Cloud Computing Architecture

  • It is a combination of service-oriented architecture (SOA) and event-driven architecture.
  • Cloud computing architecture is divided into the following two parts.
    • Front End
    • Back End


Front End

  • The front end is used by the client. The front end includes web servers (including Chrome, Firefox, internet explorer, etc.) and also include thin & fat clients, tablets, and mobile devices.

Back End

  • The back end is used by the service provider.
  • It includes a huge amount of data storage and security mechanism.

Components of Cloud Computing Architecture


Cloud Components

1. Client Infrastructure

  • It is a Front end component. It provides GUI (Graphical User Interface).

2. Application

  • The application may be any software .

3. Service

  • It manages that which type of service you access. Cloud computing offers the following three type of services:
 Cloud services

Cloud services

Software as a Service (SaaS)

Platform as a Service (PaaS)

  • It is also known as cloud platform services. It is similar to SaaS, but the difference is that PaaS provides a platform for software creation, but using SaaS, we can access software over the internet without the need of any platform.
  • Example: Windows Azure,, Magento Commerce Cloud, OpenShift.

Infrastructure as a Service (IaaS)

  • It is also known as cloud infrastructure services. It is responsible for managing runtime environments, middleware, and applications data.
  • Example: Amazon Web Services (AWS) EC2, Google Compute Engine (GCE), Cisco Metapod.

4. Runtime Cloud

  • It provides the execution and runtime environment.

5. Storage

  • It provides a huge amount of storage capacity in the cloud to store.

6. Infrastructure

  • It provides services on the host level, network level, and application level. Cloud infrastructure includes hardware and software components such as servers, storage.

7. Management

  • Management is used to manage components such as application, service, runtime cloud, storage, infrastructure.

8. Security

  • Security is a back end component of cloud computing. It implements a security mechanism in the back end.

9. Internet

  • The Internet is medium through which front end and back end can interact and communicate with each other.
