    An alternative to shared hosting

    4th June 2008

    Personal communication resulted in a link to slicehost, who provide VDS/VPS services at prices as low as 20$/mo, which is comparable in price to good shared hosting plans, and is cheaper than Dedicated plans.

    I’m considering a move from shared hosting, and found Slicehost attractive. For 20$/mo, you get guaranteed 256MiB RAM, 10GiB disk and 100GiB traffic, which is sufficient to host several under-1k-per-day sites.

    The only thing which isn’t spoken aloud is the guaranteed CPU speed. Based on the numbers provided: 16GiB total RAM per server, quad-core CPU, and CPU quotas set equivalently to RAM quotas, I came to a conclusion that 20$-plan guarantees ~125MHz of CPU (take 16 GiB, multiply by 4 20$-plans – you get 64 “slices” – virtual servers; quad core CPUs were quoted as 8+GHz – I assume that’s the sum of the core frequencies, thus 8GHz divided by 64 slices gives as little as 125MHz guaranteed per slice).

    The better slice you buy – the more CPU is guaranteed, so for 1024-RAM slice you’d have a minimum of 500MHz of CPU.

    However, slicehost describes their CPU-clamping system as the one allowing “bursted” performance, if others aren’t actively using their CPU shares. So it must be much better than what I’m calculating here. And even if it’s not, then for some applications it’s better to have a 125MHz-clamp on CPU, than have a 20-seconds maximal CPU time limit.

    Still, I’m looking for reasonably-priced collocation services in Ukraine – e.g. those (currently unavailable) from Volia, starting at 40$/mo for the rented physical VIA C7-based server with enough traffic included.

    Update: I now have my own server collocated in Ukraine. This blog still lives on a shared hosting, but I’m considering the move to own server (where I have the biomed half-dead site and resource-hungry COTRASIF tool).
