Data compression is the decrease of the number of bits which have to be stored or transmitted and this particular process is rather important in the web hosting field due to the fact that info stored on HDDs is typically compressed so as to take less space. You can find various algorithms for compressing data and they provide different effectiveness based on the content. Some of them remove only the redundant bits, so no data can be lost, while others remove unnecessary bits, which results in worse quality once the data is uncompressed. The process employs plenty of processing time, therefore a hosting server has to be powerful enough so as to be able to compress and uncompress data right away. An illustration how binary code can be compressed is by "remembering" that there are five consecutive 1s, for example, rather than storing all five 1s.

Data Compression in Cloud Website Hosting

The compression algorithm that we employ on the cloud internet hosting platform where your new cloud website hosting account shall be created is known as LZ4 and it is used by the revolutionary ZFS file system that powers the system. The algorithm is greater than the ones other file systems work with because its compression ratio is much higher and it processes data considerably quicker. The speed is most noticeable when content is being uncompressed since this happens more quickly than information can be read from a hard drive. Because of this, LZ4 improves the performance of every Internet site stored on a server that uses the algorithm. We take full advantage of LZ4 in one more way - its speed and compression ratio make it possible for us to produce several daily backup copies of the whole content of all accounts and keep them for 30 days. Not only do our backups take less space, but in addition their generation won't slow the servers down like it often happens with some other file systems.
