Cloud hosting has emerged as an efficient web hosting in India for websites needing scalable and reliable infrastructure. By leveraging virtualisation and distributed servers, cloud host provides flexible on-demand resources ideal for fluctuating traffic. This article explains cloud hosting, how does it works and other related aspects.

What is Cloud Hosting

Cloud hosting refers to hosting websites or applications on virtualised, distributed computing resources over the internet. Instead of being hosted on a single physical server, cloud hosting allows resources to be provisioned across a network of servers in different data centre locations. 

Resources like computer power, storage space, bandwidth, and more can be quickly allocated to customer websites on demand.

How Does Cloud Hosting Work?

Cloud hosting uses virtualisation technology to divide physical computing resources into isolated virtual resources that can be assigned independently to different websites. So, instead of storing just one website on a single physical server, cloud hosting enables that server to be portioned out among multiple virtual web servers, each running a different website. 

The cloud hosting price varies based on the resources consumed, allowing customers to control costs. The cloud infrastructure presents an abstraction layer over the actual physical infrastructure, so all virtual servers appear as independent units to end users.

But behind the scenes, load balancing algorithms shift website workloads dynamically between distributed data centres to ensure smooth performance. Automated failover mechanisms take over instantly if any data centre goes offline unexpectedly. 

Types of Cloud Hosting Models

  1. Public Cloud

In public cloud hosting, computing resources are hosted by a third-party cloud provider like AWS, Google Cloud or Microsoft Azure. The public cloud infrastructure is shared between many different customers or tenants. The public cloud is best suited for workloads that need to scale rapidly or have unpredictable resource requirements.

  1. Private Cloud

An organisation can only have one client in a private cloud. Here, you get complete control over resources, security, and who has access to data and applications. 

The client builds their private cloud computing environment on-premises or becomes a tenant in a provider’s private cloud data centre. Best cloud hosting offers the highest levels of security and customisation but at a higher cost.

  1. Hybrid Cloud

In hybrid cloud hosting, on-premises private clouds combine with third-party public clouds. Critical and sensitive data continues to be hosted privately while public cloud resources handle workload fluctuations. Hybrid cloud hosting offers the ideal balance of cost-efficiency, scalability, security and control.

Benefits of Cloud Hosting

  • High Availability

Cloud hosting deploys a distributed network of servers instead of just one server, so website downtime risks are minimised greatly. Instant failover ensures continued uptime.

  • Scalability

Cloud hosting allows seamless and on-demand scalability. The network auto-provisions more bandwidth, disk space and other resources needed to manage sudden spikes in traffic.

  • Flexibility

You can choose from a menu of cloud infrastructure services, including storage, servers, databases, networking and software. Scale these cloud resources up or down based on changing business requirements.

  • Managed Services

With managed cloud hosting, the service provider configures, monitors, updates and secures the cloud network on your behalf. You can focus on more strategic and business-oriented tasks.


Cloud hosting leverages virtualisation and distributed computing to provide flexible, on-demand resources for modern websites and applications. By eliminating dependence on single physical servers, cloud hosting in India enables high scalability, resilience, and availability, which is ideal for businesses with fluctuating or unpredictable traffic.
