What is a server, its types and the services it provides

Do you want to create a local network in your company and control it completely? Are you looking for the difference between on-premises server and cloud server and which one to choose for your company? Do you want to know the types of servers or what is a server and what is beyond that, then here is this mini-research that will help you take many important decisions.

A server is a computer that contains components that have far greater capabilities than a personal computer. These components are called resources such as a gigantic processor, storage in zettabytes and more, gigantic random memory and other computer components.

The server maintains data to be shared across the network, and responds to requests for information from computers connected to it through it, whether it is a local network (LAN) or the so-called intranet, or whether it is external through the World Wide Web.

The server serves multiple computers on the same network by providing them with files, data, printing and other resources, the server is managed by technical specialists, which often requires them to handle problems for the connected computers and provide some information to their users, and is responsible for maintaining the server’s hardware or the connected computers or upgrading the hardware, etc. . The server is located on the networks of many companies, whether small or medium, and certainly large, and some of them contain a small number of computers and others on large numbers of devices such as large and transnational companies. If the company has slow computers and files stored on disks that slow down the work, a network server may be the best solution to avoid these problems, this is other than organization, security and many other things.

Services provided by the company’s local server

After knowing what a server is a question comes up, which is what the server offers to your company? There are many reasons to have a server in a company. including file and network security, increased reliability, centralized data storage, shared resources, complete virus protection and centralized backup.

In addition, the user may set up a server to control access to any device on the network, send and receive email, manage print jobs, host a website, specify domain names through DNS, upload files via FTP and other tasks.

Some servers are committed to a specific task, and the server can be set up based on your different needs and functions, and it can also be set up for private access or shared with other., the server can help you connect and communicate remotely and it can help you perform a complex computational task that’s what we can’t do Easily without it. among the benefits and services of other servers are the following:

File Security

File and network security is one of the most important roles of a file server on a network. protection is done by creating individual accounts,where rights can be assigned to data stored on the network to prevent unauthorized users from accessing material that is not under their responsibility or that they should not know.

For example, sales personnel do not need to access personal records of employees. this information is of interest to the human resources department or the owners of the company.

The server allows you to manage access to files on one system instead of each computer separately. which saves time and effort, in addition, if a user’s computer fails that employee can move to another computer to continue working on the same files.

All employees can store their documents inside their personal folder on the server. this storage has two benefits. the first is that the data stored in the employee’s personal folder can only be viewed by the user himself.

The second is that since all employee data is stored on the network. it will be backed up with the rest of the network data. ensuring that no data is lost due to any computer failure on the network.

alternative energy protection

Servers are designed to run at all times. even in the event of a hardware failure. which is why many servers are equipped with alternative power sources. In the event of a power supply failure scenario the server will shut down automatically resulting in data loss and less employee productivity.

With a secondary power supply running in tandem from the main one a loss of one power source does not affect normal system operations and as a result it goes unnoticed by users.

RAID system and data protection

Unlike a normal desktop computer that often uses a single hard drive or SSD. a server typically uses multiple hard drives and an SSD as well which are RAID-powered to prevent data loss or interruptions in workflow due to storage failures. There are many different types of RAID systems To choose from. the most common are RAID-1 and RAID-5.

Full replacement servers

A complete downfall of the server can occur due to a failure of the motherboard, processor, or even random memory. this may require a large reboot time to replace the faulty components. in the event of a personal computer failure. all what you do is shutdown to fix it. but this cannot happen For the server because if the server goes down. the employees will not be able to work. which is why many replacement servers are equipped with hard disk drives, SSDs and switchable power supplies during operation.

Protection against viruses and spyware

One of the biggest threats to your network is the possibility of viruses, spyware, spam, and Danielle DDoS attacks. so having good up-to-date and antivirus software installed on your systems is a must.

Note that in small companies with 10 employees or less can maintain the systems individually. however, increasing the numbers of employees more than that can become a real problem. in that case, an antivirus package that combines hardware and server protection from Viruses in one solution are required.

Many vendors often offer antivirus suites tailored to meet the needs of small businesses. these packages allow a single network administrator to centrally manage every aspect of the antivirus. thus reducing management and maintenance costs.

Through the server, the administrator can deploy the latest antivirus software to every computer on the network. run network-wide virus scans, debug programs, and update virus definition files. The software is designed to use minimal system resources and runs in the background of the computer. Hidden antivirus devices scan for any problems or viruses.

Many tasks such as virus scans and definition updates. can also easily be automated, giving network manager convenience and security.

central backup

All companies should back up their data regularly, reliably and quickly on a server or external storage for added security. In this case, there will never be a problem about the data stored on any peripheral device. It also happens in a peer-to-peer network or randomly linked network devices.

