Data compression is the decrease of the number of bits which need to be stored or transmitted and the process is quite important in the internet hosting field due to the fact that data stored on hard disk drives is typically compressed so as to take less space. You'll find different algorithms for compressing information and they have different efficiency based upon the content. A lot of them remove just the redundant bits, so no data can be lost, while others delete unneeded bits, which leads to worse quality when your data is uncompressed. This method consumes plenty of processing time, which means that an internet hosting server needs to be powerful enough so as to be able to compress and uncompress data quickly. An example how binary code may be compressed is by "remembering" that there're five consecutive 1s, for example, in contrast to storing all five 1s.

Data Compression in Web Hosting

The compression algorithm which we work with on the cloud web hosting platform where your new web hosting account shall be created is named LZ4 and it's applied by the advanced ZFS file system that powers the platform. The algorithm is more advanced than the ones other file systems employ because its compression ratio is a lot higher and it processes data a lot quicker. The speed is most noticeable when content is being uncompressed as this happens at a faster rate than data can be read from a hard drive. Because of this, LZ4 improves the performance of any website located on a server which uses this algorithm. We take advantage of LZ4 in an additional way - its speed and compression ratio make it possible for us to generate a couple of daily backup copies of the full content of all accounts and store them for 30 days. Not only do the backups take less space, but in addition their generation will not slow the servers down like it often happens with various other file systems.

Data Compression in Semi-dedicated Servers

Your semi-dedicated server account will be created on a cloud platform which is run on the leading-edge ZFS file system. The aforementioned uses a compression algorithm named LZ4, that is significantly better than all the other algorithms with regard to compression ratio and speed. The gain is significant especially 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 disk. This is why Internet sites running on a platform that employs LZ4 compression perform faster because the algorithm is most efficient when it processes compressible data i.e. web content. An additional advantage of using LZ4 is that the backups of the semi-dedicated accounts that we keep need significantly less space and are generated faster, which enables us to keep a number of daily backups of all your files and databases.
