I love how DO focuses on what matters the most: Inexpensive VMs and scalable block storage. If I had to pick two, those would be them!

Well except being 4 years late to the block storage game? Seems they have an uphill fight. Aws and gce match them on low end droplet price and offer much more. No local ssd but not sure what % of apps really need local ssd. DO effectively forces you to pay for local ssd for all of your servers.

I like their straight forward pricing. $0.10 USD per GB per month. No IOPS limits. That said, how do you prevent a rogue droplet from going crazy and hogging up all of the SSD I/O?

Unless I missed it, I saw "no need for complicated formulas to determine the overall cost for transactions or IOPs limit," which I do not read as "no IOPS limit." I was looking but could not find any word on performance.

I read it as they either silently limit you, or have a free for all and let the traffic duke it out for iops.

Reminder that just a few weeks ago DigitalOcean rolled over on one of their customers and took down 38,000 websites after receiving a claim of infringement from the NRA against a parody site hosted on surge.sh: http://motherboard.vice.com/read/nra-complaint-takes-down-38...

Just a reminder that most businesses would do this exact same thing in this position and the problem is with the policy and enforcement.

Get out and vote for the right people this November.

This helps me with a nicer deployment setup. I was always keen on 'rebuild from scratch' rather than 'update stuff and hope you're idempotent and have captured all changes' but transitory data was always the problem. Now I can start building a new updated droplet and the only downtime will be that needed to detach and reattach the block storage containing the db etc. Anyone see a flaw in this? (I know there are other…

Perhaps not a flaw, but some issues with your setup are implied.

If you're rebuilding from scratch because you're not sure that you can update things, then you're probably in need of a configuration management tool (I'm a big fan of saltstack[1], mostly because I don't like Ruby or DSL's, but there's lots of options out there[2])

If you're worried you're going to lose transitory data, it sounds like you don't have a trusted and tested backup/archival/recovery process in place. So having it stored on a single EBS / DO BS / etc means you're still exposed. If you're rebuilding and rolling data over, in this scenario, I'd be copying, rather than relocating, any precarious data repositories.

This is EXACTLY the thing that I need for one of my droplets! I love how there is nothing "special" about it - it's just a disk that you can attach to a droplet. I'm sure that under the hood there's some kind of magic going on, but it looks like it's nicely abstracted away. This is what I hoped block storage would turn out to be - here's a block device, use it like one.

As soon as this rolls out to the region I've got that droplet in, I'm going to pull the trigger on it. I might even spend the effort to migrate my droplet to a supported region just to get this.

Find me a viable candidate who will work for the people and I will.
