Cheap open source cloud hosting

The new online hosting Nimbus.IO from SpiderOak is half the price of Amazon S3 and is based on open source software: the server and client parts are free and will be distributed on the open-source model (AGPL server, LGPL client). True, Nimbus.IO is still in a closed beta and the source is not available to everyone, but the developers promise to post codes on github soon.

There is nothing to say about the REST API, only that they are “similar to S3 and Rackspace, that is, the JSON format is used instead of XML”.

Service for online backup and file synchronization SpiderOak was launched in 2007. During this time, the developers rewrote software four times to manage the backend and changed the architecture of servers five times. According to them, there are no suitable solutions on the market for cheap and reliable long-term data storage. Existing GlusterFS, Linux DRBD, MogileFS, Riak + Luwak and Amazon S3 systems operate at RAID 2 through RAID 4 levels, that is, they work with a large overhead, which increases the cost for performance. They also wanted another - low cost with high reliability, albeit to the detriment of performance.

As a result, they achieved the desired and decided, in addition to the main business, to open an additional one: online hosting modeled on Amazon S3.

Unlike other cloud-based hosting systems, Nimbus.IO operates on RAID 6 , where data blocks and checksums are cyclically recorded on all disks in the array, there is no asymmetry in disk configuration.



Because of this, performance suffers: additional resources are spent on writing. But this is not critical for long-term data storage in backup systems. The most important thing that increases efficiency. As a result, the service Nimbus.IO was able to roll out rates twice lower than in Amazon S3.

Hosting 100 GB - $ 6 per month
External network traffic - $ 0.06 per 1 GB
PUT and LISTMATCH Requests - $ 0.01 per 1000
Other requests - $ 0.01 for 10 000 or free.

Now the service is in the process of closed beta testing. You can leave an email and wait for the invite, with which they promise two months of free hosting.
