What is the difference between traditional servers and cloud servers?

What is the difference between traditional servers and Cloud Virtual Machine? Many novices are not very clear about this. In order to help you solve this problem, the following small series will explain it in detail for everyone. Those who have this need can come to learn. I hope you can gain something.

Traditional servers have independent CPU, memory, hard disk, storage data security is not high, the waste rate of hard disk is relatively high, once the enterprise expands the business, the original server resources are insufficient, and it is necessary to purchase a new server, and the physical server also has aging, damage, maintenance and other aspects, resulting in cost and time waste is not underestimated.

Technically speaking,

Cloud Virtual Machine uses cloud computing technology, which integrates various software and hardware technologies such as computing, network and storage, and reasonably integrates, optimizes and applies these resources, thus creating more value. Traditional servers are independent and cannot integrate these resources.

In terms of safety,

Cloud Virtual Machine has natural anti-ARP attack and MAC spoofing, snapshot backup, permanent data loss, to ensure data security. Traditional servers do not have this capability.

In terms of reliability,

Cloud Virtual Machine lease is based on server cluster, so hardware redundancy is high and failure rate is low; while traditional servers have relatively low hardware redundancy and high failure rate.

In terms of flexibility,

Users can add their own configuration online in real time, with a large expandable space and flexible deployment according to business needs; traditional servers have limitations in this regard, and if there is a new application, only one more can be added.

In terms of cost,

Cloud hosts are generally pay-as-you-go, flexible expansion, no need to purchase physical servers, no need to set up computer rooms, no need for regular maintenance, maintenance, etc., not only can save infrastructure costs. It also saves costs for IT operations.
