Data compression is the decrease of the number of bits that should be saved or transmitted and the process is rather important in the internet hosting field as information filed on hard disk drives is typically compressed in order to take less space. There're different algorithms for compressing data and they offer different efficiency based on the content. A number of them remove just the redundant bits, so no data can be lost, while others erase unneeded bits, which leads to worse quality once your data is uncompressed. The process needs a lot of processing time, so a web hosting server has to be powerful enough to be able to compress and uncompress data in real time. An illustration how binary code can be compressed is by "remembering" that there are five consecutive 1s, for example, in contrast to storing all five 1s.
Data Compression in Cloud Website Hosting
The compression algorithm which we use on the cloud web hosting platform where your new cloud website hosting
account will be created is named LZ4 and it is applied by the revolutionary ZFS file system which powers the system. The algorithm is superior to the ones other file systems employ because its compression ratio is a lot higher and it processes data significantly faster. The speed is most noticeable when content is being uncompressed as this happens at a faster rate than info can be read from a hdd. As a result, LZ4 improves the performance of each website located on a server which uses the algorithm. We take full advantage of LZ4 in an additional way - its speed and compression ratio allow us to make a couple of daily backups of the whole content of all accounts and keep them for 30 days. Not only do the backups take less space, but their generation will not slow the servers down like it often happens with various other file systems.
Data Compression in Semi-dedicated Servers
Your semi-dedicated server
account will be created on a cloud platform which runs using the advanced ZFS file system. The aforementioned uses a compression algorithm called 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 quicker than other algorithms, but it is also quicker in uncompressing data than a system is in reading from a hard disk drive. This is why sites running on a platform that employs 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 take a lot less space and they're generated a lot quicker, which enables us to have several daily backups of all your files and databases.
