The term data compression describes lowering the number of bits of info which has to be stored or transmitted. You can do this with or without losing data, so what will be deleted throughout the compression can be either redundant data or unneeded one. When the data is uncompressed afterwards, in the first case the data and the quality shall be the same, while in the second case the quality shall be worse. You can find various compression algorithms that are better for various kind of data. Compressing and uncompressing data generally takes a lot of processing time, so the server performing the action needs to have enough resources in order to be able to process the info fast enough. One simple example how information can be compressed is to store how many sequential positions should have 1 and just how many should have 0 within the binary code as an alternative to storing the particular 1s and 0s.
Data Compression in Cloud Hosting
The compression algorithm used by the ZFS file system that runs on our cloud web hosting platform is known as LZ4. It can upgrade the performance of any Internet site hosted in a cloud hosting
account with us as not only does it compress data much better than algorithms employed by various file systems, but also uncompresses data at speeds which are higher than the hard drive reading speeds. This is achieved by using a lot 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. One more advantage of LZ4 is that it allows us to create backup copies much more quickly and on lower disk space, so we can have several daily backups of your databases and files and their generation won't change the performance of the servers. In this way, we could always restore all of the content that you may have removed by mistake.
Data Compression in Semi-dedicated Servers
The ZFS file system that runs on the cloud platform where your semi-dedicated server
account will be created uses a powerful compression algorithm called LZ4. It is one of the best algorithms out there and definitely the most efficient one when it comes to compressing and uncompressing website content, as its ratio is very high and it'll uncompress data faster than the same data can be read from a hard drive if it were uncompressed. This way, using LZ4 will quicken every Internet site that runs on a platform where the algorithm is present. The high performance requires plenty of CPU processing time, that's provided by the great number of clusters working together as part of our platform. In addition to that, LZ4 makes it possible for us to generate several backups of your content every day and have them for one month as they will take a smaller amount of space than standard backups and will be generated much faster without loading the servers.
