Moving education services to the cloud
-
Looks like DO might offer an educational discount if you get in contact with someone, but nothing on their site that is transparent about that. Just saw something in their FAQs. Vultr, that seems to be non-existent. Might be worth him to check that out I guess.

His environment is a very low budget network that he inherited in a rural town. To put it into perspective, the town is about 325 people. The school is obviously tiny. There is an elementary and a high school/middle school combo.
Looking for clarify: There is little money in the budget in general OR historically what they have was built on a very low budget? Unsure if you are talking about his available funds or the state of affairs.
There's little money in the budget. They get some help with things like e-rate and stuff from the state, but overall the district has very little money to spend.
Then that likely rules out AWS and Azure. Those are price premium services that don't appear to apply well here.
AWS didn't look expensive when comparing to what hardware costs are, but I also haven't compared them against DO & Vultr.
AWS is super cheap. BUT it requires a LOT of expertise. It is not designed for VPS use, it's a true and very focused IaaS cloud computing environment with the assumption of DevOps. Hard to believe that that is how your friend intends to work. But if he doesn't, AWS is going to suck.

Vultr supports Windows, though, I believe.

Without knowing the workloads and reasons for looking at any of these, we are very much guessing in the dark. Why are we talking about Azure or AWS? What role will they be fulfilling?
-
It might be good to go back to your friend and get a list of what he wants to run "in the cloud" and if he's open to changing his thinking on things.
For example, if he gets rid of all of the onsite servers, does he need AD anymore? If the servers are managing websites and files, he might be able to get away from AD altogether. use NextCould/ownCloud for files and the web servers, etc.
You're already using Google Apps, what aren't they providing that you need?

It could be any cloud provider... Azure, AWS, Vultr, Digital Ocean, etc. The role it's taking is eliminating the hardware in the buildings that carry higher upfront costs (refurbs are currently being purchased at a fraction of the price, but are still an added upfront cost). He's having to diagnose failing hardware when it goes down, pulling him away from other duties. Stuff like that... It's not just about saving money, it is mostly about displacing hardware that sits in the racks that add additional overhead like replacing drives/troubleshooting a faulty motherboard/etc.

Exactly. We are missing all of the pieces that make any of this make sense. What is the workload? Why have elastically expanding cloud computing options been listed as the only candidates? I know lots of times that AWS is the obvious answer, but none that would be obvious and could be selected without knowing the details.

That's why I'm here asking. Maybe I just don't know any better and could use some expertise on some different angles of approach.

Well but no. Cloud computing is expressly not for that purpose. This is a total misunderstanding of the role of cloud computing.
This article is focused on private, but applies to public here as well:
http://www.smbitjournal.com/2013/06/when-to-consider-a-private-cloud/
Azure and AWS are traditional cloud, so the opposite of what you are looking for. DO and Vultr are VPS built on cloud, so far closer. There are two different categories here that you are mixing together. This is why it was critical that we get the stated intention, because the assumed answer was totally wrong for the assumed need.

Well we need to start with the question, not with the answer. The thread led off with AWS or Azure... two nearly identical products. Basically, you already had the answer in mind. At no point as the question been asked yet. We aren't sure exactly what the question is. We are getting closer, but we are not yet there. Right now, every response is still assuming something that we don't know what led to that point, only that likely something has been overlooked. We can't evaluate in a meaningful way because we don't know what problem we are trying to solve.

This is just moving capex to opex. You can do that through leasing and financing moves. No need to fundamentally change architecture.

Warranties fix that. Or support contracts.

Generally to do stuff like this you would get a Scale HC3 cluster or something like that (something with full, integrated support) and throw it in a datacenter like Colocation America has. You get the lower cost of owning your own gear (compared to the price premium of cloud) while getting the remote support and full support of the datacenter and the integrated stack vendor. @scale @ChrisL @SamieWalters

The thread led off with AWS or Azure...
I cleaned up my OC and title a little bit...

I'm the last person to say that cloud computing is bad, I love it. But it's not a panacea and it has one real purpose - elastically expanding workloads. I know of no school that can leverage that. So paying the huge monthly cost premium to get that will be painful financially. And learning the skills needed to use AWS will be costly. Vultr can alleviate much of that, but you pay a little more to move to the VPS model on top of cloud computing in that case. You still maintain the fundamental problems.
Now if your workload is so small that you can't use a single server, then things change and Vultr or DO can make a lot of sense, this is where they rock. But if you are just moving stuff out of house, this is unlikely to make much sense.

So if they can't afford to have someone look after the hardware, and can't buy gear that has warranties attached to it. What are the alternatives for offloading those servers to a cloud provider? I asked why he couldn't go 100% Google Apps. He said he still has some legacy Windows stuff like Nutrikids, HVAC monitoring, etc. Currently inquiring about them moving those legacy services to another provider. One who holds the data themselves, and provide something web based. Instead of having him have their own server instance.

Just to run some quick numbers for you. A Scale HC3 cluster starts around $25K. That's a three node cluster with a ton of memory, IOPS and full HA (at the platform level.) You can run something like 128 Linux VMs or 64 Windows VMs on that (give or take rather a bit.)
To do the same on Vultr (figure 64 2GB Windows nodes) you would pay $2,304/mo without HA. If you wanted failover you would need to double that.
With Scale HC3 you would need three Windows Datacenter licenses plus the $25K base hardware. Let's call that $46K total.
Let's say that you run this workload for four years. Vultr would be $110,592.
If we subtract the capex of the Scale HC3 plus the Windows licensing from that we have $1,345/mo to spend on our colocation. We only need a 6U colocation space for this setup. Figure 8U to be safe. Our colocation cost will be far less than that, @ChrisL could give you a ballpark on that.
If you get bigger than the stated Scale HC3 size, the cost of colocation plummets quickly per workload. If you needed four nodes or five nodes you outpace cloud by crazy margins.
And the cloud cost assumes no HA, no backups. If you want either of those, the numbers climb quickly. But HA is already built into the colocation option in my example and backups are cheap to add (relatively speaking.)
-
For that example, I'm basically doing pricing based on 128GB of workload space. 64 2GB workloads, or two 64GB workloads would work out about the same. The numbers are not exactly flat, but flat-ish.

Our basic 10U option starts at $399/month. An extra 2U for whatever other goodies one might want to throw in.

Here is the bottom line... if they can't afford these things, then they can't afford them. There is no silver bullet for not having any money. Running Windows workloads is a price premium that shops do when they have lots of financial resources are want to buy more expensive systems in exchange for other benefits. The reliance on Windows while not being able to afford Windows is a problem. Why aren't they on something that they can afford?
Cloud providers are more expensive, in general, not cheaper. They are only cheaper when the workload is temporary, very small in total or fluctuates wildly and can be automated in its scaling.
It sounds like the workloads are tiny here. But that's say two servers there, likely 4GB each. That alone is $80/mo or $960/year. That's a LOT of money compared to one reasonable in house server. If cutting cost is the goal, nothing is going to compare to on premises hardware. And things like HVAC generally benefit from being local.
You can easily buy a quality, supported server for less money than even two VMs can be hosted.
