Data compression is the decrease of the number of bits that have to be saved or transmitted and this particular process is rather important in the web hosting field as info kept on hard disk drives is usually compressed to take less space. There are many different algorithms for compressing data and they have different efficiency based on the content. A lot of them remove just the redundant bits, so no data can be lost, while others delete unneeded bits, which leads to worse quality when your data is uncompressed. This method requires a lot of processing time, which means that a hosting server should be powerful enough to be able to compress and uncompress data immediately. An instance how binary code can be compressed is by "remembering" that there're five consecutive 1s, for example, as an alternative to storing all five 1s.
Data Compression in Cloud Website Hosting
The compression algorithm which we work with on the cloud web hosting platform where your new cloud website hosting
account will be created is called LZ4 and it is applied by the cutting-edge ZFS file system which powers the system. The algorithm is far better than the ones other file systems employ since its compression ratio is higher and it processes data considerably quicker. The speed is most noticeable when content is being uncompressed as this happens quicker than data can be read from a hard drive. Therefore, LZ4 improves the performance of each and every Internet site stored on a server that uses this particular algorithm. We take advantage of LZ4 in one more way - its speed and compression ratio make it possible for us to produce several daily backups of the entire content of all accounts and keep them for 30 days. Not only do these backups take less space, but their generation won't slow the servers down like it can often happen with alternative file systems.
Data Compression in Semi-dedicated Hosting
The semi-dedicated hosting
plans that we supply are created on a powerful cloud hosting platform which runs on the ZFS file system. ZFS employs a compression algorithm known as LZ4 that is greater than any other algorithm these days in terms of speed and compression ratio when it comes to processing web content. This is valid particularly when data is uncompressed as LZ4 does that quicker than it would be to read uncompressed data from a hard disk drive and because of this, sites running on a platform where LZ4 is present will function faster. We're able to take advantage of the feature despite of the fact that it requires quite a lot of CPU processing time as our platform uses a large number of powerful servers working together and we don't make accounts on a single machine like the majority of companies do. There is a further advantage of using LZ4 - considering that it compresses data rather well and does that extremely fast, we can also make multiple daily backup copies of all accounts without affecting the performance of the servers and keep them for an entire month. By doing this, you can always bring back any content that you erase by accident.
