Data compression is the reduction of the number of bits that should be stored or transmitted and the process is rather important in the internet hosting field because information located on hard drives is usually compressed to take less space. You'll find different algorithms for compressing data and they offer different efficiency depending on the content. Many of them remove only the redundant bits, so no data will be lost, while others delete unnecessary bits, which results in worse quality when the data is uncompressed. This method uses a lot of processing time, which means that an internet hosting server needs to be powerful enough in order to be able to compress and uncompress data in real time. One example how binary code may be compressed is by "remembering" that there are five sequential 1s, for example, as an alternative to storing all five 1s.
Data Compression in Cloud Hosting
The ZFS file system which runs on our cloud web hosting platform employs a compression algorithm called LZ4. The latter is considerably faster and better than any other algorithm you'll find, particularly for compressing and uncompressing non-binary data i.e. web content. LZ4 even uncompresses data faster than it is read from a hard disk drive, which improves the performance of websites hosted on ZFS-based platforms. Since the algorithm compresses data really well and it does that very quickly, we're able to generate several backup copies of all the content kept in the cloud hosting accounts on our servers on a daily basis. Both your content and its backups will take reduced space and since both ZFS and LZ4 work very fast, the backup generation will not influence the performance of the web hosting servers where your content will be stored.
Data Compression in Semi-dedicated Servers
Your semi-dedicated server account will be created on a cloud platform which is run on the advanced ZFS file system. The aforementioned uses a compression algorithm named LZ4, which is significantly better than all the other algorithms with regard to compression ratio and speed. The gain is apparent especially when data is being uncompressed and not only is LZ4 much faster than other algorithms, but it is also faster in uncompressing data than a system is in reading from a hard disk drive. That's why sites running on a platform which uses LZ4 compression perform faster because the algorithm is most effective when it processes compressible data i.e. site content. A further advantage of using LZ4 is that the backups of the semi-dedicated accounts which we keep take much less space and they're generated a lot quicker, which allows us to store multiple daily backups of your files and databases.
