云服务器与传统服务器的优缺点对比

云服务器与传统服务器的优缺点到底是什么？其实服务器本身没有“云”的概念，只是因为业界对于“云计算”本来就没有统一的理解，也就没有办法把某一类服务器称之为“云服务器”。设备厂商宣称的“云服务器”，无非就是认为，这类服务器更适合某类（注意，仅仅是某种类型）云计算服务而已。所以如果一定要给适用于云计算服务的服务器总结一个特点的话，那就是“高效率、低成本”。

因为服务器需要内存、硬盘、CPU，才能组成一台服务器。而云服务器把所需的资源都统一放到一个大的资源池，按需提取，按需使用。下面小编给你们总结了四个大点。

1.灵活性

云服务器的硬件配置可以根据需要（不同时期的网络配置）灵活配置与扩展，如CPU、内存、SSD数据盘。而传统服务器的扩容麻烦，部署繁琐。

2.性能方面

云服务环境采用高端服务器进行部署，同时采用集中的管理与监控，确保业务稳定可靠。更强的云主机性能，总体性能远高于vps，强于部分独立服务器。

3.数据安全性

云主机有数据备份功能，就算是硬件出现了问题，数据也不会受到影响或者是出现丢失。只需要后期的正常维护和运维就行了，而且这个是云服务商在维护的。就算是网站运营出现了问题也会自动转移到其的机器上，黑客攻击也会很困难。

4.支出成本

云服务器支持月付、年付，灵活计费方式，无需押金，按需弹性扩容，只需为使用的存储能力、计算能力与资源支付费用，需要多大就买多大，不会造成资源的浪费。而传统服务器租用需要一次性支付很多费用，一般是按半年/年计算。

What are the advantages and disadvantages of cloud server and traditional server? In fact, there is no concept of "cloud" in the server itself, just because there is no unified understanding of "cloud computing" in the industry, there is no way to call a certain type of server "cloud server". The "cloud server" claimed by device manufacturers is nothing more than that it is more suitable for a certain type of (note, only a certain type) cloud computing services. So if we have to sum up the characteristics of the servers that are suitable for cloud computing services, it is "high efficiency and low cost".

Because the server needs memory, hard disk and CPU to form a server. The cloud server puts all the required resources into a large resource pool, extracts them on demand and uses them on demand. Here are four big points for you.

1. flexibility

The hardware configuration of ECS can be flexibly configured and expanded according to the needs (network configuration in different periods), such as CPU, memory, SSD data disk. However, the expansion of traditional servers is troublesome and the deployment is tedious.

2. Performance

The cloud service environment adopts high-end servers for deployment and centralized management and monitoring to ensure stable and reliable business. More powerful virtual machine performance, the overall performance is far higher than VPS, stronger than some independent servers.

3. Data security

Virtual machine has data backup function. Even if there is a problem with the hardware, the data will not be affected or lost. It only needs later normal maintenance and operation and maintenance, and this is maintained by cloud service providers. Even if there is a problem in website operation, it will automatically transfer to its machine, and hacker attack will be very difficult.

4. Expenditure cost

Cloud server supports monthly payment and annual payment, flexible billing method, no deposit, and flexible expansion on demand. It only needs to pay for the storage capacity, computing capacity and resources used, and it can buy as much as it needs, which will not cause waste of resources. However, traditional server leasing needs to pay a lot of fees at one time, which is generally calculated by half a year.
