Data compression is the decrease of the number of bits that have to be stored or transmitted and this particular process is very important in the internet hosting field due to the fact that info recorded on HDDs is often compressed to take less space. There are different algorithms for compressing information and they offer different efficiency based upon the content. A number of them remove just the redundant bits, so that no data will be lost, while others remove unnecessary bits, which leads to worse quality when your data is uncompressed. The method consumes a lot of processing time, which means that a hosting server needs to be powerful enough to be able to compress and uncompress data quickly. An example how binary code could be compressed is by "remembering" that there are five sequential 1s, for example, in contrast to storing all five 1s.

Data Compression in Cloud Website Hosting

The ZFS file system which runs on our cloud Internet hosting platform uses a compression algorithm named LZ4. The aforementioned is a lot faster and better than every other algorithm out there, especially for compressing and uncompressing non-binary data i.e. internet content. LZ4 even uncompresses data quicker than it is read from a hard drive, which improves the performance of sites hosted on ZFS-based platforms. Due to the fact that the algorithm compresses data quite well and it does that very quickly, we can generate several backups of all the content kept in the cloud website hosting accounts on our servers every day. Both your content and its backups will require less space and since both ZFS and LZ4 work very fast, the backup generation will not influence the performance of the servers where your content will be stored.

Data Compression in Semi-dedicated Servers

The semi-dedicated server plans which we supply are created on a powerful cloud platform that runs on the ZFS file system. ZFS uses a compression algorithm called LZ4 that is superior to 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 more quickly than it would be to read uncompressed data from a hard disk and owing to this, websites running on a platform where LZ4 is present will function quicker. We're able to benefit from this feature although it requires quite a large amount of CPU processing time because our platform uses a large number of powerful servers working together and we don't make accounts on just a single machine like a lot of companies do. There is another advantage of using LZ4 - considering the fact that it compresses data really well and does that very fast, we can also generate several daily backups of all accounts without influencing the performance of the servers and keep them for a whole month. In this way, you can always bring back any content that you delete by accident.
