Data compression is the lowering of the number of bits which have to be stored or transmitted and this process is rather important in the web hosting field since info located on hard drives is usually compressed so as to take less space. There are various algorithms for compressing data and they have different effectiveness depending on the content. Some of them remove just the redundant bits, so that no data can be lost, while others remove unneeded bits, which results in worse quality when the data is uncompressed. The method employs a lot of processing time, therefore a hosting server has to be powerful enough so as to be able to compress and uncompress data in real time. One example how binary code may be compressed is by "remembering" that there are five consecutive 1s, for example, in contrast to storing all five 1s.

Data Compression in Hosting

The compression algorithm used by the ZFS file system which runs on our cloud web hosting platform is known as LZ4. It can improve the performance of any website hosted in a hosting account on our end because not only does it compress data more efficiently than algorithms used by various file systems, but also uncompresses data at speeds that are higher than the hard disk reading speeds. This can be done by using a lot of CPU processing time, that is not a problem for our platform considering that it uses clusters of powerful servers working together. An additional advantage of LZ4 is that it allows us to make backups much quicker and on less disk space, so we shall have several daily backups of your databases and files and their generation will not affect the performance of the servers. That way, we could always restore any content that you may have deleted by accident.
