Data compression is the reduction of the number of bits that need to be saved or transmitted and the process is very important in the internet hosting field due to the fact that information stored on hard disk drives is generally compressed to take less space. There are different algorithms for compressing data and they have different efficiency depending on the content. A lot of them remove just the redundant bits, so that no data will be lost, while others remove unneeded bits, which leads to worse quality when the particular data is uncompressed. This process employs plenty of processing time, therefore an internet hosting server has to be powerful enough to be able to compress and uncompress data immediately. An example how binary code can 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 Web Hosting
The compression algorithm used by the ZFS file system which runs on our cloud web hosting platform is named LZ4. It can enhance the performance of any website hosted in a cloud web hosting account with us since not only does it compress info more efficiently than algorithms used by various other file systems, but it also uncompresses data at speeds which are higher than the HDD reading speeds. This is achieved by using a great deal of CPU processing time, which is not a problem for our platform for the reason that it uses clusters of powerful servers working together. A further advantage of LZ4 is that it enables us to generate backup copies faster and on reduced disk space, so we shall have multiple daily backups of your databases and files and their generation won't change the performance of the servers. In this way, we could always recover all content that you may have erased by accident.
Data Compression in Semi-dedicated Servers
Your semi-dedicated server account shall be created on a cloud platform that runs on the advanced ZFS file system. The latter uses a compression algorithm called LZ4, that's significantly better than other algorithms with regard to compression ratio and speed. The gain is significant particularly when data is being uncompressed and not only is LZ4 much faster than other algorithms, but it is also quicker in uncompressing data than a system is in reading from a hard drive. This is the reason why sites running on a platform that employs LZ4 compression perform faster because the algorithm is most efficient when it processes compressible data i.e. web content. Another advantage of using LZ4 is that the backups of the semi-dedicated accounts which we keep require much less space and they're generated a lot quicker, which allows us to have a number of daily backups of your files and databases.
