Data compression is the compacting of info by lowering the number of bits that are stored or transmitted. Because of this, the compressed data requires considerably 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 function in different ways and with a number of them just the redundant bits are erased, so once the information is uncompressed, there is no decrease in quality. Others delete unneeded bits, but uncompressing the data later on will lead to reduced quality in comparison with the original. Compressing and uncompressing content requires a huge amount of system resources, particularly CPU processing time, so every Internet hosting platform which uses compression in real time must have adequate power to support that feature. An example how info can be compressed is to replace 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 Web Hosting
The compression algorithm used by the ZFS file system which runs on our cloud hosting platform is called LZ4. It can upgrade the performance of any website hosted in a cloud web hosting account with us as not only does it compress info more efficiently than algorithms used by other file systems, but also uncompresses data at speeds which are higher than the hard disk drive reading speeds. This can be done by using a great deal 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. A further advantage of LZ4 is that it allows us to make backups much quicker and on less disk space, so we will have multiple daily backups of your files and databases and their generation won't change the performance of the servers. In this way, we could always recover any kind of content that you may have removed by accident.
Data Compression in Semi-dedicated Hosting
The semi-dedicated hosting plans that we offer are created on a powerful cloud hosting platform which runs on the ZFS file system. ZFS works with a compression algorithm called LZ4 that exceeds any other algorithm available in terms of speed and data compression ratio when it comes to processing website content. This is valid especially when data is uncompressed since LZ4 does that faster than it would be to read uncompressed data from a hard disk drive and because of this, Internet sites running on a platform where LZ4 is enabled will function at a higher speed. We can take advantage of the feature regardless of the fact that it needs quite a great deal of CPU processing time because our platform uses a large number of powerful servers working together and we do not create accounts on just a single machine like the vast majority of companies do. There's one more advantage of using LZ4 - considering that it compresses data rather well and does that very fast, we can also generate several daily backups of all accounts without influencing the performance of the servers and keep them for a month. In this way, you will always be able to bring back any content that you erase by mistake.
