The term data compression identifies lowering the number of bits of data that should be saved or transmitted. This can be done with or without the loss of info, which means that what will be removed throughout the compression shall be either redundant data or unneeded one. When the data is uncompressed later on, in the first case the information and the quality will be identical, while in the second case the quality will be worse. You'll find different compression algorithms that are better for various type of info. Compressing and uncompressing data generally takes a lot of processing time, so the server performing the action must have ample resources to be able to process your data fast enough. A simple example how information can be compressed is to store how many sequential positions should have 1 and just how many should have 0 within the binary code rather than storing the actual 1s and 0s.
Data Compression in Cloud Web Hosting
The compression algorithm employed by the ZFS file system that runs on our cloud hosting platform is named LZ4. It can improve the performance of any Internet site hosted in a cloud web hosting account on our end because not only does it compress info significantly better than algorithms employed by various file systems, but also uncompresses data at speeds which are higher than the hard drive reading speeds. This can be done by using a lot of CPU processing time, which is not a problem for our platform due to the fact that it uses clusters of powerful servers working together. One more advantage of LZ4 is that it enables us to generate backup copies at a higher speed and on reduced disk space, so we shall have a couple of daily backups of your files and databases and their generation won't change the performance of the servers. This way, we can always recover the content that you may have deleted by accident.
Data Compression in Semi-dedicated Servers
The semi-dedicated server plans that we supply are created on a powerful cloud hosting platform which runs on the ZFS file system. ZFS works with a compression algorithm known as LZ4 that is better than any other algorithm out there in terms of speed and data compression ratio when it comes to processing web content. This is valid particularly when data is uncompressed since LZ4 does that faster than it would be to read uncompressed data from a hard drive and as a result, Internet sites running on a platform where LZ4 is enabled will work faster. We're able to take advantage of the feature although it needs quite a large amount of CPU processing time because our platform uses a large number of powerful servers working together and we do not make accounts on a single machine like the vast majority of companies do. There is a further reward of using LZ4 - considering that it compresses data really well and does that very fast, we can also make multiple daily backup copies of all accounts without influencing the performance of the servers and keep them for an entire month. This way, you can always bring back any content that you erase by accident.
