What Is Cloud Hosting?

Final: What is cloud hosting

Cloud hosting is a type of web hosting that uses a network of servers to store and deliver website content.

This means your website is not stored on a single server but on a network of servers spread across multiple locations.

What are the Benefits of Cloud Hosting?

Cloud Hosting provides several benefits, including:

  • Flexible pricing structure - You only pay for what you use
  • Easy to scale server resources - You can quickly scale up or down your resources as needed
  • Redundant server environment - If one server fails, another can take its place, ensuring high uptime and availability
  • High uptime and availability - Cloud hosting takes advantage of many servers spread across the cloud network, providing great reliability and uptime
  • Faster website speed and performance - Servers are in different regions, so content is delivered to users faster

How Does Cloud Hosting Work?

Cloud hosting works by combining cloud servers and virtual private servers to offer scalable computing resources and enhanced hosting efficiency. It involves the following key components:


Virtualization is the process of creating multiple virtual machines (VMs) from a single physical server. It enables the creation of multiple virtual servers by abstracting the server’s physical resources, such as CPU, memory, and storage. This allows multiple websites to share the same physical resources, utilizing cloud servers and computing resources efficiently.

Here’s how it works:

  • A hypervisor is installed on the physical server. The hypervisor is a software program that creates and manages the virtual servers.
  • The hypervisor divides the physical resources of the server into virtual resources. Each virtual resource is assigned to a virtual server.
  • The virtual servers are then created. Each virtual server has its operating system and applications.

Resource Pooling

Resource pooling involves consolidating various resources, including processing power, memory, storage, and bandwidth, into a shared pool that can be dynamically allocated and distributed among different applications and users based on their specific needs.

This means you don’t have to purchase or maintain dedicated hardware, as the servers provide scalable computing resources. You only pay for the resources that you use.

Resource pooling is implemented in three ways:

  • Hardware virtualization - The process of dividing a physical server into multiple virtual machines (VMs)
  • Software virtualization - Using a software layer to abstract the physical resources of a server
  • Cloud computing - This involves using a network of remote servers to store and deliver data and applications

Distributed Architecture

Distributed architecture is the distribution of virtual servers across multiple physical machines and data centers.

In a distributed architecture, each virtual server is hosted on a different physical machine. This means that if one physical machine fails, the virtual server running on it will not be affected. The virtual server will be automatically moved to another physical machine.

By distributing virtual servers across multiple data centers, cloud providers can ensure that your website or application is always available, even if one data center fails.

Load Balancing

Load balancing distributes network traffic across multiple servers to optimize resource utilization and improve performance. There are two main types of load balancing:

  • Hardware load balancers - These are physical devices between the internet and your servers. They distribute traffic across your servers based on various factors, such as server capacity, location, and health.
  • Software load balancers - These are software applications that run on your servers. They distribute traffic across your servers similarly to hardware load balancers.

Load balancers work by inspecting incoming network traffic and routing it to the appropriate server. They also perform a variety of other tasks, such as Health checking, SSL offloading, and Web application firewall (WAF).


Scalability is the ability to easily increase or decrease the resources allocated to a website or application. This is done quickly and easily, without any downtime.

Cloud hosting, working through cloud servers, is highly scalable because it uses a pay-as-you-go model, allowing for efficient management of computing resources. This means that you only pay for the resources that you use. As your website or application grows, you can easily add more resources to meet the demand.

Cloud hosting excels in horizontal scalability, which involves scaling resources by adding more instances or replicas rather than increasing the capacity of individual servers.

Pay-As-You-Go Model

The pay-as-you-go model is a pricing model where you only pay for the resources that you use. This means you don’t have to commit to a long-term contract or pay for resources you’re not using.

To optimize your costs using the pay-as-you-go model:

  • Use spot instances - Spot instances are unused cloud resources available at a discounted price. You can use spot instances to save money on your cloud hosting costs.
  • Use reserved instances - Reserved instances are cloud resources you can reserve for a time. By reserving instances, you can get a discount on your cloud hosting costs.
  • Use auto-scaling - Auto scaling is a feature that allows you to automatically scale your cloud resources up or down based on demand. This can help you save money by only using the needed resources.

The pay-as-you-go model is a popular choice for businesses of all sizes.


The Statista Research Department states, “In 2021, 64% of respondents named data loss or leakage as their biggest cloud security concern.”

To mitigate this, cloud providers offer a variety of cloud server security features to help protect your data, including:

  • Physical security - Cloud providers’ data centers are located in secure facilities. Access control, round-the-clock monitoring, and perimeter security are in place to protect these facilities.
  • Network security - The providers use security measures like firewalls, intrusion detection systems, and data encryption to protect your data in transit and at rest
  • Application security - Cloud providers will check and advise on fixing your apps for security flaws. They also offer a variety of security features to help protect your applications, such as authentication, authorization, and access control.
  • Data backup and recovery - Most providers offer a variety of data backup and recovery options

Cloud providers also implement something called data redundancy. This security measure safeguards against data loss in the event of hardware failures or disasters.

Cloud providers use a variety of techniques to achieve data redundancy, including:

  • Replication – Data is replicated across multiple servers. This means your data is stored on multiple servers, so if one server fails, your data is still available on the other servers.
  • Fault tolerance - Fault-tolerant systems have multiple components that can fail without affecting the availability of your data
