Data compression is the reduction of the number of bits that need to be saved or transmitted and this particular process is quite important in the internet hosting field due to the fact that info stored on HDDs is often compressed so as to take less space. There are many different algorithms for compressing data and they offer different efficiency based upon the content. A number of them remove just the redundant bits, so no data will be lost, while others remove unneeded bits, which results in worse quality when the particular data is uncompressed. The process requires plenty of processing time, therefore a web hosting server has to be powerful enough so as to be able to compress and uncompress data instantly. An example 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 Web Hosting

The compression algorithm which we work with on the cloud internet hosting platform where your new cloud web hosting account will be created is known as LZ4 and it's applied by the state-of-the-art ZFS file system that powers the platform. The algorithm is a lot better than the ones other file systems use as its compression ratio is higher and it processes data considerably quicker. The speed is most noticeable when content is being uncompressed as this happens faster than info can be read from a hard disk drive. Consequently, LZ4 improves the performance of each website located on a server that uses this particular algorithm. We take advantage of LZ4 in an additional way - its speed and compression ratio allow us to produce a couple of daily backups of the entire content of all accounts and store them for a month. Not only do these backup copies take less space, but also their generation will not slow the servers down like it can often happen with various other file systems.
