Name-based virtual hosting allows multiple websites to be hosted on a single server using a single IP address. To set this up, Apache must first be installed on the system. Virtual host files are then created for each domain and enabled in Apache's configuration. The host files on local and remote systems must also be edited to resolve website names to the server's IP address. Potential issues that could arise include problems with network interfaces, updating, installing Apache, or restarting Apache when hosting multiple sites.

Dedicated, managed, colocation, and more All variants of servers.pdfJames Brown
If classic web hosting is no longer sufficient to store data in the cloud, it's time for your server. These come in several sizes, from the tower server under the office desk to the distributed data center, which bundles servers in several locations into a huge data center. But servers do not only differ in mass, size, and scope - there are also different variants slumbering under the housing of a server host. No wonder data centers offer more than just one product.

The document discusses the benefits of bare metal clouds compared to virtualized clouds. Bare metal clouds provide dedicated physical servers to individual tenants, avoiding many of the performance limitations of virtualized clouds like inconsistent performance due to resource oversubscription. Bare metal clouds also allow for complete hardware customization and isolation of workloads, which can help meet regulatory compliance requirements. While virtualized clouds are convenient, bare metal is presented as a better option for applications that require high and consistent performance, like large databases, as well as for matching an on-premises environment without performance compromises.
Virtualization allows multiple operating systems to run on a single hardware system by abstracting the physical hardware resources. It involves separating resources from the underlying hardware or operating system using a hypervisor. The main types of virtualization are server, desktop, application, network, and storage virtualization. Hypervisors manage the virtual machines and come in two types - native/bare-metal hypervisors that run directly on hardware and hosted hypervisors that run within a traditional operating system. Virtualization provides advantages like efficient hardware utilization, increased availability, easier disaster recovery, and energy savings. Popular virtualization software includes Microsoft Hyper-V, VMware Workstation, VirtualBox, and OpenStack.
The Future of Computing: Exploring the Potential of Virtualization ServerFredReynolds2
Virtualization Server may be a viable option if you want to reduce IT expenditures while maximizing your current IT infrastructure’s resources. This method of deploying multiple server applications on a single physical system has gained widespread market acceptance and is proving quite advantageous for small and large businesses.
A private cloud differs from a virtual private server (VPS) in many ways, including the cost that is involved and the location of the hardware, among other differences.
The document discusses the benefits of virtual servers compared to physical servers. Virtual servers use less power and IT staff can manage them like physical servers to run day-to-day operations. There are different types of virtual servers like public nodes, private nodes, and baremetal servers that can fit a company's needs. Benefits of virtual servers include improved security, flexibility, and powerful hardware and software infrastructure at a lower cost than physical servers. The document encourages readers to switch to virtual servers by contacting the company for a free consultation.

It then discusses the benefits of cloud computing for organizations, including reducing costs, improving scalability and agility. It also covers the main cloud service models of IaaS, PaaS and SaaS. The document concludes with an overview of common cloud products and services, deployment models of public, private and hybrid clouds, and a quick recap of the key topics.
The document discusses various cloud computing deployment models including public, private, virtual private, community, and hybrid clouds. It provides an overview of the key characteristics of each model such as ownership, ease of setup, scalability, security, and costs. A public cloud is fully managed by a third-party provider while a private cloud is owned and operated solely by the organization. A hybrid cloud combines multiple cloud models to provide flexibility to meet different business needs.
Cloud computing provides convenient, on-demand access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort. It provides an abstraction between computing resources and their underlying technical architecture, enabling flexible network access.
VDI allows organizations to virtualize desktops by running them as virtual machines on centralized servers rather than individual physical machines. The document discusses implementing a VDI solution for the City of Hallandale Beach. It estimates that deploying an initial 50 VDIs would cost around $90,000, with additional costs to scale up to 350 VDIs. While VDI provides benefits like easier management and mobility, the costs include new storage, software licenses, thin clients, and implementation fees. ROI is not expected until year 5 due to upfront infrastructure investment.

2. Introduction
If you are an IT professional, you probably know that choosing the right hosting
infrastructure can make or break your IT backbone. At one point in your career, you will have
to make the decision whether to use hypervisors or bare metal servers.
Both options will get the job done albeit differently. Each has its own unique characteristics
that cater to different needs in the market.
A good understanding of how both infrastructures operate places you and your company at a
better position to deploy the right strategies as far as hosting is concerned. To help you make
an informed decision, we have put together a guide that explains hypervisors and bare metal
in detail including their features and associated pros and cons.

