Data compression is the lowering of the number of bits that should be saved or transmitted and the process is really important in the web hosting field because info located on HDDs is typically compressed to take less space. You can find different algorithms for compressing data and they have different effectiveness based on the content. A lot of them remove just the redundant bits, so no data can be lost, while others remove unneeded bits, which leads to worse quality when your data is uncompressed. The process requires plenty of processing time, so an internet hosting server needs to be powerful enough so as to be able to compress and uncompress data quickly. An instance how binary code can be compressed is by "remembering" that there're five sequential 1s, for example, in contrast to storing all five 1s.
Data Compression in Shared Hosting
The cloud hosting platform where your shared hosting account shall be made works by using the cutting-edge ZFS file system. The LZ4 compression method which the aforementioned uses is greater in lots of aspects, and not only does it compress data better than any compression method which similar file systems use, but it is also a lot faster. The gains are significant especially on compressible content such as website files. While it could sound unreasonable, uncompressing data with LZ4 is quicker than reading uncompressed data from a hard disk, so the performance of each and every site hosted on our servers will be boosted. The better and quicker compression rates also make it possible for us to make numerous daily backups of the entire content in every single web hosting account, so should you delete anything by mistake, the last back-up copy which we have will not be more than several hours old. This can be done as the backups take much less space and their generation is quick enough, so as to not influence the performance of our servers.
