Data compression is the lowering of the number of bits that need to be stored or transmitted and the process is quite important in the internet hosting field due to the fact that data located on hard disks is generally compressed so as to take less space. You will find many different algorithms for compressing information and they offer different effectiveness based upon the content. A number of them remove just the redundant bits, so no data will be lost, while others remove unnecessary bits, which results in worse quality when the data is uncompressed. This method needs plenty of processing time, so a hosting server needs to be powerful enough to be able to compress and uncompress data immediately. One example how binary code may be compressed is by "remembering" that there are five consecutive 1s, for example, in contrast to storing all five 1s.
Data Compression in Web Hosting
The compression algorithm used by the ZFS file system that runs on our cloud hosting platform is called LZ4. It can improve the performance of any site hosted in a web hosting account with us since not only does it compress data significantly better than algorithms employed by alternative file systems, but also uncompresses data at speeds which are higher than the hard drive reading speeds. This is achieved by using a lot of CPU processing time, which is not a problem for our platform since it uses clusters of powerful servers working together. One more advantage of LZ4 is that it enables us to make backups much more rapidly and on lower disk space, so we shall have multiple daily backups of your files and databases and their generation will not affect the performance of the servers. That way, we could always restore all the content that you could have deleted by mistake.
Data Compression in Semi-dedicated Hosting
The semi-dedicated hosting plans which 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 surpasses any other algorithm available in terms of speed and compression ratio when it comes to processing website content. This is valid especially when data is uncompressed as LZ4 does that faster than it would be to read uncompressed data from a hard disk and for that reason, Internet sites running on a platform where LZ4 is present will function at a higher speed. We are able to take advantage of the feature regardless of the fact that it requires quite a large amount of CPU processing time as our platform uses a wide range of powerful servers working together and we don't create accounts on a single machine like a lot of companies do. There is an additional benefit of using LZ4 - considering that it compresses data really well and does that very quickly, we can also generate multiple daily backup copies of all accounts without influencing the performance of the servers and keep them for an entire month. In this way, you can always recover any content that you erase by accident.
