    Do you think that people make a difference between "Physical Dedicated Server" and "Virtual Dedicated Server"?
    How would you compare them ?

    Hi
    Physical dedicated servers are just known as dedicated servers and are large physical server machines placed in datacenters. They are very powerful performance wise and really secure as well. When it comes to virtuality, virtual dedicated servers are the VPS servers. They are dedicated to one user only and they are much safer and independent than shared servers. They are a much cheaper alternative to dedicated servers.

    I prefer Cloud dedicated servers if thinking on the line of Security. Because in a cloud environment lot people are responsible for the security whereas in a physical server only a guy or few guys are responsible.

    Server is a physical computer. Dedicated server means the server is dedicated to only one user. A server can be virtualized to host many more users. Virtualized dedicated server units are sold as VPS.

    As the name implies, a Physical Server (also known as Dedicated or Bare Metal server) is an actual tangible and physical server, that is, a big computer located on some place in the world that can be used for a customer/user to host stuff (be it web hosting, game servers, backup services, etc).

    A Virtual Private Server or VPS (sometimes referred as Cloud Server by some providers) is a virtual space, that is, a space created with software that includes OS, dedicated storage space and resources as if it were a physical server, but actually is like 'emulated' inside a real computer.

    The advantage of a Virtual server is that there can be many virtualizations on a same server, so it's cheaper than a real physical server, the disadvantage is that it shares resources and it may be slower than a dedicated server.

    A virtual private server is a process of virtually partitioning a physical server into multiple servers so that each virtual partition runs its own operating system and possess the appearance and capabilities of running its own dedicated machine. In other words, the actual hardware server is partitioned into numerous isolated environments.
    A dedicated server hosting as the name suggests reserves the entire server and its resources for a single website or organization.

    Web Hosting can be categorized into common type including virtual private server, dedicated server, cloud hosting and shared server hosting.
    Shared web hosting is one of the lowest cost as well lowest level of hosting solution available in terms of server performance, reliability and security, which abandons those web page owners and webmasters with serious hosting related requirements to look over other options available such as cloud hosting, dedicated server and vps hosting.

    Dedicated servers are used by those clients who wants to host their own websites or VPS. With Dedicated server you get the ultimate power to generate multiples of small physical servers/VPS to your clients. You get the full root access in your own hand. You can experience High quality, reliability, high performance and easy to customize things from WHM(root).

    You get the capability to go far beyond the resource limitations found in shared hosting. You can upgrade your server anytime.

    Whereas if we talk about Normal server or you can say VPS[Virtual Private Server] is very much similar to dedicated server in terms of specifications. The only difference is you get access to limited resources. Suppose if your server is getting heavy traffic you just can’t upgrade your server. For that you need to buy VPS with advance and high capacity resources and transfer the data in your old VPS. Though you have full access of your private server but still you have to dependent on the Root Server i.e Dedicated server.

    To be more clear i can say that dedicated server in itself is a whole “World” whereas VPS is just a small part of it.

    A Physical Dedicated Server refers to an actual physical server that is available in a data center. In hosting terminology, hosting providers give an entire physical server to a single client; it is known as Dedicated Hosting.

    As the name suggests, Virtual Dedicated Servers are virtual (not actual ones). Hosting providers logically create multiple virtual servers on one physical server and distribute it to their clients. It is called VPS(Virtual Private Server) Hosting.

    VPS is cheaper than Dedicated Server because you get fewer resources like RAM, disk space, Bandwidth, etc.

    To see the physical server vs virtual server differences, a closer look at all of their components is required.

    Performance

    This factor should be considered if your organization works with a large amount of data which needs to be constantly processed. Physical servers are far more powerful and efficient than VMs, due to the fact that VMs are prone to performance issues as a result of an overflow of virtual servers in a physical machine. Thus, a physical machine and a virtual machine, both having the same hardware and software resources and capabilities, cannot perform on the same level. If your organization runs operations which require the use of computing resources to the fullest extent, a physical server is the optimal choice.

