Data compression is the compacting of information by reducing the number of bits which are stored or transmitted. This way, the compressed info will take considerably less disk space than the initial one, so much more content could be stored using the same amount of space. You can find various compression algorithms that work in different ways and with some of them just the redundant bits are removed, so once the data is uncompressed, there is no decrease in quality. Others erase unnecessary bits, but uncompressing the data following that will result in reduced quality compared to the original. Compressing and uncompressing content takes a huge amount of system resources, in particular CPU processing time, therefore each and every hosting platform which employs compression in real time should have sufficient power to support this feature. An example how data can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" what number of consecutive 1s or 0s there should be instead of storing the entire code.

Data Compression in Cloud Web Hosting

The compression algorithm that we work with on the cloud hosting platform where your new cloud web hosting account shall be created is named LZ4 and it's used by the advanced ZFS file system that powers the system. The algorithm is superior to the ones other file systems use as its compression ratio is a lot higher and it processes data a lot faster. The speed is most noticeable when content is being uncompressed since this happens quicker than information can be read from a hard drive. Therefore, LZ4 improves the performance of each site located on a server that uses the algorithm. We use LZ4 in an additional way - its speed and compression ratio allow us to make several daily backups of the full content of all accounts and store them for one month. Not only do these backups take less space, but also their generation doesn't slow the servers down like it often happens with alternative file systems.

Data Compression in Semi-dedicated Servers

If you host your websites in a semi-dedicated server account with our company, you can experience the advantages of LZ4 - the powerful compression algorithm employed by the ZFS file system which is behind our advanced cloud hosting platform. What separates LZ4 from all other algorithms out there is that it has a better compression ratio and it is much faster, in particular when it comes to uncompressing website content. It does that even faster than uncompressed data can be read from a hard disk drive, so your websites will perform better. The higher speed comes at the expense of using a lot of CPU processing time, which is not a problem for our platform as it consists of numerous clusters working together. Besides the superior performance, you will also have multiple daily backup copies at your disposal, so you will be able to recover any deleted content with several clicks. The backup copies are available for a whole month and we can afford to store them because they take significantly less space than ordinary backups.
