Data compression is the compacting of information by lowering the number of bits which are stored or transmitted. As a result, the compressed info needs much less disk space than the initial one, so much more content could be stored on the same amount of space. You can find different compression algorithms that function in different ways and with some of them just the redundant bits are erased, therefore once the info is uncompressed, there's no decrease in quality. Others remove excessive bits, but uncompressing the data later will lead to lower quality compared to the original. Compressing and uncompressing content consumes a large amount of system resources, especially CPU processing time, so each and every hosting platform that uses compression in real time must have enough power to support this attribute. An example how info can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" how many consecutive 1s or 0s there should be instead of saving the actual code.

Data Compression in Cloud Website Hosting

The compression algorithm that we work with on the cloud hosting platform where your new cloud website hosting account will be created is called LZ4 and it is used by the cutting-edge ZFS file system which powers the system. The algorithm is far better than the ones other file systems employ as its compression ratio is higher and it processes data significantly quicker. The speed is most noticeable when content is being uncompressed as this happens faster than info can be read from a hard disk drive. As a result, LZ4 improves the performance of any Internet site located on a server that uses the algorithm. We take advantage of LZ4 in an additional way - its speed and compression ratio make it possible for us to make several daily backup copies of the whole content of all accounts and store them for a month. Not only do our backup copies take less space, but their generation will not slow the servers down like it can often happen with some other file systems.

Data Compression in Semi-dedicated Servers

The semi-dedicated server plans which we provide are created on a powerful cloud hosting platform which runs on the ZFS file system. ZFS works with a compression algorithm called LZ4 that surpasses any other algorithm on the market in terms of speed and compression ratio when it comes to processing web content. This is valid especially when data is uncompressed because LZ4 does that faster than it would be to read uncompressed data from a hard disk and because of this, sites running on a platform where LZ4 is present will function quicker. We are able to take advantage of this feature although it requires quite a lot of CPU processing time because our platform uses many powerful servers working together and we never create accounts on just a single machine like most companies do. There is a further benefit of using LZ4 - considering the fact that it compresses data rather well and does that extremely fast, we can also make multiple daily backups of all accounts without influencing the performance of the servers and keep them for a month. That way, you'll always be able to recover any content that you delete by accident.
