The term data compression means decreasing the number of bits of information that needs to be stored or transmitted. This can be done with or without the loss of info, so what will be deleted throughout the compression can be either redundant data or unnecessary one. When the data is uncompressed afterwards, in the first case the information and the quality shall be identical, whereas in the second case the quality will be worse. There're different compression algorithms which are more effective for different sort of information. Compressing and uncompressing data normally takes lots of processing time, which means that the server carrying out the action needs to have enough resources in order to be able to process the info fast enough. An example how information can be compressed is to store just how many sequential positions should have 1 and just how many should have 0 within the binary code as an alternative to storing the actual 1s and 0s.
Data Compression in Cloud Hosting
The compression algorithm used by the ZFS file system that runs on our cloud internet hosting platform is known as LZ4. It can enhance the performance of any website hosted in a cloud hosting account on our end because not only does it compress info more efficiently than algorithms used by alternative file systems, but it uncompresses data at speeds that are higher than the HDD reading speeds. This is achieved by using a lot of CPU processing time, which 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 make backups a lot faster and on less disk space, so we shall have several daily backups of your databases and files and their generation won't change the performance of the servers. In this way, we could always recover all the content that you could have erased by mistake.
Data Compression in Semi-dedicated Hosting
If you host your Internet sites in a semi-dedicated hosting account with our company, you will be able to experience the advantages of LZ4 - the powerful compression algorithm employed by the ZFS file system that's behind our advanced cloud web hosting platform. What separates LZ4 from all of the other algorithms out there is that it has a better 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 disk drive, so your sites will perform faster. The higher speed is at the expense of using a lot of CPU processing time, that is not a problem for our platform as it consists of a lot of clusters working together. In addition to the better performance, you'll have multiple daily backups at your disposal, so you will be able to recover any deleted content with several clicks. The backups are available for a whole month and we can afford to keep them since they need significantly less space compared to standard backups.
