Moz Dumps Amazon Web Services, Citing Expense and 'Lacking' Service

Perhaps as a freelance consultant right now I take a sharper look at the costs involved - if a client has, say, $50k to budget on a project, I really don't want $10k of that to go to hosting if it doesn't need to - I'd rather it be available for my services directly (obviously) or to give us more play for marketing, testing, whatever.
I've known a couple of small to medium sized companies where they were using AWS rather strategically as part of their services - dynamically spinning up test environments for running parallel testing, off-peak data crunching, etc - but even in those cases, there weren't gigantic savings vs other options.
What bugs me most is the false dichotomy I get when I talk about this with friends; their choice is presented as either use AWS or "hire a full-time sysadmin, buy multiple server-grade boxes and manage all this in a rented data center". I've been told Amazon is saving people "easily" $100k/year by not having to hire staff and buy expensive hardware. Hrmm... not all hardware is expensive, and instead of hiring a sysadmin, you've now got multiple developers spending time learning the AWS API, and building critical business processes around AWS, tying you to Amazon for the long haul, all while they could be focusing more on line-of-business stuff that you hired them for in the first place.
I don't doubt that in some cases there's robust cost savings, but it's never struck me as a terribly cost-efficient way of doing any web stuff. In some cases it may be the only way to deal with certain problems, but in those cases cost probably isn't a consideration anyway.
On a $50k project, how are you even dropping $10k on AWS? I've found a medium instance (~$100/mo) handles with ease 100k+ visitors/mo without breaking a sweat.
I too find it difficult to think of a $40K project which is both likely to spend $10K at Amazon, and which can acquire equivalent resources (hardware, power, space, admin, etc.) for significantly under the same cost.
Not impossible, but real-world examples would be nice.
That's the biggest mistake one can make : host a traffic intensive app (even lots of graphics) on AWS.
1) Order a server with lots of bandwidth from a provider such as Hetzner, 100tb or Leaseweb (or possibly OVH, though I haven't used them personally).
Low performance hardware is fine, though you'll either want enough ram to fit your frequently used images, or an SSD.
2) Install nginx as a reverse caching proxy. There's an example configuration in the nginx docs. Requests to /blah/something.png on your nginx server are sourced from www.yoursite.com/blah/something.png, but cached for the period you specify.
3) In your DNS, set static1.yoursite.com, static2 etc to point to the newly created server. This is for browser parallel downloads.
4) In your html, point your static assets randomly amongst the newly created domains (best if this is done automatically).
In this way, your newly created box soaks up the load of the static assets traffic, but it has no additional cognitive overhead. You don't change your development model at all.
If you have a switch in your code to source the images from the original domain, you can go back to hitting AWS instantly should the box have problems, so the risk is very low.
You can get a 10 gigabit unmetered server from the Leaseweb volume network for 600 euros/mo. The bandwidth is lower quality than AWS, but if you have high utilization you can pump more than a petabyte from the server a month, which would cost approximately $60k from EC2.

>> At 100TB/mo., pure file delivery, you'd need to be an Enterprise customer. Let me know if this works within your budget.
> The Enterprise plan comes at $3000/mo.
This is not really intended as a direct reply to you, but I think that price point illustrates mgkimsals point well: I have a Django-based project with about the same amount of visitors per month on an old rented vserver that costs about 7€($10)/month. Yes, you have to set up nginx once, but as mgkimsal mentioned setting up your project for using AWS is not done without any work either. (And of course the load heavily depends on the type of project, so perhaps my visitors could mean only a fraction of the computational load of the ones in your example.)
This is the kind of thing that I've just started documenting at http://tweaked.io/
Typically when my clients do a project, they're budgeting out for the year, so that's $8k/year, not per month.
AWS would be cheaper with reserved instances, but then (IIRC) you're prepaying in advance for something you may not need. Even if it's cheaper, it's sort of defeating the purpose of "i can scale on demand". (which, yes you can still do, but you're back to 'on demand' pricing).
