Data compression is the reduction of the number of bits which have to be stored or transmitted and this process is rather important in the web hosting field as data recorded on hard disk drives is often compressed to take less space. There're many different algorithms for compressing data and they offer different efficiency depending on the content. Some of them remove only the redundant bits, so no data can be lost, while others erase unnecessary bits, which results in worse quality once your data is uncompressed. The method employs plenty of processing time, which means that a web hosting server should be powerful enough so as to be able to compress and uncompress data right away. One example how binary code may be compressed is by "remembering" that there are five sequential 1s, for example, as an alternative to storing all five 1s.

Data Compression in Cloud Web Hosting

The compression algorithm employed by the ZFS file system that runs on our cloud web hosting platform is named LZ4. It can enhance the performance of any site hosted in a cloud web hosting account on our end since not only does it compress info much better than algorithms used by alternative file systems, but it uncompresses data at speeds that are higher than the hard 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 allows us to generate backup copies much quicker and on reduced disk space, so we can have several daily backups of your files and databases and their generation will not influence the performance of the servers. In this way, we can always restore the content that you may have removed by mistake.

Data Compression in Semi-dedicated Servers

The semi-dedicated server plans which we offer are created on a powerful cloud platform that runs on the ZFS file system. ZFS uses a compression algorithm known as LZ4 that is superior to 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 because LZ4 does that more rapidly than it would be to read uncompressed data from a hard disk drive and owing to this, sites running on a platform where LZ4 is present will function at a higher speed. We can benefit from the feature regardless of the fact that it needs quite a large amount of CPU processing time as our platform uses a huge number of powerful servers working together and we do not create accounts on a single machine like the majority of companies do. There's a further advantage of using LZ4 - given that it compresses data really well and does that very quickly, we can also generate multiple daily backups of all accounts without influencing the performance of the servers and keep them for an entire month. This way, you can always restore any content that you erase by accident.
