Data compression is the lowering of the number of bits which should be stored or transmitted and this process is quite important in the internet hosting field since info stored on hard disk drives is generally compressed to take less space. You can find various algorithms for compressing information and they have different efficiency based upon the content. A number of them remove only the redundant bits, so no data will be lost, while others remove unnecessary bits, which results in worse quality when the data is uncompressed. This process employs plenty of processing time, therefore an internet hosting server should be powerful enough to be able to compress and uncompress data in real time. One example how binary code could be compressed is by "remembering" that there're five consecutive 1s, for example, in contrast to storing all five 1s.

Data Compression in Shared Web Hosting

The compression algorithm that we work with on the cloud hosting platform where your new shared web hosting account shall be created is named LZ4 and it's applied by the exceptional ZFS file system that powers the platform. The algorithm is better than the ones other file systems work with since its compression ratio is higher and it processes data a lot faster. The speed is most noticeable when content is being uncompressed since this happens quicker than information can be read from a hdd. For that reason, LZ4 improves the performance of each and every Internet site stored on a server which uses this particular algorithm. We use LZ4 in one more way - its speed and compression ratio let us generate several daily backups of the entire content of all accounts and store them for one month. Not only do the backups take less space, but in addition their generation will not slow the servers down like it can often happen with other file systems.

Data Compression in Semi-dedicated Hosting

The semi-dedicated hosting plans that we offer are created on a powerful cloud hosting platform that runs on the ZFS file system. ZFS uses a compression algorithm known as LZ4 that outperforms any other algorithm on the market in terms of speed and compression ratio when it comes to processing website content. This is valid particularly when data is uncompressed as LZ4 does that faster than it would be to read uncompressed data from a hard drive and as a result, sites running on a platform where LZ4 is present will function faster. We're able to take full advantage of this feature although it requires quite a lot of CPU processing time as our platform uses a huge number of powerful servers working together and we do not make accounts on a single machine like most companies do. There is another advantage of using LZ4 - considering 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 30 days. This way, you'll always be able to restore any content that you delete by accident.
