The term data compression identifies decreasing the number of bits of info which should be stored or transmitted. This can be achieved with or without the loss of info, so what will be removed during the compression can be either redundant data or unneeded one. When the data is uncompressed afterwards, in the first case the info and its quality will be identical, whereas in the second case the quality shall be worse. There're various compression algorithms which are more effective for different type of information. Compressing and uncompressing data in most cases takes plenty of processing time, which means that the server carrying out the action needs to have enough resources to be able to process your data fast enough. One simple example how information can be compressed is to store how many consecutive positions should have 1 and how many should have 0 in the binary code as an alternative to storing the particular 1s and 0s.

Data Compression in Cloud Hosting

The compression algorithm which we use on the cloud web hosting platform where your new cloud hosting account will be created is known as LZ4 and it's used by the advanced ZFS file system which powers the platform. The algorithm is much better than the ones other file systems work with since its compression ratio is higher and it processes data a lot quicker. The speed is most noticeable when content is being uncompressed since this happens even faster than information can be read from a hdd. Because of this, LZ4 improves the performance of each and every Internet site hosted 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 a number of daily backup copies of the full content of all accounts and store them for 30 days. Not only do these backup copies take less space, but also their generation won't slow the servers down like it often happens with other file systems.

Data Compression in Semi-dedicated Hosting

The ZFS file system that runs on the cloud platform where your semi-dedicated hosting account will be created uses a powerful compression algorithm called LZ4. It's among the best algorithms out there and certainly the most efficient one when it comes to compressing and uncompressing website content, as its ratio is very high and it will uncompress data at a faster rate than the same data can be read from a hard drive if it were uncompressed. In this way, using LZ4 will speed up any kind of website that runs on a platform where the algorithm is present. The high performance requires plenty of CPU processing time, that is provided by the numerous clusters working together as a part of our platform. In addition to that, LZ4 enables us to generate several backup copies of your content every day and keep them for a month as they'll take much less space than typical backups and will be created much quicker without loading the servers.
