It is important to ensure your company’s infrastructure is capable of handling the workload and providing uninterrupted business operations when starting a new company. Depending on your business needs, you can choose either a virtual server, physical server or combination of both. The differences between physical servers, virtual servers and cloud servers can be better understood by examining each of them separately.
Physical Server: What Is It?
Physical servers are hardware devices. It has the typical components of a computer, such as a motherboard, memory, CPU and so on. A physical server is often called as a “bare metal server” because the physical hardware is integrated directly with the operating system. In a physical server, one OS may run in one instance, whether that is Linux, Windows, or another exotic OS
Virtual Server: What Is It?
The function of a physical server is emulated by a virtual server, which is an abstraction of that server. One of the main advantages of this technology is the possibility of running multiple virtual servers on one physical server.
Physical Server vs. Virtual Server vs. Cloud
01. Performance–
There is no competition with physical servers because they consists of dedicated resources such as CPUs, storage, memory and other networks. Therefore, physical servers generally perform better overall and possess more power and efficiency and have no performance issues. On the other side, the use of multiple virtual servers makes them prone to performance issues since they compete for the same computing resources. As a result, stability and efficiency may be compromised.
02. Requirements for space-
There is a larger footprint and space requirement for physical servers. In contrast, virtual servers need no space requirement since they are based on physical servers. Multi-hosting makes virtual machines space-efficient since they can be hosted on a single physical host
03. Management-
Manpower and skills are required to manage physical servers. Physical servers also take a long time to repair if they fail or crash. A virtual server, on the other hand, is much easier to manage and can be easily recovered when it fails. Also no manpower or skills are required to run virtual servers.
04. Security-
Virtual server environments make it easier and simpler to configure and manage security. Also, the universal security model can be used to protect virtual servers. A physical server, on the other hand, requires you to create a protection system for each server based on the capabilities, resources, and data sensitivity located on that server. Consequently, a multi-server IT infrastructure becomes more challenging and resource-intensive
05. Costs-
Maintenance and management of a physical server are time-consuming and expensive. Virtual machines, on the other hand, are cost-effective due to their ability to optimize capacity through an even distribution of computing resources.
06. Portability-
Changing data centres and moving your physical server is a time-consuming and potentially dangerous process. Everything you’ve saved here has to be replicated onto another disc or removable media. Virtual machines, however are hardware-independent and can be moved between physical servers and across virtual environments without requiring any hardware changes.
Cloud servers are basically virtual servers. Virtual servers run in a cloud computing environment and are therefore called cloud servers. The cloud computing platform delivers it, hosts it, and allows remote access via the internet. A virtual server can also be called cloud servers. A cloud server comes with all the software it needs to function and can be run independently
Physical server is best for handling massive amounts of data and traffic whereas on the other hand, a virtual server is a good option for organisations of all sizes that need flexibility and scalability. Decide which server is most suitable for your business based on your needs and demands by analysing your business requirements
