Data compression is the compacting of data by decreasing the number of bits that are stored or transmitted. Consequently, the compressed information takes less disk space than the original one, so much more content might be stored on the same amount of space. There are various compression algorithms which function in different ways and with several of them just the redundant bits are deleted, so once the data is uncompressed, there's no decrease in quality. Others erase unnecessary bits, but uncompressing the data later on will lead to lower quality compared to the original. Compressing and uncompressing content requires a huge amount of system resources, in particular CPU processing time, so any Internet hosting platform that uses compression in real time must have enough power to support this attribute. An example how data can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" what number of consecutive 1s or 0s there should be instead of storing the whole code.

Data Compression in Cloud Web Hosting

The compression algorithm that we work with on the cloud hosting platform where your new cloud web hosting account will be created is called LZ4 and it's used by the cutting-edge ZFS file system that powers the system. The algorithm is a lot better than the ones other file systems employ as its compression ratio is much higher and it processes data considerably quicker. The speed is most noticeable when content is being uncompressed as this happens faster than data can be read from a hard disk drive. As a result, LZ4 improves the performance of any site located on a server that uses the algorithm. We take full advantage of LZ4 in an additional way - its speed and compression ratio allow us to generate multiple daily backup copies of the whole content of all accounts and keep them for one month. Not only do our backups take less space, but their generation will not slow the servers down like it often happens with alternative file systems.

Data Compression in Semi-dedicated Servers

In case you host your websites in a semi-dedicated server account from our firm, you'll be able to experience the advantages of LZ4 - the powerful compression algorithm employed by the ZFS file system that's behind our advanced cloud hosting platform. What separates LZ4 from all of the other algorithms out there is that it has an improved compression ratio and it is much faster, particularly when it comes to uncompressing web content. It does that even quicker than uncompressed data can be read from a hard drive, so your Internet sites will perform faster. The higher speed is at the expense of using a lot of CPU processing time, that is not a problem for our platform as it consists of a large number of clusters working together. Together with the superior performance, you'll have multiple daily backup copies at your disposal, so you will be able to recover any deleted content with a couple of clicks. The backups are available for a whole month and we can afford to keep them because they take a lot less space than conventional backups.
