1. cost. Let me give you a simple example. I have a client who is a local clothing wholesaler. Their company is responsible for the design and sales of clothing, and the production is handed over to other factories for OEM. In Yunnan province, almost all parts of the province, the use of franchise stores. At present, there are more than 120 franchise stores in the province, all of which use computer cashier to put them in storage, and all information needs to be fed back to the server of its head office. At that time, their boss came to me and asked me to design the server configuration according to the number of 200 points in the future and run an ERP management software. The system required WINDOWS.
After I communicated with the technicians of their company, the configuration adopted at that time was: i7-4770 processor, 32GB memory, Z97 motherboard 128GB+2000GBX2, graphics card GT7302G discrete graphics card, common tower server, Great Wall Gold Medal rated 500 watts power supply, and the system was installed with SERVER2008. Counting the whole server, I remember it was more than 7000 yuan for him at that time. Which boss bought two identical ones, and one of them was equipped with a monitor. Many people may laugh, why do you configure the desktop instead of the server? But it's true. Although it seems that there are more than 120 stores in this client, there are actually about 40-50 IP links. Even if his stores expand to 200 in the future, there is no problem, which is completely sufficient in terms of performance.
At the same time the price is also the most affordable. The purpose of buying two sets is because one server in their company is the main server and the other server is a hot backup. Technicians will use it to play LOL and watch movies. . I turned on IP automatic switching for two of them. One of them had a problem and the other took over automatically. It's that simple. In addition, the 50-meter upload speed optical fiber connected by their boss and the UPS configured by each server can actually cover the investment of 20,000 yuan in the first year, and then the optical fiber fee and electricity fee will be more than several thousand yuan a year, which is the cost advantage. Otherwise, their company keeps technicians and uses them to install the system?
2. Safety. By security, I mean the security of data. The servers in their company are RAID 1 array, and two servers are used for backup. The possibility of data corruption due to hardware is very low. The most important thing is that the information inside their company doesn't want to be known by anyone in other companies, especially the contact information of customers, sales performance of customers, etc. These are trade secrets. You said cloud server, why should I believe that Alibaba Cloud must have professional ethics? To put it bluntly, Alibaba Cloud or a cloud secretly sold the information to you. Do you have any proof? Does your company have time to file a lawsuit with a giant company like them? Therefore, in terms of security and cost, large and medium-sized enterprises do their own servers and rarely engage in cloud servers.
Not to mention which client server configuration I just had, please try it according to the price in Alibaba Cloud and see how much it costs a year. I'm sure you will be very sour after reading it. The most important enterprises at this level have at least hundreds of computers, and all of them have their own technical departments. If they don't have servers, why do they have them? Have they all been fired? I was fired, and then in case the company computer breaks down, I don't have to spend time and money to find someone to fix it.
