Google Cloud Platform (GCP) is one of the world's leading cloud computing platforms. Built on the same infrastructure that Google uses for its own products — including Search, Gmail, YouTube, and Google Maps — GCP offers a comprehensive suite of cloud services spanning compute, storage, databases, networking, machine learning, data analytics, and developer tools.
Cloud computing is the delivery of computing resources — servers, storage, databases, networking, software, and analytics — over the internet ("the cloud"). Instead of purchasing and maintaining physical hardware, organisations rent access to these resources from a cloud provider on a pay-as-you-go basis.
There are three primary service models in cloud computing:
| Model | Description | Example |
|---|---|---|
| IaaS (Infrastructure as a Service) | You rent virtual machines, storage, and networks. You manage the OS upwards. | Compute Engine |
| PaaS (Platform as a Service) | The provider manages the OS and runtime. You deploy your code. | App Engine |
| SaaS (Software as a Service) | The provider delivers the full application. You consume it. | Google Workspace |
These three models represent different levels of abstraction. IaaS gives you maximum control, SaaS gives you minimum management overhead, and PaaS sits in between.
Google Cloud Platform is Google's public cloud offering. It was launched in 2008 with the introduction of App Engine, a platform for building and hosting web applications. Over the years, GCP has expanded dramatically and now offers over 200 products and services across virtually every category of cloud computing.
Key facts about Google Cloud:
Organisations choose Google Cloud for a variety of reasons:
Google Cloud is widely recognised as the leader in data analytics and big data. BigQuery, Google's serverless data warehouse, can analyse petabytes of data in seconds. The platform also offers Dataflow (stream and batch processing), Dataproc (managed Hadoop/Spark), and Looker (business intelligence).
Google is a pioneer in artificial intelligence. GCP provides Vertex AI for building and deploying ML models, pre-trained APIs for vision, language, and speech, and access to TPUs (Tensor Processing Units) — custom hardware designed for machine learning workloads.
Google created Kubernetes, the industry-standard container orchestration platform. Google Kubernetes Engine (GKE) is widely considered the most mature and feature-rich managed Kubernetes service available.
Google Cloud embraces open-source technologies and actively supports multi-cloud and hybrid-cloud strategies. Anthos allows you to manage workloads across GCP, on-premises, and other clouds (AWS, Azure) using a consistent platform.
Google operates one of the largest and most advanced private networks in the world. Traffic between GCP regions travels over Google's private fibre-optic backbone, reducing latency and increasing security compared to routing over the public internet.
GCP organises its 200+ services into broad categories:
| Category | Examples |
|---|---|
| Compute | Compute Engine, App Engine, Cloud Functions, GKE, Cloud Run |
| Storage | Cloud Storage, Persistent Disk, Filestore |
| Networking | VPC, Cloud Load Balancing, Cloud CDN, Cloud Interconnect, Cloud DNS |
| Databases | Cloud SQL, Cloud Spanner, Firestore, Bigtable, AlloyDB |
| Data Analytics | BigQuery, Dataflow, Dataproc, Pub/Sub, Looker |
| AI & Machine Learning | Vertex AI, AutoML, Vision AI, Natural Language AI, TPUs |
| Security | IAM, Cloud KMS, Security Command Center, BeyondCorp Enterprise |
| DevOps | Cloud Build, Artifact Registry, Cloud Deploy, Cloud Source Repositories |
| Management | Cloud Console, Cloud Shell, Cloud Monitoring, Cloud Logging |
You do not need to learn every service. This course focuses on the foundational concepts that underpin all of them.
This course covers ten key areas of GCP fundamentals:
Google Cloud Platform is a comprehensive cloud platform built on the same infrastructure that powers Google's own products. It excels in data analytics, machine learning, Kubernetes, and open-source technologies. With a global presence spanning 40+ regions and a commitment to multi-cloud strategies, GCP is trusted by organisations of all sizes — from startups to Fortune 500 companies. In the lessons that follow, you will learn the foundational concepts you need to navigate Google Cloud confidently.
