I notice that Linode talked a good bit about their bandwidth and included outbound bandwidth in their pricing model which DO does not. I wonder if DO has a similar model or if transfer capacity the only thing you have control over.

Bandwidth is cheap when you are in a datacenter.

I'm actually a little unhappy, it looks like they reduced the CPU count for my $20/mo instance. At this point there's basically no reason to stay with them now.

tl;dr: If you had 40 VMs on 8 cores before, you have 10 on 2 cores now. It is the same ratio of VMs:Cores but with stronger processors. Long version: "If you take the upgrade, you inherit the new plan specs, vcpus and all. We’ve greatly reduced the contention on these new machines compared to our old structure, and in testing this new arrangement provides much more consistent CPU time with less potential for steal. W…

Makes a lot of sense.

If your hosts have, say, dual 4-way CPUs, and you're giving your VMs 8 vCPUs, then a single VM can execute per clock cycle since a VM needs all of it's vCPUs made available to the guest OS. With 8 VMs, that means one VM is executing every 8th clock cycle.

If you "downgrade" those VMs to 2 vCPUs, then 4 VMs can execute per clock cycle, and that VM can now execute every other clock cycle instead of waiting 8 cycles. More work gets done, even though the amount of CPUs has gone down.

Since most VMs are probably executing work that only has 1-2 threads, then there's no loss from lack of parallelism. Remember, a VM needs all cores available, regardless of how many threads need to be executed.

Of course, some workloads do need that many threads, and so balancing number of cores vs. available execution time becomes a little more tricky. but based on what you shared, it sounds like Linode took a closer look and came to the same conclusion.

I forgot to benchmark the disk before I upgraded but here are some simple disk benchmarks on an upgraded linode (the $20 plan, now with SSD) $ dd bs=1M count=1024 if=/dev/zero of=test conv=fdatasync 1024+0 records in 1024+0 records out 1073741824 bytes (1.1 GB) copied, 1.31593 s, 816 MB/s $ hdparm -tT /dev/xvda /dev/xvda: Timing cached reads: 19872 MB in 1.98 seconds = 10020.63 MB/sec Timing buffered disk reads: 2558…

This is mine old $20 located in London, doing exactly nothing, I just created it last week, it seems very slow in comparison:

  dd bs=1M count=1024 if=/dev/zero of=test conv=fdatasync
  1024+0 records in
  1024+0 records out
  1073741824 bytes (1,1 GB) copied, 13,6791 s, 78,5 MB/s

  hdparm -tT /dev/xvda
  /dev/xvda:
  Timing cached reads:   3580 MB in  2.00 seconds = 1794.00 MB/sec
  Timing buffered disk reads: 336 MB in  3.01 seconds = 111.75 MB/sec

Earlier quoted context omitted.

I use a tiny VPS provider that is actually $20/yr. For sites that get a couple thousand hits per month it is perfect. Although I do not see it as a requirement in this price range, the uptime has been on par with the big names (I have known of one 5 hour outage in the 3 years I have been using it). Even DO's $5/mo now seems a bit steep now for the "I just had a random idea" type thing.

Care to share the provider you are using?

Ramnode is fantastic and cheap.

It looks like Linode are still leaving the "incredibly cheap tiny box" market to DO. Linode's cheapest option is $20/month, which makes it slightly less useful for the kind of "so cheap you don't even think about it" boxes that DO provide.

One reason Linode doesn't offer "tiny boxes" is that they, like other companies, are worried about running out of IPv4 addresses.

I doubt that's true. More likely it's because lower tier users are almost always disproportionally more demanding of help than higher tier ones. If you're going to make, for example, $1,000/m you're better off getting it from two competent, $500/m customers that don't need much help, rather than 100 $10/m customers who all need their hands held constantly. In Linode's case fewer users also makes contention less of an issue - the fewer VPSs per physical box, the better.

What if you want to have several tiny boxes? For example, if you want to host a mail server as a separate box for security, that's another $20/month. Or what if you need to use a different Linux distro for something? Another $20/month. A few examples like that add up fast.

Containers, e.g. through Docker, are good for that kind of thing.

Not if you need them to run on separate physical hosts. [e.g. A galera cluster]

I have a feeling it's a bit of customer service / risk mitigation. Obviously there are numerous exceptions but the sort of people that execute a lot of fraud, DDOS'ing, or simply amateurs playing around are also the sort of people that'll use DO before Linode. I imagine there's a heavy cost associated with hosting those users relative to ones happy to pay $20/mo instead.

I do not understand the difference between outbound bandwidth vs the transfer. Can you explain a bit please?

Yeah, honopu and kilburn got it right. My understanding is that transfer measurements are the maximum amount of data your instance can serve up in a month, while bandwidth is the speed at which it can do it.

Its like downloading a 1 GB file to your computer using a 56k modem or a cable modem... the transfer amount will be 1 GB either way, but the cable modem will be a hell of a lot faster due to the increase in its bandwidth. As you upgrade your plan with Linode, your "modem" gets faster, however DO doesn't mention the speed of their "modem" or if its speed is affected by the price level you select.

You mean https://www.digitalocean.com/pricing/ ? Seems to be working at the moment.

I am really sorry. I had Ghostery running, it took out the entire plan block so I was only able to see the FAQ.

Adblock also seems to remove their pricing info. Strange!
