Introduction

Cloud servers and dedicated servers each perform distinct tasks based on use-cases, and can be a challenge to determine which environment will satisfy the requirements that a business requires. we will compare the similarities and differences of a cloud server vs a physical server.

What Is A Cloud Server?

The concept of a cloud server is one that cover ups the physical limitations of a traditional workstation/servers setup. In the new paradigm, client data and other accessible resources are spread through multiple devices in different locations.

These devices are usually hidden from us by an “application layer” operating on those parent devices. Accessing your cloud server is done either via a “management portal,” which is an interface that gives you access to services on your cloud server, or via FTP (or a similar file transfer program).

What Is A Physical Server?

 The Theory behind a physical server is fundamentally different from that of a cloud server. Physical servers are the dedicated computers specifically purposed for private use.

These types of servers are usually hand-built hardware, arranged in a specific designed configuration and purposed to meet a particular goal for a business. They are extremely powerful and fully customizable in every way. In this you  will certainly be given privileged user access over the entire system and can access, install, and set up according to your own requirements. 

Features of Cloud Servers

- Your data is easily transferable between physical “parent” servers. Basically, the cloud service handles the processes that control storage and usage of data. Because there is an application layer working on the cloud server, your data can quickly and easily be moved among actual physical resources that make up the cloud infrastructure.

- Data redundancy and backups are also more easily achievable since copies of your data can be spread across multiple physical machines automatically without human intervention.

- The benefits of having your data controlled by an application layer running across multiple servers rather than a dedicated-to-you host are as follows.

  • A client can control the amount and allocation of resources used at any time.
  • A client can determine the exact amount of resources they want to purchase

- The  scalability of CPU cores, allocated RAM (memory), and disk space  can be easily increased/decreased as needed.

- Additional services that can be  provided are external file storage, load balancing, and databases can be added with a few easy clicks. 


- Since the virtualized operating system is part of a parent server that may be shared by multiple accounts, the risk of over allocated physical resources is increased due to additional              accounts on the parent.

- This could create poor performance for your application or site. These “noisy neighbor” concerns are inherent in most cloud-based environments and are considered one of the significant drawbacks of this type of infrastructure.

Features of Physical Servers

- Because the physical resources are dedicated to just this server, there is no “noisy neighbor” issue. This option ensures that you receive the full, undivided use of the hardware. i.e. all the    hardware is available for your utilization.

- Physical servers are configured with exact specifications in terms of the CPU type and speed, disk space, memory, etc. This  level of control allows for a custom-designed server to excel    at performing specific tasks you want to perform. Also  it provide for additional flexibility of configuration that may not be available in a cloud-based environment.

- Because a server can be dedicated to a unique set of tasks, additional hardware options (e.g., dedicated firewalls, routers, and switches) are available, which may not be available in a cloud-based system. This further increases the degree of customization your environment can employ.

- The single-tenant environment of a physical server is usually the most secure type of platform you can get. Because of the limited number of admin users and the increased permission     settings, there is less worry about attacks from “neighboring accounts” in a cloud platform that may be sharing the hardware environment.

- This circumstance also precludes any additional performance issues for your server. Also, there is less worry about a malicious user attempting to exploit the parent server. These limit         privileged access to the application layer running the cloud-based hypervisor system. 

- Changes to dedicated servers typically require some degree of downtime. Because there are no additional resources to be “unlocked” or enabled for your use during a hardware swap        any upgrades involve the physical modifications of the hardware itself.