4. What is Bare Metal?
Bare metal refers to a physical server or tenant environment ideal for a single person or company.
With this model, the owner of the metal server is virtually the only one with access to the server.
Its working principle resembles that of a dedicated server where the operating system can be
installed onto the physical server without the need for a hypervisor overhead. On top of its
exemplary performance, bare metal has the ability to support varied operating systems, even
hypervisors.
Bare metal servers often find use in workloads that require a high amount of processing power
and those that are latency sensitive. For this reason, these servers are excellent for projects that
demand a continuous amount of resources. Bare metal servers have impressive speeds therefore
utilized for workloads that need a fast turnaround.
The actual term, “bare metal” is primarily used to create a distinction between a physically
dedicated server emanating from a virtualized environment and the array of modern cloud
hosting strategies. Within any given data center, bare metal servers are not shared among
multiple clients.
5. Features of Bare Metal
Single tenant environment: Bare metal servers cater to one client and cannot be physically
shared with other customers. This, of course, can change if the clients decided to run a
separate virtualized environment apart from it resulting in the creation of a multi-tenant
environment.
Security: When it comes to security, nothing comes close to dedicated single tenant servers.
Since each server caters to one client, security breaches can only be witnessed if there was
hacking.
High processing power: Compared to all solutions in the market, bare metal servers can
handle more data.
Customization capabilities. As the sole owner of the server, you can play with all the
customization options at your disposal. From the configuration stage, you can select the
appropriate component including hardware resources, software, panel add-ons and so on. You
can even throw in a hypervisor into the mix.
6. What Is A Hypervisor?
A hypervisor is an operating system with the ability to create virtual machines (VM) inside a bare
metal infrastructure. With hypervisors, an operating system such as Ubuntu, Windows, or Debian is
directly installed on the server after which apps run natively within the OS. When a hypervisor and a
bare metal server are both installed on the OS, the user can play the role of a manager and create
virtual machines on the server.
The hypervisor’s purpose is not to run native applications but to virtualize workloads into isolated
virtual machines. This concept allows for enhanced reliability and flexibility of virtualization.
Hypervisors are fundamental components in the IT backbone because they make it possible for you to
have a range of virtual machines all functioning optimally on one piece of computer hardware.
Hypervisors were introduced in the 1960s but it wasn’t until the introduction of Unix and Linux that
they surged in popularity. These two operating systems heavily utilized hypervisors to expand their
hardware capabilities, improve reliability, control costs, and enhance security.
7. Features of Hypervisors
Uses virtual machines: Hypervisors use the virtualization technology of dividing bare
metal servers into private servers (VPs)
Horizontal scalability: Ideal for situations that demand horizontal scalability and pure
performance such as high-traffic websites and cloud software
Advanced Virtual Server Security: Include more features tailored to secure the system
and the virtual machines. For instance, they have software acceptable features that guards
against unsigned software finding residence in the system. They also have integrated
firewalls that eliminate the need of IP tables and utilize set of rules to define every port of
access. There are enhanced auditing and logging features that track every activity in the
system in order to prevent malicious activities from being erased or hidden. What’s more,
they also come with Active Directory Integration that authenticates users who are trying
to aces the virtualized servers. The only thing that users need to know is the fact that all
these security features may not benefit you that much if you don’t deploy and configure
them according to the recommended or proper security guidelines.
8. Advantages of bare metal
As a single tenant server, bare metal resources belong to you alone. This means it can only
cater to one client on the server. However, when one server is extremely overloaded with
requests, system administrators can increase resources by adding hardware. A bare metal
environment is ideal for a wide range of workloads particularly those that require access
management and granular resource with an ability to scale and maintain high levels of
security.
There are several advantages that make bare metal one of the most preferred hosting
infrastructure in the world of information technology. These include the following:
Security and isolation: Baremetal servers are security-sensitive. Organizations and
individuals alike can create a physical separation of resources. Although security is a
complex and broad terminology in cloud computing, using a bare metal server over other
hosting options enhances security substantially.
9. More processing power: Thanks to the limited access offered by bare metal servers, no
one can tamper with your project’s stability meaning your server will have higher
processing power.
Keeps costs predictable: Bare metal hosting servers can do a number on your wallet but
you can predict this cost since it is billed on a monthly basis. You can also opt for other
billing options such as hourly or weekly plans but the bottom line is that you will know
ahead of time how much you are expected to pay for using hosting servers.
Better service: By eliminating the “noisy neighbor syndrome”, you get a better quality of