Any type of media can be used for backup. in addition to a traditional drive. Or even backup CDs and DVDs, as well as NAS storage devices. Your choice of backup media depends on the company’s requirements and capabilities depending on the budget and data retention needs for certain durations.

You should make sure that you have at least a weekly backup. But the daily copy will be the best as losing a working week can be very expensive. remember that in most cases the daily copy should start immediately after the end of the working day.

Some services and other benefits of the server

The server allows you to work remotely as employees can work from virtually anywhere at any time. With access to email, internal websites, network files and even business applications. From any computer connected to the Internet.
A server allows employees to share resources and equipment such as Internet access, printers, fax machines, and other equipment.


server allows you to provide high-speed Internet access over the network.


The server gives you more processing power. It stores large pieces of data. It frees memory and enables individual computers to perform better.


server allows you to set up new computers and add users. Publish new apps more quickly and easily.

The server can help you present a more professional image to your clients. It enables you to run web services, manage websites, and create e-mail newsletters. And exploit the most complex tools and applications.

server enables you to merge your email accounts. With suppliers, for example, such as merging Gmail, Hotmail and Yahoo into one email account hosted by the company. Which improves the company’s image for customers and partners.

The server protects corporate information by providing a reliable security architecture. It includes a built-in firewall and remote access with secure encryption to help prevent unauthorized users from entering your network.

server helps ensure network integrity by keeping computers and servers up-to-date with the latest updates.

The server prevents data loss with automatic data backup, and allows you to easily recover accidentally deleted files and restore previous versions.

server provides one central place to store data. Which means you can better manage business-critical information. It makes it easier for employees to find, access, and share information and schedules.

Do businesses co especially small ones need a network server

The majority of small businesses companies don’t bother setting up a server-based network. instead, They continue to add devices to the network in a peer-to-peer fashion with the old system. This type of legacy network doesn’t offer much in terms of security and resource sharing can be somewhat a problem.

So it is not surprising that owners of such companies often have problems accessing computers. or data loss due to viruses or spyware, or they may encounter other problems on the Internet.

Networked computers in a peer-to-peer manner are sufficient when you have a few users on the network. say four employees, but once you have more users on your network. you will definitely want to consider investing in a network server.

It can be difficult to convince a small business owner to make this type of investment. Unlike large companies, small businesses often do not benefit from an IT department or rely on a complex networking infrastructure. Due to the high price of its establishment in some cases due to the failure to study the feasibility of the upgrade seriously.

But it is overlooked in many studies that network servers do not have to be expensive. Or complex to be able to take advantage. although creating a network is not an easy and expensive task if not carefully studied. The benefits of adding a server to the network far outweigh any payments made.

Server types

There are many types of servers that perform different functions. Many networks contain one or more of these types, such as:

Application servers

What is the application server? Application servers run applications instead of computers running them locally. Application servers often offer resource-developed software that engages a large number of users. Doing so removes the need for each user to have sufficient resources to run applications. It also removes the need to install and maintain software on many devices instead of just one.

File servers

File servers can store and distribute files. So multiple users can share files stored on the server. central file storage provides backup solutions. And smoothly bypassing errors trying to provide security for files on every device in the company.

File server hardware can be designed to maximize read and write speeds on hard disks or SSDs to improve performance. Also, print servers allow management and distribution of jobs, rather than attaching a printer to each computer. A single print server can respond to print requests from many clients.

Some newer, more efficient printers come with a print server built into them. Eliminating the need for an additional computer-based print server. the print server works for it by responding to print requests from the client.

DNS servers

DNS servers are application servers that provide name resolution to linked computers. By converting easily understandable names from words into machine-readable IP addresses. DNS is a widely distributed database of names and other DNS servers. Each of those servers can be used to request an unknown computer name. When a client needs a system address. It sends a DNS request with the name of the requested resource to the DNS server. The DNS server responds with the necessary IP address from its name table.

mail servers

Mail servers are application servers of the most popular types. Email servers rely on what so-called protocols such as SMTP and POP / IMAP that allow secure sending and receiving of mail. an email server through one properly configured device connected to the network at all times give The ability to send and receive messages rather than constantly requiring each client device to run its own email subsystem.

database server

A lot of data is stored in databases. Databases must be accessible to everyone at any time and from anywhere. this requires large areas of storage. That is why database servers are used. which run database applications and respond to numerous requests from clients. Popular database server applications include Oracle, Microsoft SQL, the popular MySql and many other databases.

virtual servers

Virtual servers exist in the form of a specialized program called a hypervisor. Unlike traditional servers that install as an operating system on machines, each hypervisor can run thousands of virtual servers at once. The software presents virtual devices to the server as if they were real physical devices.

