Cloud Computing Overview

Web 1.0 is the first generation of the World Wide Web. It primarily focused on static websites with limited user interaction.

Web 2.0 is the second generation of the World Wide Web. It emphasizes user interaction, dynamic content, participation, and social media.

Web 2.0 features include user-generated content, dynamic content, collaboration, social media, and the use of JavaScript and AJAX.

Web 2.0 applications tend to have more interaction with the end user, allowing for more personalized experiences and community building.

Web 2.0 encourages the creation and sharing of content, allowing users to participate in the online world.

AJAX and JavaScript frameworks are used to create dynamic content and improve the user experience in Web 2.0.

Web 2.0 uses APIs to allow access to information and data for use by other applications.

The transition from Web 1.0 to Web 2.0 has shifted the way websites are used and designed, emphasizing interaction and collaboration.

The Semantic Web enables computers to understand the meaning of words, allowing for more advanced search and content sharing.

Web 3.0 leverages AI to make computers more intelligent, able to understand user needs and deliver better results.

3D graphics enhance websites and services in Web 3.0, offering immersive experiences for users.

Web 3.0 fosters interconnected information, enabling a smoother and more integrated online experience.

Web 3.0 encourages access to information from anywhere, anytime, making content universally available.

Distributed Ledger Technology (DLT) allows information to be shared across multiple devices, enhancing transparency and security.

Smart Contracts in Web 3.0 allow for automatic execution of agreements based on predefined conditions.

Web 3.0 focuses on sharing data, rather than owning it, empowering users to control their information.

A type of computing that uses multiple processing elements to solve problems simultaneously. This allows tasks to be broken down and completed concurrently, leading to faster execution.

The benefit of parallel computing that saves time and resources by allowing multiple processors to work on a task concurrently.

The reason why parallel computing is crucial for handling large and complex problems that would be impossible to solve using a single processor.

Parallel computing allows for efficient use of computing resources even when local resources are limited.

The use of a single processor to handle tasks sequentially.

A form of online communication that utilizes static web pages, providing non-interactive content.

An enhanced version of the web emphasizing interactivity and dynamic content, using technologies such as AJAX, JavaScript, CSS, and HTML.

The next generation of the web, focusing on semantic web technologies such as blockchain, artificial intelligence, and decentralized protocols.

A cloud computing platform layer that allows customers to outsource their IT infrastructure, including servers, networking, storage, and virtual machines, for a pay-as-you-go fee.

IaaS eliminates the need for individual organizations to maintain their own IT infrastructure, allowing them to scale their resources up or down based on demand.

IaaS can be deployed in three models: public, private, and hybrid.

Virtualization is a core concept in IaaS, allowing the creation of virtual machines that abstract physical resources like servers and storage.

IaaS allows users to dynamically scale their computing resources up or down based on demand, ensuring optimal performance and cost-effectiveness.

IaaS offers self-service portals, enabling users to independently deploy, manage, and monitor their resources, minimizing the need for IT staff intervention.

IaaS providers commonly use redundancy and geographically dispersed data centers to ensure high availability and reliability of services.

IaaS resource pooling allows users to share resources like storage and networking, which optimizes utilization and cuts overall costs.

A pricing model where users pay a fixed monthly or yearly fee for access to software, regardless of usage.

A pricing model where users pay based on their actual usage of the software, such as data processed or API calls.

Software applications offered by a third-party provider, enabling users to access and manage documents online.

Software-as-a-Service (SaaS) providers offer software without requiring users to manage infrastructure or maintenance.

SaaS providers offer various business services like ERP (Enterprise Resource Planning), CRM (Customer Relationship Management), billing, and sales.

SaaS companies provide collaboration tools for teams to work together effectively, regardless of location.

Social networking sites like Facebook and Twitter use SaaS to manage user data and handle unpredictable traffic.

SaaS enables email providers to handle fluctuating user loads and offer reliable email services.

A cloud computing model where a service provider offers hardware resources, such as servers, storage, and networking, to users over the internet. Users can access these resources on demand, without having to physically own or manage them.

A cloud computing model where a service provider offers a platform for developing, deploying, and managing applications. It includes operating systems, programming languages, databases, and other tools.

A cloud computing model where a service provider offers ready-to-use applications over the internet. Users can access these applications through a web browser or mobile device.

A cloud computing deployment model where resources are shared by multiple organizations. It is typically used by organizations with similar needs or interests.

A cloud computing deployment model where resources are owned and managed by a single organization. This model offers high levels of security and control over the data.

A cloud computing deployment model where resources are shared by multiple organizations. This model is typically used by organizations with specific needs or requirements that are not met by public or private cloud options.

A cloud computing deployment model where resources are provided by multiple cloud providers. This model offers flexibility, scalability, and redundancy.

A cloud computing deployment model where resources are provided by one or more cloud providers. This model offers flexibility, scalability, and redundancy.

The agreement between a cloud service provider and a customer that defines the level of service, performance, and support that the provider will provide.

The process of making decisions and taking actions related to cloud computing in a transparent and accountable manner. This includes involving stakeholders, making sure everyone understands the process, and addressing potential conflicts.
