Cloud computing architecture refers to the design and structure of cloud-based systems, including the components, services, and interrelationships that comprise the cloud environment. A well-designed cloud architecture ensures optimal performance, security, scalability, and manageability of cloud resources. The architecture typically consists of two main components: the front end and the back end, connected through a network, usually the internet.
Front-end: The front-end is the user interface and comprises the client devices (such as laptops, smartphones, and tablets) and applications that users interact with to access cloud services. These applications can be web-based or native apps, and they communicate with the back end through APIs (Application Programming Interfaces).
Back-end: The back-end is the cloud infrastructure, which consists of the resources and services provided by the cloud provider. This includes:
Compute resources: Virtual machines or containers that host and run applications, perform processing tasks, and execute code.
Storage resources: Databases and file systems that store data and make it available for processing and retrieval.
Networking resources: Network infrastructure that enables the communication between different components, such as virtual networks, load balancers, and firewalls.
Management and orchestration: Services and tools that help manage, monitor, and automate the provisioning and operation of cloud resources.
Middleware services: Platform-level services that support application development, integration, and operation, such as authentication, caching, and messaging.
In addition to these components, cloud computing architecture can be organized based on different service models and deployment models:
Service Models:
Infrastructure as a Service (IaaS): The cloud provider offers virtualized computing resources such as virtual machines, storage, and networking infrastructure over the internet.
Platform as a Service (PaaS): The provider offers a platform that allows developers to build, deploy, and manage applications without worrying about the underlying infrastructure.
Software as a Service (SaaS): The provider delivers software applications over the internet, accessible through a web browser without the need for installation or maintenance.
Deployment Models:
Public Cloud: Computing resources are provided by a third-party cloud service provider and shared among multiple users or organizations.
Private Cloud: A cloud environment dedicated to a single organization, offering greater control, security, and customization. It can be hosted on-premises or by a third-party provider.
Hybrid Cloud: A combination of public and private clouds, allowing organizations to leverage the benefits of both while optimizing workload placement and data security.
When designing a cloud computing architecture, it’s essential to consider factors such as performance, scalability, security, and cost optimization to ensure the cloud environment meets the organization’s needs and objectives.

The authors discuss the use of enterprise architecture patterns to implement cloud computing effectively and efficiently to deliver business results.
This guide provides insights into the convergence of cloud computing and enterprise architecture, offering strategies for technological and business advancement. (300 pages)
This presentation provides a quick overview of the link between enterprise architecture and cloud computing. If you are moving from the one-off, siloed approach to cloud computing to integrating it with the enterprise, this is a good place to start.
This presentation provides a quick overview of the link between Service Oriented Architecture (SOA) and cloud computing. This complimentary relationship creates more business value if we understand how to use it and provide appropriate governance to ensure results.
Is the world's move to the cloud mean a move away from Enterprise Architecture? Is EA toast? This debate takes sides and helps you see the big picture of enterprise architecture in the age of cloud computing.
The authors argue for an architected approach to cloud computing instead of the oft followed individual application or "siloed" approach.
This paper presents a graphical approach to integrate cloud computing with the enterprise architecture of an organization – the purpose is to visualize the areas with the best benefits for cloud computing adoption and the impact of such a cloud computing implementation.
