The term data compression refers to reducing the number of bits of information that needs to be stored or transmitted. You can do this with or without losing information, which means that what will be removed during the compression will be either redundant data or unnecessary one. When the data is uncompressed afterwards, in the first case the information and its quality will be the same, whereas in the second case the quality shall be worse. You can find different compression algorithms that are better for various sort of info. Compressing and uncompressing data in most cases takes lots of processing time, so the server executing the action needs to have plenty of resources in order to be able to process your data fast enough. One simple example how information can be compressed is to store just how many consecutive positions should have 1 and just 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 used by the ZFS file system which runs on our cloud internet hosting platform is named LZ4. It can improve the performance of any website hosted in a cloud web hosting account with us since not only does it compress info much better than algorithms used by other file systems, but it uncompresses data at speeds that are higher than the hard drive reading speeds. This is achieved by using a great deal of CPU processing time, that is not a problem for our platform owing to the fact that it uses clusters of powerful servers working together. One more advantage of LZ4 is that it enables us to create backup copies quicker and on lower disk space, so we shall have a couple of daily backups of your databases and files and their generation will not change the performance of the servers. In this way, we could always recover any content that you could have removed by mistake.

Data Compression in Semi-dedicated Servers

The semi-dedicated server plans which we offer are created on a powerful cloud platform which runs on the ZFS file system. ZFS uses a compression algorithm known as LZ4 that is greater than any other algorithm you will find in terms of speed and compression ratio when it comes to processing website 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 drive and for that reason, websites running on a platform where LZ4 is present will work at a higher speed. We are able to benefit from this feature although it needs quite a great deal of CPU processing time as our platform uses a wide range of powerful servers working together and we don't make accounts on a single machine like the majority of companies do. There's one more reward of using LZ4 - considering that it compresses data rather well and does that extremely fast, we can also make multiple daily backup copies of all accounts without affecting the performance of the servers and keep them for a month. This way, you'll always be able to recover any content that you erase by accident.
