What Is Cloud Computing?

The term “cloud computing” describes providing various services through remote servers on the internet. Resources like software, servers, and data storage are all examples.

Cloud-based storage allows off-site backup instead of storing data on a conventional hard drive or other on-premises medium. If a computer or mobile device can connect to the internet, it can access information and applications.

Cloud computing has several business benefits, including higher productivity, faster processing times, better overall performance, and increased safety.

What is Cloud Computing Architecture?

Cloud computing architecture and infrastructure is the arrangement of cloud components in which shared computing resources get pooled and made available via a network using virtualization technologies. They include:

  • Front end
  • Back end
  • Delivery via the cloud
  • A network

These tools work together to form an infrastructure for cloud computing on which users’ applications can operate, unlocking the potential of cloud computing for their benefit.

Components of Cloud Computing Architecture

Cloud computing architecture has two main components.

1.Front End

A client interacts with the front end. It has the user interfaces and client-side software needed to connect to cloud-based services. The front end comprises the following:

  • Safari
  • Brave
  • Chrome
  • Bing
  • Mobile devices
  • Clients

2.Back End

Providers use the back end of their operations. It manages everything that must function to provide cloud computing services.

It comprises:

  • Servers
  • Security measures
  • An extensive database
  • Virtual machines
  • Traffic control systems
  • Deployment models, and more.

3.Client Infrastructure

The front end’s client infrastructure section gives users a graphical interface to connect with the cloud. The cloud computing infrastructure comprises all the components of conventional data centers, such as networking equipment, servers, and persistent storage.


Application development cloud computing can be any software or mobile app that a company provides to its clients to facilitate their access to the cloud.


When a client uses a cloud service, the provider manages that service for him. What are the tools used in cloud computing and categories of cloud services?


IaaS is a standard way to gain remote access to computing resources on demand. The architecture is ideal for building and delivering virtualized infrastructure resources like networks, data centers, storage systems, etc.

The cost of using an IaaS provider is proportional to the time and resources used. The provider ensures the users can access the amount and quality of resources they’ve promised. Examples of IaaS in cloud computing include Microsoft Azure and Amazon Web Services (AWS).


PaaS is an online service that allows developers to build and release software without managing infrastructure or solving dependencies. Users can configure different hosting and development pipelines to develop and test their products. Examples of PaaS in cloud computing that provide SaaS include Microsoft Azure and Google App Engine.


SaaS allows you to use software online, but the service provider does the software’s upkeep rather than your company.

Pricing for SaaS depends on factors such as the size of the user base, the amount of data stored, and the frequency of transactions. SaaS in cloud computing applications like Dropbox and Salesforce are good examples.

6.Runtime Cloud

Runtime cloud is a popular approach where services are easily accessible. It’s pretty similar to a cloud-based OS, which uses virtualization and provides users access to a vast array of networked servers.

Although they’re supported by virtualization technology, each of these servers functions independently as a storage drive, and together they comprise the central server or hypervisor. Notable hypervisors include Oracle VirtualBox, VMWare Fusion, and many others.


The storage service in cloud computing allows users to keep and manage their data on the cloud. In cloud computing storage, several clients can access the data simultaneously, usually by allocating a specific section of cloud storage for the task at hand.

To facilitate the operation of many services on a single OS, partitioning software in a cloud computing system allocates the capacity of these two resources in logical chunks.


The term “infrastructure” refers to the underlying framework that drives all cloud-based software services. It’s an umbrella phrase for a wide range of computing components, including the:

  • Network interface cards
  • Graphics processing unit (GPU)
  • Motherboard
  • Accelerator card
  • Central processing unit (CPU)

The cloud computing infrastructure model you select must consider the client workload.


The ’middleware’ of a cloud computing system is management software. If your organization has multiple fronts, this software can ensure each gets the attention and resources needed.

10. Hypervisor

Another term for the hypervisor is “Virtual Machine Monitor.” It includes the software, hardware, and technology necessary to develop and administer virtual servers. A VOP, or Virtual Operating Platform, is what the hypervisor shows the user.

It facilitates control of the guest OS in the cloud. Kernel is another common name for the operating system.

11. Security

Safety is essential, and one consideration while designing an architect’s security framework is monitoring and recording errors. Each day, you must fix bugs.

Backing up your system regularly is essential because it serves no purpose if you cannot restore data when needed. Firewall applications are necessary for a fully functional security infrastructure.

You may ask, what are the security risks of cloud computing? The cloud can become compromised by cybercriminals.

12. Internet

The internet serves as the networking tool between the frontend and backend components. Employing a cloud-based solution allows businesses to operate on reduced budgets and do away with on-site infrastructure. The widespread adoption of cloud computing results from its benefits, which impact production, innovation, and sales.

13. Virtualization

Although the terms are often used interchangeably, virtualization and cloud computing differ.

In cloud computing, virtualization refers to the digital representation of a physical computing resource, such as a server or other hardware. Multiple virtual machines can share the resources of a single physical server.

There are benefits of virtualization in cloud computing. For example, if a server serves multiple users, the virtualization software can provide each user with a unique identifier for the virtualized version of the server’s physical resources. It ensures the privacy and confidentiality of each client’s data by keeping it isolated from other customers.

Virtualization vs. cloud computing difference is that virtualization simulates a computer’s hardware and software components. In cloud computing, resources get pooled and made readily available to multiple users.

Benefits of Cloud Computing Architecture

There are many benefits of cloud computing architecture, including:

  • Businesses gain a competitive edge from the cloud’s scalability since it allows them to expand or decrease their use of cloud resources
  • It facilitates convenient user access on how to use cloud computing
  • Hackers have fewer targets to go after because there are fewer places for them to hack into
  • Increased mobility allows teams to be more effective and productive while working remotely
  • Updates to services happen automatically. It eliminates the need for you to keep updating it manually.
  • Other benefits of cloud computing for small businesses include getting rid of lag time, enhancing data processing needs, reducing IT operating expenses, and making data and digital tools readily available
  • Cloud architecture simplifies the entire cloud computing system

How Does Cloud Computing Architecture Work- Cloud Models

How well a cloud computing architecture serves your needs depends mainly on the cloud service you employ. That said, there are four types of cloud computing architecture models from which a customer can choose based on their particular business’s requirements:

Public Cloud

One common application of this cloud is business-to-consumer communication. In this setup, the computing resource gets operated and governed by a private company, university, or government agency.

Private Cloud

Here, only one particular organization is the target of the deployment of computing resources. It’s the primary means of communication used within the company.

Hybrid Cloud

It’s a commercial structure that can facilitate various exchanges, including those between companies and their clients or between companies themselves. The term “hybrid cloud” refers to the deployment approach that combines multiple cloud services to provide a unified pool of computing resources.

Community Cloud

Here, the computer power benefits nonprofits and other groups serving the public good.
