The term data compression refers to decreasing the number of bits of information which needs to be stored or transmitted. This can be done with or without losing info, so what will be erased throughout the compression can be either redundant data or unnecessary one. When the data is uncompressed later on, in the first case the information and the quality shall be identical, whereas in the second case the quality will be worse. There're different compression algorithms that are more efficient for various kind of data. Compressing and uncompressing data generally takes a lot of processing time, which means that the server carrying out the action must have adequate resources to be able to process your data quick enough. One simple example how information can be compressed is to store how many consecutive positions should have 1 and how many should have 0 inside the binary code as an alternative to storing the particular 1s and 0s.
Data Compression in Cloud Web Hosting
The compression algorithm that we use on the cloud web hosting platform where your new cloud web hosting
account will be created is known as LZ4 and it is applied by the leading-edge ZFS file system that powers the platform. The algorithm is much better than the ones other file systems employ as its compression ratio is higher and it processes data significantly quicker. The speed is most noticeable when content is being uncompressed as this happens at a faster rate than info can be read from a hard disk. Consequently, LZ4 improves the performance of every website located on a server which uses this particular algorithm. We take full advantage of LZ4 in an additional way - its speed and compression ratio let us make a couple of daily backups of the whole content of all accounts and keep them for thirty days. Not only do these backups 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
Your semi-dedicated server
account will be created on a cloud platform which is run on the cutting-edge ZFS file system. The latter uses a compression algorithm named LZ4, that is far better than alternative algorithms when it comes to compression ratio and speed. The gain is apparent particularly when data is being uncompressed and not only is LZ4 much faster than other algorithms, but it is also faster in uncompressing data than a system is in reading from a HDD. This is the reason why Internet sites running on a platform which employs LZ4 compression perform better as the algorithm is most efficient when it processes compressible data i.e. website content. Another advantage of using LZ4 is that the backup copies of the semi-dedicated accounts that we keep need a lot less space and are generated a lot faster, which allows us to have a couple of daily backups of all your files and databases.
