In our last tutorial, we discussed the best Cloud Computing Tutorial. Here, we will explore Cloud Computing architecture with diagram and example. Moreover, we will learn important components of Cloud Computing architecture and some cloud-based delivery like Saas, PaaS, IaaS.

So, let’s start Cloud Computing Architecture.

Cloud Computing Architecture

Cloud Computing is an emerging technology which is skyrocketing nowadays. This technology is often used by big companies as well as the startups as it is flexible for both.

Every company is in need to store the data so they require cloud to store their information. The data is secured and can access anytime and from anywhere.

Cloud Computing architecture basically comprises of the two parts. They are the front-end and the back-end. The front end is the end which uses by the user and the back-end manages by the host. Both the end connects to each other with the means of internet.

Do you know How Cloud Computing Works?

i. Front End

The front end is the client part of Cloud Computing which uses as per the requirement of the user. Front-end comprises of the applications and the interfaces which help to access the cloud computing. Example- Browser or an app created by the company itself.

ii. Back End

The back end is a part which manages by the allotted authorities of the company and their back end has large data storage facilities, Virtual machines, security system, and servers. They are also engaged in traffic management along with security management.

Components of Cloud Computing Architecture

Let’s discuss some components of Cloud Computing Architecture:

Components of Cloud Computing Architecture

Components of Cloud Computing Architecture

i. Hypervisor

The hypervisor is also known as Virtual Machine Monitor. This consists of the software, hardware, and firmware which makes and runs the virtual machines. The Hypervisor provides a user with a platform which is known as Virtual Operating Platform.

This allows us to manage the guest’s operating system to use the cloud. This can be also known as the traditional term of the kernel in an operating system.

ii. Management Software

Management software consists of various plans and the strategies which help to increase the performance of the cloud. This management software provides many features such as on-time delivery of storage, proper security, all-time access, and many other facilities.

This is one of the important parts of Cloud Computing architecture. One of the important features of this is the compliance auditing, management of overseeing disaster, and contingency plans.

iii. Deployment Software

Cloud deployment simply means to initiate the working of the SaaS, PaaS, and IaaS. This initiates the solutions that can access by the users or the customers.

This deployment consists of all the mandatory installations and configurations of the cloud. This emerges from the back end and implements before the provisioning occurs.

iv. Route of Connectivity

It is an important part of the Cloud Computing architecture, through which the whole cloud gets connected. The speed of transfer depends on the network which is the internet connection.

There are many cloud servers present which connects with the help of this virtual route. This also provides a facility to the user by allowing them to customize the route and protocol.

v. A server of the Cloud

A cloud server is a virtual server running in cloud computing premises. It’s engineered, hosted and delivered via a cloud computing platform via the web. It can be accessed from anywhere.

Cloud servers are stable, quick and secured. They avoid the hardware problems seen with physical servers, and that they are seemingly to be the foremost stable choice for businesses. Also, call as virtual servers.

Cloud servers have all the software they need to run and can operate as non-dependent units. It also has the profit because it is incredibly simple and fast to upgrade by adding memory and disk space, further as being more cost-effective.

vi. Storage of the Cloud

Cloud storage service, construct to produce applications, services and organizations with access to offsite storage capability that may provision instantly are versatile in scaling automatically at runtime and is globally accessible.

An Infrastructure as a Service (IaaS) service model delivers scalable, flexible and redundant storage capability through net services API, online interfaces and thin client applications.

Cloud Storage also benefits the user by providing remote access with the help of internet. The storage services are very quick to access. Cloud information is often held on, altered and retrieved from a remote cloud storage server over the web below a utility computing model.

Cloud-Based Delivery

Cloud-Based delivery includes three major types they are-

Cloud Computing Architecture - Delivery

Cloud Computing Architecture – Cloud-Based Delivery

i. SaaS

SaaS stands for Software as a service where the cloud provider provides software with the help of internet.

It is scalable and provides a benefit that the system administrators can upload the applications to each of their own servers. The customers using SaaS can also access the application without installing the software.

ii. IaaS

IaaS stands for Infrastructure as a service. This means that taking the physical hardware and providing the virtual services. In this, there are businesses which pay the fee to run virtual servers, network, and storage from the cloud. This infrastructure maintains by the back end.

iii. Paas

PaaS stands for Platform as a service in this the third party provider delivers hardware and software tools. This basically benefits those who are need of application development.

The host providing this service provides the hardware and software on its own. This benefits the user by not installing the software at their premises.

So, this was all about Cloud Computing Architecture Tutorial. Hope you liked our explanation,


The architecture of the cloud is simple and lucid which clearly states the components embedded in it. This service is very economical and one can start using it for free.

The entire cloud computing architecture has the abilities to provide higher bandwidth which allows the user to access the cloud anytime. Furthermore, if you have any query/doubt? Feel free to ask in the comment section.
