The term data compression refers to lowering the number of bits of info which should be stored or transmitted. This can be achieved with or without the loss of info, which means that what will be removed in the course of the compression can be either redundant data or unnecessary one. When the data is uncompressed afterwards, in the first case the data and the quality shall be the same, while in the second case the quality shall be worse. You will find various compression algorithms that are more efficient for different type of info. Compressing and uncompressing data usually takes a lot of processing time, so the server carrying out the action should have ample resources in order to be able to process the info quick enough. A simple example how information can be compressed is to store just how many sequential positions should have 1 and just how many should have 0 inside the binary code instead of storing the actual 1s and 0s.

Data Compression in Cloud Hosting

The compression algorithm used by the ZFS file system that runs on our cloud internet hosting platform is called LZ4. It can enhance the performance of any site hosted in a cloud hosting account on our end as not only does it compress data significantly better than algorithms used by alternative file systems, but also uncompresses data at speeds which are higher than the hard disk reading speeds. This is achieved by using a lot 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. An additional advantage of LZ4 is that it enables us to create backups much quicker and on less disk space, so we will have a couple of daily backups of your files and databases and their generation won't change the performance of the servers. This way, we could always recover all of the content that you could have deleted by accident.

Data Compression in Semi-dedicated Hosting

Your semi-dedicated hosting account shall be created on a cloud platform which runs on the innovative ZFS file system. The aforementioned uses a compression algorithm named LZ4, that's far better than various other algorithms in terms of compression ratio and speed. The gain is visible especially when data is being uncompressed and not only is LZ4 quicker than other algorithms, but it is also quicker in uncompressing data than a system is in reading from a hard disk. That is why websites running on a platform which employs LZ4 compression perform faster as the algorithm is most effective when it processes compressible data i.e. website content. One more advantage of using LZ4 is that the backup copies of the semi-dedicated accounts that we keep require significantly less space and they're generated a lot quicker, which allows us to keep a number of daily backups of your files and databases.