As someone else pointed out, some of where AWS gets you is the storage and traffic. I've got a setup right now where I need to have at peak 2-3 servers to handle traffic, as there's a moderate amount of computation going on - it's not all the time, nor every day, but when I need it, I need it. And it's processing documents (photos, etc) and we need to store them. Then show them back to the user. With on demand pricing, and the amount of traffic, this can be ~$600+ per month (*12 = ~$7000/year).
Could I optimize the code more to use less CPU, and perhaps require 1 less server? Possibly. Could I optimize some other stuff? Possibly, but that will cost more time, in order to save money with AWS.
Reserved instances would probably be the best, but if we ended up needing more later, it's harder to go back 6 months later and say "hey, we need more $ for X", as the budget was already done and processed for project Y.
I've got some projects like this at digitalocean, and one on month-to-month dedicated hardware, and the pricing is about 50%, mostly because of the built-in storage that AWS line items separately.
Can AWS do more functionally? Sure. Do we need it? Usually not, and paying for that infrastructure when it doesn't match the core needs isn't usually an option. Elastic IPs would be nice, but we could get much of that utility at linode if need be, and still pay less.
That's why you mix. We know our base needs, these are reserved instances 100% utilization. When something comes up that drives a lot of traffic the on demand instances kick in automatically. If you have somewhat "regular" spikey traffic you can buy reserved instances with less utilization and still save vs raw on-demand pricing.
I'll be the first to say we could do this all cheaper with some other VPS and a bunch more labor, but we are using a _ton_ of AWS services. My personal/moonlighting customers I use DO where a single nginx/sql droplet can handle everything with ease for small load sites
This absolutely hits the nail on the head.
The dumb part is that the next option down, renting dedicated hardware, seems to be effectively identical with regard to server administration overhead. The only difference is that the time to provision is longer (4 hours with our host), and billing monthly instead of hourly.
In either case, you need to know how you are setting up new machines, monitoring them and deploying your application to them.
The part that really kills me is this though. Using AWS is supposed to be good for start-ups because it allows you to get started quickly and think about building your product rather than focusing on technology that someone else could handle. The problem is, how you are going to scale your technology on AWS is a problem you need to think about very early.
Even the lowest end dedicated hardware is so fast that you can have millions of daily active users before you even need to move beyond a single box. It's amazing how many things you don't need to think about when you only have a single box.
I'm sure it's gotten better but when we colocated I had to project what type of traffic and storage (photos) we'd need. That led us to lease a few servers from HP. We were able to reuse hardware we owned already for reporting type tasks. But I got 1TB storage servers when we were using about 1/5 of that.
In my current startup (photos, again) we were on AWS from the beginning. I think we could save money now if we wanted. But when we first started out all we needed were 2 micro instances and S3.
I'd say we've increased capacity by 8x since then.
But here's the kicker. Since we started on AWS we were able to keep our costs fairly low at the beginning and as we grew we never had to make any long term projections. We simply added capacity (literally) on a weekly basis.
Once you start to buy into the AWS ecosystem you begin to reap some serious benefits. You simply cannot think of AWS as just EC2 instances. Of course, the trade-off by going all in is some level of lock-in (though this can easily be minimized).
Having done both I am happy to pay AWS more for the ecosystem.
--
We're using EC2, ELB, SNS, ElasticTranscoder, RDS, S3, Route53, CloudSearch, CloudFront & Glacier.
The exact same thing can be said for renting dedicated servers. You can add new ones at any time and it's fairly quick. This is exactly how we scaled up as well. Adding new servers day to day as required.
Yes, it takes 4 hours rather than 4 minutes but unless you are dynamically scaling up and down throughout the day in direct response to load, you are not using the versatility that you are paying for with AWS. Few people are.
Once you start to buy into the AWS ecosystem you begin to reap some serious benefits. You simply cannot think of AWS as just EC2 instances. Of course, the trade-off by going all in is some level of lock-in (though this can easily be minimized).
And there is nothing stopping you using these other cloud services without EC2. If you look around at other vendors, you might even be surprised at the prices you can get.
For example, we worked out at one point that in our case CloudFront would cost over over $50,000 per month for what we were paying about $4000 per month with a different CDN.
