Data compression is the decrease of the number of bits which need to be saved or transmitted and this particular process is quite important in the web hosting field due to the fact that info located on HDDs is often compressed to take less space. You will find different algorithms for compressing info and they offer different effectiveness depending on the content. A number of them remove just the redundant bits, so no data can be lost, while others remove unnecessary bits, which results in worse quality when the data is uncompressed. This process uses plenty of processing time, therefore an internet hosting server should be powerful enough so as to be able to compress and uncompress data quickly. 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 Shared Hosting
The compression algorithm used by the ZFS file system that runs on our cloud web hosting platform is named LZ4. It can supercharge the performance of any website hosted in a shared hosting
account on our end since not only does it compress info significantly better than algorithms employed by various other file systems, but it also uncompresses data at speeds which are higher than the hard disk reading speeds. This is achieved by using a great deal of CPU processing time, which is not a problem for our platform owing to the fact that it uses clusters of powerful servers working together. An additional advantage of LZ4 is that it enables us to generate backup copies much more quickly and on lower disk space, so we shall have several daily backups of your files and databases and their generation won't influence the performance of the servers. This way, we can always restore all of the content that you may have erased by accident.
Data Compression in Semi-dedicated Servers
If you host your Internet sites in a semi-dedicated server
account from our company, you will be able to experience the advantages of LZ4 - the powerful compression algorithm employed by the ZFS file system which is behind our advanced cloud web hosting platform. What separates LZ4 from all other algorithms out there is that it has a higher compression ratio and it is much quicker, in particular when it comes to uncompressing web content. It does that even quicker than uncompressed data can be read from a hard drive, so your websites will perform faster. The higher speed is at the expense of using a considerable amount of CPU processing time, that's not a problem for our platform as it consists of a lot of clusters working together. Along with the superior performance, you'll have multiple daily backup copies at your disposal, so you can recover any deleted content with a couple of clicks. The backup copies are available for an entire month and we can afford to store them as they need considerably less space compared to traditional backups.
