The term data compression refers to lowering the number of bits of info that has to be stored or transmitted. This can be done with or without losing info, which means that what will be erased throughout the compression can be either redundant data or unneeded one. When the data is uncompressed subsequently, in the first case the information and its quality will be the same, whereas in the second case the quality will be worse. You can find various compression algorithms that are more efficient for various type of information. Compressing and uncompressing data often takes a lot of processing time, so the server executing the action must have sufficient resources to be able to process the info 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 actual 1s and 0s.
Data Compression in Website Hosting
The compression algorithm used by the ZFS file system which runs on our cloud web hosting platform is known as LZ4. It can enhance the performance of any Internet site hosted in a website hosting account with us since not only does it compress info more efficiently than algorithms employed by other file systems, but also uncompresses data at speeds that are higher than the hard disk reading speeds. This can be done by using a great deal of CPU processing time, which is not a problem for our platform because it uses clusters of powerful servers working together. A further advantage of LZ4 is that it allows us to generate backups more quickly and on lower disk space, so we shall have a couple of daily backups of your databases and files and their generation will not influence the performance of the servers. This way, we can always restore all of the content that you could have removed by accident.
Data Compression in Semi-dedicated Hosting
The semi-dedicated hosting plans which we supply are created on a powerful cloud platform which runs on the ZFS file system. ZFS uses a compression algorithm known as LZ4 that is better than any other algorithm available in terms of speed and compression ratio when it comes to processing web content. This is valid particularly when data is uncompressed because LZ4 does that quicker than it would be to read uncompressed data from a hard disk and owing to this, sites running on a platform where LZ4 is enabled will work faster. We're able to take advantage of this feature despite of the fact that it requires quite a large amount of CPU processing time as our platform uses a large number of powerful servers working together and we don't make accounts on just a single machine like the vast majority of companies do. There's an additional benefit of using LZ4 - considering the fact that it compresses data very well and does that speedily, we can also generate multiple daily backups of all accounts without affecting the performance of the servers and keep them for a month. In this way, you'll always be able to recover any content that you delete by accident.
