The term data compression refers to lowering the number of bits of info which has to be stored or transmitted. You can do this with or without the loss of information, which means that what will be deleted throughout the compression will be either redundant data or unneeded one. When the data is uncompressed afterwards, in the first case the content and the quality shall be the same, whereas in the second case the quality will be worse. There are different compression algorithms which are better for different type of info. Compressing and uncompressing data frequently takes lots of processing time, so the server executing the action should have plenty of resources to be able to process your data quick enough. A simple example how information can be compressed is to store how many consecutive positions should have 1 and how many should have 0 within the binary code instead of storing the particular 1s and 0s.
Data Compression in Cloud Web Hosting
The compression algorithm employed by the ZFS file system that runs on our cloud web hosting platform is called LZ4. It can improve the performance of any website hosted in a cloud web hosting account with us because not only does it compress data more effectively than algorithms used by various file systems, but also uncompresses data at speeds that are higher than the hard disk drive reading speeds. This is achieved by using a lot of CPU processing time, that is not a problem for our platform for the reason that it uses clusters of powerful servers working together. An additional advantage of LZ4 is that it allows us to make backup copies faster and on reduced disk space, so we will have a couple of daily backups of your databases and files and their generation won't affect the performance of the servers. In this way, we can always restore all the content that you may have erased by mistake.
Data Compression in Semi-dedicated Hosting
If you host your websites in a semi-dedicated hosting account with our firm, you will be able to experience the advantages of LZ4 - the powerful compression algorithm used by the ZFS file system that's behind our advanced cloud hosting platform. What distinguishes LZ4 from all other algorithms out there is that it has a better compression ratio and it is much quicker, in particular when it comes to uncompressing web content. It does that even faster than uncompressed data can be read from a hard drive, so your websites will perform faster. The higher speed comes at the expense of using a great deal of CPU processing time, which is not an issue for our platform since it consists of a large number of clusters working together. In addition to the improved performance, you'll also have multiple daily backups at your disposal, so you can restore any deleted content with a few clicks. The backups are available for an entire month and we can afford to keep them as they need significantly less space compared to ordinary backups.
