The term data compression means decreasing the number of bits of data which has to be stored or transmitted. This can be done with or without the loss of data, so what will be erased throughout the compression will be either redundant data or unneeded one. When the data is uncompressed later on, in the first case the data and the quality will be the same, while in the second case the quality shall be worse. You will find different compression algorithms that are more efficient for different sort of data. Compressing and uncompressing data often takes a lot of processing time, which means that the server performing the action should have plenty of resources in order to be able to process the data quick enough. A simple example how information can be compressed is to store just how many sequential positions should have 1 and how many should have 0 in the binary code rather than storing the particular 1s and 0s.
Data Compression in Cloud Web Hosting
The compression algorithm that we work with on the cloud internet hosting platform where your new cloud web hosting
account shall be created is called LZ4 and it's applied by the advanced ZFS file system which powers the system. The algorithm is superior to the ones other file systems use since its compression ratio is higher and it processes data significantly faster. The speed is most noticeable when content is being uncompressed since this happens even faster than information can be read from a hard disk. Consequently, LZ4 improves the performance of each and every Internet 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 several daily backup copies of the full content of all accounts and store them for thirty days. Not only do the backup copies take less space, but also their generation does not slow the servers down like it can often happen with some other file systems.
Data Compression in Semi-dedicated Servers
In case you host your Internet sites in a semi-dedicated server
account from our company, you can experience the advantages of LZ4 - the powerful compression algorithm used by the ZFS file system that's behind our advanced cloud hosting platform. What differentiates LZ4 from all the other algorithms out there is that it has a higher compression ratio and it is much quicker, 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 better. The higher speed comes at the expense of using a lot of CPU processing time, which is not a problem for our platform because it consists of numerous clusters working together. Besides the superior performance, you'll have multiple daily backup copies at your disposal, so you will be able to restore any deleted content with just a few clicks. The backup copies are available for a whole month and we can afford to store them as they need considerably less space than standard backups.
