Data compression is the decrease of the number of bits which have to be stored or transmitted and the process is rather important in the internet hosting field since info recorded on hard disk drives is generally compressed in order to take less space. You can find various algorithms for compressing information and they provide different effectiveness based upon the content. A lot of them remove just the redundant bits, so no data can be lost, while others erase unneeded bits, which leads to worse quality when the data is uncompressed. The method uses a lot of processing time, therefore an internet hosting server has to be powerful enough so as to be able to compress and uncompress data right away. One example how binary code may be compressed is by "remembering" that there are five consecutive 1s, for example, rather than storing all five 1s.
Data Compression in Shared Web Hosting
The compression algorithm that we work with on the cloud internet hosting platform where your new shared web hosting
account shall be created is known as LZ4 and it's applied by the state-of-the-art ZFS file system that powers the platform. The algorithm is more advanced than the ones other file systems work with as its compression ratio is higher and it processes data significantly faster. The speed is most noticeable when content is being uncompressed as this happens quicker than info can be read from a hard drive. Because of this, LZ4 improves the performance of every website stored on a server that uses this particular algorithm. We take advantage of LZ4 in one more way - its speed and compression ratio let us make a couple of daily backups of the whole content of all accounts and store them for a month. Not only do these backup copies take less space, but in addition their generation does not slow the servers down like it can often happen with other file systems.
Data Compression in Semi-dedicated Hosting
The semi-dedicated hosting
plans which we offer are created on a powerful cloud hosting platform that runs on the ZFS file system. ZFS works with a compression algorithm called LZ4 that is greater than any other algorithm out there in terms of speed and compression ratio when it comes to processing web content. This is valid particularly when data is uncompressed because LZ4 does that faster than it would be to read uncompressed data from a hard disk and for that reason, websites running on a platform where LZ4 is enabled will work at a higher speed. We are able to take advantage of the feature regardless of the fact that it requires quite a large amount of CPU processing time as our platform uses many powerful servers working together and we never create accounts on a single machine like the vast majority of companies do. There's one more reward of using LZ4 - since it compresses data rather well and does that extremely fast, we can also make multiple daily backup copies of all accounts without affecting the performance of the servers and keep them for an entire month. By doing this, you can always restore any content that you delete by mistake.
