Data compression is the compacting of info by decreasing the number of bits which are stored or transmitted. As a result, the compressed info will require less disk space than the original one, so more content might be stored using the same amount of space. You can find different compression algorithms which work in different ways and with some of them just the redundant bits are removed, so once the data is uncompressed, there is no loss of quality. Others erase excessive bits, but uncompressing the data later will lead to lower quality compared to the original. Compressing and uncompressing content requires a huge amount of system resources, and in particular CPU processing time, so each and every web hosting platform that employs compression in real time needs to have enough power to support that attribute. An example how data can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" the number of consecutive 1s or 0s there should be instead of storing the entire code.

Data Compression in Cloud Web Hosting

The ZFS file system which is run on our cloud hosting platform employs a compression algorithm named LZ4. The latter is considerably faster and better than any other algorithm out there, 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 performance of websites hosted on ZFS-based platforms. As the algorithm compresses data very well and it does that very quickly, we're able to generate several backup copies of all the content stored in the cloud web 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 influence the performance of the hosting servers where your content will be stored.

Data Compression in Semi-dedicated Servers

Your semi-dedicated server account shall be created on a cloud platform which is run on the state-of-the-art ZFS file system. The latter uses a compression algorithm known as LZ4, that is significantly better than all the other algorithms regarding compression ratio and speed. The gain is significant particularly when data is being uncompressed and not only is LZ4 quicker than other algorithms, but it is also faster in uncompressing data than a system is in reading from a hard drive. That's why Internet sites running on a platform that uses LZ4 compression perform faster since the algorithm is most effective when it processes compressible data i.e. website content. An additional advantage of using LZ4 is that the backups of the semi-dedicated accounts which we keep need significantly less space and they're generated quicker, which enables us to have multiple daily backups of all your files and databases.
