“Server”, a term that most of us have heard frequently, has become an important IT component in the infrastructure of most enterprises these days as businesses rely heavily on technology to carry out their operations in this global business world. Now, what exactly is a server?
A server can either be software or it
can be a hardware device, which is meant to accept and then appropriately
respond to requests that are made over the Internet. Devices that generate
requests and receive servers’ responses are known as clients. Functionality,
which is known as a service, is provided by servers (hardware or software) to
these clients (devices or programs). The client-server model is used for this
purpose. Servers can be of various types, such as print servers, database
servers, file servers, mail servers, application servers, game servers, proxy
servers, web servers etc.
Let us take the example of web servers to further understand the role of a server. Web servers are used and provided by web hosting companies for storing the files of websites in order to deliver the service of web hosting. Web hosting is the service that renders different websites accessible over the Internet. When the files of websites that are stored on web servers, are delivered over the Internet, to the Internet connected devices of users, then websites become accessible to those users.
A web server essentially caters to
accepting and fulfilling the requests of clients with regard to the content of
websites (images, videos, HTML pages etc.). The usual “clients” of web servers
are browsers or mobile applications. The requests that are generated are in the
form of Hypertext Transfer Protocol messages (HTTP) and the web servers’
responses to these requests are also in the form of HTTP messages. In the
context of web hosting companies, which provide these servers, the most
competent web hosting service providers are referred to as the “Best VPS Hosting Company”, the
“Best Linux
Dedicated Hosting Company”, the “Top Cloud Hosting
Company” etc.
Servers, along with other essential
network equipment, are usually kept in a glass house or a closet. This is meant
for isolating these important IT resources from unauthorized access. Servers
that are not hosted on-site are present in data centers that make these servers
available for use.
It is essential for servers to remain
functional at all times because these provide such services that are required
constantly. Enterprises use servers for many functions, which include but are
not limited to hosting websites, applications, emails, data storage etc.
In this blog our focus is on VPS
(Virtual Private Server) and dedicated servers. These are two types of servers
that are used by web hosting companies for the purpose of web hosting. VPS
hosting involves the use of VPS and dedicated hosting involves the use of dedicated
servers. Let us elaborate on these two types of servers, and shed light on
their differences.
VPS
VPS
is the abbreviation for Virtual
Private Server. It is a type of server that uses virtualization technology to
ensure that every user of a VPS has access to dedicated (private) resources
that exist on a shared server hosting multiple clients. In a Virtual Private
Server, multiple clients utilize the isolated instances on the same parent
server. A VPS delivers enhanced security, performance and stability at a much
lesser price than that which is needed for renting an entire server and its
resources (dedicated server). Hence, a VPS offers one of the best solutions to
those whose requirements have exceeded that which could be effectively catered
to by shared hosting but are not at that level which requires them to invest in
a dedicated server.
A Virtual Private Server is capable of
successfully emulating a dedicated hardware by mimicking virtually a dedicated
server’s environment within a shared server, which is called the parent
server/host. In this way, it offers functionality similar to that of a physical
server. By virtue of being software-defined, a VPS can be created as well as
configured easily. In it, virtualization technology is used for delivering
dedicated resources to the virtual servers that exist within the host/parent
server. A VPS runs its own copy of an operating system. The multiple virtual
servers that exist within a parent server remain separated from each other.
Software called Hypervisor is used in order to implement a virtual layer atop
the OS (operating system) for segmenting the virtual servers. This segregation enables
each VPS to have its own OS and software installed, resulting in the creation
of individual private servers. The installation of custom software and the
creation of isolated development environments are enabled by a VPS. It aids in
isolating multiple digital service offerings. A VPS can either be managed or
unmanaged, when it is availed from a service provider.
Dedicated
Servers
A dedicated server is a type of a server,
wherein the entire server and its resources are used by a single tenant. This
type of hosting service is known as dedicated hosting or single-tenant hosting.
In it, the user has exclusive access to all the resources of the server, which
are not shared with any other user, as the entire server belongs to a single
entity. Hence, one is able to configure it entirely based on one’s
requirements. A dedicated server delivers enhanced speed, flexibility and
security and lets its user have full control over the server set up, which
includes hardware configuration as well as options for custom software.
Dedicated servers are known to deliver
the highest levels of performance and present one of the best solutions for
business critical applications, revenue-generating online stores, enterprises,
websites that need enhanced security and customization, experience a lot of
traffic, and/or those sites that anticipate rapid growth.
Conclusion
Virtual Private Servers and Dedicated
servers, both are very efficient types of servers and opting for either of
these servers depends on one’s requirements and budget. Availing a dedicated
server is usually more expensive than availing a VPS but in a dedicated server
one has total control over the physical hardware and the server’s software, and
it offers enhanced speed and security. Unless one has the requirement for a
dedicated server in particular, a VPS proves to be an extremely viable
alternative.
