Data compression is the lowering of the number of bits which have to be saved or transmitted and this process is very important in the internet hosting field as info located on hard disks is generally compressed so as to take less space. You can find various algorithms for compressing info and they offer different effectiveness based on the content. A number of them remove just the redundant bits, so no data will be lost, while others delete unnecessary bits, which leads to worse quality once the data is uncompressed. This process consumes plenty of processing time, therefore a web hosting server has to be powerful enough so as to be able to compress and uncompress data immediately. An example how binary code can 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 compression algorithm employed by the ZFS file system which runs on our cloud internet hosting platform is called LZ4. It can improve the performance of any site hosted in a cloud hosting account with us since not only does it compress data significantly better than algorithms used by other file systems, but also uncompresses data at speeds which are higher than the hard disk reading speeds. This is achieved by using a great deal of CPU processing time, that is not a problem for our platform owing to the fact that it uses clusters of powerful servers working together. An additional advantage of LZ4 is that it allows us to make backup copies much quicker and on less disk space, so we can have multiple daily backups of your databases and files and their generation won't change the performance of the servers. That way, we can always recover all content that you could have erased by accident.
