Data compression is the compacting of information by decreasing the number of bits that are stored or transmitted. Because of this, the compressed data requires less disk space than the initial one, so a lot more content might be stored on identical amount of space. You'll find many different compression algorithms that work in different ways and with a number of them just the redundant bits are removed, therefore once the info is uncompressed, there's no loss of quality. Others delete excessive bits, but uncompressing the data subsequently will lead to reduced quality compared to the original. Compressing and uncompressing content requires a significant amount of system resources, and in particular CPU processing time, so each and every web hosting platform that employs compression in real time needs to have sufficient power to support this attribute. An example how info can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" what number of consecutive 1s or 0s there should be instead of keeping the entire code.

Data Compression in Cloud Hosting

The compression algorithm used by the ZFS file system which runs on our cloud hosting platform is known as LZ4. It can enhance the performance of any website hosted in a cloud hosting account with us because not only does it compress data more efficiently than algorithms used by various file systems, but it also uncompresses data at speeds that are higher than the hard disk drive reading speeds. This is achieved 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. One more advantage of LZ4 is that it enables us to generate backups much quicker and on lower disk space, so we can have a couple of daily backups of your files and databases and their generation will not affect the performance of the servers. In this way, we could always restore any content that you could have removed by accident.
