Data compression is the compacting of information by decreasing the number of bits that are stored or transmitted. This way, the compressed info requires considerably less disk space than the original one, so additional content could be stored using the same amount of space. There're many different compression algorithms that function in different ways and with many of them only the redundant bits are removed, therefore once the info is uncompressed, there's no loss of quality. Others erase excessive bits, but uncompressing the data at a later time will result in lower quality compared to the original. Compressing and uncompressing content needs a significant amount of system resources, and in particular CPU processing time, so every hosting platform that uses compression in real time should have adequate power to support that attribute. An example how data can be compressed is to replace 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 Cloud Hosting
The compression algorithm employed by the ZFS file system which runs on our cloud internet hosting platform is named LZ4. It can supercharge the performance of any website hosted in a cloud hosting account on our end as not only does it compress data more effectively than algorithms used by alternative file systems, but it also uncompresses data at speeds that are higher than the hard disk drive reading speeds. This is achieved by using a great deal of CPU processing time, which is not a problem for our platform for the reason that it uses clusters of powerful servers working together. An additional advantage of LZ4 is that it enables us to create backups more quickly and on reduced disk space, so we will have several daily backups of your databases and files and their generation will not change the performance of the servers. That way, we can always recover any kind of content that you may have removed by accident.
Data Compression in Semi-dedicated Hosting
The ZFS file system which runs on the cloud platform where your semi-dedicated hosting account will be created uses a powerful compression algorithm called LZ4. It's among the best algorithms out there and positively the best one when it comes to compressing and uncompressing web content, as its ratio is very high and it'll uncompress data faster than the same data can be read from a hard drive if it were uncompressed. Thus, using LZ4 will speed up any site that runs on a platform where the algorithm is enabled. This high performance requires a lot of CPU processing time, which is provided by the multitude of clusters working together as a part of our platform. What's more, LZ4 enables us to generate several backup copies of your content every day and have them for one month as they'll take much less space than typical backups and will be created considerably quicker without loading the servers.
