Data compression is the compacting of info by reducing the number of bits which are stored or transmitted. As a result, the compressed info needs considerably less disk space than the initial one, so additional content might be stored using identical amount of space. You will find different compression algorithms which work in different ways and with a number of them only the redundant bits are deleted, which means that once the data is uncompressed, there's no decrease in quality. Others erase excessive bits, but uncompressing the data at a later time will lead to reduced quality in comparison with the original. Compressing and uncompressing content consumes a huge amount of system resources, particularly CPU processing time, therefore every web hosting platform which uses compression in real time needs to have sufficient power to support that attribute. An example how data can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" the number of sequential 1s or 0s there should be instead of keeping the actual code.

Data Compression in Shared Website Hosting

The compression algorithm employed by the ZFS file system which runs on our cloud hosting platform is known as LZ4. It can supercharge the performance of any website hosted in a shared website hosting account with us since not only does it compress data more effectively than algorithms used by various other file systems, but it uncompresses data at speeds that are higher than the HDD reading speeds. This is achieved by using a lot of CPU processing time, that is not a problem for our platform considering the fact that it uses clusters of powerful servers working together. A further advantage of LZ4 is that it enables us to generate backups more speedily and on reduced disk space, so we can have several daily backups of your files and databases and their generation will not affect the performance of the servers. That way, we could always restore all the content that you may have removed by accident.

Data Compression in Semi-dedicated Servers

If you host your sites in a semi-dedicated server account from our firm, you can experience the advantages of LZ4 - the powerful compression algorithm used by the ZFS file system that's behind our advanced cloud Internet hosting platform. What separates LZ4 from all of the other algorithms out there is that it has an improved compression ratio and it is way quicker, particularly with regard to uncompressing web content. It does that even quicker than uncompressed information can be read from a hard drive, so your sites will perform better. The higher speed is at the expense of using a considerable amount of CPU processing time, that is not a problem for our platform as it consists of numerous clusters working together. Besides the better performance, you'll have multiple daily backups at your disposal, so you could restore any deleted content with a couple of clicks. The backup copies are available for an entire month and we can afford to keep them because they need considerably less space compared to traditional backups.
