Data compression is the compacting of data by decreasing the number of bits that are stored or transmitted. Because of this, the compressed info will require considerably less disk space than the original one, so a lot more content could be stored using identical amount of space. You will find different compression algorithms that work in different ways and with a number of them only the redundant bits are removed, so once the information is uncompressed, there is no decrease in quality. Others remove unnecessary bits, but uncompressing the data subsequently 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, therefore every web hosting platform that uses compression in real time needs to have ample power to support this attribute. An example how information can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" what number of sequential 1s or 0s there should be instead of storing the actual code.
Data Compression in Cloud Web Hosting
The compression algorithm used by the ZFS file system which runs on our cloud web hosting platform is known as LZ4. It can enhance the performance of any site hosted in a cloud web hosting account with us as not only does it compress data much better than algorithms used by other file systems, but it also uncompresses data at speeds which are higher than the hard drive reading speeds. This is achieved by using a lot of CPU processing time, that is not a problem for our platform since it uses clusters of powerful servers working together. One more advantage of LZ4 is that it allows us to generate backup copies faster and on reduced disk space, so we shall have several daily backups of your files and databases and their generation won't change the performance of the servers. In this way, we can always restore any kind of content that you could have erased by accident.
