Data compression is the lowering of the number of bits which need to be saved or transmitted and the process is really important in the internet hosting field due to the fact that info filed on HDDs is often compressed so as to take less space. There are various algorithms for compressing info and they offer different efficiency depending on the content. Some of them remove only the redundant bits, so that no data can be lost, while others delete unneeded bits, which leads to worse quality when the particular data is uncompressed. This method consumes plenty of processing time, which means that a hosting server should be powerful enough in order to be able to compress and uncompress data in real time. An example how binary code could be compressed is by "remembering" that there are five sequential 1s, for example, in contrast to storing all five 1s.
Data Compression in Hosting
The compression algorithm used by the ZFS file system which runs on our cloud web hosting platform is named LZ4. It can supercharge the performance of any website hosted in a hosting
account with us since not only does it compress data much better than algorithms employed by other file systems, but it uncompresses data at speeds which are higher than the hard disk reading speeds. This is achieved by using a lot of CPU processing time, which is not a problem for our platform due to the fact that it uses clusters of powerful servers working together. An additional advantage of LZ4 is that it enables us to make backups at a higher speed and on reduced disk space, so we shall have a couple of daily backups of your databases and files and their generation won't change the performance of the servers. In this way, we could always restore the content that you could have removed by accident.
Data Compression in Semi-dedicated Servers
The semi-dedicated server
plans which we supply are created on a powerful cloud platform which runs on the ZFS file system. ZFS works with a compression algorithm called LZ4 that exceeds any other algorithm these days in terms of speed and compression ratio when it comes to processing website content. This is valid particularly when data is uncompressed as LZ4 does that more quickly than it would be to read uncompressed data from a hard drive and as a result, Internet sites running on a platform where LZ4 is present will function at a higher speed. We are able to take full advantage of the feature although it requires quite a considerable amount of CPU processing time as our platform uses many powerful servers working together and we never create accounts on just a single machine like the majority of companies do. There's a further benefit of using LZ4 - given that it compresses data rather well and does that very fast, we can also generate several daily backups of all accounts without affecting the performance of the servers and keep them for a whole month. That way, you can always bring back any content that you erase by mistake.
