The Internet is "the Cloud"

In a nutshell, cloud computing is the delivery of computing services over the Internet to offer servers, storage, databases, networking, software, analytics, and even, intelligence.

Companies typically use cloud services to lower operation costs, run more scalable IT infrastructure for growing and changing business needs because of its “pay per use” business nature.

There are three ways to deploy cloud services for an organization: on a private cloud, public cloud, or hybrid cloud.

Public Cloud

When deploying systems on a public cloud, the organization does not own and operate the computing resources such as servers, storage and network. Instead, they are owned, managed and operated by a third-party cloud service providers. Microsoft Azure and Amazon Web Services (AWS) are typic examples of a public cloud.

Private Cloud

When cloud computing resources are used exclusively by a single organization, it is known as a private cloud. A well-designed virtualization environment in an organization can also be seen as a private cloud.

Hybrid Cloud

A Hybrid cloud combines both public and private clouds, bound together by technology that allows data and applications to be communicated and shared between them. A hybrid cloud gives its users’ business greater flexibility, more deployment choices. It helps optimize existing infrastructure, security, and compliance when allowing data and applications to move between private and public clouds.

From the service point of view, we can categorize cloud services into four broad areas: infrastructure as a service (IaaS), platform as a service (PaaS), serverless computing, and software as a service (SaaS).

Infrastructure as a Service (IaaS)

IaaS is the most basic category of cloud computing services. A user rents IT infrastructure - servers and virtual machines (VMs), storage, networks, OSes - from a cloud provider on a pay-as-use basis.

Platform as a Service (PaaS)

PaaS refers to cloud computing services that supply an on-demand environment for developing, testing, delivering, and managing software applications. The purpose of PaaS is to make the job easier for developers to quickly create web or mobile apps, without the hassle of setting up or managing the underlying infrastructure of servers, storage, network, and databases needed for development.

Serverless Computing

Overlapping with PaaS, serverless computing’s focus is to build app functionality without managing the underlying servers and infrastructure required. The cloud provider handles the setup, capacity planning, and server management entirely. Serverless computing can be highly scalable and event-driven as it only uses resources when a specific need (function or trigger) happens.

Software as a Service (SaaS)

SaaS is a way of delivering software applications over the Internet, on-demand and typically on a subscription basis. Microsoft 365 (previously known as Office 365) is a good example. The SaaS providers host and manage the software application and underlying infrastructure, and handle any maintenance, like software upgrades and security patching. Users connect to the applications over the Internet, usually with a web browser on their devices, such as desktop computers, tablets, or mobile phones.
