Data compression is the compacting of information by lowering the number of bits that are stored or transmitted. Because of this, the compressed data will take substantially less disk space than the original one, so more content can be stored using identical amount of space. There're various compression algorithms that function in different ways and with several of them just the redundant bits are erased, therefore once the information is uncompressed, there is no loss of quality. Others delete unneeded bits, but uncompressing the data at a later time will lead to reduced quality in comparison with the original. Compressing and uncompressing content needs a large amount of system resources, in particular CPU processing time, so each and every web hosting platform which employs compression in real time needs to have ample power to support this attribute. An example how data can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" the number of consecutive 1s or 0s there should be instead of saving the actual code.
Data Compression in Cloud Hosting
The compression algorithm that we employ on the cloud internet hosting platform where your new cloud hosting account will be created is known as LZ4 and it is used by the leading-edge ZFS file system that powers the system. The algorithm is superior to the ones other file systems work with because its compression ratio is a lot higher and it processes data significantly quicker. The speed is most noticeable when content is being uncompressed as this happens faster than data can be read from a hard drive. For that reason, LZ4 improves the performance of each and every site hosted on a server that uses this algorithm. We take advantage of LZ4 in one more way - its speed and compression ratio make it possible for us to produce a number of daily backup copies of the whole content of all accounts and store them for one month. Not only do our backups take less space, but also their generation doesn't slow the servers down like it can often happen with some other file systems.
Data Compression in Semi-dedicated Servers
The semi-dedicated server plans that we supply are created on a powerful cloud platform that runs on the ZFS file system. ZFS uses a compression algorithm named LZ4 that is greater than any other algorithm these days in terms of speed and data compression ratio when it comes to processing web content. This is valid especially when data is uncompressed because LZ4 does that more rapidly than it would be to read uncompressed data from a hard drive and because of this, Internet sites running on a platform where LZ4 is present will function at a higher speed. We are able to benefit from the feature although it needs quite a large amount of CPU processing time because our platform uses a lot of powerful servers working together and we don't make accounts on a single machine like many companies do. There is one more benefit of using LZ4 - given that it compresses data very well and does that very quickly, we can also make several daily backups of all accounts without affecting the performance of the servers and keep them for a month. By doing this, you can always restore any content that you erase by accident.
