Data compression is the reduction of the number of bits that have to be stored or transmitted and the process is rather important in the internet hosting field due to the fact that data kept on HDDs is typically compressed to take less space. You can find various algorithms for compressing info and they offer different efficiency based on the content. A lot of them remove just the redundant bits, so that no data will be lost, while others delete unnecessary bits, which leads to worse quality when your data is uncompressed. The method employs a lot of processing time, therefore a web hosting server needs to be powerful enough so as to be able to compress and uncompress data instantly. An example how binary code may be compressed is by "remembering" that there are five sequential 1s, for example, in contrast to storing all five 1s.
Data Compression in Shared Hosting
The compression algorithm employed by the ZFS file system which runs on our cloud internet hosting platform is known as LZ4. It can improve the performance of any website hosted in a shared hosting account on our end because not only does it compress data significantly better than algorithms employed by various file systems, but it also uncompresses data at speeds which are higher than the hard disk reading speeds. This can be done by using a lot of CPU processing time, that is not a problem for our platform for the reason that it uses clusters of powerful servers working together. One more advantage of LZ4 is that it enables us to create backup copies more quickly and on less disk space, so we can have a couple of daily backups of your files and databases and their generation will not change the performance of the servers. In this way, we could always recover all content that you may have deleted by mistake.
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 is superior to any other algorithm on the market in terms of speed and data compression ratio when it comes to processing web 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 as a result, sites running on a platform where LZ4 is enabled will work faster. We are able to take full advantage of this feature regardless of the fact that 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 is a further reward of using LZ4 - considering the fact that it compresses data very well and does that very quickly, we can also make multiple daily backup copies of all accounts without influencing the performance of the servers and keep them for a month. This way, you'll always be able to restore any content that you erase by accident.
