The term data compression identifies reducing the number of bits of data that should be stored or transmitted. This can be achieved with or without the loss of information, so what will be erased in the course of the compression will be either redundant data or unneeded one. When the data is uncompressed later on, in the first case the information and the quality will be the same, whereas in the second case the quality shall be worse. There're various compression algorithms which are more efficient for various kind of information. Compressing and uncompressing data in most cases takes lots of processing time, which means that the server performing the action needs to have plenty of resources to be able to process your data quick enough. One simple example how information can be compressed is to store how many consecutive positions should have 1 and just how many should have 0 inside the binary code rather than 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 called LZ4. It can supercharge the performance of any Internet site hosted in a cloud hosting
account with us since not only does it compress info more effectively than algorithms employed by various other file systems, but it uncompresses data at speeds that are higher than the hard drive reading speeds. This can be done by using a lot of CPU processing time, that is not a problem for our platform owing to the fact that it uses clusters of powerful servers working together. One more advantage of LZ4 is that it allows us to create backup copies a lot faster and on reduced disk space, so we can have a couple of daily backups of your databases and files and their generation will not change the performance of the servers. This way, we can always recover all content that you may have deleted by mistake.
Data Compression in Semi-dedicated Servers
Your semi-dedicated server
account will be created on a cloud platform that runs using the advanced ZFS file system. The latter uses a compression algorithm known as LZ4, which is a lot better than other algorithms regarding compression ratio and speed. The gain is significant especially when data is being uncompressed and not only is LZ4 much quicker than other algorithms, but it is also quicker in uncompressing data than a system is in reading from a hard disk drive. Because of this websites running on a platform which employs LZ4 compression perform faster since the algorithm is most efficient when it processes compressible data i.e. website content. An additional advantage of using LZ4 is that the backups of the semi-dedicated accounts which we keep take much less space and are generated quicker, which allows us to store a couple of daily backups of your files and databases.
