The term data compression identifies decreasing the number of bits of data which needs to be saved or transmitted. You can do this with or without losing information, which means that what will be removed at the time of the compression will be either redundant data or unnecessary one. When the data is uncompressed later on, in the first case the information and the quality shall be identical, while in the second case the quality shall be worse. You'll find various compression algorithms which are better for different sort of information. Compressing and uncompressing data generally takes lots of processing time, therefore the server performing the action needs to have ample resources to be able to process the 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 as an alternative to storing the actual 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 known as LZ4. It can enhance the performance of any site hosted in a cloud web hosting account on our end because not only does it compress data much better than algorithms employed by alternative file systems, but it also uncompresses data at speeds which are higher than the HDD reading speeds. This can be done by using a lot of CPU processing time, which is not a problem for our platform considering that it uses clusters of powerful servers working together. An additional advantage of LZ4 is that it allows us to create backup copies at a higher speed and on less disk space, so we shall have multiple daily backups of your files and databases and their generation won't influence the performance of the servers. This way, we could always recover all content that you could have deleted by mistake.

Data Compression in Semi-dedicated Servers

The semi-dedicated server plans which we offer are created on a powerful cloud hosting platform that runs on the ZFS file system. ZFS employs a compression algorithm named LZ4 that is superior to any other algorithm on the market in terms of speed and compression ratio when it comes to processing web content. This is valid especially when data is uncompressed because LZ4 does that more rapidly than it would be to read uncompressed data from a hard disk and because of this, websites running on a platform where LZ4 is present will function at a higher speed. We can take full advantage of this feature despite of the fact that it needs quite a considerable amount of CPU processing time as our platform uses numerous powerful servers working together and we do not create accounts on just a single machine like most companies do. There is another reward of using LZ4 - given that it compresses data rather well and does that very quickly, we can also generate several daily backups of all accounts without influencing the performance of the servers and keep them for an entire month. In this way, you can always bring back any content that you delete by mistake.
