Data compression is the lowering of the number of bits that need to be stored or transmitted and this particular process is very important in the internet hosting field due to the fact that info located on hard disks is typically compressed in order to take less space. There are different algorithms for compressing information and they offer different efficiency based on the content. A lot 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 particular data is uncompressed. The method needs a lot of processing time, so a hosting server has to be powerful enough in order to be able to compress and uncompress data in real time. One example how binary code can be compressed is by "remembering" that there are five consecutive 1s, for example, as an alternative to storing all five 1s.
Data Compression in Cloud Website Hosting
The compression algorithm used by the ZFS file system which runs on our cloud internet hosting platform is called LZ4. It can upgrade the performance of any site hosted in a cloud website hosting
account with us because not only does it compress data much better than algorithms employed by various other file systems, but it uncompresses data at speeds that 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 due to the fact that it uses clusters of powerful servers working together. An additional advantage of LZ4 is that it enables us to generate backup copies more rapidly and on reduced disk space, so we shall have multiple daily backups of your files and databases and their generation won't influence the performance of the servers. That way, we can always recover all content that you could have removed by mistake.
Data Compression in Semi-dedicated Servers
The semi-dedicated server
plans that we provide are created on a powerful cloud platform that runs on the ZFS file system. ZFS employs a compression algorithm known as LZ4 that is better than any other algorithm out there in terms of speed and compression ratio when it comes to processing web content. This is valid particularly when data is uncompressed as LZ4 does that much faster than it would be to read uncompressed data from a hard disk drive and owing to this, websites running on a platform where LZ4 is present will function faster. We can take full advantage of this feature despite of the fact that it requires quite a lot of CPU processing time as our platform uses numerous powerful servers working together and we don't create accounts on a single machine like the vast majority of companies do. There is an additional reward of using LZ4 - given that it compresses data very well and does that very quickly, we can also generate several daily backup copies of all accounts without affecting the performance of the servers and keep them for a month. In this way, you will always be able to recover any content that you delete by accident.
