Introduction to Cloud Computing Architecture and Management

Cloud computing technology has brought tremendous changes to businesses of all sizes, across different geographies and industry verticals. It offers mind-bogglingly fast processing power, and automation features that facilitate high availability, scalability, and resilience.

Cloud computing is an emerging technology that plays a crucial role in delivering scalable services to resource-hungry Internet users. It has become the backbone of virtually everything we do, with organizations of all sizes adapting it for data storage and flexible operations.

This article provides an overview of cloud computing architecture, its components, delivery models, management, benefits, and drawbacks. It also covers front-end and back-end cloud architecture and the different types of cloud computing services, including public, private, and hybrid clouds.

Cloud Computing in Simple Terms

Cloud Computing is the combination of computer technology and the internet based development of the cloud. It allows users to remotely access a massive network of computers from a single location. Cloud services come in various forms such as storage, server, database, software, networking, intelligence, and analytics. It is a cost-effective alternative to traditional hosting centers for eBusiness applications and services. One of its core advantages is that it is highly automated and scalable, providing optimum performance and data security. Cloud computing is gaining immense popularity in the business world, as it can defer expenses, offer self-service, scalability, and redundancy so that there is no single point of failure. The cloud is made up of resources such as virtual desktops, software platforms, servers, applications, and data storage accessible via network devices such as routers and switches. Cloud computing is designed to deliver all types of services on the internet.


Cloud computing architecture has two main components, the front-end
and the back-end. The front-end, which serves as the client interface, communicates with the back-end through a network or internet connection. The back-end protects vital information from client-facing technology and handles queries through a predetermined protocol.

To create a cloud environment for your business, off-the-shelf components are recommended, along with highly scalable servers, applications tailored to your business needs, and a budget for scalability.

Effective cloud computing planning is essential to save time and money and increase return on investment. Choose the appropriate cloud architecture that best suits your business to ensure your data stays current and well-equipped for the future.

Components of Cloud Computing Architecture

Cloud computing architecture consists of three main components:

1. Front-end: It refers to the client-side interface responsible for providing access to cloud computing platforms. It includes web browsers, mobile applications, and thin clients.

2. Back-end: It is responsible for providing resources for cloud services to operate. This includes servers, storage devices, and databases.

3. Cloud-based delivery: It provides a platform to transmit information via cloud-based application platforms. The three types of infrastructure used in cloud-based delivery services are Infrastructure-as-a-service (IaaS), Platforms-as-a-service (PaaS), and Software-as-a-service (SaaS).

Understanding Front-End Cloud Architecture

Front-end architecture in cloud computing refers to the end-user interface, encompassing various components working together. It includes web browsers, local networks, graphics cards, and operating systems that provide access to customized programming from providers like Google and Microsoft. Let’s explore the primary components of front-end architecture:

* USER INTERFACE: This interface is the everyday interface that connects end-users with cloud computing, allowing them to complete tasks without opening any local software. Popular interaction interfaces are Google Docs, Gmail, and Evernote.

* SOFTWARE: The front-end software comprises client-side applications or browsers that present data to users.

* CLIENT DEVICE OR NETWORK: The client-side device is the hardware on the end-user’s side that could be a mouse, keyboard, or sound card. It doesn’t require exceptional processing power, as the cloud takes care of that job.

Back-End Cloud Architecture

Back-end cloud architecture is the foundation of cloud-based systems. It includes hardware and storage that’s hosted on a remote server and managed by the cloud service provider. A robust back-end cloud architecture should be resilient and long-lasting. Here are the essential components of such an architecture:

* APPLICATION: The user interface for clients is a significant part of the application architecture. It provides back-end services to access client data and handle requests.

* SERVICE: Cloud computing adds utility to every cloud hosting system. Services, such as administration and application programming, storage, and web services facilitate various tasks running on the cloud quickly and efficiently.

* CLOUD RUNTIME: Cloud runtime makes services readily accessible to users, using virtualization technology. It’s like a cloud operating system that allows people to access countless networked servers at any time. Cloud servers act independently from each other and form the main server known as Hypervisors.

* STORAGE: Cloud storage is where data resides within cloud applications. Servers’ capacity is divided into sections that run multiple services using an operating system.

* INFRASTRUCTURE AND ARCHITECTURE: Infrastructure comprises various technologies such as CPU, motherboards, GPU, and accelerator cards, depending on customers’ workload.

* MANAGEMENT: The management software allocates different resources to every task in your business to ensure everyone gets their share of attention.

* SECURITY: Regular system backups and firewall software are necessary to mitigate virtual threats.

An ideal back-end cloud architecture is designed to work seamlessly, ensuring the cloud-based system runs error-free.

Cloud Delivery

Cloud delivery refers to software, infrastructure, and platforms that can be accessed through a web browser from any device with internet capabilities. Technology giants bundle products together and deliver them to clients. There are three types of cloud-based solutions:

– Software as a Service (SaaS): Developers put their applications into a cloud-based delivery system, and customers access them via the Internet. SaaS subscriptions are cost-effective and allow teams to work from anywhere.
– Platform as a Service (PaaS): Users can create and run applications on the cloud and maintain them themselves. Third-party organizations offer technical resources, such as hosting facilities or programming tools.
– Infrastructure as a Service (IaaS): This model provides infrastructure, including virtual and non-virtual servers, and data center space in one place.

The three cloud deployment models are public cloud, private cloud, and hybrid cloud. Public cloud provides economies of scale, while private cloud offers more control and security to larger organizations. Hybrid cloud is a combination of both.

A private cloud is the most suitable option for businesses of every size and type. It offers more control and security, which is vital to organizations with particular security needs. Hybrid cloud provides many advantages for hosting important business applications without compromising performance or data protection.


Cloud management is crucial for any business in today’s fast-paced evolving technological world. To aid in managing the financial, security, and performance monitoring of cloud services, many are turning to cloud management platforms. These services also provide automation capabilities to enhance the efficiency and speed of cloud-based applications while ensuring utmost security.

Cloud management services include built-in automation and orchestration, real-time monitoring tools, analytics and reporting, cost management, flexible workflows, resource optimization, and APIs for interaction and collaboration. These features make it easier for companies to save costs, reduce waste, and improve business management decisions. APIs allow for easy integration of cloud services with advanced tools and analytics, ensuring full control of data at all times.
