The term data compression means lowering the number of bits of info that needs to be saved or transmitted. This can be achieved with or without losing info, which means that what will be removed during the compression will be either redundant data or unnecessary one. When the data is uncompressed subsequently, in the first case the info and the quality will be the same, while in the second case the quality shall be worse. There are different compression algorithms that are more efficient for different sort of information. Compressing and uncompressing data in most cases takes lots of processing time, therefore the server carrying out the action needs to have sufficient resources in order to be able to process your info fast enough. A simple example how information can be compressed is to store how many sequential positions should have 1 and how many should have 0 inside the binary code as an alternative to storing the particular 1s and 0s.

Data Compression in Cloud Web Hosting

The compression algorithm which we use on the cloud internet hosting platform where your new cloud web hosting account will be created is called LZ4 and it's used by the leading-edge ZFS file system which powers the system. The algorithm is better than the ones other file systems work with because its compression ratio is higher and it processes data significantly quicker. The speed is most noticeable when content is being uncompressed since this happens at a faster rate than data can be read from a hard disk. Consequently, LZ4 improves the performance of each and every Internet site stored on a server which uses this particular algorithm. We take advantage of LZ4 in an additional way - its speed and compression ratio let us make multiple daily backups of the entire content of all accounts and store them for one month. Not only do the backups take less space, but their generation doesn't slow the servers down like it can often happen with other file systems.

Data Compression in Semi-dedicated Servers

The semi-dedicated server plans which we provide are created on a powerful cloud platform that runs on the ZFS file system. ZFS employs a compression algorithm named LZ4 that surpasses any other algorithm you can find in terms of speed and data compression ratio when it comes to processing web content. This is valid particularly when data is uncompressed because LZ4 does that much faster than it would be to read uncompressed data from a hard disk drive and owing to this, sites running on a platform where LZ4 is enabled will function at a higher speed. We can benefit from the feature although it requires quite a considerable amount of CPU processing time as our platform uses a wide range of powerful servers working together and we never create accounts on just a single machine like the vast majority of companies do. There is a further reward of using LZ4 - since it compresses data really well and does that very fast, we can also make multiple daily backups of all accounts without affecting the performance of the servers and keep them for a whole month. This way, you'll always be able to recover any content that you delete by accident.
