Difference Between Bare Metal Servers and Virtualization
Feature |
Bare Metal Servers |
Virtualization |
---|---|---|
Need of Hypervisor |
There is no need for hypervisor, runs directly on physical hardware |
There is a need of hypervisor with abstracts the hardware part and manages |
Performance |
Higher performance as the resources are physical and mostly used by a single user or a single organization. No sharing or tenant. |
Slightly low performance as compared to Bare Metal Servers, as there is a hypervisor involved and mostly the resources are being shared with many people which causes lower performance, |
Isolation |
It is isolated from other servers as they are physical in nature and mostly one user or organization use one server. No tenant or sharing is possible |
Resources are being shared between various different users / tenants. No isolation at all |
Resource Utilization |
Resources are being used by a single user or single organization. So sometimes there is a chance that all resources might not get utilized entirely as it varies based on different applications running on the server. |
As the resources are being shared amongst various different users, the chances are very low that the resources will be left unused. |
Scalability |
Scalibaility is little bit costly as compared to virtualization as physical elements should be bought and installed in the server manually. |
Scalability is much more easier as there is no need to install physical elements in the server manually. Users can simply rent more resources which will cost them lesser than bare metal servers. |
Cost Efficiency |
Bare Metal server is costly to setup for first use, but is cost effective in long term, when the applications that are being deployed required the same configuration. |
It is much more cost effective as there is no need to buy the physical elements entirely, users can just easily rent them and use them. |
Deployment Time |
Longer deployment time due to physical installation and setup. |
Much more faster deployment time as virtual machines can be rapidly setup. |
Security Isolation |
Higher security isolation as the servers are not being shared publicly. |
Lower security isolation as anyone can rent the servers as they are available publicly. |
Bare Metal Servers | Networks in System Design
In today’s rapidly evolving world of technology, the unending desire for Optimal Performance, Reliability, and Scalability in System Design is constant. One of the most important choices the developers had to make was the underlying infrastructure of those systems.