Perhaps it's slightly more expensive to start with AWS, cheaper as you scale (WRT man hours) and gets (prohibitively) more expensive once you hit a certain scale.
I don't doubt there are plenty of reasons to be off AWS. Lots of evidence exists to support that. And vice versa.
This. On the mobile app/social network thingy I'm working on now, I reduced it down to a single process. I've got one thing to watch, and on a single box, I expect—like you said—to scale to millions of users.
It's run by Tata, which is pretty massive plus according to http://cloudharmony.com/ it's got pretty good performance, especially considering the price.
I guess problem for most of you (it seems pretty US centered around here) may be that they don't have a presence in the United States (they're good in Europe, Asia and India though).
Anyone have any experiences with them?
But it is weird that people don't know about Linode or Digital Ocean (which is incredibly cheap compared to AWS and actually works, which the micro EC2 instances often stop working if you put a load on them). Even Rackspace would be much better option.
So even if you are just thinking of very popular companies, there are well known reliable options out there that are vastly better values for most things than EC2. Then there are probably dozens or even hundreds of small companies that would probably provided even better value and service.
For our longer stateful processing or apps that need to be available 24/7 with no variability in load we have purchased our own hardware (a process that has been going on for over 18 months). Owning the equipment plus the data center will run us approx 1.2 million including growth to build a hot back up.
It should be noted, staffing cost was not a factor. We must have staff to manage 1000s of servers at AWS or at our own data centers. The biggest factor was paying for compute on boxes that crashed and yielded nothing we could use to move our business forward. Well, I take that back, we got really good at check points and rollbacks. Other than that, not much.
No matter how you slice it, AWS and other cloud services are a great service for the right types of processing, and applications.
Skinner Moz CTO
Paying for 70-100 hours of compute and having the server crash in the middle of calculating your predictive analytics not exactly all that bright either. So, we bought our own gear.
AWS works and worked with us pretty damn closely as we pulled apps out of the cloud.
(Oh, and thanks for the information you've already shared - even if you can't answer my curiosity here…)
As an aside, AWS has everyone beat when it comes to regions however. We can be close to our customers in Europe, US and so on.
To date, no one is spinning up cloud fronts and services in more areas than AWS. It will take the MSFT , IBMs and the like to move the global cloud along. MSFT just needs to realize not everyone wants Sharepoint, SQLServer and .net.
Which service you use is really situational. Plenty of good ones out there. AWS is just one!
I run technical operations for a company with a fraction of your footprint (but growing quickly). We're at the point where we are growing out of the RAX public cloud but by my calculations, the decision to run our own private cloud in colocation vs. lease one from a service provider is (financially) a wash.
From a practicality standpoint, the scales tip towards leasing bare metal from a provider. I'm curious to hear your experiences with colo. How many folks do you have working in your colocation facilities doing hardware maintenance? What about network engineering? I presume you also keep a sizable stock of spares?
1: http://www.rackspace.com/managed_hosting/managed_colocation/
Now for the long winded:
1. We do have a decent amount of spares but not a ton. Our contracts require replacement parts within hours to a day. Some items like F5 gear we have two and no spare. They just replace their gear in hours.
2. Each data center has 24/7 support that can do some minor tasks.
3. Yes, Networking is a pain and you need the right people to do it. It is not cheap either! Luckily our VP of Tech Ops is a networking guru.You mess up networking and you are hosed. Our first networking guy wasn't exactly Tops! So, we know first hand.
Having said all of that, for us there are economies of scale. It is the case if we want to test different machines, databases or any other combination at scale it could cost us several hundred thousand dollars just to run the tests. Yep, we have dropped over 100k for testing at scale. Its simply not sustainable and an irresponsible way to spend investors cash. Also, when you add in multiple environments for dev, test, staging and integration you can quickly see we consume a lot of boxes. So, many in fact, a lot of colocation/cloud services will not work with us unless we plop down large amounts of cash. Let's also factor in AWS wants large up front spend for reserved instances. Thus, if you need the capital to get the amount of compute you need to run your business it is not very hard just to call Dell, Cisco, Nimbix, Equinix or any other vendor and negotiate our own deals. If any of these companies can get half our spend a year they are willing to at least talk.
