The term data compression identifies reducing the number of bits of information that needs to be saved or transmitted. This can be achieved with or without the loss of information, so what will be removed during the compression can be either redundant data or unnecessary one. When the data is uncompressed subsequently, in the first case the content and the quality shall be the same, whereas in the second case the quality shall be worse. You'll find various compression algorithms that are more effective for different kind of data. Compressing and uncompressing data frequently takes a lot of processing time, therefore the server performing the action should have adequate resources in order to be able to process the info quick enough. A simple example how information can be compressed is to store how many consecutive positions should have 1 and just how many should have 0 within the binary code instead of storing the actual 1s and 0s.

Data Compression in Cloud 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 hosting account on our end since not only does it compress info much better than algorithms employed by alternative file systems, but also uncompresses data at speeds that are higher than the hard drive reading speeds. This can be done by using a great deal of CPU processing time, which is not a problem for our platform considering the fact that it uses clusters of powerful servers working together. A further advantage of LZ4 is that it enables us to generate backup copies more quickly and on less disk space, so we will have several daily backups of your databases and files and their generation will not affect the performance of the servers. This way, we could always restore any content that you could have deleted by accident.

Data Compression in Semi-dedicated Servers

Your semi-dedicated server account shall be created on a cloud platform that runs on the innovative ZFS file system. The aforementioned uses a compression algorithm named LZ4, that's far better than alternative algorithms regarding compression ratio and speed. The gain is visible particularly when data is being uncompressed and not only is LZ4 quicker than other algorithms, but it is also faster in uncompressing data than a system is in reading from a hard disk drive. That is why sites running on a platform which employs LZ4 compression perform better since the algorithm is most efficient when it processes compressible data i.e. web content. Another advantage of using LZ4 is that the backup copies of the semi-dedicated accounts which we keep take significantly less space and they're generated faster, which allows us to keep multiple daily backups of your files and databases.
