Data compression is the lowering of the number of bits that should be stored or transmitted and the process is very important in the internet hosting field as data located on HDDs is typically compressed to take less space. You can find different algorithms for compressing information and they provide different efficiency depending on the content. A number of them remove only the redundant bits, so that no data can be lost, while others remove unneeded bits, which leads to worse quality once the particular data is uncompressed. This method needs plenty of processing time, which means that a hosting server should be powerful enough in order to be able to compress and uncompress data immediately. An instance how binary code can be compressed is by "remembering" that there're five sequential 1s, for example, rather than storing all five 1s.
Data Compression in Cloud Hosting
The compression algorithm which we use on the cloud web hosting platform where your new cloud hosting
account will be created is known as LZ4 and it's applied by the cutting-edge ZFS file system that powers the system. The algorithm is a lot better than the ones other file systems use as 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 faster than info can be read from a hard drive. Because of this, LZ4 improves the performance of each and every site stored on a server that uses this particular algorithm. We take advantage of LZ4 in one more way - its speed and compression ratio let us produce a couple of daily backups of the entire content of all accounts and keep them for 30 days. Not only do our backup copies take less space, but their generation will not slow the servers down like it can often happen 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 positively the best one when it comes to compressing and uncompressing web content, as its ratio is very high and it can uncompress data at a higher speed than the same data can be read from a hard drive if it were uncompressed. This way, using LZ4 will speed up every website that runs on a platform where this algorithm is present. The high performance requires a lot of CPU processing time, that's provided by the great number of clusters working together as part of our platform. What's more, LZ4 enables us to generate several backup copies of your content every day and have them for one month as they'll take a reduced amount of space than regular backups and will be created considerably faster without loading the servers.
