Data compression is the lowering of the number of bits that should be stored or transmitted and the process is quite important in the web hosting field because information stored on HDDs is generally compressed in order to take less space. You'll find many different algorithms for compressing data and they provide different efficiency depending on the content. Some of them remove only the redundant bits, so no data can be lost, while others remove unneeded bits, which leads to worse quality when the particular data is uncompressed. This process consumes a lot of processing time, so a hosting server should be powerful enough to be able to compress and uncompress data quickly. An illustration how binary code may be compressed is by "remembering" that there're five sequential 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 hosting platform uses a compression algorithm called LZ4. The latter is a lot faster and better than every other algorithm on the market, particularly for compressing and uncompressing non-binary data i.e. web 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. As the algorithm compresses data quite well and it does that quickly, we're able to generate several backups of all the content kept in the cloud website hosting accounts on our servers on a daily basis. Both your content and its backups will take less space and since both ZFS and LZ4 work very quickly, the backup generation will not influence the performance of the web servers where your content will be stored.

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 uses a compression algorithm called LZ4 that surpasses any other algorithm on the market in terms of speed and data compression ratio when it comes to processing web content. This is valid particularly when data is uncompressed as LZ4 does that more quickly than it would be to read uncompressed data from a hard disk and owing to this, sites running on a platform where LZ4 is present will work faster. We are able to take full advantage of this feature regardless of the fact that it needs quite a large amount of CPU processing time because our platform uses many powerful servers working together and we do not create accounts on a single machine like the majority of companies do. There is another advantage of using LZ4 - considering the fact that it compresses data rather well and does that very fast, we can also generate multiple daily backups of all accounts without influencing the performance of the servers and keep them for an entire month. By doing this, you will always be able to recover any content that you erase by mistake.
