Data compression is the lowering of the number of bits that should be stored or transmitted and the process is really important in the internet hosting field due to the fact that info located on hard disk drives is often compressed in order to take less space. You can find various algorithms for compressing info and they offer different effectiveness depending on the content. A number of them remove only the redundant bits, so that no data will be lost, while others delete unnecessary bits, which leads to worse quality when the particular data is uncompressed. This method uses a lot of processing time, which means that an internet hosting server should be powerful enough in order to be able to compress and uncompress data right away. An example how binary code could be compressed is by "remembering" that there're five consecutive 1s, for example, as an alternative to storing all five 1s.
Data Compression in Shared Website Hosting
The cloud hosting platform where your shared website hosting
account will be made works by using the cutting-edge ZFS file system. The LZ4 compression method that the latter uses is better in various aspects, and not only does it compress data better than any compression method that similar file systems use, but it's also much quicker. The gains may be significant particularly on compressible content which includes website files. While it could sound illogical, uncompressing data with LZ4 is quicker than reading uncompressed data from a hard drive, so the performance of each and every site hosted on our servers will be improved. The better and faster compression rates also allow us to produce numerous daily backups of the full content in every single hosting account, so should you delete something by accident, the last back-up copy which we have won't be more than a couple of hours old. This is possible because the backups take significantly less space and their generation is quick enough, to not affect the performance of our servers.
Data Compression in Semi-dedicated Servers
The semi-dedicated server
plans that we provide are created on a powerful cloud platform which runs on the ZFS file system. ZFS uses a compression algorithm named LZ4 that is greater than any other algorithm you will find in terms of speed and data compression ratio when it comes to processing website content. This is valid particularly when data is uncompressed because LZ4 does that a lot faster 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 at a higher speed. We can benefit from this feature although it needs quite a large amount of CPU processing time because our platform uses many powerful servers working together and we don't make accounts on just a single machine like many companies do. There is another reward 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 month. By doing this, you'll always be able to bring back any content that you delete by mistake.
