Introduction to Cloud Computing

Welcome to the Introduction to Cloud Computing course at Skunkworks Academy! This course is designed to provide you with a comprehensive understanding of cloud computing concepts, models, and services.

🌟 Course Overview

In this course, you will learn:

• The basics of cloud computing
• Different cloud service models (IaaS, PaaS, SaaS)
• Cloud deployment models (Public, Private, Hybrid)
• Benefits and challenges of cloud computing
• Key cloud providers and their services

🖥️ Module 1: What is Cloud Computing?

Cloud computing is the delivery of computing services—including servers, storage, databases, networking, software, and analytics—over the internet (“the cloud”). Companies offering these computing services are called cloud providers.

Key Concepts

• **On-Demand Self-Service**: Users can provision computing resources as needed automatically.
• **Broad Network Access**: Services are available over the network and accessed through standard mechanisms.
• **Resource Pooling**: Provider’s computing resources are pooled to serve multiple users using a multi-tenant model.
• **Rapid Elasticity**: Capabilities can be elastically provisioned and released to scale rapidly.
• **Measured Service**: Cloud systems automatically control and optimize resource use by leveraging a metering capability.

🌐 Module 2: Cloud Service Models

Cloud computing services are typically classified into three models:

Infrastructure as a Service (IaaS)

• Provides virtualized computing resources over the internet.
• Examples: Amazon Web Services (AWS) EC2, Google Compute Engine, Microsoft Azure VMs.

Platform as a Service (PaaS)

• Offers hardware and software tools over the internet, typically those needed for application development.
• Examples: Google App Engine, AWS Elastic Beanstalk, Microsoft Azure App Services.

Software as a Service (SaaS)

• Delivers software applications over the internet, on a subscription basis.
• Examples: Google Workspace, Microsoft Office 365, Salesforce.

🏢 Module 3: Cloud Deployment Models

Cloud computing can be deployed in various models to meet different business needs:

Public Cloud

• Services are delivered over the public internet and shared across organizations.
• Examples: AWS, Google Cloud Platform, Microsoft Azure.

Private Cloud

• Computing resources are used exclusively by one business or organization.
• Example: Internal data centers.

Hybrid Cloud

• Combines public and private clouds, allowing data and applications to be shared between them.
• Example: Combining on-premises infrastructure with public cloud services.

📈 Benefits and Challenges of Cloud Computing

Benefits

• **Cost Savings**: Reduces capital expenditure.
• **Scalability**: Easy to scale resources up or down.
• **Accessibility**: Access services from anywhere with an internet connection.
• **Disaster Recovery**: Simplifies data backup and recovery.

Challenges

• **Security and Privacy**: Ensuring data protection.
• **Compliance**: Meeting regulatory requirements.
• **Downtime**: Potential for service outages.
• **Vendor Lock-In**: Difficulty in migrating from one cloud provider to another.

🏆 Key Cloud Providers

• **Amazon Web Services (AWS)**: A comprehensive and widely adopted cloud platform.
• **Microsoft Azure**: A growing collection of integrated cloud services.
• **Google Cloud Platform (GCP)**: A suite of cloud computing services that runs on the same infrastructure that Google uses internally.
