Data compression is the compacting of data by decreasing the number of bits which are stored or transmitted. Thus, the compressed data takes considerably less disk space than the initial one, so more content could be stored on identical amount of space. You can find many different compression algorithms that work in different ways and with some of them just the redundant bits are erased, which means that once the info is uncompressed, there is no decrease in quality. Others delete unnecessary bits, but uncompressing the data at a later time will result in lower quality compared to the original. Compressing and uncompressing content needs a huge amount of system resources, especially CPU processing time, so each and every Internet hosting platform which uses compression in real time must have sufficient power to support this attribute. An example how info can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" how many sequential 1s or 0s there should be instead of storing the actual code.
Data Compression in Cloud Web Hosting
The ZFS file system which operates on our cloud Internet hosting platform uses a compression algorithm named LZ4. The latter is significantly faster and better than any other algorithm available on the market, particularly for compressing and uncompressing non-binary data i.e. internet content. LZ4 even uncompresses data quicker than it is read from a hard disk drive, which improves the performance of Internet sites hosted on ZFS-based platforms. Due to the fact that the algorithm compresses data really well and it does that quickly, we are able to generate several backup copies of all the content kept in the cloud web hosting accounts on our servers on a daily basis. Both your content and its backups will require less space and since both ZFS and LZ4 work extremely fast, the backup generation will not influence the performance of the hosting servers where your content will be kept.
Data Compression in Semi-dedicated Hosting
The ZFS file system which runs on the cloud platform where your semi-dedicated hosting account will be created uses a powerful compression algorithm called LZ4. It is one of the best algorithms out there and definitely the best one when it comes to compressing and uncompressing website content, as its ratio is very high and it will uncompress data much faster than the same data can be read from a hard disk drive if it were uncompressed. In this way, using LZ4 will quicken every site that runs on a platform where the algorithm is present. The high performance requires lots of CPU processing time, that's provided by the multitude of clusters working together as a part of our platform. In addition to that, LZ4 enables us to generate several backup copies of your content every day and save them for one month as they will take much less space than regular backups and will be generated much faster without loading the servers.
