Data compression is the decrease of the number of bits which have to be stored or transmitted and this particular process is very important in the web hosting field since data recorded on HDDs is usually compressed so as to take less space. There are various algorithms for compressing data and they offer different effectiveness depending on the content. A lot of them remove just the redundant bits, so no data can be lost, while others delete unnecessary bits, which results in worse quality when the particular data is uncompressed. This method consumes plenty of processing time, therefore a web hosting server should be powerful enough so as to be able to compress and uncompress data in real time. An instance how binary code may be compressed is by "remembering" that there're five sequential 1s, for example, in contrast to storing all five 1s.

Data Compression in Cloud Web Hosting

The compression algorithm used by the ZFS file system that runs on our cloud hosting platform is named LZ4. It can upgrade the performance of any site hosted in a cloud web hosting account on our end because not only does it compress info significantly better than algorithms used by other file systems, but also uncompresses data at speeds that are higher than the HDD reading speeds. This can be done by using a lot of CPU processing time, that is not a problem for our platform for the reason that it uses clusters of powerful servers working together. A further advantage of LZ4 is that it enables us to create backup copies faster and on lower disk space, so we shall have multiple daily backups of your files and databases and their generation will not change the performance of the servers. That way, we could always restore all the content that you may have deleted by accident.
