Data compression is the compacting of info by lowering the number of bits that are stored or transmitted. In this way, the compressed data needs considerably less disk space than the initial one, so much more content might be stored using identical amount of space. You'll find various compression algorithms which function in different ways and with a lot of them only the redundant bits are removed, therefore once the information is uncompressed, there's no decrease in quality. Others delete unnecessary bits, but uncompressing the data at a later time will result in lower quality in comparison with the original. Compressing and uncompressing content takes a significant amount of system resources, particularly CPU processing time, therefore any web hosting platform that uses compression in real time should have adequate power to support this feature. An example how data can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" how many consecutive 1s or 0s there should be instead of saving the entire code.
Data Compression in Web Hosting
The compression algorithm used by the ZFS file system which runs on our cloud web hosting platform is named LZ4. It can enhance the performance of any site hosted in a web hosting account with us because not only does it compress info much better than algorithms employed by other file systems, but it uncompresses data at speeds which are higher than the hard drive reading speeds. This can be done by using a great deal of CPU processing time, that is not a problem for our platform for the reason that it uses clusters of powerful servers working together. One more advantage of LZ4 is that it enables us to generate backups more quickly 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 could always restore all content that you may have erased by mistake.
Data Compression in Semi-dedicated Servers
In case you host your Internet sites in a semi-dedicated server account with our firm, you will be able to experience the advantages of LZ4 - the powerful compression algorithm used by the ZFS file system that's behind our advanced cloud hosting platform. What differentiates LZ4 from all the other algorithms out there is that it has a better compression ratio and it is considerably faster, in particular when it comes to uncompressing website content. It does that even faster than uncompressed information can be read from a hard disk drive, so your websites will perform better. The higher speed comes at the expense of using a great deal of CPU processing time, which is not a problem for our platform since it consists of numerous clusters working together. Together with the superior performance, you'll also have multiple daily backups at your disposal, so you'll be able to restore any deleted content with a couple of clicks. The backups are available for an entire month and we can afford to keep them because they take a lot less space compared to standard backups.
