Data compression is the compacting of info by reducing the number of bits which are stored or transmitted. Consequently, the compressed data will take substantially less disk space than the original one, so much more content can be stored using identical amount of space. You will find many different compression algorithms that function in different ways and with several of them only the redundant bits are deleted, so once the information is uncompressed, there's no decrease in quality. Others delete unneeded bits, but uncompressing the data following that will result in reduced quality in comparison with the original. Compressing and uncompressing content needs a large amount of system resources, especially CPU processing time, so any Internet hosting platform that employs compression in real time needs to have enough power to support that attribute. An example how info 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 entire code.
Data Compression in Cloud Web Hosting
The compression algorithm used by the ZFS file system that runs on our cloud hosting platform is called LZ4. It can boost the performance of any site hosted in a cloud web hosting account with us because not only does it compress data more effectively than algorithms used by various file systems, but also uncompresses data at speeds that are higher than the hard disk drive reading speeds. This can be done by using a great deal of CPU processing time, which is not a problem for our platform considering the fact that it uses clusters of powerful servers working together. An additional advantage of LZ4 is that it enables us to generate backup copies more speedily and on reduced disk space, so we can have multiple daily backups of your databases and files and their generation won't influence the performance of the servers. This way, we can always recover any content that you could have deleted by mistake.
