The term data compression refers to reducing the number of bits of data that needs to be saved or transmitted. This can be achieved with or without the loss of information, so what will be deleted throughout the compression shall be either redundant data or unneeded one. When the data is uncompressed subsequently, in the first case the information and its quality will be the same, whereas in the second case the quality will be worse. There're different compression algorithms which are better for various type of data. Compressing and uncompressing data normally takes lots of processing time, which means that the server executing the action needs to have plenty of resources in order to be able to process your info fast enough. An example how information can be compressed is to store just how many consecutive positions should have 1 and how many should have 0 within the binary code instead of storing the particular 1s and 0s.
Data Compression in Cloud Web Hosting
The compression algorithm used by the ZFS file system that runs on our cloud web hosting platform is called LZ4. It can boost the performance of any Internet site hosted in a cloud web hosting account with us as not only does it compress info much better than algorithms used by various other file systems, but also uncompresses data at speeds that are higher than the hard disk drive reading speeds. This can be done by using a great deal of CPU processing time, which is not a problem for our platform considering that it uses clusters of powerful servers working together. An additional advantage of LZ4 is that it enables us to create backups a lot faster and on lower disk space, so we can have multiple daily backups of your files and databases and their generation will not affect the performance of the servers. This way, we can always restore all content that you may have removed by accident.
Data Compression in Semi-dedicated Hosting
The semi-dedicated hosting plans which we supply are created on a powerful cloud hosting platform that runs on the ZFS file system. ZFS works with a compression algorithm named LZ4 that is better than any other algorithm you will find in terms of speed and data compression ratio when it comes to processing website content. This is valid especially when data is uncompressed since LZ4 does that much faster than it would be to read uncompressed data from a hard drive and for that reason, sites running on a platform where LZ4 is present will function quicker. We're able to take advantage of the feature regardless of the fact that it requires quite a considerable amount of CPU processing time as our platform uses many powerful servers working together and we never create accounts on a single machine like the majority of companies do. There's a further benefit of using LZ4 - considering that it compresses data very well and does that very quickly, we can also generate several daily backup copies of all accounts without affecting the performance of the servers and keep them for a month. That way, you'll always be able to recover any content that you delete by mistake.
