What is Cloud Architecture?

Cloud architecture is a framework that defines the structure and components of cloud computing. It revolutionizes the way businesses handle their IT infrastructure, providing flexibility, scalability, and cost-effectiveness.

Cloud Architecture Components

Front-end Platform

The front-end component of cloud architecture represents the user interface and client-side applications. For instance, web browsers and mobile apps that interact with cloud services, like Google Drive or Dropbox, exemplify front-end components.

Back-end Platform

The back-end component includes servers, databases, and application logic responsible for data storage, processing, and management. A prime example is Amazon Web Services (AWS), where server clusters handle various tasks.

Main Backend Components


The software that powers the back-end, facilitating data processing and business logic.


Cloud services that provide specific functionalities, such as AWS Lambda for serverless computing.

Runtime Cloud:

The runtime environment where applications and services operate.


Space where data is stored, like AWS S3 for scalable object storage.


The underlying cloud infrastructure, including servers, networks, and data centers.


Tools and services for monitoring and managing cloud resources.


Ensuring data protection and cloud system security through encryption and access controls.

How Does Cloud Architecture Work?

Cloud architecture seamlessly integrates front-end and back-end components. User requests are received by the front-end, which communicates with the back-end for data processing. This orchestration ensures users access applications and data efficiently.

Types of Services

Cloud services come in three flavors:

IaaS (Infrastructure as a Service): Offers virtualized computing resources, such as AWS EC2.

PaaS (Platform as a Service): Provides a platform for developing, testing, and deploying applications, like Google App Engine.

SaaS (Software as a Service): Delivers software applications over the internet, including Microsoft Office 365.

Cloud Architecture Layers

Cloud architecture comprises three layers:

  • Hardware: Physical components like servers and storage devices.
  • Virtualization: Abstraction layer that creates virtual resources from physical hardware.
  • Application & Service: Software and services hosted on virtualized resources, accessed by users.

Types of Cloud Architecture

  • Public Cloud: Services offered to the public, e.g., AWS, Azure.
  • Private Cloud: Dedicated infrastructure for a single organization, enhancing security.
  • Hybrid Cloud: A combination of public and private clouds, allowing data and workloads to move seamlessly.

Benefits of Cloud Architecture

  • Cost-effective: Pay only for what you use.
  • Faster time to implement: Rapidly deploy resources and applications.
  • Scalability: Easily adjust resources as your business grows.
  • Accelerated transformation: Enable digital innovation and agility.
  • Innovation: Access cutting-edge technologies without heavy investments.
  • High availability: Ensure uninterrupted service through redundancy.
  • Strong security: Implement robust security measures to protect data.

Embrace cloud architecture, and unlock its potential to reshape your business and IT landscape.

Why Choose Allied Digital for Cloud Management Services?

Hybrid cloud models are mainstream, as business continuity mandates public cloud adoption and CIOs demand a single pane of glass to manage the IT infrastructure.

Disparate deployments like IaaS, PaaS, and SaaS in the cloud, including application support, backup administration, DevOps, make diverse resource skillsets, a criticality.

Besides the benefits of cloud migration, key cloud management services we offer are cloud enablement, support, proactive management, security, DevOps, capacity planning and cost control.
