Data compression is the reduction of the number of bits that need to be saved or transmitted and this process is very important in the internet hosting field since information stored on hard disks is often compressed to take less space. You can find different algorithms for compressing information and they offer different effectiveness depending on the content. Some of them remove only the redundant bits, so that no data can be lost, while others erase unnecessary bits, which results in worse quality once the data is uncompressed. The process consumes a lot of processing time, so an internet hosting server should be powerful enough to be able to compress and uncompress data right away. 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 Web Hosting
The ZFS file system which is run on our cloud hosting platform employs a compression algorithm called LZ4. The latter is a lot faster and better than any other algorithm on the market, particularly for compressing and uncompressing non-binary data i.e. internet content. LZ4 even uncompresses data quicker than it is read from a hard disk, which improves the overall performance of sites hosted on ZFS-based platforms. Due to the fact that the algorithm compresses data very well and it does that very quickly, we can generate several backup copies of all the content kept in the cloud web hosting accounts on our servers every day. Both your content and its backups will need reduced space and since both ZFS and LZ4 work very quickly, the backup generation will not influence the performance of the servers where your content will be kept.
Data Compression in Semi-dedicated Hosting
The semi-dedicated hosting plans that we supply are created on a powerful cloud platform which runs on the ZFS file system. ZFS uses a compression algorithm called LZ4 that surpasses any other algorithm available on the market in terms of speed and compression ratio when it comes to processing website 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 drive and for that reason, Internet sites running on a platform where LZ4 is present will function quicker. We are able to take full advantage of this feature regardless of the fact that it needs quite a lot of CPU processing time because our platform uses numerous powerful servers working together and we do not create accounts on just a single machine like many companies do. There is an additional advantage of using LZ4 - since it compresses data rather well and does that very quickly, we can also generate multiple daily backup copies of all accounts without influencing the performance of the servers and keep them for a month. In this way, you'll always be able to restore any content that you delete by accident.
