Data compression is the compacting of data by reducing the number of bits that are stored or transmitted. This way, the compressed info requires considerably less disk space than the initial one, so more content could be stored on the same amount of space. There're various compression algorithms that function in different ways and with a lot of them only the redundant bits are deleted, therefore once the info is uncompressed, there's no decrease in quality. Others delete excessive bits, but uncompressing the data subsequently will lead to reduced quality compared to the original. Compressing and uncompressing content requires a significant amount of system resources, particularly CPU processing time, so any web hosting platform which employs compression in real time must have adequate power to support this feature. An example how info can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" how many sequential 1s or 0s there should be instead of storing the entire code.

Data Compression in Cloud Hosting

The ZFS file system that runs on our cloud hosting platform employs a compression algorithm called LZ4. The aforementioned is a lot faster and better than any other algorithm you will find, especially for compressing and uncompressing non-binary data i.e. web content. LZ4 even uncompresses data quicker than it is read from a hard disk drive, which improves the performance of sites hosted on ZFS-based platforms. Since the algorithm compresses data really well and it does that very quickly, we're able to generate several backup copies of all the content stored in the cloud 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 affect the performance of the web servers where your content will be stored.

Data Compression in Semi-dedicated Hosting

Your semi-dedicated hosting account shall be created on a cloud platform that runs on the innovative ZFS file system. The aforementioned uses a compression algorithm named LZ4, which is significantly better than all other algorithms when it comes to 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 disk drive. That is why websites running on a platform that uses LZ4 compression perform faster since the algorithm is most effective when it processes compressible data i.e. site content. An additional advantage of using LZ4 is that the backups of the semi-dedicated accounts that we keep need significantly less space and they're generated a lot faster, which allows us to store a couple of daily backups of your files and databases.
