Data compression is the reduction of the number of bits which should be stored or transmitted and this particular process is quite important in the web hosting field due to the fact that info located on hard drives is generally compressed to take less space. You will find different algorithms for compressing info and they offer different efficiency depending on the content. A lot of them remove only the redundant bits, so that no data can be lost, while others delete unneeded bits, which results in worse quality when the data is uncompressed. This process consumes plenty of processing time, which means that a web hosting server needs to be powerful enough to be able to compress and uncompress data instantly. An illustration how binary code could be compressed is by "remembering" that there are five consecutive 1s, for example, rather than storing all five 1s.
Data Compression in Cloud 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 site hosted in a cloud hosting
account on our end since not only does it compress info much better than algorithms employed by other file systems, but it uncompresses data at speeds which are higher than the hard disk reading speeds. This can be done by using a great deal of CPU processing time, that is not a problem for our platform considering that it uses clusters of powerful servers working together. A further advantage of LZ4 is that it enables us to create backups a lot faster and on lower disk space, so we shall have a couple of 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 all of the content that you could have removed by accident.
Data Compression in Semi-dedicated Servers
The semi-dedicated server
plans which we offer are created on a powerful cloud platform that runs on the ZFS file system. ZFS works with a compression algorithm called LZ4 that exceeds any other algorithm you will find 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 more rapidly than it would be to read uncompressed data from a hard disk drive and owing to this, Internet sites running on a platform where LZ4 is present will work quicker. We're able to take full advantage of this feature although it requires quite a great deal of CPU processing time as our platform uses numerous powerful servers working together and we don't make accounts on a single machine like most companies do. There's a further benefit of using LZ4 - since it compresses data very well and does that extremely fast, we can also make multiple daily backups of all accounts without affecting the performance of the servers and keep them for a month. By doing this, you can always bring back any content that you erase by mistake.
