Cloud Computing, AI & ML – Complete Tutorial

1. Introduction to Cloud Computing, AI & ML

What is Cloud Computing?

Cloud computing delivers computing services (servers, storage, databases, networking, AI, analytics) over the Internet ("the cloud").

✅ Key Benefits:
✔ Scalability (grow as needed)
✔ Cost-Efficiency (pay-as-you-go)
✔ Global Availability (access from anywhere)

What is AI & Machine Learning (ML)?

• Artificial Intelligence (AI): Machines mimicking human intelligence.

• Machine Learning (ML): AI subset where machines learn from data without explicit programming.

✅ Key Applications:
✔ AI: Chatbots, self-driving cars, recommendation systems.
✔ ML: Fraud detection, medical diagnosis, stock predictions.

2. Cloud Computing Basics

Cloud Service Models

Service Model	Description	Example
IaaS (Infrastructure as a Service)	Provides virtualized computing resources (servers, storage)	AWS EC2, Azure VMs
PaaS (Platform as a Service)	Provides a platform for app development & deployment	Google App Engine, Heroku
SaaS (Software as a Service)	Delivers software applications over the Internet	Gmail, Slack, Zoom

Cloud Deployment Models

• Public Cloud (AWS, Azure, GCP)

• Private Cloud (On-premises cloud)

• Hybrid Cloud (Mix of public & private)

Getting Started with AWS (Example)

1. Sign up for AWS Free Tier (aws.amazon.com)

2. Launch an EC2 Instance (Virtual Server)

   • Choose OS (Ubuntu, Windows)

   • Select instance type (t2.micro for free tier)

   • Configure security groups (allow SSH/HTTP)

3. Connect via SSH

   sh

   Copy

   Download

   ssh -i key.pem ubuntu@<public-ip>

3. Machine Learning (ML) Fundamentals

Types of Machine Learning

Type	Description	Example
Supervised Learning	Learns from labeled data (input-output pairs)	Spam detection
Unsupervised Learning	Finds patterns in unlabeled data	Customer segmentation
Reinforcement Learning	Learns by trial & error (rewards/punishments)	Game AI (AlphaGo)

Popular ML Algorithms

• Regression: Predicts continuous values (e.g., house prices)

• Classification: Categorizes data (e.g., spam vs. not spam)

• Clustering: Groups similar data (e.g., customer segments)

ML Workflow

1. Data Collection (Kaggle, APIs, databases)

2. Data Preprocessing (cleaning, normalization)

3. Model Training (using algorithms like Linear Regression, Decision Trees)

4. Evaluation (accuracy, precision, recall)

5. Deployment (cloud, edge devices)

4. AI & ML on the Cloud

Why Use Cloud for AI/ML?

✔ Access to GPUs/TPUs (faster training)
✔ Managed ML Services (no infrastructure setup)
✔ Scalability (handle large datasets)

Top Cloud AI/ML Services

Cloud Provider	AI/ML Service	Use Case
AWS	SageMaker	Build, train, deploy ML models
Google Cloud	Vertex AI	End-to-end ML pipeline
Microsoft Azure	Azure ML	Drag-and-drop ML studio

Example: Deploying an ML Model on AWS SageMaker

1. Upload dataset to S3

   python

   Copy

   Download

   import boto3
   s3 = boto3.client('s3')
   s3.upload_file('data.csv', 'my-bucket', 'data.csv')

2. Train a Model

   python

   Copy

   Download

   from sagemaker import LinearLearner
   estimator = LinearLearner(role='SageMakerRole',
                            instance_count=1,
                            instance_type='ml.m4.xlarge')
   estimator.fit({'train': 's3://my-bucket/data.csv'})

3. Deploy for Predictions

   python

   Copy

   Download

   predictor = estimator.deploy(initial_instance_count=1,
                               instance_type='ml.t2.medium')
   result = predictor.predict([1.5, 3.2, 5.1])  # Example input

5. AI-as-a-Service (AIaaS)

Cloud providers offer pre-trained AI models via APIs:

Service	Function	Example
AWS Rekognition	Image & video analysis	Face detection
Google Vision AI	OCR, object detection	Text extraction
Azure Cognitive Services	Speech, language, vision	Sentiment analysis

Example: Using AWS Rekognition (Python)

python

Copy

Download

import boto3

client = boto3.client('rekognition')
response = client.detect_labels(
    Image={'S3Object': {'Bucket': 'my-bucket', 'Name': 'photo.jpg'}}
)
print(response['Labels'])  # Outputs detected objects

7. Hands-On Project: Cloud-Based Sentiment Analysis

Step 1: Set Up Google Cloud Natural Language API

1. Enable Google Cloud Natural Language API.

2. Install the client library:

   sh

   Copy

   Download

   pip install google-cloud-language

3. Run sentiment analysis:

   python

   Copy

   Download

   from google.cloud import language_v1
   
   client = language_v1.LanguageServiceClient()
   text = "I love cloud computing and AI!"
   document = language_v1.Document(content=text, type_=language_v1.Document.Type.PLAIN_TEXT)
   sentiment = client.analyze_sentiment(request={'document': document}).document_sentiment
   print(f"Sentiment: {sentiment.score} (Magnitude: {sentiment.magnitude})")

Step 2: Deploy as a Cloud Function

1. Go to Google Cloud Functions.

2. Deploy the Python code as an HTTP-triggered function.

3. Call it via a REST API.
