Getting Started with Cloud Computing
Cloud computing has revolutionized the way we build and deploy applications. Whether you're a seasoned developer or just starting out, understanding cloud fundamentals is essential in today's tech landscape.
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.
Key Cloud Service Models
Infrastructure as a Service (IaaS) provides virtualized computing resources over the internet. Examples include AWS EC2, Google Compute Engine, and Azure Virtual Machines.
Platform as a Service (PaaS) provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining infrastructure. Examples include Heroku, Google App Engine, and AWS Elastic Beanstalk.
Software as a Service (SaaS) delivers software applications over the internet, on a subscription basis. Examples include Google Workspace, Salesforce, and Microsoft 365.
