Data compression is the compacting of data by decreasing the number of bits which are stored or transmitted. In this way, the compressed info takes much less disk space than the initial one, so more content could be stored on identical amount of space. You will find various compression algorithms that function in different ways and with several of them just the redundant bits are removed, so once the data is uncompressed, there's no decrease in quality. Others erase unneeded bits, but uncompressing the data subsequently will result in reduced quality in comparison with the original. Compressing and uncompressing content consumes a significant amount of system resources, especially CPU processing time, therefore each and every Internet hosting platform which employs compression in real time must have enough power to support this attribute. 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 keeping the actual code.

Data Compression in Hosting

The compression algorithm employed by the ZFS file system which runs on our cloud hosting platform is named LZ4. It can improve the performance of any website hosted in a hosting account on our end since not only does it compress data much better than algorithms used by various other file systems, but it 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, which is not a problem for our platform considering that it uses clusters of powerful servers working together. An additional advantage of LZ4 is that it allows us to generate backups more speedily and on reduced disk space, so we shall have several daily backups of your databases and files and their generation won't influence the performance of the servers. That way, we could always restore the content that you may have deleted by mistake.

Data Compression in Semi-dedicated Hosting

The semi-dedicated hosting plans that we offer are created on a powerful cloud platform that runs on the ZFS file system. ZFS employs a compression algorithm known as LZ4 that outperforms any other algorithm these days in terms of speed and data compression ratio when it comes to processing website content. This is valid especially when data is uncompressed because LZ4 does that much faster than it would be to read uncompressed data from a hard drive and owing to this, sites running on a platform where LZ4 is present will function quicker. We're able to take full advantage of the feature although it needs quite a considerable amount of CPU processing time as our platform uses a large number of powerful servers working together and we do not make accounts on a single machine like most companies do. There's an additional advantage of using LZ4 - considering that it compresses data really well and does that very 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 will always be able to recover any content that you delete by accident.