    Management

    As for the management factor, VMs are much easier to maintain than physical servers. In case of server failure, it could take several days to restore a physical server to its original state. For VMs, the recovery process can be initiated in just a few clicks with the help of a previously-created VM backup. Moreover, a physical server must be closely inspected for any deficiencies and, if required, additional drivers should be installed and set up before it can be used. This is not the case with VMs as they are built upon physical hardware which is ready for use. Thus, VMs can be created and powered on in a few minutes’ time.

    However, managing a virtual server environment requires a high level of expertise and specific skills. Thus, make sure that the members of your IT team are competent enough to control your virtual infrastructure.

    Portability

    One of the major physical server vs virtual server differences lies in portability. You can easily move VMs across the virtual environment and even from one physical server to another, with minimal input on your part. This is due to the fact that VMs are isolated from one another and have their own virtual hardware, which makes a VM hardware-independent. Moving your physical server environment to another location is a more resource-intensive task. In this case, you will need to copy all data stored on the server to a removable media, transport the media as well as all hardware resources that you have to a new location, and then re-install all of the system components on a new server. Essentially, you will have to re-build a server from scratch.

    Scalability

    To expand a physical server environment, you need to buy additional hardware components, which can be very expensive, and go through a long process of installation and configuration. At the same time, a virtual server environment provides the option of on-demand scalability. A single virtual server can host multiple VMs at the same time, which can be added or removed with the click of a mouse. Your virtual environment can be scaled up or down depending on the growth of your business needs. In this case, you don’t need to buy additional hardware to ensure VM deployment. This is due to the fact that VMs running on the host share the same computing resources, which can be evenly distributed among all VMs. Thus, you can design an easily configurable environment which can carry out operations of any complexity levels.

    Capacity management

    Physical servers do not use their hardware and software capabilities to maximum levels, with their average production capacity being at 25%. Thus, a lot of computing resources are left unused, which isn’t cost-effective. On the other hand, a server hosting multiple VMs takes care of underutilized resources by distributing them among other VMs which need it most. This way, optimum capacity management is achieved.

    System recovery

    If the production site was hit by disaster, it is essential to quickly restore mission-critical data and operations so as to reduce system downtime and minimize its negative impact on business. It can take several hours or days to restore business operations running on a physical server. In this case, the disaster recovery (DR) process entails setting up a new physical server, installing an OS, setting up applications, and restoring critical data from backups.

    The DR process in a virtual environment is much simpler. You can restore the entire VM at a DR site with the help of previously created VM backups, resulting in almost zero downtime. To ensure that the DR process runs smoothly and your data can be promptly recovered if needed, consider installing third-party data protection software, such as NAKIVO Backup & Replication. An efficient solution can offer you a variety of reliable data protection options for a fraction of the price.

    Business continuity

    Currently, businesses are expected to operate on an always-on basis, meaning that even a minor interruption in business operations can lead to major repercussions. Therefore, ensuring business continuity, especially in case of disaster, should be one of the main priorities of any organization.

    When comparing physical servers and VMs, it becomes evident that VMs are more fault-tolerant. In case of disaster, the workload of your virtual environment can be transferred in a few clicks to another site, so as to ensure the minimum downtime. After the effects of the disaster have been mitigated and the production center has been restored, you can move the workload from the DR site back to the primary site.

    If a disaster has affected or destroyed your physical server infrastructure, the damage, in most cases, is irreversible.

    Security

    Security management is more easily configurable in a virtual server environment than in a physical one. With physical servers, you have to build a system of protection for each individual server, depending on its computing capabilities and resources and the sensitivity of data that it stores. This can be a resource-intensive task if your IT infrastructure is built upon 10 or more physical servers.

    On the other hand, a virtual server environment can be protected on the basis of a universal security model. Thus, security policies and procedures can be developed, documented, and implemented from a single pane of glass - that is, through the hypervisor dashboard.

    Costs

    Building and maintaining a physical server environment can be quite expensive. This is due to constant hardware and software upgrades, frequent system failures, and breakdown of computer components and equipment, which are difficult or even impossible to repair.

    At the same time, virtualization is considered a perfect option for enterprises which contain a large number of servers. A virtual server environment allows you to evenly distribute computing resources among all running VMs, thus ensuring capacity optimization for a minimal price. However, you should note that VM software licenses can be quite expensive as well. Depending on the size of the virtual environment, the price can be up to a few thousand dollars.
