The term data compression describes lowering the number of bits of information that needs to be saved or transmitted. You can do this with or without the loss of info, so what will be deleted in the course of the compression shall be either redundant data or unneeded one. When the data is uncompressed later on, in the first case the data and the quality will be identical, whereas in the second case the quality will be worse. You'll find various compression algorithms that are more efficient for various kind of information. Compressing and uncompressing data in most cases takes lots of processing time, which means that the server performing the action must have enough resources in order to be able to process the data fast enough. One simple example how information can be compressed is to store how many consecutive positions should have 1 and just how many should have 0 within the binary code instead of storing the actual 1s and 0s.
Data Compression in Cloud Website Hosting
The compression algorithm used by the ZFS file system which runs on our cloud web hosting platform is known as LZ4. It can boost the performance of any Internet site hosted in a cloud website hosting
account with us since not only does it compress info more efficiently than algorithms employed by various other file systems, but it also uncompresses data at speeds that are higher than the HDD reading speeds. This is achieved by using a lot of CPU processing time, which is not a problem for our platform owing to the fact that it uses clusters of powerful servers working together. A further advantage of LZ4 is that it allows us to generate backup copies faster and on less disk space, so we can have multiple daily backups of your databases and files and their generation will not influence the performance of the servers. That way, we could always restore all content that you could have removed by accident.
Data Compression in Semi-dedicated Servers
The semi-dedicated server
plans that we offer are created on a powerful cloud hosting platform that runs on the ZFS file system. ZFS employs 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 especially when data is uncompressed because LZ4 does that much faster than it would be to read uncompressed data from a hard disk and owing to this, sites running on a platform where LZ4 is enabled will work faster. We're able to take advantage of this feature despite of the fact that it needs quite a large amount of CPU processing time because our platform uses many powerful servers working together and we don't create accounts on a single machine like most companies do. There's an additional reward of using LZ4 - since it compresses data rather well and does that extremely fast, we can also make several daily backup copies of all accounts without influencing the performance of the servers and keep them for 30 days. That way, you will always be able to restore any content that you erase by accident.
