Data compression is the compacting of info by decreasing the number of bits that are stored or transmitted. As a result, the compressed info needs less disk space than the original one, so more content can be stored using the same amount of space. There are various compression algorithms that work in different ways and with several of them only the redundant bits are erased, so once the information is uncompressed, there's no loss of quality. Others delete unnecessary bits, but uncompressing the data at a later time will lead to lower quality in comparison with the original. Compressing and uncompressing content needs a huge amount of system resources, particularly CPU processing time, therefore any hosting platform which uses compression in real time should have adequate 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" the number of consecutive 1s or 0s there should be instead of keeping the whole code.

Data Compression in Cloud Web Hosting

The compression algorithm which we work with on the cloud web hosting platform where your new cloud web hosting account shall be created is called LZ4 and it's used by the state-of-the-art ZFS file system that powers the platform. The algorithm is greater than the ones other file systems use because its compression ratio is higher and it processes data significantly quicker. The speed is most noticeable when content is being uncompressed since this happens even faster than information can be read from a hard drive. For that reason, LZ4 improves the performance of any Internet site hosted on a server that uses this particular algorithm. We take advantage of LZ4 in one more way - its speed and compression ratio allow us to generate a couple of daily backups of the full content of all accounts and keep them for one month. Not only do these backup copies take less space, but also their generation does not slow the servers down like it often happens with alternative file systems.

Data Compression in Semi-dedicated Hosting

The semi-dedicated hosting plans which we provide are created on a powerful cloud hosting platform which runs on the ZFS file system. ZFS employs a compression algorithm called LZ4 that is superior to any other algorithm available on the market in terms of speed and data compression ratio when it comes to processing website content. This is valid particularly when data is uncompressed since LZ4 does that faster than it would be to read uncompressed data from a hard drive and as a result, Internet sites running on a platform where LZ4 is enabled will function faster. We are able to take advantage of this feature regardless of the fact that it requires quite a large amount of CPU processing time because our platform uses a huge number of powerful servers working together and we do not make accounts on just a single machine like most companies do. There is one more reward of using LZ4 - since it compresses data very well and does that very quickly, we can also make multiple daily backups of all accounts without influencing the performance of the servers and keep them for an entire month. That way, you can always restore any content that you delete by mistake.
