The term data compression means reducing the number of bits of data that has to be saved or transmitted. This can be achieved with or without losing info, so what will be erased throughout the compression can be either redundant data or unneeded one. When the data is uncompressed afterwards, in the first case the content and the quality will be the same, while in the second case the quality will be worse. There're various compression algorithms which are better for various type of info. Compressing and uncompressing data frequently takes a lot of processing time, therefore the server executing the action must have adequate resources in order to be able to process your info fast enough. An 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 actual 1s and 0s.
Data Compression in Shared Hosting
The compression algorithm that we use on the cloud hosting platform where your new shared hosting account will be created is named LZ4 and it's applied by the leading-edge ZFS file system which powers the platform. The algorithm is superior to the ones other file systems employ as its compression ratio is a lot higher and it processes data considerably faster. The speed is most noticeable when content is being uncompressed as this happens quicker than information can be read from a hard disk drive. Consequently, LZ4 improves the performance of each website hosted on a server that uses this algorithm. We use LZ4 in one more way - its speed and compression ratio allow us to make a couple of daily backup copies of the entire content of all accounts and store them for 30 days. Not only do the backup copies take less space, but in addition their generation does not slow the servers down like it can often happen with alternative file systems.
Data Compression in Semi-dedicated Hosting
If you host your websites in a semi-dedicated hosting account with our firm, you can experience the advantages of LZ4 - the powerful compression algorithm used by the ZFS file system that's behind our advanced cloud Internet hosting platform. What distinguishes LZ4 from all of the other algorithms out there is that it has a higher compression ratio and it is considerably faster, in particular when it comes to uncompressing web content. It does that even quicker than uncompressed information can be read from a hard drive, so your sites will perform faster. The higher speed is at the expense of using a great deal of CPU processing time, which is not an issue for our platform because it consists of numerous clusters working together. Together with the superior performance, you'll also have multiple daily backup copies at your disposal, so you'll be able to restore any deleted content with a couple of clicks. The backup copies are available for a whole month and we can afford to keep them as they need considerably less space than ordinary backups.
