Learn precisely what Data Compression is and find out how it may affect your websites and the experience of your website visitors.
Data compression is the reduction of the number of bits which need to be stored or transmitted and this process is quite important in the internet hosting field since data stored on HDDs is generally compressed to take less space. There are different algorithms for compressing information and they have different effectiveness depending on the content. A number of them remove just the redundant bits, so no data can be lost, while others erase unnecessary bits, which results in worse quality once the particular data is uncompressed. This method consumes plenty of processing time, therefore a web hosting server should be powerful enough to be able to compress and uncompress data instantly. An instance how binary code could be compressed is by "remembering" that there are five consecutive 1s, for example, in contrast to storing all five 1s.
Data Compression in Cloud Hosting
The cloud hosting platform where your cloud hosting
account shall be created uses the revolutionary ZFS file system. The LZ4 compression method which the aforementioned employs is superior in many aspects, and not only does it compress information better than any compression method that many other file systems use, but it's also considerably faster. The gains can be significant in particular on compressible content which includes website files. Even though it could sound illogical, uncompressing data with LZ4 is quicker than reading uncompressed info from a hard disk, so the performance of each and every website hosted on our servers shall be upgraded. The better and quicker compression rates also allow us to make a large number of daily backups of the full content in each and every hosting account, so if you delete something by accident, the last back-up copy that we have won't be more than a few hours old. This is possible as the backups take considerably less space and their generation is fast enough, so as to not change the performance of the servers.
Data Compression in Semi-dedicated Hosting
The ZFS file system that runs on the cloud platform where your semi-dedicated hosting
account will be created uses a powerful compression algorithm called LZ4. It's one of the best algorithms out there and certainly the most efficient one when it comes to compressing and uncompressing web content, as its ratio is very high and it'll uncompress data at a higher speed than the same data can be read from a hard disk drive if it were uncompressed. That way, using LZ4 will speed up every site that runs on a platform where this algorithm is present. The high performance requires lots of CPU processing time, which is provided by the numerous 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 will take a smaller amount of space than standard backups and will be created considerably faster without loading the servers.
