Google Cloud Platform (GCP) Tutorial

Overview

Google Cloud Platform (GCP) is a suite of cloud computing services provided by Google. It includes a range of services for computing, storage, databases, machine learning, and networking. GCP enables businesses to scale and innovate using Google's infrastructure.

Introduction to GCP

What is Google Cloud Platform?

Google Cloud Platform is a suite of cloud computing services offered by Google. It provides a range of services including computing power, storage, and big data analytics, all of which are hosted on Google's infrastructure.

Key Features

Scalability: Automatically scales resources based on demand.
Global Reach: Data centers around the world for low-latency access.
Security: Robust security features and compliance certifications.
Integration: Easy integration with other Google services and third-party tools.

GCP Services

Compute Services

Google Compute Engine: Scalable virtual machines running in Google’s data centers.
Google App Engine: Platform-as-a-Service (PaaS) for building and deploying applications.
Google Kubernetes Engine (GKE): Managed Kubernetes service for container orchestration.

Storage Services

Google Cloud Storage: Object storage for unstructured data.
Google Cloud Filestore: Managed file storage for applications.
Google Persistent Disk: Block storage for Google Compute Engine.

Database Services

Google Cloud SQL: Managed relational database service.
Google Cloud Firestore: NoSQL document database for web and mobile apps.
Google Bigtable: Managed NoSQL database for large analytical and operational workloads.

Networking Services

Google Cloud VPC: Virtual Private Cloud for network management.
Google Cloud Load Balancing: Distributes traffic across multiple instances.
Google Cloud CDN: Content Delivery Network for low-latency content delivery.

Google Compute Engine

Creating a Virtual Machine

Google Compute Engine allows you to create and manage virtual machines in the cloud.

Example: Creating a VM using gcloud CLI

gcloud compute instances create my-instance \
  --zone=us-central1-a \
  --image-family=debian-9 \
  --image-project=debian-cloud \
  --machine-type=n1-standard-1

Google Cloud Storage

Storing and Retrieving Data

Google Cloud Storage provides scalable object storage for unstructured data.

Example: Uploading a File

gsutil cp local-file.txt gs://my-bucket/

Example: Downloading a File

gsutil cp gs://my-bucket/remote-file.txt local-directory/

Google Cloud SQL

Managing a Relational Database

Google Cloud SQL is a managed database service for SQL databases.

Example: Connecting to Cloud SQL

gcloud sql connect my-instance --user=root

Example: Creating a Database

CREATE DATABASE mydatabase;

Google Cloud Functions

Creating Serverless Functions

Google Cloud Functions allows you to run code in response to events without managing servers.

Example: Deploying a Function

gcloud functions deploy my-function \
  --runtime python39 \
  --trigger-http \
  --allow-unauthenticated

Example: Function Code (Python)

def hello_world(request):
    return "Hello, World!"

Google Kubernetes Engine (GKE)

Managing Kubernetes Clusters

Google Kubernetes Engine provides a managed Kubernetes service.

Example: Creating a GKE Cluster

gcloud container clusters create my-cluster \
  --zone us-central1-a

Example: Deploying an Application

kubectl create deployment my-app --image=gcr.io/my-project/my-app
kubectl expose deployment my-app --type=LoadBalancer --port 80

Google Cloud Pub/Sub

Messaging and Event Handling

Google Cloud Pub/Sub is a messaging service for building event-driven systems.

Example: Creating a Topic

gcloud pubsub topics create my-topic

Example: Publishing a Message

gcloud pubsub topics publish my-topic --message "Hello, Pub/Sub!"

Google Cloud Networking

Managing Virtual Networks

Google Cloud Networking services help manage network resources.

Example: Creating a VPC Network

gcloud compute networks create my-network \
  --subnet-mode=auto

Example: Creating a Firewall Rule

gcloud compute firewall-rules create allow-ssh \
  --network my-network \
  --allow tcp:22

Google Cloud SDK

Using the Cloud SDK

The Google Cloud SDK provides command-line tools for managing GCP resources.

Example: Installing Cloud SDK

curl https://sdk.cloud.google.com | bash
exec -l $SHELL
gcloud init

Example: Listing Projects

gcloud projects list
