The demand for an appropriate server stems from the basic need to deliver high network performance. In line with meeting this primary requirement, the following details throw light on the difference between bare metal servers and virtual servers.
Bare Metal Servers
Also referred to as dedicated servers, this server deals with raw hardware. Also identified as a single-tenant physical server, such servers in line with their very name basically meet the tailor-made needs of a single user. These servers primarily come to use with data-intensive workloads that become the backbone for reliability and performance. There is a provision to include Graphic Processing Units (GPUs) which will work in tandem with the CPU of the bare metal server, thus leading to enhanced performance computing. The provision to opt for a private visualized environment is made possible along with the facility of a monthly billing plan as part of a budget-friendly customer-centric feature.
On the other hand, virtual servers can come as a perfect bet for enterprises eyeing on the characteristics of flexibility and scalability in their environment. Basically meant to build new applications on the cloud, these servers do their best in offering unknown computing needs.
The following are the two prominent scenarios which bring in the flexibility feature of virtual servers.
- A virtual server operating on a public node comes as the first scenario that brings in the concept of resource being distributed across multiple customers. It is a physical server that meets the demands of a multitenant environment.
- A virtual server which is running on a private node comes as the second option. This enables you to be the sole user of all the components of the physical server. Exclusively meant for your complete utilization, this is an option that will allow you to use up all the resources of the server. This can come with an hour-based or monthly billing plan as per the agreement.
Both these types of servers; bare metal servers and virtual servers can be created from scratch allowing users to create a template of their image to be stored in the SoftLayer library. Once saved, it makes it an easy job to load these on to your environment.
Here are the 2 types of images that can be captured and stored.
- Standard Images:
Such images are specific to virtual servers alone. Standard images can easily be captured from an operational virtual server irrespective of the operating system. Once captured, such an image can be used to create a new server.
- Flex Images:
Bare metal servers and virtual servers support flex images. However, it is important to note that flex images in contrast to standard images are compatible with a subset of operating systems.
Allowing users the ability to capture the image from a physical machine, such an image can then be used to create a new virtual server in line with the physical image.
Having enlisted the differences between these two types of servers, it comes as a wise move for organizations to give a deep thought about the components of their IT environment before zeroing on a particular option. This way, they will be taking a well-informed decision that is in line with the vision and mission statements of their organization.
