The term data compression describes lowering the number of bits of data which needs to be stored or transmitted. This can be done with or without losing information, which means that what will be removed in the course of the compression will be either redundant data or unnecessary one. When the data is uncompressed later on, in the first case the content and its quality shall be identical, while in the second case the quality shall be worse. You will find different compression algorithms which are more efficient for different type of info. Compressing and uncompressing data normally takes a lot of processing time, so the server performing the action needs to have ample resources to be able to process the data quick enough. One simple example how information can be compressed is to store just how many consecutive positions should have 1 and how many should have 0 inside the binary code as an alternative to storing the particular 1s and 0s.
Data Compression in Cloud Web Hosting
The compression algorithm that we use on the cloud internet hosting platform where your new cloud web hosting
account will be created is named LZ4 and it is used by the exceptional ZFS file system that powers the platform. The algorithm is superior to the ones other file systems work with as its compression ratio is much higher and it processes data a lot faster. The speed is most noticeable when content is being uncompressed since this happens at a faster rate than data can be read from a hard disk drive. For that reason, LZ4 improves the performance of every website stored on a server which uses this algorithm. We use LZ4 in an additional way - its speed and compression ratio let us make a couple of daily backups of the full content of all accounts and keep them for 30 days. Not only do our backups take less space, but also their generation doesn't slow the servers down like it can often happen with many other file systems.
Data Compression in Semi-dedicated Hosting
The ZFS file system which 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 certainly the best one when it comes to compressing and uncompressing web content, as its ratio is very high and it can uncompress data quicker than the same data can be read from a hard drive if it were uncompressed. Thus, using LZ4 will quicken any Internet site that runs on a platform where this algorithm is enabled. The high performance requires plenty of CPU processing time, that is provided by the great number of clusters working together as part of our platform. In addition to that, LZ4 allows us to generate several backup copies of your content every day and keep them for a month as they will take a reduced amount of space than typical backups and will be created much faster without loading the servers.
