** What is a cloud server? What services do you have? Why are traditional enterprises choosing cloud servers? What are its advantages?
** Traditional servers are self-built. ** You have to draw the drawings and give them to the builder to build your house. You have to worry about land, utilities, renovations, etc., etc. The house is built well, live uncomfortable, or silently bear, or wu wu your small heart: ouch I go, transformation expansion and money ah!
** Public cloud server, is a group rental, ** of course also have local rich: this building I rent. You basically don't have to do anything. The landlord builds the house, the fittings are all set up, and you just have to move in with your luggage and pay rent. Although it's a few rooms, the building is built to villa standards, luxury property, careful security. I don't like living here. Shit, move! The new landlord happily ran over to help you take the luggage, the old landlord cried and hugged your leg: elder brother, don't go!
Developers south to build a lot of residential areas, you rent a bedroom, this is called cloud server rent;
You see a model apartment, tell the landlord, according to this standard give me a few rooms, I want to rent. This is called a public image creation cloud server.
You rent a room, rearrange it, and then take a picture of the room, and say to the landlord, you press this to give me a few of the same, I want to rent, this is called private image to create cloud server.
If you feel uncomfortable living in a flat with only one room, you have to pay the whole rent to feel good. This is called bare metal service.
You have your own company and want to solve all the housing problems for your employees. You find the landlord to rent several buildings, which is called exclusive host.
After two days mother-in-law a family of more than ten people to play, you rent a few, and so on mother-in-law play over and go, you return the rent of these several, this is called cloud server elastic expansion;
After you decorate the house satisfactorily, you take a picture. You have a party and make a mess of the house, and you are too lazy to clean up. You give the picture to the landlord and ask the landlord to restore you according to the picture.
When you open the door after the party and see your friend off, you find that the floor of your room has changed! I go to! Through! This is called cloud server live migration. (Friendly reminder, actual situation: customers are not aware of the specific physical location of the cloud server)
The above through popular language, the cloud server related products and services for everyone to bring knowledge popularization. As we all know, now the cloud is the trend, not only IT Internet companies widely use cloud servers, some traditional enterprises also began to choose cloud servers in the process of information. As mentioned in the beginning, physical servers have many problems in the upgrading or transformation of enterprise IT infrastructure. Cloud servers have many advantages over traditional physical servers, which are mainly reflected in the following aspects:
1, low cost
In the past, enterprises had to purchase various hardware, including physical servers, to deploy traditional IT infrastructure, which was a fixed cost. The subsequent maintenance and technical iteration of the equipment, and the purchase of equipment to be updated, is an uncertain additional cost. These fixed and uncertain costs contribute to the high total cost of traditional IT infrastructure.
The development of profit-driven technology, in order to reduce the cost of enterprise IT, the development of cloud server technology is a good choice. Cloud server is located in a huge cloud computing resource pool established by cloud service providers. Cloud service providers use the scale effect of cloud server to reduce the cost of cloud server. Enterprises only need to access the network to quickly purchase the low-cost cloud server, and enterprises do not have to bear the cost of hardware equipment procurement and operation and maintenance, and reduce the cost of manpower and material resources, because after using the cloud server, cloud service providers do all these things, enterprises do not have to consider these problems.
2, performance advantages
In terms of overall performance, traditional physical servers cannot compare with cloud servers. Cloud computing makes use of virtualization technology. Cloud servers have the advantage of elastic computing and can obtain more powerful computing capacity, while enterprises can freely and seamlessly deploy their services to the cloud.
Traditional physical servers have great limitations and are difficult to expand their computing capabilities. Cloud service providers can constantly take advantage of the latest technology and update hardware equipment, which is difficult for enterprises alone, especially start-ups. So compared to cost and performance, cloud servers are very cost-effective.
3. Ensure the continuity of business
The rapidly changing market environment makes the business always facing changes. When an enterprise needs to migrate service data, IT is very difficult to migrate service data from a physical server in one place to a physical server in another place, which involves various aspects of enterprise IT. Improper migration may cause service interruption and customer data loss.
If the powerful network transmission capability of cloud servers is used, service data can be freely migrated between regions and even extended to global regions, with high security and convenience, thus ensuring service continuity.
4. Flexibility and flexibility
When the service volume of an enterprise bursts out in a short period of time, the required IT resources must be expanded in a timely manner. IT is slow and difficult to replace physical servers and upgrade hardware configurations. When the service volume decreases, IT resources that are expanded during an outbreak are empty and wasted.
Cloud servers are flexible and can flexibly configure CPUS, memory, and bandwidth to cope with rapid changes in service volumes and avoid waste of IT resources.
5, no high level of operation and maintenance technical ability
The traditional IT architecture of an enterprise has a large number of hardware devices, requiring a large number of technical personnel to operate and maintain, and to deal with network security threats, which requires an operation and maintenance team with a high level of professional skills. Even so, sometimes operations teams can be overwhelmed by unexpected cyber attacks.
Cloud service providers not only have more professional and higher level of operation and maintenance technical capabilities, but also have stronger network security capabilities. Enterprises using cloud servers do not need to worry about technical and security capabilities, and do not need to build a large high-level operation and maintenance team, thus saving labor costs.
