The term data compression identifies reducing the number of bits of information that has to be stored or transmitted. You can do this with or without the loss of info, which means that what will be deleted during the compression will be either redundant data or unneeded one. When the data is uncompressed afterwards, in the first case the data and the quality will be identical, while in the second case the quality will be worse. You'll find different compression algorithms which are more efficient for different sort of data. Compressing and uncompressing data generally takes lots of processing time, so the server executing the action needs to have enough resources to be able to process the data fast enough. One simple example how information can be compressed is to store just how many sequential positions should have 1 and how many should have 0 inside the binary code as an alternative to storing the particular 1s and 0s.
Data Compression in Cloud Website Hosting
The compression algorithm employed by the ZFS file system which runs on our cloud hosting platform is named LZ4. It can upgrade the performance of any site hosted in a cloud website hosting account with us as not only does it compress data significantly better than algorithms employed by other file systems, but it also uncompresses data at speeds that are higher than the hard drive reading speeds. This is achieved by using a lot of CPU processing time, that is not a problem for our platform since it uses clusters of powerful servers working together. A further advantage of LZ4 is that it enables us to generate backup copies more speedily and on reduced disk space, so we will have a couple of daily backups of your files and databases and their generation will not influence the performance of the servers. In this way, we can always recover the content that you may have deleted by accident.
Data Compression in Semi-dedicated Servers
Your semi-dedicated server account will be created on a cloud platform which runs on the cutting-edge ZFS file system. The latter uses a compression algorithm called LZ4, that's much better than all the other algorithms in terms of compression ratio and speed. The gain is noticeable especially when data is being uncompressed and not only is LZ4 faster than other algorithms, but it is also faster in uncompressing data than a system is in reading from a hard disk drive. That's why Internet sites running on a platform that uses LZ4 compression perform better since the algorithm is most effective when it processes compressible data i.e. web content. One more advantage of using LZ4 is that the backup copies of the semi-dedicated accounts that we keep take less space and are generated a lot faster, which allows us to store several daily backups of all your files and databases.
