Difference between cloud server and traditional server!
Let’s start with a more graphic analogy to illustrate the difference between the two.
Renting a server is the traditional equivalent of renting a three-bedroom house for yourself; sharing a server means that everyone shares the house (one room per person, living room and other facilities); and web hosting is the equivalent of putting many single beds in a three-bedroom house, and you can only rent one of those beds.
The metaphor above is very easy to understand, in this environment it is difficult to avoid interference or intervention by others, even later VPS is not a move to change the story, however, the emergence of cloud servers completely changed the disadvantages of this shared lease.
The cloud server is no longer an N-room house that everyone can rent or share independently, but like a hotel that sets up different standard rooms, with all facilities independent in each house, there are different room sizes that everyone can choose, you can even rent a small standard room with independent facilities at a slightly higher price than the virtual host. To sum up the advantages of a cloud server in one sentence: It is possible to expand the facilities rented by the host exclusively and flexibly (you can always settle for a larger room if you have money).
Cloud computing server (also known as cloud server or cloud host), is a host product in the cloud computing service system, the product effectively solves the traditional physical host and VPS services, the existence of management difficulties, business scalability weak shortcomings. The host service configuration and business scale can be configured according to the user’s needs and flexibly adjusted. The hosting service applied by the user allows for rapid deployment and provisioning (real-time online provisioning), flexible and scalable billing within the cluster, with no deposit required, and a variety of payment options available to users.
Differences between cloud servers and traditional servers
1. From a security perspective: Cloud servers have natural anti-ARP attacks and MAC spoofing, snapshot backup, data is not permanently lost. Standalone servers do not have this feature;
2. From a technical point of view: cloud servers use cloud computing technology, which integrates various software and hardware technologies such as computing, networking, storage, etc. Stand-alone servers, that is, they are independent and do not integrate these resources.
3. From a reliability point of view: Cloud servers are based on server clusters, so hardware redundancy is high and the failure rate is low; whereas with standalone servers, hardware redundancy is relatively low and the failure rate is high.
4. In terms of performance: the cloud server is 4 times more powerful than the standalone server with the same configuration, which can meet the requirements of high-performance computing.
5. From the point of view of energy saving, the cloud server is based on the automatic migration technology of cloud computing, i.e. at night the utilization rate of physical servers is not high, the automatic migration technology concentrates the application on a few physical servers, other physical servers can be dormant, which means energy saving.
6. In terms of flexibility: users can add their own configurations online in real-time, can expand the space; while stand-alone servers have limitations in this respect, if there are new applications, they can only buy another one.
7. In terms of stability: cloud servers can fail the automatic migration, i.e. if one cloud server fails, the applications on it are automatically migrated to other cloud servers. The standalone server no longer has this function, it has failed.
