What is Server and How Many Types of Server?

Are you wondering what a server is? Well, you are in the right place.

Choosing the right server is certainly difficult if you don’t have a clear idea of what exactly it is and what its functions are. In this guide I will explain the definition of server to you in the most explanatory way possible.

In fact, we will see what it is used for, how it works and what the various types are, so that you can have the elements to choose the right one for your needs.

Definition of full Server

Let’s now look at the definition of server. A server is a computer program or device that provides a service to another computer program and its user, also known as a client. In a data center, the physical computer on which a program runs is often referred to as a server. That machine could be a dedicated server or it could be used for other purposes.

The term server on the Internet usually refers to a computer system that receives requests for web files and sends them to clients.

In the client/server programming model, a server program waits for and fulfills requests from client programs, which may be running on the same or other computers. The application provided on the computer can act as a client with requests for the services of other programs and as a server for requests for other programs.

How does server work?

The term of server refers to any physical machine, a virtual machine or software that runs server services. How it works varies greatly depending on how it is used.

Physical and virtual servers

A server is simply a computer used to run server software. The differences with a desktop computer will be discussed in detail in the next section.

A virtual server is a virtual representation of a physical server. It has its own operating system and applications. These are kept separate from any other virtual servers that may be running on the physical server.

The process of creating virtual machines involves installing a lightweight software component called a hypervisor on a server. The hypervisor’s job is to allow the physical server to function as a virtualization host. The virtualization host makes physical server hardware resources, such as CPU time, memory, storage, and network bandwidth, available to one or more virtual machines.

An administration console gives administrators the ability to allocate specific hardware resources to each virtual server. This helps to drastically reduce hardware costs as a single server can run multiple virtual machines.

Software

A server requires at least two software components: an operating system and an application. The operating system serves as a platform for running server applications. It supplies access to the inherent hardware resources and provides dependency services on which the application depends.

The operating system also provides clients with a way to communicate with the server application. The IP address and the fully qualified domain name, for example, are assigned at the operating system level.

Server and desktop computer

There are both similarities and differences between desktop computers and server computers. Most servers are X86 / X64 CPU based and can run the same code as an X86 / X64 desktop computer. Unlike most desktop computers, however, physical servers often include multiple CPU and memory sockets for error correction. They also generally support more memory than most desktop computers.

Since server hardware typically runs mission-critical workloads, hardware manufacturers design servers to support redundant components. For example, a server might have redundant power supplies and network interfaces. These redundant components allow the server to continue operating even if a key component fails.

Server hardware also differs from desktop hardware in terms of form factor. Modern desktop computers often exist as mini towers, designed to be placed under a desk. While there are still some vendors offering tower versions, most servers are designed to be rack mounted.

These rack mount systems are described as having a 1U, 2U, or 4U form factor, depending on how much rack space they occupy: a 2U server takes up twice the rack space of a 1U.

Another key difference between a desktop computer and a server is the operating system. A desktop operating system may be able to perform some server-like functionality, but it is not designed or licensed to replace a server operating system.

Windows 10, for example, is a desktop operating system. Some editions of Windows 10 include Hyper-V, Microsoft’s virtual machine platform. While Windows 10 and Windows Server can run Hyper-V, the Windows 10 hypervisor is primarily intended for development purposes. Otherwise, the version of Hyper-V included with Windows Server is designed to run production virtual machines.

Although an organization can run a virtual server on Windows 10 Hyper-V, there are licensing issues to consider. Additionally, Windows Server Hyper-V includes resiliency features not found in the version of Windows 10. Windows Server, for example, supports failover clustering and virtual machine replication.

Likewise, the Windows 10 operating system can make files available to devices on a local network. However, Windows 10 was not designed for large-scale file sharing. Windows Server, on the other hand, can be configured to act as a full file server. In large organizations, a distributed file system can be created on an entire server farm in order to provide better performance, scalability and resilience than a physical server would be able to provide on its own.