Nothing reserved because we never wanted to be tied to the platform for long, although we ended up staying on longer than I wanted to due to difficulties in migrating away.
Yes, I realize we could have saved a lot with longer contracts. But the costs would still have been much higher than what we're paying now.
RDS crashed (completely) for us 2 years in a row, on exactly July 4th. We never got a straight answer from Amazon and their support system is a nightmare. Performance was always an issue.
Our main servers are now hosted on Hetzner (surprisingly).
We've had issues here and there with individual machine performance but nothing catastrophic and their customer service has been good.
For redundancy, we replicate back to the US onto Rackspace (and small EC2 instances for additional redundancy) servers and can switch over completely if need be.
We were worried that latency (because servers are in Germany) would be an issue but it hasn't. Also, in addition to US customers, we have a lot of customers in Japan so it doesn't seem to make much difference.
It's probably not for everybody and it's certainly not "cool" but it's worked very well for us.
Edit: our needs are relatively inelastic, which obviously makes AWS a poor choice to begin with. That was something we learned a little later in life as a startup.
Personally I think the best is some mix of both public and private, so you have the scalability when you really spike but have cheaper more capable machines handling baseline and things like analysis or storage workloads.
If you read the Moz report, they appear to have gotten a new CEO and are now building out a datacenter presence. They spent 7MM+/yr on AWS in 2013, there is no way that won't be viciously slashed by renting racks.
Yeah, this isn't really surprising. As soon as the convenience/expertise 'tax' exceeds hiring your own, it makes sense to make the jump.
Are people surprised that big enough organizations have their own accountants or lawyers?
That may be true compared to doing your own racks, but not compared to renting managed servers at a monthly basis.
Every time I price out AWS vs alternatives, I end up with the same: If you need a server for more than about 8 hours a day, renting a managed server at a monthly basis tends to come out substantially cheaper. And that doesn't increase sysadmin workload; in fact many hosting providers now offers APIs for provisioning monthly billed services too, just generally with lead times in hours instead of minutes/seconds, so it takes really bursty traffic before taking the hassle of auto-scaling with cloud instances becomes worthwhile.
That elasticity only makes financial sense when you use it properly. Like, if you keep your entire infrastructure turned on all the time, and cranked up to 11, but you aren't using reserved instances, then you are missing the point and you might as well just build/rent your own datacenter space and run your own servers (or pay someone like Rackspace to do it).
If you are using AWS, then you need to make use of reserved instances and the elasticity to spin down things that are being underutilized. If your infrastructure is too fragile to safely handle spinning up and down instances, then you probably are missing the cloud or aren't taking full advantage of what it has to offer.
I'm not saying Moz wasn't doing all of these things, I'm just saying that if you are spending $7 million a year, but aren't doing the appropriate capacity planning, then you are making a mistake.
At the very least, the exercise of doing real capacity planning by moving into physical data centers probably had a lot to do with the cost savings as well.
However, if the numbers don't work out on reserved instances and you have a pretty steady demand, going with your own infrastructure makes total sense.
Still, as my colleague observed, it must be the only business in the world you can spend $1m a year on and get only basic support, with web-only tickets that take hours or days to get a resolved.
To be fair to AWS we don't need support often; we really only have problems when everyone else does (major outages) and we can follow the status of that online, we don't need to call someone to be told "we're working on it". Also our account manager is responsive and pro-active in helping us out, and they've put us on free Business Support trials a couple of times, but because we need it so infrequently there's really no reason for us to fork out for it.
They're horrifically expensive, and low quality.
It's really, really sad that so many startups have been convinced that it's "cheap" when it's almost comically expensive and lousy.
here's a source, since you're attacking and disbelieving everybody who doesn't love AWS: http://searchcloudcomputing.techtarget.com/news/2240203992/N...
The issue you mention (where you have to treat sg's as being immutable if you want them to work reliably) is another problem with the sg's.
It really is truly terrible support.
did you actually try, or are you just rationalizing your enormous AWS spend?
