What is Cloud Computing Architecture?

Cloud Computing is a rapidly growing technology widely adopted by both startups and large enterprises due to its scalability and flexibility. Organizations use cloud platforms to store and access data securely from anywhere, at any time.

The architecture of Cloud Computing is primarily divided into two main sections:

Front End

Back End

These two sections interact with each other through the internet.

i. Front End

This is the user-facing part of cloud computing. It includes applications and user interfaces that allow clients to access the cloud. Common examples include web browsers or custom-built applications by companies.

ii. Back End

The back end is managed by cloud providers and includes data storage, servers, virtual machines, and security systems. It is responsible for handling traffic, security, data processing, and more.

Key Components of Cloud Computing Architecture

Let’s explore the main components of cloud architecture:

1. Hypervisor

Also called the Virtual Machine Monitor, the hypervisor consists of hardware, software, or firmware that allows multiple virtual machines (VMs) to run on a single physical machine. It acts as a platform that lets guest operating systems interact with the cloud environment.

2. Management Software

This software handles resource allocation, monitoring, scheduling, and maintenance. It ensures on-time delivery of services, enhances performance, provides disaster recovery, and handles compliance auditing.

3. Deployment Software

Deployment software is responsible for initiating services like SaaS, PaaS, and IaaS. It includes necessary installations and configurations required to launch these services from the back end.

4. Connectivity Routes

Cloud infrastructure is connected via high-speed internet routes. These routes manage data transmission between servers and users. The system also allows customization of network routes and communication protocols.

5. Cloud Server

A cloud server is a virtual server hosted within a cloud infrastructure. These servers are secure, scalable, fast, and more reliable than traditional physical servers. They are easy to upgrade and cost-effective.

6. Cloud Storage

Cloud storage allows users and applications to store, retrieve, and manage data remotely. It offers flexibility to scale storage as needed and is accessed via APIs or online interfaces. This storage is essential for applications that need reliable and fast access to large volumes of data.

Cloud-Based Service Models

Cloud services are categorized into three primary delivery models:

i. SaaS (Software as a Service)

In SaaS, cloud providers host software applications that users can access via the internet without installing them locally. This model is scalable and reduces the burden of software management on users.

ii. IaaS (Infrastructure as a Service)

IaaS offers virtualized computing resources over the internet. Businesses rent servers, storage, and networking components from the cloud provider. It eliminates the need to purchase and maintain physical hardware.

iii. PaaS (Platform as a Service)

PaaS delivers hardware and software tools over the cloud for application development. It supports developers by providing a ready-to-use platform, eliminating the need for installing tools or managing infrastructure.

Conclusion

Cloud Computing Architecture is simple yet powerful. Its components and service models offer flexibility, security, and cost-efficiency. With cloud services, businesses can scale resources as needed and focus on innovation without worrying about infrastructure.
