Data compression is the decrease of the number of bits which should be saved or transmitted and this particular process is rather important in the internet hosting field because information filed on hard drives is typically compressed in order to take less space. You will find different algorithms for compressing information and they have different efficiency based upon the content. A lot of them remove only the redundant bits, so that no data can be lost, while others erase unnecessary bits, which results in worse quality once the data is uncompressed. The method needs a lot of processing time, therefore a hosting server needs to be powerful enough to be able to compress and uncompress data immediately. An instance how binary code may be compressed is by "remembering" that there're five sequential 1s, for example, rather than storing all five 1s.

Data Compression in Cloud Website Hosting

The compression algorithm that we work with on the cloud web hosting platform where your new cloud website hosting account shall be created is known as LZ4 and it's applied by the leading-edge ZFS file system that powers the system. The algorithm is far better than the ones other file systems employ since its compression ratio is a lot higher and it processes data a lot quicker. The speed is most noticeable when content is being uncompressed since this happens quicker than data can be read from a hard disk drive. As a result, LZ4 improves the performance of every site stored on a server that uses this algorithm. We take advantage of LZ4 in an additional way - its speed and compression ratio let us generate multiple daily backup copies of the entire content of all accounts and store them for a month. Not only do the backups take less space, but in addition their generation doesn't slow the servers down like it often happens with some other file systems.
