Overview
Cloud service refers to obtaining services on demand over a network in an easily scalable way. Cloud services can be IT and software, internet-related, or other types of services. It means that computing power can also be circulated as a commodity over the internet. Cloud services are based on the addition, use, and interaction models of internet-related services, typically providing dynamically scalable and often virtualized resources over the internet.Cloud computing represents another major shift after the client-server transformation of the 1980s.
Cloud computing is the result of convergence and evolution of traditional computer and network technologies, including Distributed Computing, Parallel Computing, Utility Computing, Network Storage Technologies, Virtualization, Load Balancing, and Content Delivery Networks.
The term "cloud" is a metaphor for networks and the internet. In the past, diagrams often used a cloud symbol to represent telecommunications networks, and later it was also used to represent the internet and the abstraction of underlying infrastructure.

Characteristics:
By distributing computing across a large number of distributed computers rather than local computers or remote servers, the operation of enterprise data centers becomes more similar to the internet. This allows enterprises to switch resources to the applications they need and access computer and storage systems on demand.
It's like moving from the old single-generator model to centralized power generation by a utility plant. It means computing power can also be circulated as a commodity — as convenient to use and as low-cost as gas, water, or electricity. The biggest difference is that it is delivered over the internet.
Forms: Public Cloud and Private Cloud
Simply put, cloud services put the software, hardware, and data needed by a business onto the network. They allow different IT devices to connect at any time and from any location, enabling data access and computing. Currently, common cloud services include Public Cloud and Private Cloud.
As enterprises deepen their adoption of cloud services, new demands continue to emerge in areas such as service forms, platform performance, data security, and construction costs. As a result, a new deployment model — Managed Cloud — has emerged alongside traditional public and private cloud offerings.
With Managed Cloud, enterprises can prioritize data security and low-latency access through localized deployments, gaining lightweight, dedicated cloud resources. Through managed operations, maintenance, and security services, enterprises can achieve a "light-asset, light-operations, high-security" model for adopting and using cloud services.
