Chapter 1: The Cloud Computing Paradigm

Defining cloud computing and its key characteristics

Cloud computing is a paradigm that enables on-demand access to a shared pool of computing resources over the internet. It provides a flexible and scalable approach to computing, allowing users to access and utilize resources such as computing power, storage, and applications without the need for local infrastructure. Here are the key characteristics of cloud computing:

On-Demand Self-Service: Cloud computing offers self-service provisioning, allowing users to independently provision computing resources, such as virtual machines, storage, or software applications, as needed. Users can easily scale up or down their resource allocation based on their requirements.

Broad Network Access: Cloud services are accessible over the network, typically the internet, from a variety of devices such as laptops, desktops, smartphones, or tablets. This accessibility enables users to access their applications and data from anywhere, at any time.

Resource Pooling: Cloud providers consolidate and optimize computing resources, creating a multi-tenant environment where resources are shared among multiple users. These resources include processing power, storage, and network bandwidth. By pooling resources, cloud providers can achieve higher efficiency and economies of scale.

Rapid Elasticity: Cloud systems can quickly and automatically scale resources up or down based on the demand. This elasticity allows users to handle fluctuating workloads effectively. Resources can be added or removed dynamically, ensuring optimal performance and cost efficiency.

Measured Service: Cloud computing provides transparency and accountability through metering and monitoring mechanisms. Users are billed for the resources they consume, typically on a pay-per-use basis. Metering allows for accurate resource usage tracking, cost management, and optimization.

Service Models: Cloud computing offers different service models to cater to various needs:

Infrastructure as a Service (IaaS): Users have access to virtualized computing resources, including networks, storage, and servers. They can deploy and manage their applications and have control over the underlying infrastructure.

Platform as a Service (PaaS): Users can develop, deploy, and manage applications without the need to manage the underlying infrastructure. PaaS provides a preconfigured environment for application development, reducing the complexity of infrastructure management.
