What Is Cloud Computing Definition, Features and Its Advantages?
If we want to answer the main question of this article, “what is cloud computing” we have to say, it is one of the things that can be confusing in some cases. But it’s really not as confusing as it sounds. In fact, most people who say they don’t understand this concept are those who use cloud computing every day.
The cloud computing definition is a term used to describe the difference in how “computing” is served to users over the network (usually the Internet). So it is a model of computing that relies on a shared set of physical – or virtual – resources rather than dedicated resources for each user. In a way, cloud computing can also be termed a useful tool that drives users to use more resource-based but collaborative services rather than personalized services.
What Is Cloud Computing?
Do you know what is cloud solutions meaning or how it works? In general, the cloud is a substitute word for the Internet. If you look at the cloud scenario, you will see that this scenario is very similar to the scenario that users have to access the Internet and websites.
How Cloud Computing Works?
Cloud services include several important components that include:
- Front end platform: such as tablets (called thin clients) or mobile phones (called mobile clients) and laptops and pcs (called thick/fat clients).
- Back end platforms: Includes storage and servers
- Cloud-based Delivery: This section includes IaaS, SaaS, PaaS as well as DaaS.
- Network: The last and most important component of cloud computing services is the network. This network can be accessible to the public, such as the Internet, or only accessible to specific people, such as the internal network of organizations.
Cloud Computing Features
1- Broad Network Access
You can access from across the web using any device with internet connectivity. In this way, your cloud data will be accessible through web browsers, as well as on mobile devices or a laptop or. Cloud Computing’s underlying infrastructure provides users with servers on multiple locations.

Cloud Computing Types
The extensible models of cloud computing systems aside, we will get to their types of services. These models include:
- Infrastructure as a Service (IaaS)
- Platform as a Service (PaaS)
- Software as a Service (SaaS)
1- Infrastructure as a Service (Iaas)
Like all cloud computing services, this model also accesses computing resources in a simulated environment – the cloud – over a public connection (usually the Internet connection). In the case of IaaS, the computing resources provided are exactly the same as virtualized hardware. In other words: computing infrastructure, this description includes things like virtual server space, network communications, bandwidth, IP addresses, and load balancers. Physically, a coalition is made up of hardware from multiple servers, and networks are usually distributed across multiple datacenters, with the cloud service provider having to maintain all of them. On the other hand, the customer is given access to virtualized components so that they can create their own IT platform.
2- Platform as a Service (Paas)
PaaS is one of the types of cloud computing developing IaaS describing a category of cloud computing that provides the platform and environment for programmers to launch and create software and services over the Internet. PaaS services are hosted in the cloud and are easily accessible to users through Internet browsers. PaaS, a cloud service provider, allows users to create applications and software using the tools offered by the provider. PaaS services can include pre-configured features that subscribers can subscribe to and use. They can select features that meet their needs and discard features that are not useful to them.
3- Software as a Service (SAAS)
SaaS is one of the types of cloud computing that describes how to deliver software to the user. This software must be hosted in the cloud and can be used for a wide range of personal and organizational activities. Google, Twitter, and Facebook are all examples of SaaS that users can connect to via an Internet-enabled device. Users of organizations can also use software to meet wider needs such as accounting and payment, scheduling, performance monitoring, and communications (including email and messaging services).

There are also a variety of options to choose and use from cloud computing services, depending on your need for security, access to server management, and support that will satisfy almost any type of business:
The first is the public cloud model. In this service model, infrastructures are created by a cloud service provider outside your company that is accessible to the public from infrastructures such as the Internet. Public cloud services economically give you high scalability and stability, but keep in mind that cloud-based services (dedicated cloud services) for enterprise IT and business users to have access to the highest level.
Dedicated Cloud or Private Cloud Services provide you with a dedicated infrastructure service set up on a private – real or virtual – network that is viewable and accessible only by specific users. The clearest advantage is its high security and greater control. The economic benefits of this model fall victim to security.
The last cloud option is Hybrid cloud computing. As the name suggests, the service is a combination of both options. In such a way, those that require higher security are stored in the premium cloud service and those that are less sensitive are included in the public cloud services. In this case, it only costs more for important services.

What Are the Benefits of Cloud Computing?
One of the common questions among users is that what are the advantages of cloud computing? If we want to mention some of its advantages, we can come up with the list below:
1- Cost Savings
You can save up to 50% annually by moving virtualized operating system instances in the cloud. In fact, there is no need to buy a ton of external hard drives to keep your important information. Cloud allows access to professional staff, cutting-edge hardware, and software, and advanced security systems, which adds up to the projected savings. In the end, you will never have to spend money on services that you are not using.
Security of cloud computing includes a set of controls, policies, procedures, and technologies that work together to protect and save cloud-based data, systems, and infrastructure. These security measures are built to protect cloud data and support regulatory compliance. Also, they protect customers’ privacy as well as set authentication rules for individual users and devices.
The reason for this appealing security is the encryption of data being transmitted over networks and stored in databases. Encryption does not allow hackers or anyone not authorized to view or access your data.
