Businesses are now expected to run continuously, which means that even the smallest disruption to business operations can have serious consequences. Therefore, ensuring business continuity in the event of an accident should be one of the top priorities of any organization.


Companies need secure, reliable and high-performance solutions to process and store their applications and data. When comparing different hosting services, you are likely to see a variety of options to choose from. The choice between physical servers and virtualization is often challenging due to the complex business requirements and the pros and cons of each service.


When you consider the costs of administration, management, processes, and the server itself, the cost of physical servers is high. Running and maintaining physical servers increases a company monthly costs as more servers are needed over time.


You can also associate a dashboard with infrastructure metrics: Azure and AWS. This is done in order to see everything in one centralized place. It is designed to work with multiple actions for monitoring and managing virtual machines. Therefore, there is no need to switch to separate tools to degrade performance for Hyper-V and Vmware.


This means you do not need to go into the hypervisor to make configuration changes to optimize performance. Try VMAN free for 30 days.


There are many benefits to using virtual hardware instead of physical hardware. Setting up a virtual server should be something every business should consider as it grows. If you have 1 server, then it is not worth virtualizing, but the investment makes sense as you start adding more servers.


Required redundancy


The problem with virtual servers is that they still depend on the underlying physical machine. If a physical server experiences a mechanical failure and there is no redundancy, multiple virtual servers will be affected. This can lead to serious financial implications in the event of prolonged downtime.


Certain types of workloads are not critical and may not need to be deployed virtualized. You may have certain data assets that do not contain payment, health, or other regulatory information. In these cases, the right choice might be to use the underlying physical server that you already have.


Many organizations are choosing to gradually migrate their workloads to virtualization. If that is your intention, please inform your vendor of the migration tools they have and discuss application compatibility.


Virtual Private Server is A VPS is slightly different from a virtual VPN server, with the main difference being ownership. Simply put, virtual servers are hosted on servers owned by a VPN provider, while a VPS leases space from a shared data hosting provider.


However, managing a virtual server environment requires a level of knowledge and specialized skills. It is important to ensure that your team members are competent enough to manage the virtual infrastructure.


What is a physical server?


A physical server can be defined as a regular computer. They are more than what you might think of when you think of a desktop computer though. They function in much the same way, albeit on a business class scale. Physical servers are powerful computers stored in the data center for business applications that run operating systems and applications from internal hardware resources. These resources include RAM, processors, hard or solid state drives, network connectivity resources, and more that support the performance of physical servers.


Setting up a virtual machine server can seem daunting. With the range of virtualization tools available, you can install and configure virtual machines faster than you think. Once you find the hypervisor you like. Make sure you have a separate tool to monitor and optimize virtual machine performance at all times. This will help ensure that performance issues are resolved and the best possible service is provided to end users.


Physical or virtual server security


<>pThe security of your physical or virtual servers is highly dependent on configuration, staff knowledge, and environment. As with risk mitigation, these factors can vary significantly depending on the requirements and internal resources of the company. For many organizations with minimal budgets or hardware, moving to virtualization can provide a security benefit.


Cloud can also refer to cloud computing, where multiple servers are linked together to distribute the load. This means that instead of using 1 powerful machine, complex processes can be distributed among several smaller PCs.


According to statistics, more than 50% of enterprises plan to use storage virtualization and application virtualization in 2021. After a worldwide pandemic, this number is likely to skyrocket.


Another reason to run a physical server is the need for hardware that cannot be virtualized. Some components, such as adapters and PCI interfaces, cannot be added to a virtual machine. And of course there are non-virtualized platforms like IBM AS / 400 or Unix hosts.


Virtual machines are more common than they used to be, and every administrator in the enterprise will have to deal with configuring virtual servers and virtual machines. By following best practices, you can help keep your enterprise computers running at levels of functionality and performance.


What is a virtual machine server?


Virtual machines (VM) are computing instances created by a program running on another machine; they do not physically exist. The machine that creates the virtual machine is called the host machine and the virtual machine is called the guest. You can have many guest virtual machines on one host machine.


Virtual server is a server created by the program. You can have many virtual servers running on 1 physical machine. They are completely separate from each other and from the physical machine.


First, you can save money by switching to virtual servers instead of physical hardware. When you host multiple virtual servers on 1 physical machine, you can allocate resources to each virtual machine and let the machines use the resources they only need at the moment. This means that you can more easily distribute the resources of a single physical machine with multiple virtual machines. units.


When one virtual machine uses fewer resources, the other virtual machine will be able to use the space. This will improve efficiency and reduce resource overhead that can be caused by over-provisioning of resources on physical machines. When you have fewer physical machines, you save money by reducing the amount of physical storage space for your servers. You can also save time when initializing and de-initializing machines, replicating machines, backing up and restoring data. All processes can be performed quickly and easily with virtual machines, much faster than with physical servers.


How to set up a virtual machine server


It is easy to create and configure a virtual machine server. Therefore, their use has become widespread. Setting up virtual host machines is the first step as the main limitation on the number of virtual machines you can install on 1 device is hard disk space. The capacity of the physical host machine matters for configuring virtual server machines and for determining how much you can create. Because each virtual machine will also need RAM and CPU. Make sure you have enough hard disk space and a processor with the highest possible number of cores.


All servers today are focused on multicore, so they should be able to host virtual machines. Get as much fast RAM as possible. CPU resources can be reallocated, but not RAM. You should also think about the storage you might need if you do not have a SAN for the virtual server images. In this case, the host server will need enough disks to store this storage. SATA drives or SAS drives are best suited here.


If you have physical hardware with adequate resources, you can use virtualization software to configure the virtual machine server.


Machine virtualization tools


There are many well-known tools out there: Hyper-V, VMware, VirtualBox, or Citrix XenServer. The one you choose will depend on which operating system you are using, what you want to virtualize, as well as cost and functionality. These programs are called hypervisors.


Some hypervisors are installed directly on the hardware are bare-metal hypervisors. Others are installed on the pre-existing operating system installed on the host machine - hosted hypervisors.


The bare metal hypervisors and associated virtual machines can run slightly faster. They are generally more difficult to configure and use than a hosted hypervisor. After installing one of these tools, you can follow the instructions on the hypervisor itself to configure and provision the virtual server. Hosted hypervisors are like any computer application because they have an installation wizard with simple instructions.


How to set up virtual machines


Setting up virtual servers will also take a little time. Check the default values ​​for the virtual machine and make sure they are appropriate for your purposes. You will need to choose which guest operating system you want to run, where the virtual machine files will be stored, and what types of network connections you want to configure for the virtual machine. Then you need to decide whether to allocate all disk space for the virtual machine when it is created. You can configure 3 types of virtual machine resources when the machine is created or after it is created: the hardware it has access to, power management and operating system settings, and resource configuration: CPU configuration, hyper-threading, disk settings, and memory.


Virtual Machine Configuration Management Software


To tune your machine for optimal performance, ideally you should be using software that is capable of managing your virtual machines. Recommend SolarWinds Virtualization Manager - VMAN. VMAN provides complete visibility into your virtualization environment, including Hyper-V and VMware environments. VMAN can work with on-premises, cloud or hybrid environments and analyzes how your virtual machines are connected to applications, servers, and storage infrastructure. This provides complete control over the virtual architecture and ensures that you can identify problems no matter where on your systems they occur.
