The term data compression refers to reducing the number of bits of data which has to be stored or transmitted. This can be done with or without losing information, so what will be deleted in the course of the compression can be either redundant data or unneeded one. When the data is uncompressed afterwards, in the first case the information and the quality will be the same, while in the second case the quality shall be worse. You'll find different compression algorithms which are more effective for different sort of data. Compressing and uncompressing data often takes lots of processing time, which means that the server carrying out the action must have sufficient resources in order to be able to process your info fast enough. One simple example how information can be compressed is to store just how many consecutive positions should have 1 and just how many should have 0 in the binary code as an alternative to storing the particular 1s and 0s.
Data Compression in Cloud Hosting
The compression algorithm that we work with on the cloud internet hosting platform where your new cloud hosting
account shall be created is known as LZ4 and it's applied by the exceptional ZFS file system that powers the platform. The algorithm is more advanced than the ones other file systems employ because its compression ratio is a lot higher and it processes data significantly quicker. The speed is most noticeable when content is being uncompressed since this happens more quickly than data can be read from a hard drive. As a result, LZ4 improves the performance of each Internet site located on a server that uses this algorithm. We take full advantage of LZ4 in one more way - its speed and compression ratio allow us to produce multiple daily backup copies of the full content of all accounts and store them for thirty days. Not only do our backup copies take less space, but 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 shall be created on a cloud platform that runs using the advanced ZFS file system. The latter uses a compression algorithm known as LZ4, that is a lot better than alternative algorithms in terms of compression ratio and speed. The gain is apparent especially when data is being uncompressed and not only is LZ4 a lot faster than other algorithms, but it is also quicker in uncompressing data than a system is in reading from a hard disk. This is the reason why Internet sites running on a platform which uses LZ4 compression perform faster because the algorithm is most efficient when it processes compressible data i.e. website content. An additional advantage of using LZ4 is that the backups of the semi-dedicated accounts that we keep need less space and are generated a lot faster, which allows us to have multiple daily backups of your files and databases.
