Data compression is the compacting of info by lowering the number of bits which are stored or transmitted. As a result, the compressed info needs less disk space than the initial one, so more content might be stored using the same amount of space. There're different compression algorithms which function in different ways and with a lot of them just the redundant bits are deleted, which means that once the data is uncompressed, there is no loss of quality. Others erase unneeded bits, but uncompressing the data later on will lead to reduced quality compared to the original. Compressing and uncompressing content consumes a large amount of system resources, in particular CPU processing time, therefore each and every hosting platform that uses compression in real time needs to have enough power to support this attribute. An example how data can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" how many consecutive 1s or 0s there should be instead of storing the actual code.
Data Compression in Cloud Web Hosting
The compression algorithm which we work with on the cloud web hosting platform where your new cloud web hosting account will be created is known as LZ4 and it's applied by the exceptional ZFS file system which powers the system. The algorithm is greater than the ones other file systems use since its compression ratio is a lot higher and it processes data considerably quicker. The speed is most noticeable when content is being uncompressed since this happens more quickly than info can be read from a hard disk drive. Because of this, LZ4 improves the performance of each website hosted on a server that uses the algorithm. We use LZ4 in one more way - its speed and compression ratio make it possible for us to produce multiple daily backups of the whole content of all accounts and store them for one month. Not only do the backup copies take less space, but their generation won't slow the servers down like it can often happen with many other file systems.
