Data compression is the compacting of information by lowering the number of bits that are stored or transmitted. Thus, the compressed information needs considerably less disk space than the original one, so much more content could be stored using the same amount of space. There are different compression algorithms which work in different ways and with a lot of them just the redundant bits are deleted, which means that once the info is uncompressed, there is no loss of quality. Others remove unnecessary bits, but uncompressing the data later will result in reduced quality in comparison with the original. Compressing and uncompressing content requires a huge amount of system resources, and in particular CPU processing time, therefore any hosting platform which employs compression in real time needs to have adequate power to support that attribute. An example how info can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" how many consecutive 1s or 0s there should be instead of keeping the entire code.

Data Compression in Cloud Hosting

The compression algorithm which we use on the cloud hosting platform where your new cloud hosting account will be created is named LZ4 and it's used by the revolutionary ZFS file system that powers the platform. The algorithm is more advanced than the ones other file systems use since its compression ratio is a lot higher and it processes data a lot faster. The speed is most noticeable when content is being uncompressed since this happens at a faster rate than information can be read from a hard disk drive. Because of this, LZ4 improves the performance of each and every Internet site stored on a server that uses this particular algorithm. We use LZ4 in an additional way - its speed and compression ratio make it possible for us to make multiple daily backups of the whole content of all accounts and keep them for one month. Not only do these backups take less space, but their generation doesn't slow the servers down like it often happens with various other file systems.

Data Compression in Semi-dedicated Hosting

Your semi-dedicated hosting account will be created on a cloud platform that runs using the innovative ZFS file system. The aforementioned uses a compression algorithm named LZ4, which is far better than other algorithms regarding compression ratio and speed. The gain is visible especially when data is being uncompressed and not only is LZ4 faster than other algorithms, but it is also quicker in uncompressing data than a system is in reading from a hard disk drive. That is why Internet sites running on a platform which uses LZ4 compression perform better since the algorithm is most efficient when it processes compressible data i.e. website content. A further advantage of using LZ4 is that the backup copies of the semi-dedicated accounts that we keep take less space and they are generated a lot faster, which allows us to have multiple daily backups of all your files and databases.
