What is VPS virtual server?

What is a physical server?
A physical server (Server) is a computer that is connected to a computer network or the Internet. Unlike a normal computer, the server is installed with outstanding features to have high processing capacity. The server has a large storage space and is installed with software to serve other computers to access to request services and resources. Servers are considered the foundation of all services on the Internet. Any service on the Internet such as websites, applications, games, etc., to operate, must also go through a certain server.
Cloud Server
Cloud server (Cloud Server): is a server that combines many different physical servers with a SAN storage system. With outstanding access speed, the cloud server is fast, stable, and has low downtime compared to the physical server. The cloud server is built on the basis of cloud computing technology, so it is easy to upgrade each piece of equipment during use without interrupting the use of the server.
Compare virtual server VPS infrastructure with physical servers and Cloud Server
| STT | Criteria | VPS virtual server | Physical server | Cloud Server |
| first | How it works | Initialized and running on a physical server. | Works as a standalone server. | Store and operate on the cloud computing infrastructure system. |
| 2 | Stability and Availability | – When the physical server fails, it can cause data loss and the system will be affected and stop working. – During peak hours, the physical server may be suspended resulting in VPS downtime. | – When the physical server fails, the entire system will be down. – A damaged hard drive will cause data loss and is unlikely to be recovered. | – Cloud computing technology helps the system to operate stably, uptime ability 99.99%. – All components are set up for backup and automatically replaced when damaged, ensuring the system operates 24/7 with safety and high availability. |
| 3 | Ability of extension | - Complex upgrade. When upgrading, you need to buy specialized hardware equipment – The downtime when upgrading is quite long. | – Cannot scale large resources because the physical server that makes up the VPS is not responsive enough. – The expansion time is quite long to upgrade and expand for the physical server. | – Can expand or shrink immediately when the business needs. - Unlimited resource scalability. |
| 4 | Cost | – Pay for the purchased VPS configuration, even though the demand changes afterwards, it can be much lower than the amount purchased. | – The physical server costs a lot of investment for the entire hardware. – System operation and maintenance costs are also very significant – High cost of backup implementation. | – Pay only for actual needs (CPU, RAM, HDD... configured as required) - Costs can be flexibly changed according to the requirements of the business. |
