What is The Difference Between Cloud and Server?

With the vigorous development of emerging technologies such as cloud computing and the Internet of Things, more and more companies and institutions have begun to gradually shift their IT business to cloud servers. But at this time, someone asked, what are the differences between cloud servers and traditional servers?

1. Virtualization
Cloud server is to build a cloud resource pool through intensification and virtualization of the underlying server of the scale, and then allocate computing resources from the resource pool. Ordinary servers, you can also use virtualization technology to segment a large number of virtual dedicated servers, that is, the VPS we used before.

2, distributed storage
The difference between cloud servers and ordinary servers lies in the difference in storage methods. The cloud server adopts distributed storage, which can realize real-time multi-copy disaster recovery, no single point of failure, can effectively avoid multiple failures, and supports the elastic expansion of storage resources, and enables the cloud server to have functions such as hot migration. Ordinary servers cannot realize distributed storage. Once a hardware failure occurs, data security will face serious risks of loss, damage, or even failure to retrieve.

3. Flexible resource allocation
A true cloud server supports the elastic deployment of resources, which means freely increasing or reducing resources such as CPU, memory, disk, and bandwidth. Such a cloud server makes it really convenient for us to realize the free combination of resources in the way we need to adapt to the increasingly diversified enterprise application requirements. This is also one of the differences between cloud servers and ordinary servers.

4, node scale
In the final analysis, the computing resources of the cloud server are obtained from a large number of integrated virtualized physical servers. From the perspective of the node scale, such a virtualized scale may be a few, tens, hundreds of physical servers, or Thousands of physical hardware across the data center build a large cloud virtual resource pool, while the node scale of ordinary servers is limited by the hardware environment such as cabinets and computer rooms and the degree of virtualization.

In addition, compared with traditional servers, cloud servers are more open. Especially under the trend of big data and artificial intelligence, the processing of massive data still needs to rely on cloud computing to complete. Therefore, under the background of this era, the traditional IT model is still adopted, which may cause a waste of investment.
