In the article about the types of servers, we found out that basically servers differ in technical design and are usually divided into rack, disk and tower. These are physical servers that fill data centers, they are located in special rooms of large companies, as well as those who need additional independent computing resources.
What are the pros and cons of a physical server in the form of an autonomous ”hardware”?
First of all, it is worth noting that any type of server is selected for individual requirements, depending on the tasks – there is a solution, otherwise you can lose money and not get significant advantages to overpay or get an extra "expense item" with unreasonably high costs. It is also worth remembering that in addition to the classic offers, there is always an opportunity to choose non-standard configurations for the specific needs of the customer. It is better not to rush, and always consult with specialists.
So, a server in the form of a physical “machine” or “hardware” has the following advantages:
- Complete independence and confidentiality of data. No one except the owner or the company's specialists will be able to disable the server or access it.
- Solve problems on the spot. If there are any difficulties with the operation-you can fix the situation without leaving the server. A manual restart or other required action is performed without contacting the support service or using remote access, as is the case with a dedicated and virtual server.
- Optimal power capacity. After calculating the necessary costs, you can disable the extra servers or take them in other work.
- Maximum protection against hacking or unauthorized access. In an emergency, you can simply disconnect the server from the network.
- Individual communication architecture between computers and office or production equipment. It is always possible to rebuild local networks without unnecessary hassle.
- Using your own software or developments that you don't want to "shine" anywhere else.
- Quickly isolate point problems. If there is a problem with one server section, you can reallocate power while it is under repair.
- Despite the significant advantage in the form of full autonomy of work and full ownership of physical media, such servers have a number of significant disadvantages. Among them are:
- Requires a separate room with a special climate. In order for the server to be fault-tolerant, the hardware must be maintained in an optimal state – the temperature and humidity of the room must be within the permissible limits.
- Maintenance costs. The server requires separate technical support. First of all, it is an uninterruptible power supply line, a ventilation and cooling system.
- The work of specialists. The servers are configured and maintained by system administrators and programmers. They also quickly fix problems or re-equip equipment and network communications.
- Increase in the item of expenditure. Purchase, setup, maintenance, additional staff-all this increases the material and financial costs.
- Some exceptions are tower servers, which you can configure yourself, but you need to be a specialist. Also, they are usually not fully equipped, so that the owner can get the necessary components for their requests. Therefore, such a solution is most often used in IT startups. Support costs are lower here, but still require additional investment.
For whom does it make sense to buy servers of this class? The decision in favor of a set in the form of physical "machines" is made if you definitely need:
- Full autonomy of the equipment operation.
- Data privacy.
- Local network independence.
- Large capacity with the ability to redistribute quickly.
- Manual access to server management.
- Work with unique software.
- Emergency shutdown or quick restart of the server.
To do this, you will need:
- Additional space or room.
- Separate power and climate maintenance line.
- The work of specialists.
- Another part of expenditure.
In summary, we can say that this choice is inclined to large companies, which are safer to rely on their own capacity in the form of tangible equipment, even with additional costs. On the other hand, such a solution is not always required, because there are other options and opportunities for selecting a server for business.
What is the difference between a dedicated server and a virtual and cloud server, we will discuss in the next article.