The virtual server uses the default method. The program passes all the computations and physical storage to the actual hardware underneath. which are shared among all other virtual servers.

Proxy servers

What is a proxy server? A proxy server acts as an intermediary between the personal machine and essential servers. It is often used to isolate clients or servers for security purposes. as well as for other reasons, including bring closer the main server data and personal computers, where copies of that data are kept in to it. The proxy server takes the request from the client, rather than responding to it and passes the request to a server. The proxy server receives the response from the master server and then responds to the client. Thus, neither the client nor the responding server needs to communicate with each other directly.

Monitoring and Administration Server

There are many types of monitoring servers. Many of them monitor the network and monitor users and what is happening between them and the main server. But others do not request or respond to data on their own in this way. The monitoring server can track all traffic on the network. As well as monitoring requests and responses from clients and servers without interfering with those operations. One of the benefits of the monitoring server is that the network efficiency is tracked all the time.

Server operating systems

After knowing what is a server. an examples of server operating systems come. Like Microsoft Windows Server. This system supports many applications and databases in addition to a hypervisor that specializes in virtual servers. some others examples include Linux and Unix servers. which are other competitors of server operating systems. There are multiple versions and distributions of Linux and Unix including Red Hat, Debian, CentOS, and others. They are open source operating systems. Linux is very popular as a web server using the popular Apache web application server.

cloud servers

what is server

Cloud servers are called virtual servers that are built on a third-party infrastructure on the Internet. There are many cloud server providers such as Google Cloud Platform, Microsoft Azure and IBM Cloud. But the main leader in enterprise cloud computing is Amazon’s AWS platform. Which originally started as a back-up to Amazon’s own servers and networks, but now AWS allows customers to create their own virtual server and adjust the amount of resources the server may use.

The difference between local and cloud servers and which one to choose

Good data allows us to move forward and bad data can kill us. Data integrity, quality and open access has become very easy. so you must make sure that you can make the right decision when it comes to storing data especially scientific ones. Where data must be carefully monitored, managed and protected. As for data storage, it must be taken care of and its integrity. But which is better, local or cloud servers?

Which one to choose, cloud or local servers

The question here is where should you store your data? Is it on the cloud or local servers? What are the pros and cons of both?

Today there is a huge increase in data generation at the digital level. That is why this data must be stored securely and securely and that is why there are two options, either cloud or local servers. The cloud is a type of remote server in the form of data centers. Which means you can access it online. Where server space can be rented, rather than owning the server.

A local server is a server that you buy and physically own. One of the advantages of the cloud is that you use many tools based on it including email providers like Gmail, Outlook, and others. Storage and backup programs such as Google Drive, DropBox, and others. and all social media platforms that you may have an account with.

A plus of the cloud is the maintenance, updates, and tuning of remote data storage space. Which can be accessed from anywhere on the Internet, this means that you have almost nothing to worry about. It is also easy to increase or decrease the amount of space on the cloud. For this you only pay a specific amount for what you need.

The data is stored remotely and is not stored on your computer. Which means it doesn’t take up space unnecessarily. If there are technical problems with the site. Your data will be safe on the cloud.

The downside is that the data cannot be accessed without the Internet. However, with some software you can access the data offline, but you will not be able to edit the data without an internet connection. But it can be edited and later synced automatically when the connection is available.

As for the characteristics of the local server, rather than storing the data on the personal computer. You are moving it to another storage device. So that you can access it from any other computers. The pros include download speed, speed of system setup, and security. Where speed refers to the ability to upload or download data to and from the server.

You also have complete control over the system setup. To make sure it fits your needs perfectly. Control also extends to backups. And everything else is about data, since you own the entire server. You may also feel more secure having a local server. Where only you and your team can access it physically and of course digitally.

The downside is that the hardware is expensive to install and will require maintenance. Also, if problems arise you will need to do troubleshooting. Here comes the role of the IT team to save the situation.

You have the option of using a cloud or locally installed server. For both, the communication between your device and the cloud or with the local server is encrypted. Nightly backups of your data are made. This excess storage and backup helps ensure the security of your data. Both update and are subject to extraordinary encryption and security.

But all this is done only if professionals are dealt with to create the local server. Or by dealing with a major company in the cloud field.

What is cloud computing and how is it different from traditional

Cloud computing is the new frontier of computing through the use of remote software and applications. Cloud computing is in rapid progress from working through your PC or traditional computing. It is a reliable, scalable and cost-effective technology solution.

However, many companies that have built their own powerful data centers and traditional IT infrastructures still rely heavily on the traditional model for security and management reasons.

