Data compression is the compacting of information by lowering the number of bits that are stored or transmitted. This way, the compressed info requires much less disk space than the original one, so much more content could 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 erased, therefore once the data is uncompressed, there is no decrease in quality. Others delete unneeded bits, but uncompressing the data at a later time will lead to reduced quality in comparison with the original. Compressing and uncompressing content consumes a significant amount of system resources, especially CPU processing time, so each and every Internet hosting platform that employs compression in real time needs to have sufficient power to support this feature. An example how info can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" what number of sequential 1s or 0s there should be instead of keeping the whole code.
Data Compression in Cloud Website Hosting
The compression algorithm used by the ZFS file system which runs on our cloud internet hosting platform is named LZ4. It can enhance the performance of any Internet site hosted in a cloud website hosting account on our end as not only does it compress info much better than algorithms employed by various file systems, but it uncompresses data at speeds that are higher than the HDD reading speeds. This is achieved by using a great deal of CPU processing time, which is not a problem for our platform due to the fact that it uses clusters of powerful servers working together. A further advantage of LZ4 is that it enables us to create backup copies faster and on less disk space, so we shall have a couple of daily backups of your files and databases and their generation will not influence the performance of the servers. In this way, we can always recover all content that you may have erased by accident.
