Data compression is the compacting of information by reducing the number of bits that are stored or transmitted. Because of this, the compressed information requires less disk space than the original one, so much more content could be stored using identical amount of space. There are various compression algorithms that work in different ways and with some of them only the redundant bits are deleted, so once the info is uncompressed, there is no decrease in quality. Others delete unnecessary bits, but uncompressing the data later on will lead to reduced quality in comparison with the original. Compressing and uncompressing content takes a huge amount of system resources, in particular CPU processing time, so each and every web hosting platform that employs compression in real time should have adequate 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" what number of consecutive 1s or 0s there should be instead of keeping the actual code.

Data Compression in Cloud Website Hosting

The compression algorithm that we employ on the cloud hosting platform where your new cloud website hosting account will be created is known as LZ4 and it's applied by the advanced ZFS file system which powers the system. The algorithm is better than the ones other file systems work with as its compression ratio is a lot higher and it processes data considerably faster. The speed is most noticeable when content is being uncompressed as this happens at a faster rate than data can be read from a hard disk drive. As a result, LZ4 improves the performance of every Internet site located on a server that uses this particular algorithm. We take advantage of LZ4 in one more way - its speed and compression ratio let us make multiple daily backups of the full content of all accounts and keep them for 30 days. Not only do the backup copies take less space, but also their generation doesn't slow the servers down like it can often happen with alternative file systems.

Data Compression in Semi-dedicated Servers

In case you host your sites in a semi-dedicated server account from our firm, you'll be able to experience the advantages of LZ4 - the powerful compression algorithm used by the ZFS file system which is behind our advanced cloud web hosting platform. What differentiates LZ4 from all other algorithms out there is that it has a higher compression ratio and it is way quicker, particularly when it comes to uncompressing website content. It does that even quicker than uncompressed information can be read from a hard disk drive, so your Internet sites will perform faster. The higher speed comes at the expense of using lots of CPU processing time, that is not an issue for our platform because it consists of a lot of clusters working together. Besides the superior performance, you will also have multiple daily backups at your disposal, so you could recover any deleted content with just a few clicks. The backup copies are available for an entire month and we can afford to store them since they need significantly less space compared to standard backups.
