Introduction to Cloud Computing

What is Cloud Computing?

Cloud computing is the delivery of computing services—such as 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 their own computing infrastructure or data centers, companies can rent access to anything from applications to storage from a cloud service provider.

Types of Cloud Computing

Cloud computing can be categorized into three main types:

• Infrastructure as a Service (IaaS): Provides virtualized computing resources over the Internet. Example: Amazon Web Services (AWS) EC2.
• Platform as a Service (PaaS): Provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure. Example: Google App Engine.
• Software as a Service (SaaS): Delivers software applications over the Internet, on a subscription basis. Example: Microsoft Office 365.

Benefits of Cloud Computing

Cloud computing offers several advantages, including:

• Cost Efficiency: Reduces the cost of managing and maintaining your IT systems.
• Scalability: Easily scale resources up or down as needed.
• Performance: Regularly updated services provide high-performance computing resources.
• Security: Many cloud providers offer advanced security features that guarantee data is securely stored and handled.
