Architecture of Cloud Computing

  • Difficulty Level : Easy
  • Last Updated : 25 Mar, 2021

Cloud Computing , which is one of the demanding technology of the current time and which is giving a new shape to every organization by providing on demand virtualized services/resources. Starting from small to medium and medium to large, every organization use cloud computing services in storing information and accessing that from anywhere and any time only with the help of internet. In this article we will know more about the internal architecture of cloud computing.

Transparency, scalability, security and intelligent monitoring are some of the most important constraints which every cloud infrastructure should experience. Current research on other important constraints is helping cloud computing system to come up with new features and strategies with a great capability of providing more advanced cloud solutions.

Cloud Computing Architecture :
The cloud architecture is divided into 2 parts i.e.

  1. Frontend
  2. Backend

The below figure represents an internal architectural view of cloud computing.


Architecture of Cloud Computing

Architecture of cloud computing is the combination of both SOA (Service Oriented Architecture) and EDA (Event Driven Architecture). Client infrastructure, application, service, runtime, storage, infrastructure, management and security all these are the components of cloud computing architecture.

1. Frontend :
Frontend of the cloud architecture refers to the client side of cloud computing system. Means it contains all the user interfaces and applications which are used by the client to access the cloud computing services/resources. For example use of a web browser to access the cloud plat form.

  • Client Infrastructure – Client Infrastructure refers to the frontend components. It contains the applications and user interfaces which are required to access the cloud platform.

2. Backend : 
Backend refers to the cloud itself which is used by the service provider. It contains the resources as well as manages the resources and provides security mechanisms. Along with this it includes huge storage, virtual applications, virtual machines, traffic control mechanisms, deployment models etc.

  1. Application –
    Application in backend refers to a software or platform to which client accesses. Means it provides the service in backend as per the client requirement.
  2. Service –
    Service in backend refers to the major three types of cloud based services like SaaS, PaaS and IaaS. Also manages which type of service the user accesses.
  3. Cloud Runtime –
    Runtime cloud in backend refers to provide of execution and runtime platform/environment to the virtual machine.
  4. Storage –
    Storage in backend refers to provide flexible and scalable storage service and management of stored data.
  5. Infrastructure –
    Cloud Infrastructure in backend refers to hardware and software components of cloud like it includes servers, storage, network devices, virtualization software etc.
  6. Management –
    Management in backend refers to management of backend components like application, service, runtime cloud, storage, infrastructure, and other security mechanisms etc.
  7. Security –
    Security in backend refers to implementation of different security mechanisms in the backend for secure cloud resources, systems, files, and infrastructure to end-users.
  8. Internet –
    Internet connection acts as the medium or a bridge between frontend and backend and establishes the interaction and communication between frontend and backend.

Benefits of Cloud Computing Architecture :

  • Makes overall cloud computing system simpler.
  • Improves data processing requirements.
  • Helps in providing high security.
  • Makes it more modularized.
  • Results better disaster recovery.
  • Gives good user accessibility.
  • Reduces IT operating costs.
