Data center third-party services, Financial IT outsourcing services, and social security medical informatization solutions. What are the relationships between these three types of businesses and what are the differences?

This topic is very big and involves a lot of things. It's a nonsense to try to answer it.

The relationships between the three types of businesses are all IT outsourcing, and the outsourcing content is very complicated. DC outsourcing is mostly about infrastructure and maintenance, which is generally not related to software development or website construction. Financial IT outsourcing is much more complicated, and the construction and maintenance of information systems. Software development and website operation. And data analysis. Medical informatization is similar to finance. Three types of outsourcing overlap, that is, IT services. This is actually nonsense... as for the difference, here is a few nonsense words based on my own experience.

DC outsourcing, I am doing system integration. To put it simply, we need to build data centers and perform O & M. As long as the other party provides the IDC infrastructure, we can do anything else. Plan and design the internal equipment from the data center. To power facilities, constant temperature equipment, fire/monitoring equipment. The rest are servers, networks, and messy devices in the IDC. Then there is wiring, device installation, debugging, testing, acceptance, and so on. If the other party does not have a professional person to perform technical maintenance for the IDC room, we can do it and pay for it. This is DC outsourcing and can also be understood as a third-party service.

We do not outsource Financial IT, software or website services. Most of them are background tasks. For example, maintenance for IBM small machines, EMC and HDS storage devices, etc. This requires high technical staff to maintain it, because the data in the financial system cannot be lost. At least two backups are required. What is more complicated is remote backup. The term is disaster tolerance, which was fired after the Wenchuan earthquake in. All major banks, insurance, and securities companies have remote disaster recovery systems. The equipment in the financial system is very advanced, because the money is not bad. It is common for IBM small machines to run critical businesses. Storage, reliable is EMC or even HDS equipment, dead expensive. Generally, IBM and EMC have many outsourced devices, but few HDS devices, which is too expensive. (Ps, some people will say that Dell's storage outsourcing is from EMC to OEMs. Some of IBM's network outsourcing services are the follow-up services of brocade equipment OEMs)

As for medical system, what we do most is the small data center in the hospital. Wiring, Device Access, internal networking, debugging, etc. If some professional medical systems have manufacturers, let's work with them. In fact, this is generally a standard. Hospital bidding, we won the bid according to the rules, you know. Create a small data center. Later, the company had a dedicated person responsible for the hospital. Regular maintenance, dedicated personnel maintenance, and on-call calls. The content is very complex, ranging from the client's reinstallation system to the installation of a printer, to the replacement and upgrade of equipment in the data center.

So much nonsense, except that the data center is relatively simple and does not require much energy. The other two industries are complicated and cumbersome. There are many things and things. In many cases, it is not a technical issue, but a link issue. A lot of things, especially when it comes to other things. Then there is a communication problem. The above only represents my personal views and experiences, and is not necessarily reliable. Just look at it.