They're some of the largest players in marketing and analytics, especially since Adobe's $1.8B acquisition of Omniture in '09.
Or (more likely) is it that only 17% of people realized they do "marketing technology"?

As more websites setup default blocks for all accesses from AWS services, the Moz exit was inevitable.
FWIW, this is specific to Cloud Sites, which is like one-click Wordpress/Drupal deployments.
folks... NOBODY gives a fuck about you at those companies, and you better believe it. not the account manager, not the engineer working on your 5 day old ticket, not the sales guy who probably isn't even paid a decent commission, and certainly not the executive management who is pulling down 300k+/year annual salaries plus huge stock grants and bonuses (check out the SEC filings!)
a well managed cluster of computing equipment running baremetal operating systems, hypervisors of your choice, and maybe something like openstack or docker is both profitable for the vendor and a MASSIVE price reduction for the customer.
if you know what you're doing, you're spending $10k/month for $100k/month worth of equivalent amazon services. yes, you heard me right. it is an order of magnitude of cost savings. once you scale past $10k/month, using amazon for all your needs is an INCREDIBLY STUPID business decision.
the genius of AWS, of course, is that they disguise all their marketing as technical spec sheets and deliberately design their collateral and sales process to appeal to the "engineer" types with acronyms, numbers, and highly specific jargon.
it's quite clever. but not clever enough to fool everyone. and those that are fooled, learn eventually that maybe paying 300% more than you should isn't that smart.
Disclaimer: Been using OVH for the past year. Sure, there's downtime (like 1 hour every couple of months), but it's so cheap I can afford a lot of redundancy.
thanks.
I don't have the experience with large AWS setups to comment about the cost implications, but improved reliability and efficiency strikes me as questionable - AWS's reliability has improved markedly over the last 18 months to the point I cannot remember when their last major outage was.
I'm keen to hear other peoples' thoughts on this..
I'm not very familiar with Moz, but it looks like they have an analytics product, which is probably particularly sensitive to slowdowns.
The cloud market is maturing now and a hybrid private/public model I think is going to become more of the norm, for companies that are large enough that this makes sense.
It is cheaper to run your own hardware when you are big enough, and then use AWS for failover / load spikes / cool tech, etc.
About two thousand dollars a month gets half a rack with a high-speed, highly-reliable connection in co-location. The lease payments on several extremely high performance, flash storage rack servers would be a couple thousand dollars a month. Throw on some shared nothing redundant virtualization, and you have the equivalent of an army of 4xmegaxlargemongos.
AWS has a place (such as being the redundant offsite backup for that scenario, or for extremely variable service requirements), but endlessly on here we see people disbelieving alternatives make sense.
But you don't come to AWS just for EC2 instances. You're there to combine their portfolio of services in various ways. Because of this, it'd probably be wrong to just compare $1000 on AWS vs what you are paying now.
Technical details:
I don't know exactly how they do it but my guess is that they are I/O bound on the crawling side, then CPU bound on the parsing and processing side. I'm assuming they use different machines for those tasks.
On the crawling side, the index with 60-70 billion URLS was using 80 cc2.8xlarge machines with a backup on 200 c1.xlarge machines. (http://moz.com/blog/one-step-back-two-steps-forward)
(DISCLAIMER: I'm in the same industry. I am a developer with working for an indirect competitor. I know a few engineers and non-engineers who work at Moz.)
I would imagine the main bottleneck, by far is the I/O with reading/writing to the database clusters and search index. Crawling is relatively cheap, it's storing that data that's hard.
Moving to your own hardware lets you actually reason about what's going on in a controlled environment, and at the scale that Moz is working at allows us to get hardware that's robust, well-supported, and reliable enough to have a pretty serious net positive overall.
In other words you pay more to use Amazon cloud + you still have to hire and pay sysadmins to babysit the whole pile of Amazon cloud mess.
That's what MSFT is perfectly positioned to solve with Azure + their excellent set of mature tools and services.
MSFT came late to the cloud game (as Ballmer was mostly doing in all other games for the last 10 yrs) - but they are getting this enterprise play right step by step.
