Data compression is the reduction of the number of bits that have to be saved or transmitted and this process is rather important in the internet hosting field as data kept on hard disks is usually compressed to take less space. There are many different algorithms for compressing information and they provide different efficiency based upon the content. A number of them remove only the redundant bits, so no data will be lost, while others erase unneeded bits, which results in worse quality once the particular data is uncompressed. This method requires a lot of processing time, which means that a web hosting server needs to be powerful enough so as to be able to compress and uncompress data in real time. An illustration how binary code can be compressed is by "remembering" that there're five sequential 1s, for example, in contrast to storing all five 1s.

Data Compression in Cloud Hosting

The compression algorithm used by the ZFS file system which runs on our cloud web hosting platform is called LZ4. It can improve the performance of any Internet site hosted in a cloud hosting account with us since not only does it compress info more efficiently than algorithms used by alternative 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, that is not a problem for our platform owing to the fact that it uses clusters of powerful servers working together. A further advantage of LZ4 is that it enables us to create backups a lot faster and on less disk space, so we can have several daily backups of your databases and files and their generation won't affect the performance of the servers. That way, we can always recover all of the content that you could have deleted by mistake.

Data Compression in Semi-dedicated Hosting

Your semi-dedicated hosting account will be created on a cloud platform which runs on the innovative ZFS file system. The latter uses a compression algorithm named LZ4, that's significantly better than various other algorithms in terms of compression ratio and speed. The gain is significant particularly when data is being uncompressed and not only is LZ4 faster than other algorithms, but it is also faster in uncompressing data than a system is in reading from a HDD. This is why websites running on a platform which employs LZ4 compression perform faster as the algorithm is most effective when it processes compressible data i.e. site content. Another advantage of using LZ4 is that the backups of the semi-dedicated accounts which we keep require a lot less space and are generated faster, which enables us to keep a couple of daily backups of your files and databases.
