Data compression is the compacting of information by lowering the number of bits which are stored or transmitted. Because of this, the compressed info takes considerably less disk space than the initial one, so a lot more content could be stored on identical amount of space. You'll find different compression algorithms that function in different ways and with a lot of them only the redundant bits are removed, therefore once the info is uncompressed, there is no decrease in quality. Others delete unneeded bits, but uncompressing the data at a later time will result in reduced quality compared to the original. Compressing and uncompressing content consumes a large amount of system resources, in particular CPU processing time, so any hosting platform that employs compression in real time must have sufficient power to support that attribute. An example how data can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" the number of consecutive 1s or 0s there should be instead of saving the whole code.

Data Compression in Cloud Hosting

The compression algorithm employed by the ZFS file system that runs on our cloud web hosting platform is named LZ4. It can upgrade the performance of any website hosted in a cloud hosting account on our end since not only does it compress data significantly better than algorithms used by various file systems, but it uncompresses data at speeds that are higher than the HDD 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. An additional advantage of LZ4 is that it enables us to make backup copies more rapidly and on reduced disk space, so we can have several daily backups of your databases and files and their generation will not influence the performance of the servers. In this way, we could always recover all of the content that you could have deleted 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's 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'll uncompress data at a higher speed than the same data can be read from a hard drive if it were uncompressed. This way, using LZ4 will boost any website that runs on a platform where this algorithm is enabled. The high performance requires plenty of CPU processing time, which is provided by the multitude of clusters working together as part of our platform. In addition, LZ4 makes it possible for us to generate several backup copies of your content every day and keep them for a month as they will take much less space than standard backups and will be generated much faster without loading the servers.
