Why Cloud Computing?

This document provides an overview of cloud computing, including definitions, history, deployment models, service models, how it works, pros and cons, and examples of real-life applications. Cloud computing relies on sharing computing resources over the internet rather than local hardware. It allows users to access software, platforms, and infrastructure virtually through pay-per-use models. Major types include infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS). The cloud symbol was used as early as 1977 and cloud computing has evolved significantly since the 2000s with offerings from Microsoft, Amazon, Google, and others.

he storing of data and applications on remote servers, and accessing them via the internet rather than saving and installing them on your personal or office computer. The term cloud is used because data or applications are stored in cloud or collection of web servers. The cloud can be accessed using cloud computing interface software or using a web based service. Infrastructure as a service(IaaS). Platform as a service(PaaS). Software as a service(SaaS).

Cloud computing allows users to access computing resources like data storage, servers, databases, networking, software, analytics and more without direct interaction with the underlying infrastructure. It provides services through three main models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). IaaS provides on-demand access to virtualized computing resources. PaaS provides a platform and solutions stack. And SaaS provides software applications delivered through a browser. Common advantages of cloud computing include pay per use, instant scalability, security, reliability and APIs.

Cloud computing uses remote servers and the internet to maintain data and applications. It provides benefits like reduced costs, flexibility, and collaboration capabilities. Cloud computing delivers on-demand IT resources and applications from external providers via internet technologies in various forms including Platform as a Service (PaaS), Infrastructure as a Service (IaaS), and Software as a Service (SaaS). Cloud structures can be private, public, or hybrid depending on the needs and resources of an organization.

This document provides study material for the AZ-900 Azure Fundamentals exam. It lists links to Microsoft documentation on various Azure services and components that are covered in the exam, including Azure regions, resource groups, compute services, storage, databases, analytics, artificial intelligence, serverless computing, and management tools. The links are organized under headings that align with the topics and modules in the Skylines Academy AZ-900 course.

This document provides an overview of cloud computing. It defines cloud computing as internet-based computing where software, storage, and applications are delivered through the internet. The document outlines the cloud computing architecture and three main service models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). It also discusses the advantages of cloud computing in providing powerful and accessible computing resources at lower costs, while allowing for collaborative work. Types of cloud storage including public, private, and hybrid clouds are also introduced.
