Data compression is the reduction of the number of bits which have to be saved or transmitted and this process is really important in the web hosting field since data filed on HDDs is often compressed in order to take less space. You'll find different algorithms for compressing information and they provide different effectiveness based upon the content. A lot of them remove only the redundant bits, so that no data can be lost, while others delete unneeded bits, which leads to worse quality when the particular data is uncompressed. The process consumes plenty of processing time, which means that a web hosting server has to be powerful enough so as to be able to compress and uncompress data immediately. An instance how binary code could be compressed is by "remembering" that there are five sequential 1s, for example, in contrast to storing all five 1s.
Data Compression in Cloud Hosting
The cloud web hosting platform where your cloud hosting
account is made works by using the impressive ZFS file system. The LZ4 compression method that the aforementioned employs is better in many aspects, and not only does it compress data better than any compression method which similar file systems use, but it is also considerably faster. The benefits can be significant in particular on compressible content such as website files. Although it could sound illogical, uncompressing data with LZ4 is faster than reading uncompressed info from a hard disk drive, so the performance of each and every website hosted on our servers will be boosted. The better and quicker compression rates also make it possible for us to generate multiple daily backups of the whole content in each and every web hosting account, so should you delete anything by accident, the last back-up copy that we have will not be more than a couple of hours old. This is possible as the backups take a lot less space and their generation is quick enough, to not affect the performance of our servers.
