What is Google Cloud Platform (GCP)?

Google Cloud Platform (GCP) is a set of cloud services that lets you run applications, store and process data, and scale workloads without managing physical servers. It covers computing, storage, databases, analytics, and machine learning, all on Google’s global network.

For startup teams and small businesses, it means you can launch projects, experiment with new ideas, and handle traffic growth without hiring a large IT team. Resources can be scaled up or down as needed, so you only use what you need.

In this guide, we go through how GCP works, its key services, pricing, real-world use cases, and how it stacks up against other cloud platforms, so you can decide whether it’s the right fit for your business.

Understanding Google Cloud Platform (GCP)

Cloud computing changed how businesses run software. Instead of buying servers, setting up networks, and managing hardware, you can now access computing power, storage, and other services over the internet and pay for what you actually use.

Google Cloud Platform (GCP) is Google’s solution for business computing needs. While AWS has the largest market share and Azure integrates closely with Microsoft products, GCP leverages Google’s expertise in data analytics, machine learning, and global infrastructure.

GCP was launched in 2008 with App Engine, a platform for hosting web applications. Since then, it has grown into a full cloud platform used by startups and large enterprises. It runs on Google’s global infrastructure, which spans over 40 regions and more than 100 availability zones. This network handles billions of searches daily, providing the same reliability and performance to the applications running on GCP.

8. Integration with Google Services: GCP works smoothly with tools like Firebase, Workspace, and BigQuery, allowing teams to streamline workflows and leverage existing Google services efficiently.

9. Reliability and SLAs: GCP provides service-level agreements for key products, backed by its global infrastructure, giving teams confidence in uptime and operational continuity.

Key Components of Google Cloud Platform

GCP offers over 100 services, but most businesses use a core set depending on their needs. Here’s an overview of key components.

1. Compute Engine

Compute Engine is GCP’s infrastructure-as-a-service (IaaS) product. It lets you run virtual machines (VMs) in the cloud. You choose the machine type, operating system, and disk size.

It’s useful when you need full control over your environment like running a database server, batch processing jobs, or legacy applications that aren’t containerized.

VMs can scale up (vertical scaling) or out (horizontal scaling with managed instance groups). You pay only for what you use, and sustained use discounts lower costs automatically if a VM runs for more than 25% of a month.

2. App Engine

App Engine is a fully managed platform for deploying web applications and APIs. You upload your code (in Python, Node.js, Java, etc.), and GCP handles the infrastructure - scaling, patching, load balancing, and monitoring.

It’s ideal for startups or small teams that want to launch an app quickly without managing servers. App Engine scales automatically - from zero to thousands of users - and you only pay when your app is receiving traffic.

There are two environments: standard (more restrictive, faster scaling) and flexible (custom runtimes, longer startup times).

3. Cloud Run

Cloud Run is a serverless platform for running containerized applications. If you’re using Docker, you can deploy your container to Cloud Run without managing servers or clusters.

It scales from zero to thousands of instances automatically and charges only when your service is handling requests. This makes it cost-effective for microservices, background workers, or APIs with variable traffic.

Unlike Kubernetes Engine, Cloud Run abstracts away cluster management, so you get container flexibility without operational overhead.

4. BigQuery

BigQuery is GCP’s serverless data warehouse. You can run SQL queries on petabytes of data in seconds, without managing any infrastructure.

It’s designed for analytics, not transactional workloads. Use cases include business intelligence, log analysis, and customer behavior tracking. BigQuery integrates with Looker, Google Sheets, and third-party tools via standard connectors.

Pricing is based on data processed, not storage, so you can store large datasets cheaply and query only what you need.

5. Memorystore for Redis

Memorystore is a fully managed Redis service for in-memory caching and real-time data processing.

Use it to speed up applications by caching database queries, session data, or API responses. It supports Redis 5.0 and 6.0, offers high availability, and integrates with Compute Engine, App Engine, and Cloud Run.

Since it’s managed, Google handles failover, backups, and updates.

6. Persistent Disk

Persistent Disk provides reliable block storage for VMs in Compute Engine. It’s like a virtual hard drive that stays intact even if the VM restarts.

You can choose between standard (HDD) and balanced/provisioned SSD options based on performance needs. Disks can be attached or detached from VMs and resized without downtime.

Snapshots are incremental and stored in Cloud Storage, making backups efficient and durable.

7. Google Tensor Processing Unit (TPU)

TPUs are custom-built hardware accelerators designed by Google for machine learning workloads.

They deliver high performance for training and inference in deep learning models, especially with frameworks like TensorFlow. TPUs are available in different generations and configurations, from single devices to full pods for large-scale training

While not needed for most applications, TPUs give GCP an edge in AI research and production ML pipelines.
