Data compression is the compacting of data by decreasing the number of bits that are stored or transmitted. This way, the compressed data will take considerably less disk space than the initial one, so extra content can be stored on identical amount of space. You will find various compression algorithms that work in different ways and with a number of them just the redundant bits are erased, therefore once the data is uncompressed, there's no decrease in quality. Others remove excessive bits, but uncompressing the data later on will lead to lower quality in comparison with the original. Compressing and uncompressing content needs a huge amount of system resources, in particular CPU processing time, therefore any hosting platform that employs compression in real time needs to have enough power to support that feature. An example how info can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" how many consecutive 1s or 0s there should be instead of storing the actual code.

Data Compression in Cloud Website Hosting

The cloud web hosting platform where your cloud website hosting account is created employs the outstanding ZFS file system. The LZ4 compression method that the aforementioned uses is superior in many aspects, and not only does it compress data better than any compression method which some other file systems use, but it is also quicker. The benefits are significant especially on compressible content such as website files. Despite the fact that it could sound irrational, uncompressing data with LZ4 is quicker than reading uncompressed info from a hard disk, so the performance of every Internet site hosted on our servers will be boosted. The better and faster compression rates also make it possible for us to generate a number of daily backups of the full content in each and every Internet hosting account, so if you delete anything by accident, the last back-up copy that we have will not be more than several hours old. This can be done as the backups take much less space and their generation is quick enough, so as to not affect the performance of our servers.

Data Compression in Semi-dedicated Servers

Your semi-dedicated server account will be created on a cloud platform that runs on the cutting-edge ZFS file system. The latter uses a compression algorithm called LZ4, which is much better than all other algorithms when it comes to compression ratio and speed. The gain is visible particularly when data is being uncompressed and not only is LZ4 faster than other algorithms, but it is also faster in uncompressing data than a system is in reading from a hard disk. Because of this Internet sites running on a platform that uses LZ4 compression perform better as the algorithm is most effective when it processes compressible data i.e. web content. A further advantage of using LZ4 is that the backups of the semi-dedicated accounts which we keep require a lot less space and they're generated quicker, which enables us to store a couple of daily backups of all your files and databases.
