Data compression is the reduction of the number of bits that have to be stored or transmitted and this particular process is rather important in the internet hosting field since information recorded on hard disks is often compressed so as to take less space. You'll find various algorithms for compressing info and they have different efficiency depending on the content. A lot of them remove only the redundant bits, so no data can be lost, while others delete unnecessary bits, which leads to worse quality once the particular data is uncompressed. This method requires a lot of processing time, therefore a hosting server has to be powerful enough in order to be able to compress and uncompress data instantly. An illustration how binary code could be compressed is by "remembering" that there are five sequential 1s, for example, in contrast to storing all five 1s.
Data Compression in Website Hosting
The ZFS file system which operates on our cloud web hosting platform uses a compression algorithm identified as LZ4. The latter is substantially faster and better than every other algorithm out there, particularly for compressing and uncompressing non-binary data i.e. internet content. LZ4 even uncompresses data faster than it is read from a hard disk drive, which improves the overall performance of websites hosted on ZFS-based platforms. Due to the fact that the algorithm compresses data quite well and it does that very quickly, we can generate several backup copies of all the content kept in the website hosting accounts on our servers on a daily basis. Both your content and its backups will require less space and since both ZFS and LZ4 work very fast, the backup generation will not change the performance of the web servers where your content will be kept.
Data Compression in Semi-dedicated Servers
The semi-dedicated server plans which we provide are created on a powerful cloud platform that runs on the ZFS file system. ZFS works with a compression algorithm called LZ4 that exceeds any other algorithm available in terms of speed and compression ratio when it comes to processing website content. This is valid especially when data is uncompressed because LZ4 does that more quickly than it would be to read uncompressed data from a hard 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 regardless of the fact that it requires quite a large amount of CPU processing time because our platform uses a lot of powerful servers working together and we never make accounts on a single machine like the vast majority of companies do. There is one more reward of using LZ4 - since it compresses data rather well and does that very quickly, we can also make several daily backup copies of all accounts without affecting the performance of the servers and keep them for a month. By doing this, you will always be able to restore any content that you delete by accident.
