Data compression is the compacting of information by decreasing the number of bits which are stored or transmitted. Thus, the compressed information will require much less disk space than the original one, so additional content could be stored on the same amount of space. There are various compression algorithms that work in different ways and with several of them only the redundant bits are deleted, so once the info is uncompressed, there is no decrease in quality. Others remove excessive bits, but uncompressing the data afterwards will result in lower quality compared to the original. Compressing and uncompressing content consumes a huge amount of system resources, especially CPU processing time, therefore each and every Internet hosting platform which uses compression in real time must have sufficient power to support this attribute. An example how info can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" the number of consecutive 1s or 0s there should be instead of keeping the entire code.
Data Compression in Cloud Web Hosting
The compression algorithm used by the ZFS file system that runs on our cloud internet hosting platform is known as LZ4. It can upgrade the performance of any website hosted in a cloud web hosting account with us since not only does it compress info much better than algorithms used by various file systems, but also uncompresses data at speeds that are higher than the hard disk drive reading speeds. This is achieved by using a lot of CPU processing time, which 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 allows us to create backups quicker and on reduced disk space, so we shall have several daily backups of your files and databases and their generation won't change the performance of the servers. In this way, we can always recover all the content that you may have removed by mistake.
Data Compression in Semi-dedicated Servers
Your semi-dedicated server account shall be created on a cloud platform that is run on the advanced ZFS file system. The aforementioned uses a compression algorithm called LZ4, that's far better than all other algorithms when it comes to compression ratio and speed. The gain is visible especially when data is being uncompressed and not only is LZ4 much quicker than other algorithms, but it is also quicker in uncompressing data than a system is in reading from a hard disk. That is why websites running on a platform which employs LZ4 compression perform faster as the algorithm is most efficient when it processes compressible data i.e. site content. A further advantage of using LZ4 is that the backups of the semi-dedicated accounts that we keep require a lot less space and are generated faster, which enables us to store multiple daily backups of your files and databases.
