Data compression is the compacting of information by decreasing the number of bits which are stored or transmitted. Because of this, the compressed information will take considerably less disk space than the original one, so a lot more content could be stored using the same amount of space. There're various compression algorithms that function in different ways and with a lot of them just the redundant bits are removed, so once the data is uncompressed, there is no decrease in quality. Others delete excessive bits, but uncompressing the data subsequently will lead to reduced quality compared to the original. Compressing and uncompressing content takes a huge amount of system resources, particularly CPU processing time, therefore every hosting platform that uses compression in real time should have enough power to support that feature. An example how information can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" how many consecutive 1s or 0s there should be instead of storing the actual code.

Data Compression in Cloud Website Hosting

The compression algorithm which we work with on the cloud hosting platform where your new cloud website hosting account shall be created is known as LZ4 and it is used by the advanced ZFS file system which powers the system. The algorithm is much better than the ones other file systems employ since its compression ratio is much higher and it processes data considerably quicker. The speed is most noticeable when content is being uncompressed as this happens more quickly than data can be read from a hard disk drive. Therefore, LZ4 improves the performance of every Internet site located on a server which uses this particular algorithm. We take advantage of LZ4 in an additional way - its speed and compression ratio let us produce multiple daily backups of the whole content of all accounts and store them for one month. Not only do the backup copies take less space, but also their generation doesn't slow the servers down like it often happens with some other file systems.

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 among the best algorithms out there and positively the most efficient one when it comes to compressing and uncompressing website content, as its ratio is very high and it will uncompress data faster than the same data can be read from a hard drive if it were uncompressed. Thus, using LZ4 will accelerate any kind of 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 large number of clusters working together as part of our platform. Furthermore, LZ4 allows us to generate several backups of your content every day and have them for one month as they will take much less space than regular backups and will be generated much faster without loading the servers.
