Server is a general name given to computer units that run some services (FTP, E-Mail, Website) or open resources that clients (users) can access, use and share in computer networks. If the server computer broadcasts a Website according to the service it offers, it is called Web Server, If it broadcasts mail services, it is called E-Mail Server or Database server.
The server, also called the server, is the heart of the internet. Website owners are required to rent a space on servers for their site to be published on the internet. In addition, servers; They can also be used in such a way that the software needed by individuals or institutions can be installed with the rental process called server rental.
Where is server hosted?
The servers are located in centers called data centers, where there is a very high speed internet connection and high-level security measures. Depending on the size of this center, hundreds or tens of thousands of servers can run at the same time. While small-scale hosting companies serve with only a few web servers; Companies around the world have hundreds of thousands of servers spread over almost every country.
Physical Server
Some servers are used only for defined tasks. For example, a program server just hosts the website. In other words, network users can run the corresponding computer program without downloading the copy data to their computers. Physical servers called dedicated servers can easily host the site. Since it is especially important for companies, the physical server type should be installed with high-tech, special equipment components.
Physical servers can easily perform many operations on the network they are used, thanks to their software and hardware capacity. Some of those transactions are:
> OS updates
> SNMP hardware monitoring,
> Firewall services,
> Anti-spam software
> Antivirus updates
> DDoS protection
> DNS hosting service
> Disaster recovery
> Intrusion detection
> Database management
> Backup and restores
> Security controls
VPS Server
VPS server, which stands for "virtual private server", shows you completely special server features. Usually, a physical server is divided into virtual server parts by virtualization software. Thus, completely independent servers run on a single physical server. Here is one of the servers rented by the website owners.
Since components such as processor and memory belonging to physical servers are clearly shared among website owners, the slowdown experienced in other VPSs will never affect the sites in your VPS. Likewise, it is not possible for other VPS to use the resources reserved for you.
CloudServer
Cloud server, also called cloud server, cloud hosting or cloud VPS terms, is actually almost similar to VPS. The only difference is that while VPS is a single physical server split into virtual parts; A cloud server is formed by the separation of a network of many physical servers into servers.
Other Server Types

FTP server: FTP servers are systems that allow files to be transferred with "File Transfer Protocol" tools. In other words, remote access to file transfer servers can be achieved through FTP client programs.
