The term data compression refers to reducing the number of bits of data which has to be saved or transmitted. This can be done with or without the loss of info, which means that what will be erased in the course of the compression can be either redundant data or unneeded one. When the data is uncompressed later on, in the first case the info and the quality shall be the same, whereas in the second case the quality shall be worse. You will find different compression algorithms that are better for different sort of info. Compressing and uncompressing data in most cases takes plenty of processing time, which means that the server carrying out the action must have adequate resources in order to be able to process your info quick enough. A simple example how information can be compressed is to store just how many consecutive positions should have 1 and just how many should have 0 in the binary code instead of storing the particular 1s and 0s.
Data Compression in Cloud Web Hosting
The compression algorithm used by the ZFS file system that runs on our cloud hosting platform is known as LZ4. It can improve the performance of any site hosted in a cloud web hosting
account with us because not only does it compress data significantly better than algorithms used by other file systems, but also uncompresses data at speeds which are higher than the hard disk reading speeds. This can be done by using a great deal of CPU processing time, which is not a problem for our platform for the reason that it uses clusters of powerful servers working together. A further advantage of LZ4 is that it allows us to generate backups more speedily and on less disk space, so we shall have multiple daily backups of your files and databases and their generation won't affect the performance of the servers. This way, we could always restore the content that you may have removed by mistake.
Data Compression in Semi-dedicated Servers
In case you host your Internet sites in a semi-dedicated server
account from our firm, you can experience the advantages of LZ4 - the powerful compression algorithm employed by the ZFS file system which is behind our advanced cloud Internet hosting platform. What differentiates LZ4 from all other algorithms out there is that it has a higher compression ratio and it is considerably quicker, in particular when it comes to uncompressing website content. It does that even faster than uncompressed information can be read from a hard disk drive, so your sites will perform faster. The higher speed comes at the expense of using lots of CPU processing time, which is 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'll be able to recover any deleted content with just a couple of clicks. The backup copies are available for a whole month and we can afford to store them since they need significantly less space than conventional backups.
