Data compression is the compacting of data by reducing the number of bits that are stored or transmitted. In this way, the compressed info requires substantially less disk space than the original one, so more content can be stored on the same amount of space. You'll find different compression algorithms which function in different ways and with many of them just the redundant bits are deleted, which means that once the data is uncompressed, there's no decrease in quality. Others delete unneeded bits, but uncompressing the data later on will result in lower quality in comparison with the original. Compressing and uncompressing content takes a significant amount of system resources, especially CPU processing time, so every web hosting platform that employs compression in real time must have adequate power to support that attribute. An example how info can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" the number of sequential 1s or 0s there should be instead of saving the actual code.
Data Compression in Shared Web Hosting
The compression algorithm employed by the ZFS file system that runs on our cloud hosting platform is named LZ4. It can improve the performance of any Internet site hosted in a shared web hosting account on our end as not only does it compress data much better than algorithms employed by 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 considering the fact that it uses clusters of powerful servers working together. An additional advantage of LZ4 is that it allows us to create backup copies more quickly and on lower disk space, so we will have several 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 any content that you could have erased by mistake.
Data Compression in Semi-dedicated Servers
The semi-dedicated server plans which we offer are created on a powerful cloud hosting platform that runs on the ZFS file system. ZFS uses 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 particularly when data is uncompressed since LZ4 does that more quickly 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 work at a higher speed. We are able to benefit from the feature although it requires quite a considerable amount of CPU processing time because our platform uses a large number of powerful servers working together and we don't create accounts on just a single machine like a lot of companies do. There's an additional advantage of using LZ4 - since it compresses data very well and does that extremely fast, we can also generate multiple daily backup copies of all accounts without influencing the performance of the servers and keep them for a month. By doing this, you can always recover any content that you delete by accident.
