The term data compression identifies lowering the number of bits of data which should be saved or transmitted. This can be done with or without losing information, so what will be erased during the compression shall be either redundant data or unneeded one. When the data is uncompressed later on, in the first case the content and the quality will be identical, while in the second case the quality will be worse. There are different compression algorithms which are more efficient for different type of information. Compressing and uncompressing data generally takes lots of processing time, so the server carrying out the action should have ample resources to be able to process the info fast enough. One simple example how information can be compressed is to store just how many sequential positions should have 1 and just how many should have 0 within the binary code as an alternative to storing the actual 1s and 0s.
Data Compression in Cloud Website Hosting
The compression algorithm used by the ZFS file system that runs on our cloud internet hosting platform is called LZ4. It can supercharge the performance of any Internet site hosted in a cloud website hosting
account with us because not only does it compress data much better than algorithms used by alternative file systems, but also uncompresses data at speeds which are higher than the HDD reading speeds. This is achieved by using a great deal of CPU processing time, that is not a problem for our platform for the reason that it uses clusters of powerful servers working together. An additional advantage of LZ4 is that it allows us to make backups at a higher speed and on less disk space, so we shall have several daily backups of your files and databases and their generation will not change the performance of the servers. This way, we could always recover any content that you may have removed by mistake.
Data Compression in Semi-dedicated Hosting
In case you host your Internet sites in a semi-dedicated hosting
account from our company, you can experience the advantages of LZ4 - the powerful compression algorithm employed by the ZFS file system that is behind our advanced cloud web hosting platform. What separates LZ4 from all the other algorithms out there is that it has a higher compression ratio and it is considerably faster, especially when it comes to uncompressing web content. It does that even faster than uncompressed info can be read from a hard drive, so your websites will perform faster. The higher speed is at the expense of using plenty of CPU processing time, which is not an issue for our platform since it consists of a lot of clusters working together. In combination with the improved performance, you will also have multiple daily backup copies at your disposal, so you can restore any deleted content with a few clicks. The backups are available for an entire month and we can afford to store them because they take a lot less space compared to conventional backups.
