Introduction To Cloud Computing Architecture

Cloud Computing, which is currently one of the most in-demand technologies, gives every organization a new shape by providing on-demand virtualized services/resources. From small to medium to large, every firm uses cloud computing services to store information and access it from anywhere and use only the internet. We shall learn more about cloud computing’s internal architecture in this post.

Transparency, scalability, security, and intelligent monitoring are just a few of the critical restrictions that any cloud infrastructure should face. The current study into other significant constraints assists cloud computing systems in developing new features and tactics that can provide more advanced cloud solutions.

What is Cloud Computing, and how does it work?

Internet based services like storage, software, analytics and databases are collectively called cloud computing. It involves all the services that can be delivered without being physically near the hardware qualifications. Netflix, for example, employs cloud computing to provide video streaming services. G suite is another such example of a cloud computing service. 

Cloud computing, expressed, is the distribution of on-demand resources (such as a server, database, software, and so on) over the internet. It also enables the creation, design, and management of cloud-based applications. You can learn more by taking up a few Cloud Courses online. 

A mix of event driven and service oriented architecture make up the cloud computing. The architecture of cloud computing is separated into two parts:

Back End

The service provider uses the back end. It oversees all of the resources needed to deliver cloud computing services. It includes a massive quantity of data storage and security measures, virtual machines, deployment models, servers, and traffic management mechanisms, among other things. 

  1. An application is a piece of software or a platform that a client can use in the back end. That is, it delivers the service at the back-end in accordance with the client’s needs.
  2. Back-end service refers to the three major categories of cloud-based services: SaaS, PaaS, and IaaS. It also controls which services the user has access to.
  3. Runtime Cloud – In the back-end, runtime cloud refers to providing an execution and runtime platform/environment to the virtual machine.
  4. Storage – Storage in the back-end refers to the provision of a flexible and scalable storage solution and data administration.
  5. Infrastructure – In the back-end, cloud infrastructure refers to the hardware and software components of the cloud, such as servers, storage, network devices, virtualization software, and so on.
  6. Back-end management refers to the administration of back-end components such as applications, services, runtime clouds, storage, infrastructure, and other security methods.
  7. Back-end security refers to installing various security techniques in the back-end to provide secure cloud resources, systems, data, and infrastructure to end-users.
  8. Internet – An Internet connection serves as a medium or a bridge between the front-end and the back-end, allowing them to interact and communicate.

Front End

The client interacts with the front end. It includes client-side interfaces and applications for interacting with cloud computing services. Web servers (such as Chrome, Firefox, and Internet Explorer), thin and fat clients, tablets, and mobile devices make up the front end.

For instance, to access the cloud platform, you may utilize a web browser.

Client Infrastructure – The front-end components are referred to as client infrastructure. It includes all of the apps and user interfaces needed to use the cloud platform.

Although no two clouds are the same, there are a few common cloud architectural models. Public, private, hybrid, and multi-cloud architectures are among them. Here’s how they stack up:

  • Public cloud architecture is one in which computing resources are owned and maintained by a cloud services provider. The Internet is used to exchange and redistribute these resources among multiple tenants. Reduced operational expenses, easy scalability, and little to no maintenance are among the advantages of the public cloud.
  • Private cloud architecture describes a privately owned and controlled cloud, typically in a company’s on-premises data center. Private clouds Although private cloud architectures are often more expensive than public cloud systems, they are more customized and provide more strict data security and compliance alternatives. On the other hand, private clouds can span many server locations or leased space at widely dispersed colocation facilities.
  • Hybrid cloud architecture: A hybrid cloud system combines the public cloud’s operational efficiencies with the private cloud’s data security features. Hybrid clouds consolidate IT resources by combining public and private cloud architectures, allowing enterprises to shift workloads between environments based on their IT and data security needs.
  • A multi-cloud architecture makes several different public cloud services. A multi-cloud architecture provides more flexibility in selecting and deploying cloud services that are most likely to meet varying organizational requirements.

Cloud Computing Architecture Benefits:

By using cloud computing architecture, organizations can minimize or remove their dependency on an on-premises server, storage, and networking infrastructure.

Organizations that implement cloud architecture frequently move IT resources to the public cloud, obviating the need for on-premises servers and storage, as well as IT data center real estate, cooling, and power, and replace them with a monthly IT expense.

One of the main reasons for cloud computing’s current popularity is the transition from capital investment to operating expense. others are given below : 

  • It simplifies the overall cloud computing infrastructure.
  • Reduces the amount of data processing required.
  • Assists in the provision of strong security.
  • It becomes more modularised.
  • As a result, catastrophe recovery is improved.
  • Provides easy access to users.
  • Reduces the cost of IT operations.

Components of the Cloud Computing Architecture

In the following section the key details of cloud computing architecture has been discussed:

Hypervisor: It refers to a virtual machine monitor that delivers Virtual Operating Platforms to all users. It also handles guest operating systems in the cloud. On the back end, it operates a distinct virtual machine with software and hardware. Its major goal is to divide and distribute resources.

Software for Management: Its job is to oversee and monitor cloud operations while implementing various techniques to improve cloud performance. it also looks after the management of disaster contingency plans, compliance auditing auditing auditing auditing auditing auditing auditing auditing auditing auditing auditing audit

Software for Deployment: It includes all of the essential installs and configurations to start a cloud service. A deployment software is used for every cloud service deployment.

Network: It is the link between the front-end and the back-end. Additionally, every user has access to cloud resources. It assists users in connecting to the network and customizing the route and protocol. It is a cloud-based virtual server that is highly adaptable, secure, and cost-effective.

Cloud Server: Cloud storage is a cloud computing approach to store data over the internet by a cloud computing technician who manages and administers the data storage as a service.

Cloud Storage: Every piece of information is saved and accessible by a user from anywhere on the internet. It can be scaled at runtime and is accessed automatically. Cloud storage data can be changed and retrieved via the internet.


Organizations may securely construct applications and employ cloud services depending on customer requirements thanks to cloud computing architecture. In this article, we briefly glossed over cloud computing and the benefits of cloud computing architecture, cloud computing architecture, and cloud computing architecture components in this article. As a result, we now have a thorough understanding of Cloud Computing Architecture.

Several Cloud Certification Courses are open to any Cloud Architect who wants to learn more about Amazon Web Services.
