Data compression is the compacting of data by decreasing the number of bits that are stored or transmitted. Because of this, the compressed info will take considerably less disk space than the initial one, so a lot more content can be stored using identical amount of space. There're different compression algorithms which function in different ways and with some of them just the redundant bits are erased, so once the information is uncompressed, there's no loss of quality. Others remove unneeded bits, but uncompressing the data afterwards will result in lower quality in comparison with the original. Compressing and uncompressing content needs a significant amount of system resources, particularly CPU processing time, therefore every Internet hosting platform that employs compression in real time needs to have adequate power to support this feature. An example how information can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" what number of sequential 1s or 0s there should be instead of keeping the whole code.
Data Compression in Cloud Hosting
The ZFS file system which operates on our cloud web hosting platform uses a compression algorithm called LZ4. The latter is significantly faster and better than any other algorithm on the market, especially for compressing and uncompressing non-binary data i.e. internet content. LZ4 even uncompresses data quicker than it is read from a hard disk drive, which improves the performance of websites hosted on ZFS-based platforms. Due to the fact that the algorithm compresses data very well and it does that quickly, we are able to generate several backup copies of all the content kept in the cloud hosting accounts on our servers daily. Both your content and its backups will need less space and since both ZFS and LZ4 work very quickly, the backup generation will not affect the performance of the web hosting servers where your content will be stored.
Data Compression in Semi-dedicated Hosting
The semi-dedicated hosting plans that we supply are created on a powerful cloud platform which runs on the ZFS file system. ZFS works with a compression algorithm named LZ4 that is greater than any other algorithm available on the market in terms of speed and compression ratio when it comes to processing website content. This is valid especially when data is uncompressed since LZ4 does that more quickly than it would be to read uncompressed data from a hard disk and for that reason, sites running on a platform where LZ4 is present will function faster. We're able to take advantage of the feature although it needs quite a lot of CPU processing time as our platform uses a lot of powerful servers working together and we don't make accounts on just a single machine like most companies do. There's one more benefit of using LZ4 - considering the fact that it compresses data really well and does that speedily, we can also generate several daily backups of all accounts without influencing the performance of the servers and keep them for an entire month. This way, you'll always be able to recover any content that you erase by mistake.
