Data compression is the compacting of information by decreasing the number of bits that are stored or transmitted. Because of this, the compressed data will require much less disk space than the initial one, so additional content could be stored on the same amount of space. You'll find many different compression algorithms which work in different ways and with several of them only the redundant bits are removed, so once the info is uncompressed, there's no loss of quality. Others erase excessive bits, but uncompressing the data subsequently will result in reduced quality compared to the original. Compressing and uncompressing content needs a large amount of system resources, especially CPU processing time, therefore each and every 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" how many sequential 1s or 0s there should be instead of storing the whole code.
Data Compression in Web Hosting
The compression algorithm employed by the ZFS file system which runs on our cloud web hosting platform is called LZ4. It can boost the performance of any website hosted in a web hosting account on our end because not only does it compress info more efficiently than algorithms used by various other file systems, but it also uncompresses data at speeds that are higher than the hard drive reading speeds. This can be done by using a lot 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 more speedily and on reduced disk space, so we will have several daily backups of your databases and files and their generation won't change the performance of the servers. In this way, we can always restore all content that you may have erased by accident.
Data Compression in Semi-dedicated Servers
If you host your Internet sites in a semi-dedicated server account with our firm, you can experience the advantages of LZ4 - the powerful compression algorithm used by the ZFS file system which is behind our advanced cloud Internet hosting platform. What differentiates LZ4 from all the other algorithms out there is that it has a higher compression ratio and it is way quicker, in particular when it comes to uncompressing website content. It does that even quicker than uncompressed data can be read from a hard drive, so your websites will perform faster. The higher speed is at the expense of using a great deal of CPU processing time, which is not an issue for our platform since it consists of a lot of clusters working together. In addition to the superior performance, you will also have multiple daily backups at your disposal, so you'll be able to restore any deleted content with just a couple of clicks. The backups are available for an entire month and we can afford to keep them as they take significantly less space compared to standard backups.
