Data compression is the reduction of the number of bits which have to be saved or transmitted and the process is really important in the web hosting field because information recorded on hard disks is often compressed so as to take less space. There're various algorithms for compressing info and they have different efficiency based on the content. Many of them remove just the redundant bits, so that no data can be lost, while others remove unneeded bits, which leads to worse quality when the data is uncompressed. The process uses a lot of processing time, which means that a web hosting server has to be powerful enough so as to be able to compress and uncompress data in real time. An illustration how binary code could be compressed is by "remembering" that there're five consecutive 1s, for example, as an alternative to storing all five 1s.

Data Compression in Website Hosting

The compression algorithm employed by the ZFS file system which runs on our cloud internet hosting platform is called LZ4. It can boost the performance of any website hosted in a website hosting account on our end since not only does it compress data more efficiently than algorithms employed by various file systems, but it uncompresses data at speeds that are higher than the hard drive reading speeds. This is achieved by using a lot of CPU processing time, that is not a problem for our platform considering that it uses clusters of powerful servers working together. A further advantage of LZ4 is that it enables us to create backup copies at a higher speed and on lower 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 restore all of the content that you may have deleted by mistake.

Data Compression in Semi-dedicated Servers

The semi-dedicated server plans that we supply are created on a powerful cloud platform that runs on the ZFS file system. ZFS employs a compression algorithm named LZ4 that outperforms any other algorithm these days 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 more quickly than it would be to read uncompressed data from a hard disk and for that reason, Internet sites running on a platform where LZ4 is enabled will function faster. We are able to benefit from the feature regardless of the fact that it needs quite a lot of CPU processing time as our platform uses numerous powerful servers working together and we do not create accounts on just a single machine like the vast majority of companies do. There's one more advantage of using LZ4 - considering the fact that it compresses data rather well and does that extremely fast, we can also generate several daily backup copies of all accounts without influencing the performance of the servers and keep them for 30 days. By doing this, you will always be able to recover any content that you delete by accident.
