Data compression is the lowering of the number of bits which have to be stored or transmitted and this process is rather important in the internet hosting field because data recorded on hard disks is typically compressed in order to take less space. You can find many different algorithms for compressing information and they have different efficiency based on the content. Some of them remove just the redundant bits, so that no data can be lost, while others delete unnecessary bits, which results in worse quality when the particular data is uncompressed. This process consumes a lot of processing time, so a web hosting server needs to be powerful enough in order to be able to compress and uncompress data in real time. One example 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 Shared Hosting
The compression algorithm which we use on the cloud web hosting platform where your new shared hosting
account shall be created is known as LZ4 and it's used by the cutting-edge ZFS file system that powers the platform. The algorithm is better than the ones other file systems use because its compression ratio is a lot higher and it processes data a lot faster. The speed is most noticeable when content is being uncompressed since this happens faster than information can be read from a hard drive. Because of this, LZ4 improves the performance of each and every site hosted on a server which uses this particular algorithm. We take advantage of LZ4 in one more way - its speed and compression ratio make it possible for us to produce several daily backup copies of the full content of all accounts and keep them for 30 days. Not only do our backups take less space, but their generation does not slow the servers down like it can often happen with other file systems.
Data Compression in Semi-dedicated Servers
If you host your websites in a semi-dedicated server
account from our firm, you will be able to experience the advantages of LZ4 - the powerful compression algorithm used by the ZFS file system that's behind our advanced cloud hosting platform. What differentiates LZ4 from all of the other algorithms out there is that it has an improved compression ratio and it is considerably faster, in particular when it comes to uncompressing website content. It does that even quicker than uncompressed information can be read from a hard drive, so your sites will perform faster. The higher speed is at the expense of using a great deal of CPU processing time, that is not an issue for our platform because it consists of multiple clusters working together. In addition to the superior performance, you'll have multiple daily backup copies at your disposal, so you'll be able to restore any deleted content with just a couple of clicks. The backups are available for an entire month and we can afford to keep them since they need significantly less space than ordinary backups.
