Cloud Computing Architecture

Cloud computing architecture combines the strengths of Service-Oriented Architecture (SOA) and Event-Driven Architecture (EDA). This hybrid design provides higher bandwidth, allowing you to access your data stored in the cloud from anywhere.

Here is the graphical representation of a cloud computing architecture:

As illustrated, cloud computing architecture is partitioned into two parts:

Front-End Cloud Architecture

Front-end architecture is one of the major components of the cloud computing system that allows you to access cloud computing services. It is a client infrastructure comprising various web applications, user interfaces, local networks, and mobile devices. You can send requests through the front-end system over the Internet, which lets you connect with the back-end architecture for data storage and processing. 

Back-end Cloud Architecture 

The cloud service provider handles the back-end architecture to manage and administer all the resources required for cloud services. It includes middleware, which connects the front-end interfaces to the back-end infrastructure. The provider also uses middleware to improve the front end’s functionality and safeguard the data. Back-end architecture includes different subcomponents to deliver cloud services to users easily. Let’s discuss about each of them: 

• Application: An application can be a software or platform that you need to access the cloud services. 
• Runtime Cloud: Runtime cloud is a virtual environment that serves as an operating system, enabling the back-end system to run programs simultaneously. 
• Service: A service component that helps the back-end interface manage each operation that executes on the cloud. 
• Storage: A component that provides a scalable way to store and handle data in the cloud. 
• Infrastructure: Cloud infrastructure includes hardware and software resources, such as servers, networking, or databases, needed to provide on-demand computing services via the Internet.   
• Management: A component that helps manage all the back-end components and establish the connection between front-end and back-end systems. 
• Security: Security is integrated at the front-end and back-end architecture to prevent data loss and secure the entire cloud computing system. 

Top Three Cloud Computing Service Providers

Amazon Web Services (AWS)

AWS, a subsidiary of Amazon, is one of the most popular cloud computing platforms. Statista, a statistical portal for market data, reported that around 48% of professional software was developed using AWS as of 2024. 

AWS provides over 200 fully featured services, including storage, networking, compute, development tools, databases, IoT, security, analytics, and enterprise applications. This makes AWS an all-in-one solution for businesses of any size on a pay-as-you-go basis.

Once you build your applications, you can automatically deploy and scale them efficiently using the fully automated Google Kubernetes Engine. GCP’s Google Security Operations (SecOps) also helps you secure your applications from threats faster.  

Types of Cloud Deployment Models

Cloud deployment models help you understand how cloud services are available to users and organizations. Here are four types of cloud models:

Public Cloud

Third-party cloud service providers such as AWS, Azure, and GCP own and operate public clouds. These providers offer scalable resources and services over the Internet to multiple clients without significant upfront investment. However, public clouds can sometimes present few security risks as they are open to everyone. By properly configuring the cloud settings and implementing strong security measures, you can still protect your data and maintain a secure environment. 

Private Cloud

In a private cloud, only a single user or organization can use the entire environment. It can be hosted on-premises or through a third-party provider but does not share resources with anyone else. A private cloud is set up in a secure environment with strong firewalls and authentication. Unlike public clouds, private clouds can help users customize resources to meet their specific demands. 

Hybrid Cloud

Hybrid clouds allow you to combine the benefits of public and private cloud environments. This enables you to deploy your app on a secure platform and use the public cloud to save costs. With a hybrid solution, your organization can easily move data and applications across different combinations of cloud models. It helps your business to choose the best option you need at the moment. However, it is difficult to maintain as it involves both public and private clouds.

Community Cloud

The community cloud is similar to the public cloud. However, it is only available to a limited number of users or organizations with the same goals and needs. This cloud model can be managed and hosted either by a community or by a third-party provider. Since data and resources are shared among different organizations, changes made by one organization can affect others. As a result, the community cloud is limited in customization. 

Types of Cloud Computing Services

Cloud computing provides three cloud services, each with different levels of control and flexibility. Choose one that best suits your business requirements.

Infrastructure as a Service (IaaS)

IaaS offers resources and services such as virtual machines, storage, networks, and more required for a cloud IT infrastructure over the Internet. It provides full management control over the operating systems, applications, and storage configurations, just like your own on-premise data center. 

An example of IaaS is AWS EC2 (Elastic Cloud Compute). It allows you to rent virtual servers to run your large-scale applications instead of purchasing expensive physical hardware. You can even scale the server during peak traffic times. 

Platform as a Service (PaaS)

PaaS provides a platform with built-in development platforms and tools to help you build, test, and deploy your applications. It streamlines the development process without worrying about patching, resource allocation, software maintenance, or other server administration routines. 

Microsoft Azure App Service is a PaaS solution that lets you quickly develop websites, mobile apps, and APIs using different programming languages. Using such solutions, your development teams can collaborate on building without managing the underlying infrastructure. 

Software as a Service (SaaS)

SaaS vendors deliver you software applications over the Internet on a subscription basis. You can access these applications via a web browser, eliminating the need to install the service and understand how it is maintained. As a result, you can reduce IT overhead and ensure you have access to the latest software versions without manual updates with SaaS solutions.

Google Workspace is a popular SaaS offering that provides tools like Gmail, Docs, Drive, and more. With it, you can collaborate in real-time without maintaining the operating systems on which the SaaS application is running.
