What is cloud server ？ What are the advantages of cloud server ？ What can be used for ？

Many people don't understand the definition and purpose of cloud server .

ECS is simple and efficient 、 Computing services with scalable processing power , Help users quickly build more stable 、 Secure applications , Improve operation and maintenance efficiency , Reduce IT cost , Make users more focused on core business innovation .

Different manufacturers have different abbreviations for cloud servers , Alibaba cloud calls it ECS, Tencent cloud calls it CVM, It's called Baidu BCC.

Compared with traditional servers , The advantages of cloud server are mainly reflected in its flexible capacity expansion , More stable 、 Cost savings , And the safety factor is higher .

One 、 stability

Cloud server ： The instance availability reaches 99.95%, Cloud disk data reliability is not lower than 99.9999999% ; And automatic downtime migration , Automatic snapshot backup （ You need to manually configure the snapshot policy ）, Data recovery is more convenient ; Traditional servers ： Limited by hardware reliability , Go wrong ; And it needs to be backed up manually , Manual data recovery is difficult 、 Time consuming .

Two 、 elastic

Cloud server ： It can be configured freely CPU、 Memory 、 bandwidth , Upgrade at any time ; Upgrade configuration data is not lost , Business suspension time can be controlled ; Traditional servers ： Fixed configuration , It's hard to meet all kinds of needs ; Hardware upgrade is needed to change the configuration , Cycle is long , The service stop time is uncontrollable .

3、 ... and 、 Security

Cloud server ： Free supply DDoS protective 、 Trojan horse killing 、 Services such as the prevention of violent invasion ; It can easily realize the access control of multi-user to multi server ; Traditional servers ： Additional purchase required 、 Deploy various security measures ; Basically can't do multi-user to multi server access control .

Four 、 cost

Cloud server ： High cost performance , Support monthly package or pay as you go , Meet different needs ; No need for server network and hardware maintenance ,0 Cost operation and maintenance . Traditional servers ： The cost of renting is high , You can only buy it on a monthly basis ; A large number of people are responsible for the operation and maintenance of the machine , The high cost .

5、 ... and 、 Usability

Cloud server ： Rich operating system and application software , The image can be deployed with one click ; The same image can be used in multiple stations ECS Fast replication environment , Easily expand ; Traditional servers ： Almost no software support is provided, and all deployment operations need to be manually repeated for new servers

6、 ... and 、 Expansibility

Cloud server ： A variety of rich cloud products connect seamlessly ; Sustainability provides complete calculation for business development 、 Storage 、 Security and other solutions ; Traditional servers ： It's hard to find a complete service within the same service provider ; Can't support the scalability and sustainability of business growth .

It is often said that cloud computing services will be like public facilities such as tap water in the future , It's simpler , More powerful . Now it's obviously moving in this direction , Whether it is a technical professional team or passionate individual webmaster , Make good use of cloud servers , Can greatly save their own time and economic costs .

1、 data storage , Data backup can be realized 、 Data recovery, etc

2、 Make a website , Complete e-commerce and other functions , cost reduction

3、 Use various cloud products , Image deployment of various websites , Realize various functions .

Compared with traditional servers , The advantages of cloud server are mainly reflected in its flexible capacity expansion , More stable 、 Cost savings , And the safety factor is higher .
