Data compression is the decrease of the number of bits which should be saved or transmitted and this process is rather important in the web hosting field as info kept on hard disk drives is generally compressed so as to take less space. You will find various algorithms for compressing data and they have different effectiveness depending on the content. Some of them remove only the redundant bits, so that no data can be lost, while others remove unneeded bits, which leads to worse quality when the particular data is uncompressed. This method requires plenty of processing time, therefore an internet hosting server should be powerful enough in order to be able to compress and uncompress data quickly. An example how binary code could be compressed is by "remembering" that there're five consecutive 1s, for example, rather than storing all five 1s.
Data Compression in Cloud Website Hosting
The ZFS file system which is run on our cloud Internet hosting platform uses a compression algorithm identified as LZ4. The latter is significantly faster and better than any other algorithm you will find, 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 overall performance of Internet sites hosted on ZFS-based platforms. Since the algorithm compresses data very well and it does that very fast, we're able to generate several backup copies of all the content stored in the cloud website hosting
accounts on our servers every day. Both your content and its backups will require less space and since both ZFS and LZ4 work very quickly, the backup generation will not influence the performance of the web servers where your content will be kept.
Data Compression in Semi-dedicated Servers
The ZFS file system that runs on the cloud platform where your semi-dedicated server
account will be created uses a powerful compression algorithm called LZ4. It's one of the best algorithms out there and definitely the most efficient one when it comes to compressing and uncompressing web content, as its ratio is very high and it can uncompress data at a higher speed than the same data can be read from a hard drive if it were uncompressed. This way, using LZ4 will boost any website that runs on a platform where the algorithm is enabled. The high performance requires lots of CPU processing time, that is provided by the great number of clusters working together as a part of our platform. In addition, LZ4 enables us to generate several backups of your content every day and have them for one month as they will take a reduced amount of space than regular backups and will be generated much quicker without loading the servers.
