Bare Metal Servers and Virtual Servers both have their unique advantages and so the decision to select one of them depends largely on factors such as performance, scalability, flexibility, security and cost.
Bare Metal- A bare metal server is nothing but raw piece of hardware. It is a single tenant physical server that is completely dedicated to a single customer. Customers can choose it when they have data intensive workloads that prioritize performance and reliability. Additionally, in order to gain high performance computing, graphical processing units (GPUs) can also be pressed into service to work in conjunction with the bare metal server.
Advantages of bare Metal Server-
- Better Security and Privacy- Businesses restricted by compliance measures can stay assured that nobody else will be able to access data on the server.
- High processing power- Since, the resources are not being shared, the hypervisor layer of a virtual server is not required, resulting in greater processing power.
- Gain consistent performance- Resources of a bare metal server remain consistent and so users will never observe peaks and troughs.
- Complete Control- With a bare metal solution, users can isolate a server’s physical resources to gain full control.
Virtual Server- A virtual server is a server that shares hardware and software resources with other operating systems, unlike dedicated servers. Ideally speaking, virtual server mimics dedicated server functionalities. This feature will eliminate the implementation of multiple dedicated servers, and instead will allow the deployment of several virtual servers implemented on one server. In this virtual environment, each server is designated a separate OS, software and independent reboot provisioning. Remember, that an overflow of virtual servers in a physical machine will lead to resource hogging. Also, if the deployed virtual server uses more resources than another, performance issues will erupt.
Advantages of a virtual server
- Virtual servers allow organizations scale up and scale down their server resources with the greatest of ease.
- Unlike bare metal, where resources could go underutilized or wasted, virtualization enables better server efficiency.
Which is best for your business?
In general, the server requirements for each organization are different. Therefore, choosing between a bare metal server and a virtual server becomes relatively straightforward. Bare metal servers are best suited to businesses that cannot afford any periods of downtime.
