The term data compression identifies reducing the number of bits of information that should be saved or transmitted. This can be done with or without the loss of information, so what will be removed during the compression will be either redundant data or unnecessary one. When the data is uncompressed later on, in the first case the information and the quality will be the same, while in the second case the quality shall be worse. You'll find different compression algorithms which are more efficient for different sort of information. Compressing and uncompressing data frequently takes lots of processing time, which means that the server performing the action should have adequate resources to be able to process your info fast enough. A simple example how information can be compressed is to store how many sequential positions should have 1 and how many should have 0 inside the binary code as an alternative to 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 internet hosting platform is called LZ4. It can enhance 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 employed by other file systems, but also uncompresses data at speeds which are higher than the hard disk reading speeds. This can be done by using a great deal of CPU processing time, that is not a problem for our platform due to the fact that it uses clusters of powerful servers working together. A further advantage of LZ4 is that it enables us to make backup copies much more rapidly and on reduced disk space, so we will have a couple of daily backups of your files and databases and their generation will not influence the performance of the servers. In this way, we could always restore all content that you could have erased by accident.

Data Compression in Semi-dedicated Hosting

The semi-dedicated hosting plans that we provide are created on a powerful cloud platform that runs on the ZFS file system. ZFS works with a compression algorithm known as LZ4 that outperforms any other algorithm available on the market in terms of speed and compression ratio when it comes to processing web content. This is valid especially when data is uncompressed because LZ4 does that faster than it would be to read uncompressed data from a hard disk and owing to this, Internet sites running on a platform where LZ4 is enabled will function quicker. We can benefit from this feature regardless of the fact that it needs quite a large amount of CPU processing time as our platform uses a large number of powerful servers working together and we do not create accounts on a single machine like the vast majority of companies do. There is one more reward of using LZ4 - considering that it compresses data really well and does that very fast, we can also generate several daily backup copies of all accounts without affecting 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 mistake.
