The term data compression identifies reducing the number of bits of info which has to be saved or transmitted. This can be done with or without the loss of information, which means that what will be removed in the course of the compression will be either redundant data or unneeded one. When the data is uncompressed afterwards, in the first case the content and the quality shall be the same, whereas in the second case the quality will be worse. There're different compression algorithms which are more effective for different sort of data. Compressing and uncompressing data often takes lots of processing time, therefore the server carrying out the action must have plenty of resources in order to be able to process the info fast enough. An example how information can be compressed is to store just how many sequential positions should have 1 and just how many should have 0 in the binary code as an alternative to storing the actual 1s and 0s.
Data Compression in Cloud Hosting
The compression algorithm that we employ on the cloud hosting platform where your new cloud hosting account will be created is named LZ4 and it is applied by the cutting-edge ZFS file system that powers the platform. The algorithm is better than the ones other file systems employ because 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 hdd. Consequently, LZ4 improves the performance of every site stored on a server that uses the algorithm. We use LZ4 in one more way - its speed and compression ratio make it possible for us to generate a number of daily backups of the entire content of all accounts and store them for a month. Not only do our backup copies take less space, but in addition their generation doesn't slow the servers down like it often happens with various other file systems.
