Data compression is the compacting of data by reducing the number of bits which are stored or transmitted. As a result, the compressed info will need less disk space than the initial one, so a lot more content might be stored on the same amount of space. You will find different compression algorithms which function in different ways and with a number of them just the redundant bits are removed, so once the information is uncompressed, there's no loss of quality. Others remove unnecessary bits, but uncompressing the data at a later time will lead to reduced quality compared to the original. Compressing and uncompressing content needs a large amount of system resources, and in particular CPU processing time, so every hosting platform that uses compression in real time needs to have adequate power to support that feature. An example how information can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" the number of sequential 1s or 0s there should be instead of storing the whole code.
Data Compression in Cloud Hosting
The cloud hosting platform where your cloud hosting
account is generated works by using the impressive ZFS file system. The LZ4 compression method which the latter employs is greater in numerous aspects, and not only does it compress data better than any compression method which some other file systems use, but it's also much quicker. The benefits are significant especially on compressible content which includes website files. While it could sound irrational, uncompressing data with LZ4 is quicker than reading uncompressed info from a hard drive, so the performance of each site hosted on our servers shall be enhanced. The better and quicker compression rates also allow us to produce a large number of daily backups of the entire content in each hosting account, so if you delete something by accident, the last backup which we have will not be more than a couple of hours old. This is possible because the backups take a lot less space and their generation is fast enough, so as to not change the performance of the servers.
