Data compression is the lowering of the number of bits which need to be stored or transmitted and this process is really important in the internet hosting field due to the fact that information located on HDDs is usually compressed in order to take less space. You can find many different algorithms for compressing info and they offer different efficiency based upon the content. A number of them remove only the redundant bits, so that no data will be lost, while others remove unnecessary bits, which results in worse quality once the particular data is uncompressed. The process consumes plenty of processing time, which means that a web hosting server has to be powerful enough to be able to compress and uncompress data in real time. An illustration how binary code could be compressed is by "remembering" that there're five sequential 1s, for example, rather than storing all five 1s.

Data Compression in Web Hosting

The compression algorithm used by the ZFS file system that runs on our cloud internet hosting platform is known as LZ4. It can improve the performance of any website hosted in a web hosting account on our end because not only does it compress data much better than algorithms used by various other file systems, but also uncompresses data at speeds that are higher than the hard drive reading speeds. This is achieved by using a great deal of CPU processing time, that is not a problem for our platform owing to the fact that it uses clusters of powerful servers working together. An additional advantage of LZ4 is that it enables us to create backup copies much quicker and on lower disk space, so we shall have a couple of daily backups of your files and databases and their generation will not change the performance of the servers. This way, we can always restore all of the content that you could have deleted by accident.

Data Compression in Semi-dedicated Hosting

The semi-dedicated hosting plans that we supply are created on a powerful cloud hosting platform which runs on the ZFS file system. ZFS uses a compression algorithm known as LZ4 that is better than any other algorithm you will find in terms of speed and data compression ratio when it comes to processing web content. This is valid especially when data is uncompressed because LZ4 does that much faster than it would be to read uncompressed data from a hard drive and as a result, sites running on a platform where LZ4 is present will work at a higher speed. We're able to take full advantage of the feature although it requires quite a large amount of CPU processing time because our platform uses a number of powerful servers working together and we don't create accounts on just a single machine like the vast majority of companies do. There is another advantage of using LZ4 - considering that it compresses data very well and does that very quickly, we can also generate multiple daily backups of all accounts without influencing the performance of the servers and keep them for an entire month. By doing this, you can always recover any content that you erase by mistake.
