What is Cloud Infrastructure? All You Need To Know

Cloud computing is a way of accessing computing resources like storage, servers, databases, networking, software, and even artificial intelligence tools over the internet, “the cloud.” Instead of physically owning and maintaining these resources yourself, you can access them on-demand from a cloud service provider like Amazon Web Services (AWS) or Microsoft Azure. This eliminates the need for upfront investment and allows you to pay only for what you use, similar to a utility bill.

One of the key benefits of cloud computing is its scalability. You can easily increase or decrease your resource usage as your needs change, without having to buy or sell physical equipment. This makes it ideal for businesses of all sizes, from startups to large enterprises. Additionally, cloud computing offers improved reliability and disaster recovery, as your data is stored in secure data centers that are geographically distributed.

Cloud computing has become an essential part of modern life. Many of the services we use daily, such as Gmail, Netflix, and social media platforms, are powered by the cloud. It is also being used increasingly in businesses for tasks such as data analytics, customer relationship management, and artificial intelligence development.

How does Cloud Infrastructure work?

Combination of all the cloud infrastructure components such as network, software, computing power, and hardware resources to support cloud computing. In this process, physical components like networking equipment, hardware, storage arrays, and servers attach through virtualization technology that is used to abstract resources from physical components. Virtual networks are designed over physical components allowing users to access cloud services from any part of the world. Cloud infrastructure offers advantages like scalability, cost-effectiveness, and flexibility by providing access to cloud storage from any part of the world. In the blog, we will get to know more about the components of cloud infrastructure and different types of cloud infrastructure.

What are the components of cloud infrastructure?

There are many different types of components of cloud infrastructure that are important for creating a cloud computing environment and allowing users to access virtualized resources. The main components of cloud infrastructure are:


Physical hardware is necessary for every cloud infrastructure, which can be placed at different geographical locations. The hardware involves servers, backup devices, firewalls, load balancers, storage arrays, and networking equipment such as routers, and switches. Cloud also requires hardware as a part of its infrastructure.


Virtualization is the development of a virtual environment that allows hardware-free IT services. In the case of cloud infrastructure, virtualization software extracts computing power and data storage from the hardware and allows the user to interact with the cloud infrastructure by using the graphical user interface (GUI) from their device.


Cloud infrastructure is basically based on cloud storage which allows users or organization to store their information in cloud-based files rather than a local hard drive. Users or organizations can access their data through the internet from cloud-based applications. Microsoft Azure, Amazon Simple Storage Service, and Google Cloud Service are examples of third-party cloud service providers that are responsible for maintaining and managing data and providing backups when needed.


The cloud network is made up of physical wires, switches,  and load balancers which allows organizations to connect different data storage, applications, and microservices across different servers and data centers. Virtual networks are designed on top of these physical components that ensure cloud services are easily available and accessible to users.

These are the main components of cloud infrastructure that help in creating a cloud environment and these clouds have different infrastructures. These cloud infrastructures are chosen by organizations based on their requirement. Let us discuss the different cloud infrastructures.

What are the different types of Cloud Infrastructure?

Below the list of various types of cloud infrastructure for businesses.


In the public cloud, an organization uses the services of a third party by paying them a fee for using the cloud. The stored in the cloud is maintained by the third party or cloud service provider and accessed by the organization by using their service through the internet. Scalability and flexibility are the biggest advantages of using the public cloud and the availability of the public cloud by the service providers at a minimal fee.


Private Cloud Infrastructure is owned, managed, and accessed by a single organization. Organizations that handle very important data use private cloud infrastructure. Unlike the public cloud, these organizations do not share their resources with other organizations. The organization’s IT team alone is responsible for maintaining and managing all software and hardware of cloud infrastructure.


Hybrid Cloud is the combination of both the public cloud and private cloud infrastructure. Some organizations use both the public cloud for some of their workload and the private cloud for others. The hybrid model allows organizations to take the benefit of the public cloud that offers lower cost and scalability for less sensitive data and can be used to share resources while maintaining the most sensitive data in the private cloud.

These are three different types of cloud infrastructure used by organizations based on their requirement. These cloud infrastructures have different delivery models, organizations choose these models based on their needs. Let us have a clearer view of different cloud infrastructure delivery models.

What are the different Cloud Infrastructure delivery models?

Cloud infrastructure is provided by a third party and made available to the user through the Internet. There are three different types of cloud infrastructure available as per the user’s requirement.


Software as a Service (SaaS) is one of the most popular cloud infrastructures that allows users to access software from their browser. SaaS is fully managed by a third party and is responsible for managing software applications, coding, hosting, and monitoring, and allows users to access applications virtually with the help of the internet.


Platform as a Service (PaaS) is a cloud infrastructure in which a third party provides the entire infrastructure to the client. Infrastructure includes data, networks, servers, virtualization, and hardware and software required by the organization to build, develop, run, and manage their application without the cost and complexity that typically come with building an on-premises IT infrastructure. The PaaS allows organizations to deploy, develop, operate, and test their application in a cloud environment. The Paas is managed by a third party but the user handles the application running on top of it.


Infrastructure as a Service (IaaS) is a cloud infrastructure service in which a third party provides infrastructure as a cloud service it means access to cloud servers, data storage, networking tools, and operating systems while service providers take care of hardware, hard drives, storage, and servers and has the responsibility of taking care of issues and repair it. IaaS is a pay-to-use cloud service.


Cloud Infrastructure is the foundation of cloud computing providing important computing power, storage capacity, and networking capabilities to support cloud-based applications and services. Cloud infrastructure consists of different components such as network, hardware, storage, and virtualization which are placed in data centers. These components are designed in such a way that these components are flexible, scalable, and resilient. We have also discussed the different types of cloud infrastructure models Such as Software as a Service(SaaS), Infrastructure as a Service(IaaS), and Platform as a Service(PaaS) these cloud delivery models have different qualities and organizations can choose any cloud infrastructure delivery model based on their requirement.