The Various Types of Servers

Servers are often classified according to their purpose. Some examples are the following:

  • A web server is a computer program that hosts a website and serves required HTML pages or files. In this case, a web browser acts as a client.
  • An application server is a program on a computer on a distributed network that provides business logic for an application program.
  • Proxy server is software that acts as an intermediary between an endpoint device, such as a computer, and another server from which a user or client requests a service.
  • A mail server is an application that receives incoming e-mail messages from local users – people within the same domain – and remote senders and forwards outgoing e-mail messages for delivery
  • DNS server: the domain name server is very important because it is used to convert an IP address into the domain name, so that you can use for example bcloud.com.bd instead of a series of numbers that you would never remember.
  • FTP: FTP servers move files using File Transfer Protocol tools. FTP servers are accessed remotely using FTP client programs, which connect to file sharing on the server, via the server’s built-in FTP capabilities or with a dedicated FTP program.
  • A virtual server is a program running on a shared server configured in such a way that each user appears to have complete control of a server.
  • A file server is a computer responsible for storing and centrally managing data files so that other computers on the same network can access them.
  • A database server is responsible for hosting one or more databases. Client applications run database queries that retrieve or write data to the database hosted on the server.
  • A print server provides users with access to one or more networked printers or printing devices. Serves as a queue for print jobs submitted by users. Some print servers may prioritize jobs in the print queue based on the type of job or who sent the print job.

Server components

Hardware

Servers are made up of several different components and subcomponents. At the hardware level, they typically consist of a rack-mount chassis containing a power supply, a system board, one or more CPUs, memory, storage, a network interface and a power supply.

Most hardware supports out-of-band management via a dedicated network port. Out-of-band management allows for low-level management and monitoring of the server, regardless of the operating system. Out-of-band management systems can be used to remotely turn the server on or off, to install an operating system, and to perform health monitoring.

Operating Systems

Another component is the operating system: Windows Server or Linux, an operating system such as a platform that allows applications to run. The operating system provides applications with access to the hardware resources they need and enables network connectivity.

The application is what allows the server to do its job. For example, a database server will run a database application. Likewise, an email server should run a mail application.

Choose the Right Server

There are many metter to consider when choosing a server, including virtual machine and container integration. When choosing a server, you need to evaluate the importance of a few features based on usage.

If the server relies on the internal memory, disk type and capacity are also essential because it can significantly influence input/output (I/O) and resilience.

Many organizations reduce the number of physical servers in their data centers as virtualization allows fewer servers to host more workloads.

With the advent of cloud computing, the number of servers required to host an organization’s site has also changed. Packing more capacity into fewer containers can reduce overall capital expenditures, data center space, and power and cooling demands.

What is bcloud hosting?

The bcloud hosting (from the English “cloud”) provides storage space, computing power, and executable software in a locally located computing center. The English term underlines that the server used for this purpose is not directly visible but hidden as if it were behind a cloud.

Cloud: the term cloud is the abbreviation for cloud computing. A cloud is made up of remote servers accessible from anywhere and via a safe and secure Internet connection.

Today, efficient company management requires flexible adaptability of the computing capacity to use it without problems in case of need, even by external collaborators. This flexibility also makes it possible to adapt the reserved service as needed. A rigid, internal IT structure, on the other hand, constrains personnel and financial resources. Moreover, in some cases, it may not be able to keep up with changing needs. A freely scalable alternative may therefore be the best choice.

This evidence first led to the development of a memory space separate from the computer in the workplace. This space is outsourced to the cloud, the so-called (data) cloud. The storage space and programs used in the cloud can adapt to business needs, called scalability.

The history of cloud computing began as early as the 1950s. In the age of the Internet, the opportunities for cloud computing have become ever more significant. The trend will continue as new Internet security standards have significantly reduced what had previously been fears about the use of cloud services. Nearly two-thirds of the world’s data is expected to be stored and managed in a cloud solution by 2025.

What do you do with a cloud?

Using a cloud, data, programs and computing capacity are transferred to external storage spaces for the user’s workstation. For this purpose, several remote servers are made available. Those who take advantage of the related cloud offers can rent storage space and make use of the computing power, reproducing in principle the complete infrastructure of a data center. In this way, companies and private users can, for example, use programs directly with the browser without having to install them locally. Others use the cloud only as additional storage. Cloud computing is also famous for teamwork – many collaboration tools work on a cloud basis.

