Data compression is the compacting of data by decreasing the number of bits which are stored or transmitted. Consequently, the compressed data will need much less disk space than the original one, so additional content might be stored using the same amount of space. There're various compression algorithms which function in different ways and with some of them only the redundant bits are erased, which means that once the info is uncompressed, there's no loss of quality. Others remove excessive bits, but uncompressing the data at a later time will result in lower quality in comparison with the original. Compressing and uncompressing content needs a large amount of system resources, in particular CPU processing time, therefore every web hosting platform which uses compression in real time should have enough power to support this feature. An example how information can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" what number of consecutive 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 internet hosting platform where your new cloud web hosting account will be created is named LZ4 and it's used by the exceptional ZFS file system which powers the platform. The algorithm is superior to the ones other file systems employ since its compression ratio is a lot higher and it processes data significantly faster. The speed is most noticeable when content is being uncompressed since this happens more quickly than info can be read from a hard disk. For that reason, LZ4 improves the performance of any site hosted on a server that uses the algorithm. We use LZ4 in an additional way - its speed and compression ratio let us produce a number of daily backup copies of the whole content of all accounts and store them for thirty days. Not only do these backup copies take less space, but in addition their generation does not slow the servers down like it often happens with other file systems.
Data Compression in Semi-dedicated Hosting
The ZFS file system that runs on the cloud platform where your semi-dedicated hosting account will be created uses a powerful compression algorithm called LZ4. It's one of the best algorithms out there and certainly the most efficient one when it comes to compressing and uncompressing web content, as its ratio is very high and it can uncompress data much faster than the same data can be read from a hard drive if it were uncompressed. That way, using LZ4 will boost any Internet site that runs on a platform where the algorithm is present. The high performance requires plenty of CPU processing time, that's provided by the multitude of clusters working together as a part of our platform. In addition, LZ4 allows us to generate several backup copies of your content every day and have them for one month as they'll take much less space than regular backups and will be created considerably quicker without loading the servers.
