Here is my $5 digitalocean slice (created a few months ago): # 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, 3.7375 s, 287 MB/s # hdparm -tT /dev/disk/by-label/DOROOT /dev/disk/by-label/DOROOT: Timing cached reads: 16394 MB in 2.00 seconds = 8205.62 MB/sec Timing buffered disk reads: 868 MB in 3.00 seconds = 289.17 MB/sec

287 MB/s vs 816 MB/s is huge. Linode is really doing a good job here. I have 4 VMs with them and am very happy. Can't wait to make this move.

I think these new nodes are still pretty lightly used, give it a few months and then do a comparison. Benchmarking VPS/cloud instances can be tricky since you might be on a quite node or a heavily utilized node. You really need to provision many machines and run the checks at random times over a period and then average the scores out.

I upgraded some of my VMs and they all failed to boot on their own and I had to manually boot each one after the migration.

Why do I pay Linode $20/month instead of paying DO $5/month(1)? Because Linode treats their servers like kittens (upgrades, addons/options, support), and DO treats their servers like cattle. There's nothing wrong with the cattle model of managing servers. But I'm not using Chef or Puppet, I just have one server that I use to put stuff up on the internet and host a few services. And Linode treats that one solitary ser…

I don't see that distinction at all. Both Linode and DO provide persistent local storage. Both let you resize your server. And now, they're competitive on price; Linode even has hourly billing. Granted, DO has lower-end plans than Linode. But I don't see any indication that DO treats servers as disposable or fungible whereas Linode doesn't.

I don't think anyone's ever gotten good hard numbers, but just from having seen a lot of people's anecdata over the years, my general impression is that Digital Ocean seems to have more short-term outages and to oversubscribe their boxes a bit more.

Parallelizability isnt always possible, but you should normalize the speed you get per dollar. 287 MB/sec / $5 ~ 57 MB/sec/dollar 816 MB/sec / $20 ~ 40 MB/sec/dollar

    287 MB/sec / $20 ~ 14 MB/sec/dollar
I don't think MB/sec/dollar makes sense simply because disk speed does not scale. If you need a (very) fast disk, Linode is obviously the better choice.

Right, but they provide additional IP addresses only if you can provide evidence that you need them (e.g., SSL certs).

Don't almost all web servers/browsers use SNI now? I don't see why you'd need multiple IPs for running multiple SSL sites nowadays. I have done multiple SSL sites on one IP for years.

IE on XP and Android 2.x are the notable things that don't support SNI. Some people still care about these.

If the difference matters, a $5 DO node likely isn't cutting it.

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.

> the "incredibly cheap tiny box" market How big is that market, really? I keep a small VPS around for whatever (I like Hetzner), and I'm sure lots of nerds are the same. But for any usage that's even a little bit serious, $20/month is peanuts.

Bummer, they're taking away 8 cores for the cheap plans and replacing it with 2. Does anyone know if the new processors will offset this difference? I don't know the specs of the processors. Linode's announcements usually come in triples...I'm excited for number three. Let's hope its some kind of cheap storage service.

Cores presented to your machine by the hypervisor do not have a 1 to 1 relationship with physical cores. In the world of virtual machines, how many cores you have is meaningless. For example, my VMWare server is a single 8 core processor, but my VM's only see 2 cores, as that's the way I prefer it and I believe VMWare recommends this or even one core. Those 2 virtual cores can access all 8 physical cores. The only re…

If you had a host machine with 8 cores, and a virtual machine with 2 cores, the virtual machine will only possibly use 25% of the CPU resources of the host machine -- one vCPU cannot be schedule in parallel across more than one physical core.

However it is advisable to minimize the vCPUs in VMs because it greatly enhances scheduling -- if a VM has 8 vCPUs allocated to it, with some hypervisors that lack advanced co-scheduled it won't be scheduled until 8 cores are available, and in some situations it will sit on 8 cores during its duration whether it is only using 1 or all. If you have a large number of smaller VMs, scheduling can greatly improves.

This isn't true for all hypervisors and situations. You mileage may vary.

That's only when comparing $5 to $20. Does the $20 DO model also have 287MB/s?

Not with the tiny amounts of memory offered at that price. 2GB is very easy to burn through in short order. Anything less than 8 feels really claustrophobic. I've always needed memory more than disk. Really wish I could pay some of these providers just for a one off increase of a few extra gigs of memory without tiering up which includes an entirely higher level of storage that I will not ever use.

Huh? Containers are quite lightweight; you can run several of them in 2 GB of RAM.

I was referring more to the applications within than container overhead.