Access is possible via an encrypted Internet connection. Each user must uniquely identify himself to have access to this memory space. The philosophy is similar to that of a corporate network, however the normal local distance between the workplace computer and the server is much larger.

The memory space’s size, the computing capacity, and the software to be used among those of the cloud provider are contractually established. Performance can easily be increased later, as the company does not have to invest in additional hardware or expensive software with regular updates. For private users, many services are also available free of charge.

In the cloud, the user saves the data and then retrieves them. Similarly, it is possible to use application programs (software) via the cloud: ranging from word processing through calculation tables to complex plans for design or image editors. The cloud provider always updates the contracted software.

Simultaneously, various apps are available with which data in the cloud is synchronized between multiple fixed or mobile devices. All those who have the right to access it always have the updated version of a file. Furthermore, numerous people with access rights from a project or company can work with data in the cloud simultaneously.

An essential component of cloud computing is backup. The most secure server farms have redundant memory but are also well protected physically and thermally. Thus, all data is stored in a safe place and is always available to users.

How does a cloud work?

The cloud works like a network in a company where you have to log in from your computer at your workplace in order to have access to the contents of the company server. The cloud server is not located in the company headquarters, but in a server farm, far from the company headquarters. Special routine administrators manage the hard disks, processors, and memories “gathered” in the server. Users have access via interfaces to the infrastructures on which they are registered and / or to the software guaranteed by contract. The user receives an access authorization. The data can be managed as on a hard disk and the programs can usually be used via a web browser.

When companies make their servers for cloud computing available to their employees, it is called a private cloud. In practice, the user accesses the company server. The services and data saved here are not publicly available. Therefore, sensitive company data remains managed internally. In accordance with the GDPR, some data cannot leave the company. A private cloud, however, requires a lot of administrative effort and is a waste of time and costs.

A bcloud makes its services available to the community via the Internet. The managers monitor and maintain the system, adapting it to the user’s needs. Thus within the company the costs for the creation, management and adaptation of a server architecture within the company are reduced.

The combination of these two solutions is called a hybrid cloud, where sensitive data is stored internally in the company and other work files are protected and publicly accessible.

How is the data saved in a cloud?

Files in cloud computing are saved just like on a computer hard drive with reading and write access. The user’s difference is that in addition to the letter for the support of their hard disk, for example, DATA support (D :), there is a cloud support symbol for opening and saving data. In the user account, the cloud offers the same possibilities as your hard drive: creation, deleting folders and subfolders, uploading, saving, updating, moving, renaming, and deleting files of any type. In this manner, it is also possible to securely store complete backups of databases or other mobile devices such as smartphones or tablets.

Even in the cloud, data is saved in an encrypted and redundant manner (i.e., several times). Even transmission to the cloud server and from there to the user takes place via an encrypted and secure data connection. The internal data management between servers and security servers and the creation of regular backups of customer data is the responsibility of the cloud manager. With server locations in Italy or within the EU, cloud service providers are subject to primary EU data protection legislation so that users can rely on the highest security standards.

When is it helpful to use a bcloud hosting?

It is not easy to answer this question. There is no fixed formula that says, “Starting from x gigabytes of data per unit of temp, a company needs a cloud.”. There are various factors to consider for or against using a cloud. The cost and benefit analysis must compare all financial aspects, including maintenance, repair, depreciation, other economic-commercial factors of IT in the company, the costs for using data, and outsourced programs. It should also include a forecast of how the computing capacity will be developed to face future challenges.

When you use cloud services, the costs of renting the storage space also include those in the server’s maintenance and security. The cloud hardware is always up to date, including the latest data and physical security measures. Furthermore, by making licensed software (such as Microsoft Office 365) available through cloud computing, the company no longer needs to purchase individual software licenses and updates.

Most cloud service providers make a portion of the storage space available for free or with hosting agreements. Thus companies can have the first approach before choosing a more extensive paid version.

However, the use of cloud computing assumes a great responsibility for all users who can access it because they must strictly comply with the company’s security standards to protect company secrets from access by outsiders. It is therefore preferable to set up the rights and to keep adequate documentation.
