Data compression is the lowering of the number of bits which have to be stored or transmitted and this particular process is quite important in the internet hosting field due to the fact that info kept on hard disks is typically compressed to take less space. There are various algorithms for compressing information and they offer different effectiveness depending on the content. Some of them remove just the redundant bits, so no data will be lost, while others erase unneeded bits, which results in worse quality when your data is uncompressed. The process requires plenty of processing time, therefore a hosting server needs to be powerful enough to be able to compress and uncompress data quickly. One example how binary code can be compressed is by "remembering" that there're five sequential 1s, for example, in contrast to storing all five 1s.
Data Compression in Website Hosting
The ZFS file system that operates on our cloud web hosting platform employs a compression algorithm identified as LZ4. The latter is a lot faster and better than every other algorithm available on the market, particularly for compressing and uncompressing non-binary data i.e. web content. LZ4 even uncompresses data faster than it is read from a hard drive, which improves the overall performance of websites hosted on ZFS-based platforms. As the algorithm compresses data quite well and it does that very quickly, we're able to generate several backups of all the content stored in the website hosting accounts on our servers on a daily basis. Both your content and its backups will take reduced space and since both ZFS and LZ4 work very fast, the backup generation will not affect the performance of the web servers where your content will be stored.
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 one of the best algorithms out there and certainly the most efficient 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. That way, using LZ4 will speed up every site that runs on a platform where this algorithm is present. This high performance requires a lot of CPU processing time, that is provided by the great number of clusters working together as part of our platform. In addition to that, LZ4 makes it possible for us to generate several backups of your content every day and save them for a month as they'll take a smaller amount of space than regular backups and will be generated much more quickly without loading the servers.
