Data compression is the reduction of the number of bits which need to be stored or transmitted and the process is very important in the internet hosting field as info recorded on hard disk drives is typically compressed in order to take less space. You will find various algorithms for compressing information and they have different effectiveness based upon the content. A lot of them remove only the redundant bits, so no data can be lost, while others remove unnecessary bits, which leads to worse quality when your data is uncompressed. This method employs plenty of processing time, which means that a web hosting server should be powerful enough in order to be able to compress and uncompress data immediately. An illustration how binary code may be compressed is by "remembering" that there are five consecutive 1s, for example, as an alternative to storing all five 1s.
Data Compression in Website Hosting
The ZFS file system that runs on our cloud web hosting platform uses a compression algorithm named LZ4. The aforementioned is substantially faster and better than every other algorithm you'll find, especially for compressing and uncompressing non-binary data i.e. internet content. LZ4 even uncompresses data quicker than it is read from a hard drive, which improves the performance of Internet sites hosted on ZFS-based platforms. Due to the fact that the algorithm compresses data really well and it does that very quickly, we can generate several backup copies of all the content kept in the website hosting accounts on our servers on a daily basis. Both your content and its backups will need less space and since both ZFS and LZ4 work very quickly, the backup generation will not change the performance of the web servers where your content will be stored.
Data Compression in Semi-dedicated Hosting
Your semi-dedicated hosting account shall be created on a cloud platform that is run on the advanced ZFS file system. The latter uses a compression algorithm called LZ4, that's far better than various other algorithms regarding compression ratio and speed. The gain is apparent particularly when data is being uncompressed and not only is LZ4 faster than other algorithms, but it is also quicker in uncompressing data than a system is in reading from a hard drive. This is why Internet sites running on a platform that employs LZ4 compression perform better since the algorithm is most effective when it processes compressible data i.e. web content. A further advantage of using LZ4 is that the backup copies of the semi-dedicated accounts which we keep need much less space and are generated a lot faster, which enables us to keep multiple daily backups of your files and databases.
