Data compression is the lowering of the number of bits that need to be stored or transmitted and the process is quite important in the web hosting field since info located on hard disks is usually compressed to take less space. You will find many different algorithms for compressing information and they offer different efficiency depending on the content. A number of them remove only the redundant bits, so that no data can be lost, while others erase unneeded bits, which leads to worse quality when the data is uncompressed. The method needs a lot of processing time, therefore a hosting server has to be powerful enough so as to be able to compress and uncompress data quickly. An instance how binary code could be compressed is by "remembering" that there are five consecutive 1s, for example, as an alternative to storing all five 1s.

Data Compression in Cloud Website Hosting

The ZFS file system which operates on our cloud web hosting platform employs a compression algorithm named LZ4. The latter is a lot faster and better than any other algorithm you can find, particularly for compressing and uncompressing non-binary data i.e. web content. LZ4 even uncompresses data quicker than it is read from a hard disk, which improves the overall performance of sites hosted on ZFS-based platforms. Because the algorithm compresses data quite well and it does that quickly, we can generate several backup copies of all the content kept in the cloud website hosting accounts on our servers every day. Both your content and its backups will take reduced space and since both ZFS and LZ4 work extremely fast, the backup generation will not affect the performance of the hosting servers where your content will be kept.

Data Compression in Semi-dedicated Hosting

The semi-dedicated hosting plans that we provide are created on a powerful cloud hosting platform which runs on the ZFS file system. ZFS uses a compression algorithm called LZ4 that is greater than any other algorithm available on the market in terms of speed and data compression ratio when it comes to processing website content. This is valid especially when data is uncompressed as LZ4 does that quicker than it would be to read uncompressed data from a hard disk and owing to this, Internet sites running on a platform where LZ4 is present will work at a higher speed. We're able to benefit from this feature regardless of the fact that it requires quite a lot of CPU processing time because our platform uses a lot of powerful servers working together and we don't create accounts on a single machine like many companies do. There's an additional 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. This way, you can always restore any content that you erase by mistake.
