Data compression is the compacting of info by decreasing the number of bits which are stored or transmitted. Consequently, the compressed info will need considerably less disk space than the original one, so additional content might be stored using identical amount of space. You can find different compression algorithms which work in different ways and with several of them just the redundant bits are deleted, which means that once the data is uncompressed, there is no loss of quality. Others remove unneeded bits, but uncompressing the data subsequently will result in lower quality in comparison with the original. Compressing and uncompressing content requires a large amount of system resources, and in particular CPU processing time, therefore each and every hosting platform that uses compression in real time must have ample power to support that attribute. 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 keeping the entire code.
Data Compression in Cloud Web Hosting
The compression algorithm that we work with on the cloud hosting platform where your new cloud web hosting account will be created is known as LZ4 and it's applied by the advanced ZFS file system which powers the platform. The algorithm is a lot better than the ones other file systems employ as its compression ratio is much higher and it processes data significantly faster. The speed is most noticeable when content is being uncompressed since this happens more quickly than information can be read from a hard disk drive. Consequently, LZ4 improves the performance of any Internet site hosted on a server which uses this algorithm. We take advantage of LZ4 in one more way - its speed and compression ratio allow us to generate a number of daily backups of the entire content of all accounts and store them for thirty days. Not only do these backups take less space, but their generation does not slow the servers down like it can often happen with various other file systems.
Data Compression in Semi-dedicated Servers
Your semi-dedicated server account shall be created on a cloud platform which runs using the cutting-edge ZFS file system. The aforementioned uses a compression algorithm named LZ4, which is far better than alternative algorithms when it comes to compression ratio and speed. The gain is apparent especially when data is being uncompressed and not only is LZ4 faster than other algorithms, but it is also quicker in uncompressing data than a system is in reading from a hard disk drive. This is the reason why Internet sites running on a platform that uses LZ4 compression perform better as the algorithm is most efficient when it processes compressible data i.e. website content. Another advantage of using LZ4 is that the backup copies of the semi-dedicated accounts that we keep require much less space and they are generated a lot faster, which allows us to have a couple of daily backups of all your files and databases.
