Data compression is the reduction of the number of bits which need to be saved or transmitted and this particular process is very important in the internet hosting field due to the fact that data located on hard disks is generally compressed to take less space. You can find different algorithms for compressing information and they have different efficiency depending on the content. Some of them remove just the redundant bits, so no data can be lost, while others delete unneeded bits, which leads to worse quality once the data is uncompressed. This process requires a lot of processing time, so an internet hosting server should be powerful enough to be able to compress and uncompress data immediately. An illustration how binary code may be compressed is by "remembering" that there're five sequential 1s, for example, rather than storing all five 1s.
Data Compression in Website Hosting
The ZFS file system which operates on our cloud web hosting platform employs a compression algorithm named LZ4. The aforementioned is a lot faster and better than every other algorithm available on the market, particularly for compressing and uncompressing non-binary data i.e. internet content. LZ4 even uncompresses data quicker than it is read from a hard disk, which improves the overall performance of websites hosted on ZFS-based platforms. Due to the fact that the algorithm compresses data very well and it does that very fast, we're able to generate several backup copies of all the content kept in the website hosting accounts on our servers daily. Both your content and its backups will take less space and since both ZFS and LZ4 work very quickly, the backup generation will not change the performance of the web servers where your content will be kept.
Data Compression in Semi-dedicated Hosting
The semi-dedicated hosting plans which we offer are created on a powerful cloud platform that runs on the ZFS file system. ZFS employs a compression algorithm named LZ4 that is superior to any other algorithm available in terms of speed and data compression ratio when it comes to processing web content. This is valid especially when data is uncompressed because LZ4 does that a lot faster than it would be to read uncompressed data from a hard disk drive and as a result, sites running on a platform where LZ4 is present will work faster. We're able to benefit from the feature although it requires quite a lot of CPU processing time as our platform uses a lot of powerful servers working together and we do not create accounts on a single machine like most companies do. There's one more benefit of using LZ4 - considering the fact that it compresses data very well and does that very fast, we can also make multiple daily backup copies of all accounts without affecting the performance of the servers and keep them for a month. This way, you will always be able to bring back any content that you delete by accident.
