Data compression is the compacting of information by reducing the number of bits which are stored or transmitted. In this way, the compressed data will need less disk space than the original one, so additional content can be stored on the same amount of space. You'll find different compression algorithms that function in different ways and with many of them just the redundant bits are erased, therefore once the data is uncompressed, there is no decrease in quality. Others remove unnecessary bits, but uncompressing the data later on will result in reduced quality in comparison with the original. Compressing and uncompressing content takes a large amount of system resources, and in particular CPU processing time, so each and every Internet hosting platform that uses compression in real time should have adequate power to support that feature. An example how info 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 Web Hosting
The compression algorithm that we work with on the cloud web hosting platform where your new web hosting account shall be created is named LZ4 and it is applied by the leading-edge ZFS file system which powers the platform. The algorithm is greater than the ones other file systems use because its compression ratio is a lot higher and it processes data a lot faster. The speed is most noticeable when content is being uncompressed as this happens quicker than data can be read from a hdd. As a result, LZ4 improves the performance of every site located on a server which uses the algorithm. We use LZ4 in an additional way - its speed and compression ratio make it possible for us to produce a number of daily backup copies of the whole content of all accounts and keep them for thirty days. Not only do our backups take less space, but their generation won't slow the servers down like it often happens with some other file systems.
Data Compression in Semi-dedicated Hosting
If you host your Internet sites in a semi-dedicated hosting account with our company, you can experience the advantages of LZ4 - the powerful compression algorithm used by the ZFS file system that is behind our advanced cloud Internet hosting platform. What distinguishes LZ4 from all of the other algorithms out there is that it has an improved compression ratio and it is much quicker, particularly with regard to uncompressing web content. It does that even quicker than uncompressed information can be read from a hard drive, so your Internet sites will perform faster. The higher speed is at the expense of using a lot of CPU processing time, that is not an issue for our platform as it consists of a large number of clusters working together. In combination with the improved performance, you will also have multiple daily backups at your disposal, so you could recover any deleted content with a few clicks. The backups are available for a whole month and we can afford to keep them since they need considerably less space compared to standard backups.
