Data compression is the compacting of information by decreasing the number of bits that are stored or transmitted. Because of this, the compressed data needs much less disk space than the initial one, so additional content could be stored on identical amount of space. There are different compression algorithms that work in different ways and with a lot of them just the redundant bits are deleted, therefore once the information is uncompressed, there's no loss of quality. Others delete unnecessary bits, but uncompressing the data afterwards will result in reduced quality in comparison with the original. Compressing and uncompressing content requires a huge amount of system resources, in particular CPU processing time, so any Internet hosting platform that employs compression in real time needs to have enough power to support that feature. An example how data can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" the number of sequential 1s or 0s there should be instead of saving the whole code.

Data Compression in Shared Website Hosting

The compression algorithm used by the ZFS file system which runs on our cloud internet hosting platform is named LZ4. It can upgrade the performance of any website hosted in a shared website hosting account on our end because not only does it compress data significantly better than algorithms employed by other file systems, but it uncompresses data at speeds that are higher than the hard drive reading speeds. This can be done by using a great deal of CPU processing time, which is not a problem for our platform considering that it uses clusters of powerful servers working together. A further advantage of LZ4 is that it allows us to create backups quicker and on lower disk space, so we shall have a couple of daily backups of your files and databases and their generation will not affect the performance of the servers. That way, we can always restore all of the content that you may have removed by mistake.

Data Compression in Semi-dedicated Servers

If you host your sites in a semi-dedicated server account with our company, you will be able to experience the advantages of LZ4 - the powerful compression algorithm employed by the ZFS file system which is behind our advanced cloud hosting platform. What separates LZ4 from all of the other algorithms out there is that it has a higher compression ratio and it is considerably quicker, particularly when it comes to uncompressing website content. It does that even quicker than uncompressed data can be read from a hard drive, so your sites will perform faster. The higher speed comes at the expense of using a considerable amount of CPU processing time, that's not an issue for our platform as it consists of numerous clusters working together. Together with the improved performance, you'll have multiple daily backups at your disposal, so you could restore any deleted content with a few clicks. The backups are available for a whole month and we can afford to store them because they take significantly less space than traditional backups.
