Dedicated Server Hosting Advantages And Its Types
The dedicated hosting server is exclusively used by a single user for online project. Their advantages and disadvantages are almost opposite to those discussed on shared hosting:
Advantages :
- They are the stewards of the machine. They can connect via the Internet just as if we had it in our office: We may install applications and move windows, change the settings.
- Increased security because no one else uses the server.
- There is no limitation on the resources that we can use except those imposed by the hardware of our choice.
Disadvantages :
- It costs more than shared hosting, but if the data transfer will be very high because of large number of visits, could go even cheaper than paying the extra money for the use of resources on shared hosting.
- The server could be managed by us. This can become a problem if we want the power of a dedicated server but do not have sufficient knowledge of administration. It may therefore be important to hire a service provider who inspire us confidence and management service that provides server at extra cost. That way if we have a problem we know we cannot always resolve the problems.
Types of dedicated servers
The dedicated servers are differentiated by the hardware they include. When choosing a server, the three main criteria that must address are:
- Brand Computer or Clone
- IDE or SCSI hard disk. Possibility of mirrored hard drives with RAID
- Amount of RAM, amount of hard disk space and one or two processors
Let us see in detail each of these three criteria.
Branded computers against clonic
A clone computer can be a good choice for work or desktop computer for its price / quality ratio, but an Internet server is very different. An Internet server is used for hosting (web hosting, databases, email, etc.) is a team that is under strong activity and have to endure:
- Staying connected 24 hours a day throughout the year.
- Peaks of activity depending on the time of day.
- Strong disk accesses if you have applications with databases.
- CPU intensive if you have a mail server or dynamic web applications.
But mostly, a web server must have a reliable team, a team that:
- It has passed a thorough quality control in order to prevent the escape of defectives whose problems can manifest being in production
- Do not hang unexplained because drivers are not released enough or because its hardware is not fully compatible
- It is 100% compatible with most popular operating systems for servers: Windows and Linux.
Therefore, and in order to avoid further problems, we strongly recommend choosing branded Dedicated Servers rather than clones. Your monthly cost is slightly higher but less than it may seem at first glance.
Keep in mind that in the monthly cost of a dedicated server is influenced by many factors that are the same regardless of the server model: The power consumption, data transfer, occupation of space in the data center that is housed , etc.
Therefore, even assuming that the branded machine is far more expensive and its impact on monthly cost which would not be so high as it might seem at first sight
IDE or SCSI hard disk. Mirrored hard drives with RAID
IDE hard drives are standard for desktop computers. SCSI hard disks are controlled by a special chip, which means that when disk accesses are performed, the CPU does not have to work.
The result is that computers with SCSI have a much higher performance disk accesses without overloading the CPU of the machine
Internet servers are often characterized by a large number of accesses, proportional to the number of visits to the website have simultaneous disk. Therefore it is recommended to choose a Dedicated Server with SCSI. The SCSI is interesting improved hardware for an Internet server.
RAID is a hardware-based system that allows synchronization of two hard drives. The operating system sees only one disk, however RAID internally maintains synchronized data. If one of them were ruined, the server still work with the other, throwing both a warning to the server administrator.
RAID is a hardware improvement recommended for critical applications where it is imporant to ensure that they are always running
Amount of RAM, hard drive and one or two processors
The three hardware resources are quantitative RAM, hard disk space and the possibility of including a second processor in the machine.
Normally servers come with a standard size of RAM and hard disk, making it possible to choose both extras and a second processor. The desirability of increasing these resources depends on the use to which it will give to the server, ie, applications that run on it.
In general, it is desirable to increase the RAM for complex web applications, especially if they are developed in Java.
The hard disk space may be necessary to increase if you have databases that can grow a lot or a mail server with many users as mailboxes tend to consume disk space increased due to the accompanying messages.
Regarding the second processor, it is very useful in applications where the limit is given by the processing power, such as databases or mail.
