Data compression is the decrease of the number of bits which need to be saved or transmitted and this process is really important in the internet hosting field since information filed on HDDs is usually compressed so as to take less space. You can find many different algorithms for compressing info and they have different efficiency depending on the content. A lot of them remove only the redundant bits, so no data will be lost, while others delete unneeded bits, which leads to worse quality when the particular data is uncompressed. The process needs plenty of processing time, therefore a hosting server has to be powerful enough to be able to compress and uncompress data instantly. One example how binary code could be compressed is by "remembering" that there're five sequential 1s, for example, as an alternative to storing all five 1s.

Data Compression in Cloud Hosting

The ZFS file system that runs on our cloud web hosting platform uses a compression algorithm identified as LZ4. The latter is substantially faster and better than every other algorithm you'll find, especially for compressing and uncompressing non-binary data i.e. internet content. LZ4 even uncompresses data faster than it is read from a hard disk, which improves the performance of websites hosted on ZFS-based platforms. Since the algorithm compresses data quite well and it does that very quickly, we are able to generate several backups of all the content kept in the cloud hosting accounts on our servers on a daily basis. Both your content and its backups will need reduced space and since both ZFS and LZ4 work extremely fast, the backup generation will not change the performance of the servers where your content will be kept.

Data Compression in Semi-dedicated Hosting

The semi-dedicated hosting plans that we offer are created on a powerful cloud hosting platform which runs on the ZFS file system. ZFS employs a compression algorithm named LZ4 that exceeds any other algorithm on the market in terms of speed and compression ratio when it comes to processing web content. This is valid particularly when data is uncompressed as LZ4 does that quicker than it would be to read uncompressed data from a hard disk and because of this, Internet sites running on a platform where LZ4 is enabled will work at a higher speed. We can benefit from this feature regardless of the fact that it requires quite a great deal of CPU processing time as our platform uses a lot of powerful servers working together and we do not create accounts on just a single machine like a lot of companies do. There's another advantage of using LZ4 - considering that it compresses data really well and does that extremely fast, we can also make several daily backups of all accounts without affecting the performance of the servers and keep them for an entire month. That way, you will always be able to bring back any content that you erase by accident.