service. Technically, a client can hold someone responsible if something wrong on the
system.
Flexibility: With bare metal, server configurations can be quite precise. You can combine
both hypervisors and bare metal servers for enhanced performance.
10. Lower overhead costs: Compared to virtualization platforms, bare metal servers incur
less overhead. The reason is that hypervisors utilize the server’s processing power on a
higher scale. Less overhead means increased speed and improved responsiveness. Bare
metal also gives room for more hardware customization which further enhances speed
and responsiveness of the system.
An affordable solution for data transfer: When it comes to outbound data transfer, bare
metal is always the most cost-effective option on the table. You can get several free data
transfer terabytes on certain dedicated servers which is not the case with other virtualized
environments. However, always keep in mind that these scenarios are heavily dependent
upon the offers in question. Also, there’s never any guarantee of partnership.
11. Disadvantages of Bare metal
Like all hosting infrastructure options, bare metal has a few disadvantages:
Instance limitations: When compared to virtualized instances, bare metal servers have
restrictions regarding the types and sizes of instances available.
Backup challenges: Hypervisors capture snapshots of the VM’s memory space allowing
for ease of backup. Bare metal servers don’t have this feature. Duplicating machine
images to be used as the backup and can be quite difficult to do. Additionally, bare metal
doesn’t support recovery from tape drives unless the tape drives and the BMR software
are from the same manufacturer.
Complexity: Bare metal processes can be intensive often relying on a third party
operating system to make configurations.
12. Advantages of hypervisors
What if you don’t have the luxury of being a single tenant as in a bare metal model? Perhaps
you handle a dynamic workload and need to utilize resources round the clock. Hypervisors,
too, have quite a huge number of benefits particularly for workloads that need to be run and
spun for a relatively short period of time before turning them off.
Quick scalability: If you need more server space, a hypervisor can easily grant you
additional servers in no time.
Ease of backup: Virtual machines allow for a smooth and seamless backup protection
compared to traditional applications. The process of securing a backup is complicated and
time-consuming hence can cause serious downtime. With VMs, snapshots of data can be
captured and saved in record time making the process easier and manageable.
13. Improved mobility: The VM’s structure has been designed in a way that it operates
independently separate from the underlying hardware. This enables it to have the ability
to roambetween local and remote servers that have an abundance of resources.
Optimization of hardware: Hypervisors have the ability to optimize hardware to a
greater extent. It allows virtual machines to run on their own by dividing resources into
separate entities. In addition, with virtualized servers, hypervisors make VMs super
mobile to a level that the underlying hardware is rendered irrelevant.
Security: Virtual environments are quite secure too. Even if the virtual instances haven’t
been physically separated, they are technically isolated from each other. Sure, they may
be on the same server but they have no knowledge of each other. So yes, the noisy
neighbor effect may be witnessed but the hypervisors are secure.
14. Disadvantages of Hypervisors
Some of the reasons some people shy away from using virtualized environments include the
following:
High implementation cost: Creating a virtual environment requires the purchase of both
hardware and software. Other times, devices may need to be manufactured, developed or
purchased in order to implement the infrastructure.
Availability issues: People and organizations who utilize virtualization often worry about
what will happen to their data in the event that their assets are unavailable. If this were to
happen, the organizations might struggle to maintain their positions in the industry. There’s
also the issue of third-party providers making the control of data almost impossible.
Requires cohesiveness of all links: Being the sole tenant means you are in full control of
your operations. With virtualization, you don’t have such control because there are quite a
number of links required to work seamlessly to achieve one goal. If one of the links is
compromised, the entire server will not function optimally.
15. Bottom line
When all is said and done, there’s no straight answer to the question of which hosting infrastructure to
employ for your organization. Every situation is unique. Every project has a different set of
requirements. Both bare metal servers and hypervisors have their pros and cons; it all boils down to
what your organization needs at the time.
Bare metal servers offer all the performance benefits of physical dedicated servers without the contract.
They cost way less than virtualized environments, have better speeds, higher processing power and have
better flexibility. If your business involves collecting vast amounts of data over a short period of time,
then you certainly want to go the beta metal servers’ way.
Hypervisors, on the other hand, are great if you are not after the elite performance displayed by bare
metal servers. If your goal is to utilize resources and consolidate infrastructure in one computer
hardware but still achieve high levels of performance, virtualization is definitely the best option for you.
With virtual environments, you can enjoy a high latency, reduced overall costs, mobility and the ability
to scale up and or down depending on the requirements at hand. Still, you can create a hybrid solution
that ensures you get the best of both worlds and ultimately maximize your RIO.
