Cloud Computing.
Written by Stigg Security on Feb 09, 2023
This is a popular and rapidly growing area of IT that is relevant to businesses of all sizes.
Cloud computing is a model of delivering computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet to offer faster innovation, flexible resources, and economies of scale.
The cloud model is composed of five essential characteristics, three service models, and four deployment models.
The five essential characteristics of cloud computing are:
On-demand self-service: Consumers can provision computing resources as needed, without having to interact with a service provider.
Broad network access: Cloud services can be accessed over the network using a variety of devices, including laptops, smartphones, and tablets.
Resource pooling: Computing resources are dynamically assigned and reassigned according to consumer demand.
Rapid elasticity: Cloud services can be quickly scaled up or down to meet changing demand.
Measured service: Cloud services are monitored and metered, so that usage can be accurately tracked and billing can be based on actual usage.
The three service models of cloud computing are:
Infrastructure as a Service (IaaS): This model provides virtualized computing resources, including servers, storage, and networking, over the Internet.
Platform as a Service (PaaS): This model provides a platform for developing, running, and managing applications and services, without the need to manage infrastructure.
Software as a Service (SaaS): This model provides access to software applications over the Internet, without the need to install or run the software on local computers.
The four deployment models of cloud computing are:
Public cloud: This model provides computing resources over the Internet to the general public, owned and operated by a third-party service provider.
Private cloud: This model provides computing resources over a private network, for the exclusive use of a single organization.
Community cloud: This model provides computing resources over a shared network, for the exclusive use of a specific community of consumers.
Hybrid cloud: This model provides a combination of public and private clouds, allowing organizations to use the best of both worlds.
Cloud computing has revolutionized the way that organizations use and manage IT resources, providing greater flexibility, scalability, and cost-effectiveness
