The term data compression means lowering the number of bits of data which should be saved or transmitted. This can be done with or without the loss of information, which means that what will be deleted in the course of the compression will be either redundant data or unneeded one. When the data is uncompressed subsequently, in the first case the content and its quality will be the same, while in the second case the quality shall be worse. You will find different compression algorithms which are more effective for different sort of info. Compressing and uncompressing data normally takes a lot of processing time, so the server executing the action must have sufficient resources to be able to process the data quick enough. A simple example how information can be compressed is to store how many sequential positions should have 1 and how many should have 0 inside the binary code instead of storing the particular 1s and 0s.
Data Compression in Cloud Hosting
The cloud hosting platform where your cloud hosting
account shall be made works by using the advanced ZFS file system. The LZ4 compression method that the latter uses is better in a number of aspects, and not only does it compress information better than any compression method which some other file systems use, but it's also a lot quicker. The gains may be significant in particular on compressible content such as website files. Even though it could sound irrational, uncompressing data with LZ4 is faster than reading uncompressed info from a hard disk, so the performance of each site hosted on our servers shall be better. The better and faster compression rates also allow us to produce multiple daily backups of the entire content in each web hosting account, so in the event you delete anything by mistake, the last back-up copy that we have will not be more than a couple of hours old. This can be done because the backups take significantly less space and their generation is quick enough, so as to not change the performance of our servers.
