1. Physical server (Dedicated Server)
A server running on hardware such as RAM, HDD, CPU, Network Card, etc.
It all depends on the hardware, when it's damaged or changes in server configuration and upgrades, it is necessary to change the server's hardware.
2. Virtual Server (VPS – Virtual Private Server)
VPS virtual server, divided into many other servers from the physical server. And it has the same features as the original physical server. Easy upgrade via system management software
3. Cloud Server (Cloud Server)
As a server built on a cloud computing platform, it is easy to upgrade each part without interrupting the use process.
And it is combined from many different physical servers with the same SAN (Storage Area Network) storage system with outstanding access speed to help the server operate stably.

Notes to pay attention to when using server rental service
When using a server rental service, you need to pay attention to the bandwidth of the internet connection
The speed of using the Internet will be one of the factors that determine a computer's ability to exchange data. Therefore, you need to pay attention to the real speed of the Internet, especially the speed when shared with another host. You can find out information about the server's bandwidth on Google or ask for details about service providers.
2. Need to pay attention to the capacity and speed when renting a Server
