The term data compression refers to reducing the number of bits of info which should be stored or transmitted. This can be achieved with or without the loss of data, which means that what will be erased in the course of the compression will be either redundant data or unneeded one. When the data is uncompressed afterwards, in the first case the info and its quality shall be the same, while in the second case the quality will be worse. You will find different compression algorithms that are more effective for different kind of info. Compressing and uncompressing data normally takes plenty of processing time, so the server performing the action should have ample resources to be able to process the data fast enough. An example how information can be compressed is to store just how many sequential positions should have 1 and how many should have 0 inside the binary code instead of storing the actual 1s and 0s.
Data Compression in Cloud Hosting
The cloud web hosting platform where your cloud hosting account is generated uses the impressive ZFS file system. The LZ4 compression method that the latter uses is better in many aspects, and not only does it compress data better than any compression method that some other file systems use, but it's also quicker. The gains will be significant especially on compressible content like website files. Although it could sound unreasonable, uncompressing data with LZ4 is faster than reading uncompressed info from a hard drive, so the performance of every website hosted on our servers shall be upgraded. The better and faster compression rates also make it possible for us to generate numerous daily backups of the whole content in each web hosting account, so should you delete anything by mistake, the last back-up copy which we have will not be more than a few hours old. This can be done because the backups take significantly less space and their generation is quick enough, to not influence the performance of our servers.
Data Compression in Semi-dedicated Hosting
The ZFS file system that runs on the cloud platform where your semi-dedicated hosting account will be created uses a powerful compression algorithm called LZ4. It is one of the best algorithms out there and positively the most efficient one when it comes to compressing and uncompressing web content, as its ratio is very high and it'll uncompress data faster than the same data can be read from a hard disk drive if it were uncompressed. In this way, using LZ4 will quicken every Internet site that runs on a platform where this algorithm is enabled. This high performance requires plenty of CPU processing time, that is provided by the numerous clusters working together as part of our platform. Furthermore, LZ4 makes it possible for us to generate several backup copies of your content every day and save them for one month as they'll take a smaller amount of space than typical backups and will be generated much more quickly without loading the servers.
