Data compression is the compacting of data by reducing the number of bits which are stored or transmitted. As a result, the compressed data will require less disk space than the initial one, so extra content can be stored using the same amount of space. You can find different compression algorithms that work in different ways and with some of them just the redundant bits are erased, which means that once the data is uncompressed, there is no decrease in quality. Others delete unneeded bits, but uncompressing the data later will lead to reduced quality in comparison with the original. Compressing and uncompressing content consumes a significant amount of system resources, especially CPU processing time, therefore any hosting platform which employs compression in real time must have enough power to support that attribute. An example how information can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" the number of consecutive 1s or 0s there should be instead of keeping the whole code.
Data Compression in Cloud Web Hosting
The compression algorithm that we employ on the cloud internet hosting platform where your new cloud web hosting account will be created is known as LZ4 and it is used by the state-of-the-art ZFS file system that powers the platform. The algorithm is much better than the ones other file systems employ as its compression ratio is a lot higher and it processes data considerably faster. The speed is most noticeable when content is being uncompressed since this happens more quickly than info can be read from a hard drive. For that reason, LZ4 improves the performance of each Internet site hosted on a server that uses this algorithm. We take full advantage of LZ4 in one more way - its speed and compression ratio make it possible for us to produce a number of daily backup copies of the full content of all accounts and keep them for thirty days. Not only do our backups take less space, but also their generation will not slow the servers down like it often happens with other file systems.
Data Compression in Semi-dedicated Hosting
The semi-dedicated hosting plans that we supply are created on a powerful cloud hosting platform that runs on the ZFS file system. ZFS employs a compression algorithm named LZ4 that is superior to any other algorithm you can find in terms of speed and compression ratio when it comes to processing web content. This is valid especially 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 present will function faster. We're able to take advantage of this feature regardless of the fact that it needs quite a large amount of CPU processing time as our platform uses a number of powerful servers working together and we do not create accounts on a single machine like a lot of companies do. There's one more advantage of using LZ4 - since it compresses data very well and does that very quickly, we can also make several daily backups of all accounts without affecting the performance of the servers and keep them for 30 days. By doing this, you will always be able to restore any content that you erase by mistake.
