use. That way, you’ll tailor your pricing for your workloads.

Free Tier: Google Cloud Platform offers a generous free tier with limited usage of various services, allowing users to explore and experiment with GCP without incurring charges. The free tier typically includes a certain amount of usage for services like Compute Engine, App Engine, Cloud Storage, BigQuery, and more.

GCP Open APIs and Avoiding Vendor Lock-in
