comparison of types of dedicated servers
To make your choice easier, we have prepared a comparison table of the main properties of three types of dedicated servers. The wording here applies specifically to our implementation of these types of servers. Other providers may have slightly different properties.
| Hardware dedicated server, bare metal hosting | Virtual dedicated server, virtual machine, VDS, KVM | Virtual private server, container, VPS, LXC | |
|---|---|---|---|
| Price level | Medium to high The lower price level is determined by exclusively allocated hardware |
Low to high Using the cheapest packages can be difficult without some special system configuration |
Low to high Even the cheapest packages can be used effectively as long as the load is not very high |
| Price performance | Normal Meets the parameters of equipment that is completely under your control |
Better The gain is achieved through more perfect utilization of equipment |
Best There is no overhead on the operating system kernel, also optimized use of buffers and caches |
| Versatility | Highest Any operating system and software for x86_64 architecture can run |
High Most x86_64 operating systems are supported but require appropriate drivers for optimal performance |
Moderate Linux only. A choice of dozens of popular distributions and hundreds of pre-installed software templates are available |
| Flexibility | Low To replace server components, we agree with you on the work time a couple of days in advance. Typically, replacing components requires approximately 20 minutes of server downtime. Hot swapping is only possible for HDD and some SSD |
High Changing the processor performance and memory size only requires a server reboot. Changing the disk capacity is also possible but requires additional actions on your part |
Very high Changing processor performance, memory size and disk capacity is possible on-the-fly without downtime or server reboot |
| Data privacy | Highest Data privacy is determined only by your setup. You are free to implement any security measures on the server, including disk encryption. If you work with sensitive data, we recommend only this service |
Moderate to high Your server's disk image is stored in a storage facility that is under our responsibility. You can enhance data privacy by using disk encryption. |
Moderate All your server files are stored in a storage facility under our responsibility. We take all possible measures to protect them, but we do not recommend using this service for working with sensitive data |
| Data reliability | Depends on hardware All data is stored on physical server components, which may fail from time to time. You are fully responsible for the safety of your data. Most of our servers come with paired disk sets. You can set up a mirrored RAID-1 on them. |
High Virtual servers operate on redundant storage, most failures and component replacements of which are transparent to you. In the event of a completely catastrophic situation, data will be restored from backups with a delay of approximately one day. However, please note that neither we nor any other provider, regardless of their promises, can guarantee 100% data safety. We provide 99.9%, the remaining 0.1% is on you |
High Basically the same as with VDS. In case of a disaster and recovery from backups, the file system will be restored to a consistent state without the need for a check and repair. The state of the databases, however, may require it. The golden rule that we provide 99.9% and you 0.1% remains |