Every business needs a secure storage space. Data and applications can be easily accessed while operating costs are kept to a minimum. If you are considering migrating your data from traditional computing to cloud based systems. You should better understand the benefits of this step.

What is the traditional IT infrastructure? Traditional data centers consist of different pieces of hardware, such as a desktop computer, that connect to a network via a server. This server is usually installed locally and provides all employees who use the devices access to the company’s stored data and applications.

Hardware is procured and upgraded if necessary in order to expand data storage and services to support more users, with software upgrades imposed also ensuring that safe systems are in place in the event of a hardware failure.

For many companies that have IT data centers, an in-house IT department is required for hardware installation and maintenance, on the other hand, traditional IT infrastructure is one of the most secure data hosting solutions, and allows you to maintain complete control of your company’s applications and data on the local server, it’s an ideal dedicated platform for organizations that need to run many different types of applications.

Cloud computing versus traditional IT infrastructure is more effective as a virtual hosting solution. Instead of accessing it via physical hardware, all servers, software, and networks are hosted on the cloud. It is a real-time virtual environment hosted between several different servers and in same time.

So instead of investing money in buying physical servers in-house, you can rent data storage space from cloud computing providers on a pay-per-use basis, which is more cost-effective. The main differences between cloud hosting and traditional hosting is flexibility and hosted information and applications are distributed over Cloud evenly across all connected servers.

Therefore, if a single server fails, no data is lost, and the cloud also provides more storage space and server resources, including better computing power. This means that your programs and applications will run faster.

Traditional IT systems are not very flexible, and cannot guarantee a high level of server performance, they have limited capacity and are prone to downtime at any time, which can greatly hamper productivity in the workplace. Cloud hosting also provides flexibility and scalability. Better compared to traditional data centers.

Cloud computing virtual space has unlimited storage and more server resources, cloud servers can scale up or down depending on the level of traffic your website receives, and you will have complete control to install any software whenever you need it.

This provides more flexibility for the growth of your business. As for using the traditional IT infrastructure, you can only use the resources available to you. If you run out of storage space, the only solution is to buy or rent another server. If you hire more employees, you will need to pay for Additional software licenses are manually downloaded to your office devices.

This can be a costly project, especially if your business is growing very quickly, and automation is one of the main differences between cloud computing and traditional IT infrastructure in how it is managed. Cloud hosting is managed by a storage provider who takes care of all the necessary devices, ensuring that there is Security measures, keeps it running smoothly.

Traditional data centers require extensive internal management, which can be costly and time-consuming for your business, and fully trained IT personnel may be required to ensure periodic monitoring, server maintenance, and many other work such as upgrades, troubleshooting, threat protection, periodic software installation, etc.

Operating costs Cloud computing is more cost-effective than traditional IT infrastructure because of the payment methods for data storage services, and with cloud-based services, you pay only for what is used, moreover, lower downtime means better place performance business and increase profits in the long run.

With traditional IT infrastructure, you will need to purchase additional equipment and server space up front to adapt to business growth, if this slows, you will end up paying for the resources you are not using, and the value of physical servers is declining on an annual basis, so the return on investment Funds in the traditional IT infrastructure is very low.

Cloud computing security is data storage and software delivery, which makes it seem less secure than traditional data hosting, where anyone with access to a server can view and use data and applications stored in the cloud, wherever an Internet connection is available Ensure optimal security measures are in place when moving to the cloud.

One of the benefits of cloud computing is that it provides your business with many things, as it allows you to set up what is essentially a virtual office to give you the flexibility to connect to your business anywhere and at any time.

With the increasing number of web-enabled devices used in today’s business environment such as smartphones and tablets, accessing your data has become easier, and there are many benefits to moving your business to the cloud including collaboration efficiency Whereas collaboration in a cloud environment gives your business the ability to communicate and share more easily outside of methods traditional.

If you are working on a project across different locations, you can use cloud computing to give employees, contractors and third parties access to the same files, you can also choose a cloud computing model that makes it easier for you to share your records with your consultants, and also offers you a fast and secure way to share accounting records with your accountant or consultant financial.

Cloud computing allows employees to be more flexible in their work practices, for example, you have the ability to access data from home, while on vacation, or on the go to and from work, if you need to access your data while you are away from the site, you can connect to your virtual office quickly and easily.

Access to automatic updates is one of the most important factors and this is what your cloud computing service provider offers. Your system is regularly updated with the latest technology, including updated versions of software, as well as upgrades to servers and computer processing power.

In the end, after reviewing what a server is of all kinds and services, you can choose what suits your company, but after a careful feasibility study, which can save you large sums and you can reap many benefits from it.
