Data compression is the lowering of the number of bits which need to be stored or transmitted and the process is very important in the web hosting field as data filed on hard disk drives is often compressed in order to take less space. There are different algorithms for compressing info and they offer different effectiveness depending on the content. Some of them remove just the redundant bits, so no data can be lost, while others remove unnecessary bits, which leads to worse quality once your data is uncompressed. This method employs a lot of processing time, therefore a hosting server needs to be powerful enough to be able to compress and uncompress data instantly. An illustration how binary code could be compressed is by "remembering" that there're 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 identified as LZ4. The aforementioned is substantially faster and better than every other algorithm on the market, 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 websites 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 backup copies of all the content stored in the cloud website hosting
accounts on our servers on a daily basis. Both your content and its backups will require less space and since both ZFS and LZ4 work extremely fast, the backup generation will not change the performance of the 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 that runs using the innovative ZFS file system. The latter uses a compression algorithm known as LZ4, that is significantly better than various other algorithms with regard to compression ratio and speed. The gain is significant especially 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 websites running on a platform that employs LZ4 compression perform faster since the algorithm is most effective when it processes compressible data i.e. site content. One more advantage of using LZ4 is that the backup copies of the semi-dedicated accounts that we keep require less space and are generated a lot quicker, which enables us to keep several daily backups of all your files and databases.
