What is cloud computing?
Cloud computing generally, is the delivery of computing services such as servers, storage, databases, networking, software, analytics, and intelligence, over the Internet.
In cloud computing, the internet is referred to as the cloud.
The name cloud computing comes from the conventional usage of the cloud to represent the internet or a wide area network (WAN) in network diagrams or flowcharts.
Cloud computing allows for data to be accessed over the Internet rather than through a computer’s hard drive. That is why cloud computing is often thought of as an insurance policy should a computer break down or experience disastrous hard drive failure.
It allows multiple computers on a local network to access data and thus is used for everything from banking to data sharing.
The cloud is widely used and people spend a huge amount of money creating, managing and upgrading their cloud computing systems.
According to experts, the government is the largest user of the cloud in the world.
TYPES OF CLOUD COMPUTING
Cloud computing deployment models
A cloud deployment model is a “configuration” of certain cloud environment parameters such as the storage size, accessibility, and proprietorship. To choose the most suitable one for you, SaM Solutions recommends companies to make a choice based on their computing, networking, storage requirements, TCO expectations, and business goals, as well as available resources.
There are four main cloud deployment models that differ significantly and for which most of the companies opt: a public, private, hybrid and a community one. There are also web-based organization systems that are not so widespread, such as virtual private, inter-cloud and others.
This is a type of computing in which a third-party cloud service provider makes affordable computing resources available to the public via the internet. With public cloud services, users don’t need to purchase hardware, software or supporting infrastructure, all of which is owned and managed by providers.
Advantages of a public model
- Unsophisticated setup and use
- Easy access to data
- Flexibility to add and reduce capacity
- Continuous operation time
- 24/7 upkeep
- Eliminated need for software
Disadvantages of a public model
- Data security and privacy
- Compromised reliability
- The lack of individual approach
This refers to cloud computing resources used exclusively by a single business or organization. Private clouds, specifically, are used by the government in an attempt to maintain security and control over the cloud. It provides more control of resources and allows clients to steer clear of multitenancy.
Advantages of a private model
- Individual development
- Storage and network components are customizable
- High control over the corporate information
- High security, privacy, and reliability
It is very costly
A hybrid cloud is a form of computing which combines public and private clouds, bound together by technology that allows data and applications to be shared between them. It facilitates portability of data, apps and services and more choices for deployment models. It also helps optimize existing infrastructure, security, and compliance.
Importance of Hybrid Model
- Improved security and privacy
- Enhanced scalability and flexibility
- Reasonable price
Computing which utilizes various cloud services to drive innovation and aid business agility. It is the use of two or more cloud computing services.
A multicloud deployment model resembles a private one to a large extent; the only difference is the set of users. While a private type implies that only one company owns the server, in the case of a multi one, several organizations with similar backgrounds share the infrastructure and related resources.
This is a cloud computing model that helps people in saving their data securely on remote servers which can be accessed through the internet. A cloud service operator maintains, manages and operates it.

Types of Cloud Deployment Models: The Comparison
To facilitate the choice of the appropriate deployment models of cloud computing by opting for the ones with the most business-critical features, we have created a comparative table that provides an overall view of the specificity of each type.
