Data compression is the reduction of the number of bits which should be stored or transmitted and this process is really important in the web hosting field as information recorded on hard disk drives is typically compressed to take less space. There're different algorithms for compressing information and they provide different efficiency depending on the content. A lot of them remove just the redundant bits, so no data can be lost, while others remove unneeded bits, which results in worse quality when your data is uncompressed. The method employs a lot of processing time, therefore a hosting server needs to be powerful enough in order to be able to compress and uncompress data immediately. 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 cloud internet hosting platform where your cloud hosting account shall be generated employs the advanced ZFS file system. The LZ4 compression method that the aforementioned employs is greater in a number of aspects, and not only does it compress information better than any compression method which other file systems use, but it's also quicker. The gains are significant particularly on compressible content like website files. Although it may sound irrational, uncompressing data with LZ4 is faster than reading uncompressed data from a hard disk drive, so the performance of every website hosted on our servers will be boosted. The better and faster compression rates also make it possible for us to produce a large number of daily backups of the full content in each hosting account, so if you delete anything by accident, the last backup which we have won't be more than a couple of hours old. This is possible as the backups take considerably less space and their generation is quick enough, to not change the performance of our servers.
Data Compression in Semi-dedicated Hosting
Your semi-dedicated hosting account will be created on a cloud platform which is run on the leading-edge ZFS file system. The aforementioned uses a compression algorithm called LZ4, which is far better than all the other algorithms with regard to compression ratio and speed. The gain is visible particularly when data is being uncompressed and not only is LZ4 quicker than other algorithms, but it is also faster in uncompressing data than a system is in reading from a HDD. That is why Internet sites running on a platform which uses LZ4 compression perform better as the algorithm is most efficient when it processes compressible data i.e. site content. One more advantage of using LZ4 is that the backups of the semi-dedicated accounts which we keep need significantly less space and they are generated faster, which allows us to keep multiple daily backups of your files and databases.
