Data compression is the reduction of the number of bits that should be saved or transmitted and the process is quite important in the web hosting field due to the fact that info stored on hard disk drives is generally compressed in order to take less space. There are different algorithms for compressing data and they offer different effectiveness depending on the content. A lot of them remove just the redundant bits, so no data will be lost, while others erase unnecessary bits, which results in worse quality once the data is uncompressed. The process needs plenty of processing time, so a web hosting server needs to be powerful enough so as to be able to compress and uncompress data quickly. An instance how binary code can be compressed is by "remembering" that there're five sequential 1s, for example, rather than storing all five 1s.

Data Compression in Cloud Hosting

The compression algorithm used by the ZFS file system which runs on our cloud hosting platform is called LZ4. It can boost the performance of any website hosted in a cloud hosting account on our end since not only does it compress info significantly better than algorithms used by various file systems, but it also uncompresses data at speeds that are higher than the hard disk reading speeds. This can be done by using a great deal of CPU processing time, that 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 allows us to create backups quicker and on reduced disk space, so we shall have multiple daily backups of your databases and files and their generation won't change the performance of the servers. This way, we can always recover all of the content that you may have removed by accident.

Data Compression in Semi-dedicated Hosting

Your semi-dedicated hosting account will be created on a cloud platform which is run on the cutting-edge ZFS file system. The aforementioned uses a compression algorithm named LZ4, that's a lot better than other algorithms when it comes to 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 hard disk. That's why Internet sites running on a platform which employs LZ4 compression perform faster as the algorithm is most efficient when it processes compressible data i.e. web content. Another advantage of using LZ4 is that the backup copies of the semi-dedicated accounts which we keep take a lot less space and they are generated a lot faster, which enables us to store a couple of daily backups of your files and databases.
