Data compression is the compacting of info by lowering the number of bits which are stored or transmitted. Consequently, the compressed data will require much less disk space than the initial one, so much more content might be stored on identical amount of space. You will find different compression algorithms which work in different ways and with a number of them only the redundant bits are erased, therefore once the info is uncompressed, there is no loss of quality. Others remove excessive bits, but uncompressing the data later on will result in lower quality compared to the original. Compressing and uncompressing content requires a large amount of system resources, particularly CPU processing time, therefore each and every web hosting platform which uses compression in real time needs to have enough power to support that attribute. An example how information can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" the number of sequential 1s or 0s there should be instead of saving the whole code.

Data Compression in Cloud Hosting

The compression algorithm which we use on the cloud hosting platform where your new cloud hosting account will be created is called LZ4 and it is used by the state-of-the-art ZFS file system which powers the platform. The algorithm is greater than the ones other file systems employ since its compression ratio is much higher and it processes data a lot quicker. The speed is most noticeable when content is being uncompressed as this happens faster than info can be read from a hard drive. Consequently, LZ4 improves the performance of each site stored on a server which uses this algorithm. We take full advantage of LZ4 in one more way - its speed and compression ratio make it possible for us to produce a number of daily backup copies of the whole content of all accounts and store them for one month. Not only do our backup copies take less space, but their generation does not slow the servers down like it often happens with alternative file systems.

Data Compression in Semi-dedicated Servers

The ZFS file system which runs on the cloud platform where your semi-dedicated server account will be created uses a powerful compression algorithm called LZ4. It is among the best algorithms out there and certainly the best one when it comes to compressing and uncompressing website content, as its ratio is very high and it'll uncompress data a lot faster than the same data can be read from a hard disk drive if it were uncompressed. Thus, using LZ4 will speed up any site that runs on a platform where this algorithm is present. The high performance requires lots of CPU processing time, that's provided by the great number of clusters working together as part of our platform. Furthermore, LZ4 allows us to generate several backups of your content every day and have them for a month as they'll take much less space than typical backups and will be generated considerably faster without loading the servers.
