Data compression is the compacting of data by reducing the number of bits that are stored or transmitted. As a result, the compressed info will need less disk space than the initial one, so a lot more content can be stored using identical amount of space. There're different compression algorithms that work in different ways and with many of them just the redundant bits are erased, which means that once the information is uncompressed, there is no decrease in quality. Others remove excessive bits, but uncompressing the data at a later time will lead to reduced quality compared to the original. Compressing and uncompressing content consumes a significant amount of system resources, particularly CPU processing time, therefore each and every Internet hosting platform that uses compression in real time must have sufficient power to support this feature. An example how data can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" the number of sequential 1s or 0s there should be instead of saving the whole code.
Data Compression in Cloud Hosting
The compression algorithm used by the ZFS file system which runs on our cloud web hosting platform is called LZ4. It can upgrade the performance of any website hosted in a cloud hosting account with us since not only does it compress data more effectively than algorithms used by alternative file systems, but also uncompresses data at speeds which are higher than the hard disk reading speeds. This is achieved by using a lot of CPU processing time, that is not a problem for our platform because it uses clusters of powerful servers working together. One more advantage of LZ4 is that it allows us to generate backup copies at a higher speed and on reduced disk space, so we shall have a couple of daily backups of your files and databases and their generation won't affect the performance of the servers. That way, we can always restore all of the content that you may have erased by mistake.
Data Compression in Semi-dedicated Servers
The semi-dedicated server plans that we provide are created on a powerful cloud platform that runs on the ZFS file system. ZFS works with a compression algorithm called LZ4 that exceeds any other algorithm out there in terms of speed and compression ratio when it comes to processing web content. This is valid particularly when data is uncompressed since LZ4 does that quicker than it would be to read uncompressed data from a hard disk drive and owing to this, sites running on a platform where LZ4 is enabled will work at a higher speed. We can take advantage of this feature despite of the fact that it needs quite a lot of CPU processing time as our platform uses a number of powerful servers working together and we do not create accounts on a single machine like a lot of companies do. There's a further reward of using LZ4 - considering that it compresses data really well and does that speedily, we can also make several daily backups of all accounts without influencing the performance of the servers and keep them for a month. In this way, you'll always be able to bring back any content that you delete by mistake.
