Data compression is the reduction of the number of bits that should be saved or transmitted and this particular process is rather important in the internet hosting field because info located on hard disk drives is generally compressed in order to take less space. You will find various algorithms for compressing data and they have different effectiveness depending on the content. A number of them remove just the redundant bits, so that no data can be lost, while others erase unnecessary bits, which results in worse quality when the particular data is uncompressed. This method requires plenty of processing time, which means that a hosting server should be powerful enough in order to be able to compress and uncompress data right away. An illustration how binary code may be compressed is by "remembering" that there're five sequential 1s, for example, rather than storing all five 1s.
Data Compression in Web Hosting
The compression algorithm that we work with on the cloud internet hosting platform where your new web hosting account shall be created is named LZ4 and it is applied by the state-of-the-art ZFS file system which powers the system. The algorithm is better than the ones other file systems employ because its compression ratio is much higher and it processes data considerably quicker. The speed is most noticeable when content is being uncompressed as this happens even faster than information can be read from a hard disk drive. Therefore, LZ4 improves the performance of any site stored on a server that uses this particular algorithm. We take advantage of LZ4 in an additional way - its speed and compression ratio allow us to make several daily backup copies of the full content of all accounts and keep them for 30 days. Not only do our backups take less space, but their generation won't slow the servers down like it often happens with various other file systems.
Data Compression in Semi-dedicated Servers
The semi-dedicated server plans that we supply are created on a powerful cloud hosting platform which runs on the ZFS file system. ZFS uses a compression algorithm called LZ4 that outperforms any other algorithm available in terms of speed and compression ratio when it comes to processing web content. This is valid especially when data is uncompressed since LZ4 does that faster than it would be to read uncompressed data from a hard disk and owing to this, Internet sites running on a platform where LZ4 is enabled will work faster. We're able to take full advantage of this feature despite of the fact that it requires quite a considerable amount of CPU processing time because our platform uses a lot of powerful servers working together and we never create accounts on a single machine like many companies do. There's another benefit of using LZ4 - considering that it compresses data very well and does that very fast, we can also generate multiple daily backup copies of all accounts without influencing the performance of the servers and keep them for a whole month. That way, you will always be able to restore any content that you erase by mistake.
