Data compression is the compacting of info by reducing the number of bits which are stored or transmitted. Because of this, the compressed data will need substantially less disk space than the original one, so much more content could be stored on identical amount of space. There're various compression algorithms which function in different ways and with several of them just the redundant bits are erased, so once the data is uncompressed, there's no decrease in quality. Others delete unneeded bits, but uncompressing the data afterwards will result in reduced quality compared to the original. Compressing and uncompressing content takes a large amount of system resources, particularly CPU processing time, so every hosting platform which uses compression in real time must have enough power to support that attribute. An example how data can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" what number of sequential 1s or 0s there should be instead of keeping the whole code.
Data Compression in Shared Web Hosting
The compression algorithm employed by the ZFS file system which runs on our cloud hosting platform is called LZ4. It can enhance the performance of any Internet site hosted in a shared web hosting account on our end as not only does it compress info significantly better than algorithms employed by other file systems, but it also uncompresses data at speeds which are higher than the hard drive reading speeds. This is achieved by using a great deal of CPU processing time, which is not a problem for our platform considering the fact that it uses clusters of powerful servers working together. An additional advantage of LZ4 is that it allows us to create backup copies a lot faster and on less disk space, so we will have multiple daily backups of your databases and files and their generation won't influence the performance of the servers. That way, we could always restore all of the content that you could have erased by accident.
Data Compression in Semi-dedicated Hosting
If you host your sites in a semi-dedicated hosting account with our firm, you'll be able to experience the advantages of LZ4 - the powerful compression algorithm employed by the ZFS file system that is behind our advanced cloud web hosting platform. What distinguishes LZ4 from all of the other algorithms out there is that it has a higher compression ratio and it is considerably quicker, especially when it comes to uncompressing website content. It does that even quicker than uncompressed data can be read from a hard disk drive, so your websites will perform better. The higher speed is at the expense of using a considerable amount of CPU processing time, which is not a problem for our platform because it consists of a large number of clusters working together. Together with the better performance, you'll have multiple daily backups at your disposal, so you will be able to restore any deleted content with just a couple of clicks. The backups are available for a whole month and we can afford to keep them as they need considerably less space compared to standard backups.
