Learn exactly what Data Compression is and find out how it could affect your websites and the experience of your visitors.
Data compression is the decrease of the number of bits which should be stored or transmitted and the process is rather important in the web hosting field since information filed on hard disks is usually compressed in order to take less space. There're different algorithms for compressing information and they have different efficiency based upon the content. Some of them remove just the redundant bits, so no data will be lost, while others erase unnecessary bits, which results in worse quality when your data is uncompressed. This process uses plenty of processing time, so a hosting server should be powerful enough in order to be able to compress and uncompress data immediately. One example how binary code can be compressed is by "remembering" that there're five consecutive 1s, for example, in contrast to storing all five 1s.
Data Compression in Cloud Hosting
The compression algorithm employed by the ZFS file system that runs on our cloud internet hosting platform is called LZ4. It can boost the performance of any website hosted in a cloud hosting account with us because not only does it compress info more efficiently than algorithms employed by alternative file systems, but it uncompresses data at speeds that are higher than the hard disk reading speeds. This can be done by using a lot of CPU processing time, that is not a problem for our platform considering the fact that it uses clusters of powerful servers working together. An additional advantage of LZ4 is that it enables us to generate backups quicker and on less disk space, so we can have multiple daily backups of your databases and files and their generation won't affect the performance of the servers. This way, we can always recover any kind of content that you may have removed by mistake.
