The term data compression identifies decreasing the number of bits of data which should be stored or transmitted. This can be done with or without losing info, which means that what will be deleted at the time of the compression will be either redundant data or unnecessary one. When the data is uncompressed subsequently, in the first case the information and the quality will be identical, while in the second case the quality will be worse. You can find different compression algorithms which are better for different kind of information. Compressing and uncompressing data often takes a lot of processing time, which means that the server carrying out the action should have enough resources 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 how many should have 0 inside the binary code instead of storing the particular 1s and 0s.
Data Compression in Website Hosting
The compression algorithm employed by the ZFS file system that runs on our cloud hosting platform is known as LZ4. It can supercharge the performance of any Internet site hosted in a website hosting account on our end as not only does it compress info more efficiently than algorithms used by various other file systems, but it also uncompresses data at speeds which are higher than the hard disk drive reading speeds. This can be done by using a great deal of CPU processing time, that is not a problem for our platform because it uses clusters of powerful servers working together. One more advantage of LZ4 is that it enables us to generate backup copies more speedily and on reduced disk space, so we can have a couple of daily backups of your databases and files and their generation will not change the performance of the servers. That way, we could always restore all content that you may have deleted by mistake.
Data Compression in Semi-dedicated Hosting
The semi-dedicated hosting plans that we provide are created on a powerful cloud hosting platform which runs on the ZFS file system. ZFS employs a compression algorithm named LZ4 that outperforms any other algorithm available on the market in terms of speed and data compression ratio when it comes to processing web content. This is valid particularly when data is uncompressed because LZ4 does that a lot faster than it would be to read uncompressed data from a hard disk drive and because of this, websites running on a platform where LZ4 is enabled will function faster. We are able to benefit from the feature despite of the fact that it needs quite a large amount of CPU processing time because our platform uses a number of powerful servers working together and we don't make accounts on a single machine like many companies do. There is a further reward of using LZ4 - given that it compresses data very well and does that speedily, 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. By doing this, you will always be able to restore any content that you delete by accident.
