Data compression is the compacting of info by reducing the number of bits that are stored or transmitted. In this way, the compressed data takes substantially less disk space than the initial one, so a lot more content might be stored on identical amount of space. You will find different compression algorithms that work in different ways and with some of them only the redundant bits are erased, which means that once the data is uncompressed, there is no loss of quality. Others remove unneeded bits, but uncompressing the data at a later time will result in reduced quality in comparison with the original. Compressing and uncompressing content consumes a huge amount of system resources, especially CPU processing time, so any Internet hosting platform that uses compression in real time needs to have ample power to support this attribute. An example how data 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 saving the actual code.
Data Compression in Shared Web Hosting
The cloud web hosting platform where your shared web hosting
account shall be made works by using the cutting-edge ZFS file system. The LZ4 compression method which the aforementioned uses is superior in various aspects, and not only does it compress info better than any compression method which many other file systems use, but it is also faster. The benefits may be significant particularly on compressible content which includes website files. Even though it could sound irrational, uncompressing data with LZ4 is faster than reading uncompressed info from a hard disk drive, so the performance of each and every website hosted on our servers shall be upgraded. The better and quicker compression rates also make it possible for us to make numerous daily backups of the entire content in each and every Internet hosting account, so if you delete something by accident, the last back-up copy that we have won't be more than a couple of hours old. This can be done because the backups take much less space and their generation is quick enough, to not change the performance of our servers.
