What is Cloud Computing Architecture?

Cloud computing architecture refers to the structure and design of the systems and components that comprise a cloud environment. It includes various elements such as virtual machines, storage systems, networking infrastructure, and software layers.

The architecture is designed to ensure scalability, reliability, and flexibility in delivering cloud services. It is more like a blueprint that guides how the cloud operates and how different components interact.

Examples of cloud computing architecture are Google Apps, Salesforce Dropbox, Slack, Hubspot, and Cisco WebEx.

What Are the Components of Cloud Computing Architecture?

Let’s get started with the components that make it all possible. Cloud-based architecture consists of three components: front-end platform, back-end platform, and cloud-based delivery. The front-end and back-end are referred to as the face and brain simultaneously. Furthermore, cloud-based delivery allows businesses to transmit information via application platforms.

1. Front-end Cloud Architecture

Frontend architecture refers to the design and structure of the client-facing components in the cloud computing environment. It focuses on the user interface, user experience, and how users interact with cloud-based applications and services.

The major front-end components include:

• User interface
• Software
• Client device or network

2. Back-end Cloud Architecture

Backend architecture is the backbone of a cloud computing environment. It focuses on the server-side components that handle data and services processing, storage, and management. This includes databases, application servers, virtual machines, load balancers, and other infrastructural elements.

The significant components of backend architecture are:

• Application
• Service
• Cloud runtime
• Storage
• Infrastructure and architecture
• Management
• Security

3. Cloud Delivery

Cloud delivery, or cloud service delivery, refers to providing services and resources to users over the Internet. It involves the efficient and secure distribution of applications, data, and computing power from the cloud provider to the end-users.

It encompasses various aspects such as network connectivity, data transmission, service availability, and scalability. It enables users to access and utilize cloud services anytime, anywhere, without needing on-premises infrastructure. There are a few prominent methods in which it delivers its service. Those are:

• Software as a Service (SaaS) Model

In the SaaS model, cloud providers offer software applications to users over the Internet and handle their maintenance, eliminating the need for users to install and maintain the software on their own devices. Instead, users can access the software through a web browser or a dedicated application.

• Platform as a Service (PaaS) Model

With PaaS, cloud providers offer a platform with the necessary infrastructure and tools for developing, testing, and deploying applications. It provides a complete development environment, including operating systems, databases, and programming languages, so developers can focus on building their applications without worrying about managing the underlying infrastructure.

• Infrastructure as a Service (IaaS) Model

In the IaaS model, cloud providers offer virtualized computing resources over the Internet. This includes virtual machines, storage, and networking capabilities. IaaS, use gives users control over the underlying infrastructure than other cloud models. They can provide and manage virtual machines, storage, and networks to meet their needs.

As we’ve learned about the essential elements of cloud architecture, it's now the time to explore its types and help you choose the one that will be the ideal fit for your business objectives.

Types of Cloud Computing Architecture Models

You can choose from three main types of cloud computing architecture models: public, private, and hybrid. Selecting the right model depends on your business objectives, security priorities and scalability demands. Let's look at each in brief.

1. Public Cloud: It is the cloud computing model where a third-party service provider owns and operates the cloud infrastructure. It is called public because the infrastructure is shared among multiple users or organizations. With it, users can access computing resources, such as virtual machines, storage, and applications, over the Internet.

2. Private Cloud: A private cloud is a computing model where the cloud infrastructure is dedicated to a single organization. The private cloud is not shared with other users. It can be hosted on-premises or by a third-party service provider. It offers more control, security, and customization options than the public cloud. Also, approximately 84% of organizations have used a private cloud at least once for corporate functions.

3. Hybrid Cloud: A hybrid cloud combines both public and private cloud environments. It allows organizations to leverage the benefits of both models. With it, you can have specific resources and applications hosted in the public cloud while keeping others in the private cloud. This flexibility allows you to optimize your infrastructure based on security, scalability, and cost-efficiency needs.

Having explored the different types, the next section will dive into how cloud computing architecture is beneficial for your business and its key disadvantages.
