Data compression is the decrease of the number of bits which have to be stored or transmitted and the process is very important in the internet hosting field because data filed on hard disks is usually compressed in order to take less space. You can find various algorithms for compressing data and they offer different efficiency based upon the content. A lot of them remove just the redundant bits, so that no data will be lost, while others remove unnecessary bits, which leads to worse quality once the particular data is uncompressed. The process employs plenty of processing time, therefore a web hosting server should be powerful enough so as to be able to compress and uncompress data quickly. One example how binary code could be compressed is by "remembering" that there're five consecutive 1s, for example, in contrast to storing all five 1s.
Data Compression in Shared Web Hosting
The compression algorithm which we employ on the cloud hosting platform where your new shared web hosting account will be created is called LZ4 and it is used by the exceptional ZFS file system that powers the system. The algorithm is superior to the ones other file systems employ as its compression ratio is a lot higher and it processes data significantly faster. The speed is most noticeable when content is being uncompressed since this happens more quickly than information can be read from a hdd. Therefore, LZ4 improves the performance of each and every site hosted on a server that uses this algorithm. We use LZ4 in one more way - its speed and compression ratio let us generate several daily backup copies of the full content of all accounts and store them for thirty days. Not only do these backups take less space, but in addition their generation won't slow the servers down like it often happens with other file systems.
