What is Cloud Computing?

Cloud computing is the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet ("the cloud") to offer faster innovation, flexible resources, and economies of scale. Instead of owning and maintaining physical data centers and servers, organizations can access technology services on an as-needed basis from cloud providers.

Types of Cloud Services

Cloud computing services are typically categorized into three main models:

  • Infrastructure as a Service (IaaS): Provides virtualized computing resources over the internet (e.g., AWS EC2, Google Compute Engine)
  • Platform as a Service (PaaS): Offers hardware and software tools over the internet (e.g., Heroku, Google App Engine)
  • Software as a Service (SaaS): Delivers software applications over the internet (e.g., Gmail, Salesforce, Office 365)

Major Cloud Providers

                        
// AWS Lambda Function Example
exports.handler = async (event) => {
    const response = {
        statusCode: 200,
        body: JSON.stringify({
            message: 'Hello from AWS Lambda!',
            timestamp: new Date().toISOString()
        }),
    };
    return response;
};

The leading cloud service providers include:

  • Amazon Web Services (AWS): Market leader with comprehensive services
  • Microsoft Azure: Strong enterprise integration and hybrid cloud solutions
