Cloud computing is one of the most significant advances in technology, offering access to computing resources beyond the limitations of traditional on-premise computing. Such a paradigm shift moves away from conventional on-premise infrastructure towards scalable and flexible services that provide for ubiquitous data storage, processing and applications deployment of cloud services. Cloud computing constitutes an evolving network of virtualized assets, including servers, garages and networks, for inexpensive scalability and accessibility using business entities.

Read ahead to understand the essential elements of the structures that enable cloud computing, aka the cloud computing architecture. 

What is Cloud Computing Architecture?

The term “cloud computing architecture” refers to the structural organization of elements within a cloud computing setting. This covers all the aspects of hardware, software, networking, and the services involved.

Take for example a public cloud such as Amazon Web Services (AWS). In AWS,  the front end deals with the user interface and clients, and the back end consists of servers, storage, and networks. The cohesive shape permits customers to access computing sources like digital machines, databases, and applications on call without hardware infrastructures.

Components of Cloud Computing Architecture

The core components of Cloud Architecture are: 

• Front-End: The user interface and the cloud service are part of the front end of cloud computing architecture. Users access applications and data via web browsers or other user interfaces, like mobile phones, laptops, and desktops. For instance, Google Docs (a cloud-based collaborative document editing platform) is among the few front-end applications that allow for creating and/or editing documents on the go in a web browser.
• Back-end: The backend comprises the entire Cloud Infrastructure service, which encompasses servers, storage, virtualization software, network devices, and other components. It holds data in custody and provides the demanded service. A strong backend infrastructure, such as Google Cloud, as a cloud service provider, hosts and manages the resources and services available to users.
• Cloud Computing Service Model: There are different types of cloud computing service models. As the name suggests, the type determines the functions that a particular cloud computing model will perform. The three types of services are: 

1. 1. Infrastructure-as-a-Service (IaaS): Virtually creates remote computer resources based on the web. They comprise virtual machine rent, storage, and networks, such as Amazon Web Services EC2 and Microsoft Azure Virtual Machines. Google Compute Engine, etc. 
   2. Platform-as-a-Service (PaaS): Provides a place where customers can write, execute, and administer their applications without worrying about designing and supporting infrastructural aspects. There are examples like Google App Engine and Microsoft Azure App Service. 
   3. Software-as-a-Service (SaaS): Provides the delivery of the software application through online platforms, thus making it unnecessary for the users to download and operate or update them on their devices. The software is accessible without the installation of physical servers and upgrades. Some of them are Salesforce, Microsoft 365, and Google Workspace.

Together, the front-end, back-end, and service model constitute a full architectural design for cloud computing, enabling the provisioning of distributed, flexible, and pay-as-you-go services.

How does it work?

Cloud architecture is all about the arrangement of the materials that form the environment for cloud computing platforms. It combines SOA (Service Oriented Architecture) and EDA (Event Driven Architecture). In the back end, cloud service providers provide resources, services, data storage, and applications. Using a network, data can be transported between front-end and back-end cloud architecture components. The service model determines how the communication will take place. 

This means that cloud computing enables users to utilize remote computing resources on demand, including servers, storage, databases, networking, software, analytics, and intelligence through the internet rather than possessing such amenities at their locality.

Thus, whenever a user interacts with the front end (or client-side interface) of the cloud computing architecture, it sends queries to the back end, where the service model executes the specific request.

Cloud computing is a dynamic approach for offering computation resources utilizing the web. On-demand users access and use resources which reduce costs and enhance efficiency. This specific implementation might differ for each service model or a chosen cloud provider.
