The term data compression identifies decreasing the number of bits of info that needs to be stored or transmitted. You can do this with or without the loss of info, which means that what will be removed in the course of the compression can be either redundant data or unneeded one. When the data is uncompressed subsequently, in the first case the content and its quality will be the same, while in the second case the quality will be worse. You'll find different compression algorithms which are more effective for different sort of information. Compressing and uncompressing data frequently takes a lot of processing time, so the server executing the action needs to have ample resources in order to be able to process your info fast enough. One simple example how information can be compressed is to store just how many sequential positions should have 1 and just how many should have 0 in the binary code as an alternative to storing the particular 1s and 0s.

Data Compression in Website Hosting

The compression algorithm which we use on the cloud internet hosting platform where your new website hosting account shall be created is named LZ4 and it's applied by the leading-edge ZFS file system which powers the system. The algorithm is much better than the ones other file systems work with as its compression ratio is a lot higher and it processes data considerably faster. The speed is most noticeable when content is being uncompressed since this happens faster than information can be read from a hard disk drive. As a result, LZ4 improves the performance of each and every Internet site hosted on a server that uses this algorithm. We take full advantage of LZ4 in one more way - its speed and compression ratio let us produce multiple daily backups of the entire content of all accounts and keep them for a month. Not only do these backups take less space, but also their generation does not slow the servers down like it can often happen with alternative file systems.

Data Compression in Semi-dedicated Hosting

The semi-dedicated hosting plans that we supply are created on a powerful cloud hosting platform that runs on the ZFS file system. ZFS works with a compression algorithm known as LZ4 that outperforms any other algorithm out there in terms of speed and compression ratio when it comes to processing web content. This is valid especially when data is uncompressed since LZ4 does that a lot faster than it would be to read uncompressed data from a hard drive and owing to this, sites running on a platform where LZ4 is present will function faster. We're able to take advantage of this feature despite of the fact that it needs quite a considerable amount of CPU processing time because our platform uses a huge number of powerful servers working together and we don't make accounts on just a single machine like most companies do. There's a further advantage of using LZ4 - considering the fact that it compresses data very well and does that extremely fast, we can also make multiple daily backup copies of all accounts without affecting the performance of the servers and keep them for 30 days. That way, you will always be able to bring back any content that you delete by accident.
