Data compression is the lowering of the number of bits that should be saved or transmitted and the process is very important in the web hosting field due to the fact that info filed on HDDs is often compressed to take less space. You'll find different algorithms for compressing information and they have different efficiency depending on the content. Many of them remove only the redundant bits, so that no data can be lost, while others delete unnecessary bits, which results in worse quality once the particular data is uncompressed. The method needs plenty of processing time, which means that a hosting server needs to be powerful enough to be able to compress and uncompress data in real time. An illustration how binary code may 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 which we use on the cloud web hosting platform where your new cloud hosting account shall be created is known as LZ4 and it is applied by the cutting-edge ZFS file system that powers the platform. The algorithm is more advanced than the ones other file systems use as its compression ratio is much higher and it processes data a lot quicker. The speed is most noticeable when content is being uncompressed as this happens at a faster rate than data can be read from a hard disk. As a result, LZ4 improves the performance of every site located on a server which uses the algorithm. We take advantage of LZ4 in an additional way - its speed and compression ratio allow us to generate a number of daily backups of the whole content of all accounts and keep them for 30 days. Not only do our backups take less space, but in addition their generation will not slow the servers down like it can often happen with various other file systems.