Pair (US), ByteMark (UK) and Linode (global) are top choices for budget stuff. ByteMark has setup VMware boxes with freenas storage for us in the past. (For us being sysadmins, budget dedicated is way cheaper than AWS.). Pair and Bytemark support are top notch.
For enterprisey stuff self-service/remote hands/support... OpSource, SoftLayer and RackSpace.
Also the killer cost in a datacenter is power followed closely by labor, so reducing needs by using the simplest / COTS solution can be much cheaper. Servers tend to sprawl, not decrease... So cull viciously.
I'd love to see some numbers on this though.
Sure AWS is expensive for 24/7/365 applications, but I suspect there's some "in between ground" where Amazon's economies of scale make it less expensive to just pay them to deal with owning and maintaining the hardware (and ensuring you write your applications to be able to deal with cloud instances vanishing underneath you randomly).
(but it's still better to have a webserver on AWS, that simply 302s to your "real" services, or only provides a skeleton web page, though 302'ing is better, without it you'll quickly run into difficulties with same origin policy. 302 redirects will also change much faster than dns updates).
There is so much more to running a server farm than just buying a couple racks of computers and upgrading the FiOS line.
We bought a $300 air conditioner from Home Depot, cut a whole in the server room door with a sawzall and installed the air conditioner. Ok technically we only used the air conditioner in that configuration on the weekends when there was a human in the room and the main building air was off (we couldn't override it) but I like that story.
You're not going to get 5 nines this way, but you would be surprised at how much you can do, even when there exactly zero dedicated sysadmins.
And it's surprisingly less hardware than most people think. Stack Overflow runs off of two machines. A few pieces of decent networking equipment and some fans and they're probably not even consuming half a rack.
Turns out running their own hardware is exactly what they ended up doing and even with staff and other costs, runs a fraction of AWS. https://news.ycombinator.com/item?id=7155165
In reality the sweet spot is in the planning. If talking about only compute, colo your 24/7 servers and spin up extra capacity when needed in the cloud provider of your choice (what Moz appears to be moving towards).
Something we make heavy use of is Glacier and I don't know of a good alternative on that front.
For what 95% of the people here on HN need, 2 or 3 decent servers running off of a business FiOS line will be more than adequate for even their wildest ambitions. 99% of the remainder could make do with a rack or two of equipment, a generator, dedicated a/c and some loving electrician work. And even then if they need quick surge capacity expansion, they can still bring in AWS to augment their home-rolled stuff.
If keeping your stuff in-house isn't sexy enough, colo'ing it is still cheaper than AWS in most cases.
There's probably a fraction of 1% of the startups here that actually need what AWS offers. But the prevailing attitude here is that everybody's appointment reminder photo sharing web app is going to require AWS when they'd be perfectly well serviced, and be far more responsible with investor money, with something far less capable. The problem, as I'm seeing in the comments here, is that basic industry know-how (like how to assembly a reliable high-performance server from parts) seems to be largely absent in the industry.
I would never roll with a FiOS line to run my services, for one I doubt their TOS supports it. I'm not sure anything but the smallest of startups could pull that off, and even then they'd be better served spinning up a few droplets on DO.
If you have a 'moderately large' AWS configuration, you need a corresponding 'moderately large' DC deployment with plans for redundant network links and redundant power. I can't express the importance of that: anything you run that you care about needs to be in a controlled, monitored environment. Not a home-rolled franken-rack powered by a single non-symmetric line without an SLA. Not to mention proper fire suppression.
In some industries, designating some office space for your "server room" and building it out to data center specs is pretty common and surprisingly not all that expensive. I'm surprised by both that lack of can-do attitude here on HN as well as the basic know-how about it. I guess the demographic here skews towards young-hip-cloud-framework-I-don't-know-how-to-do-anything-for-myself-everything. But it wasn't all that long ago that buying some empty 1u and 2u cases, and sources parts from the local hardware shop, installing them in racks that you bolted to the floor of your server room, that you fitted out with redundant backbones, industrial a/c and enough amperage to blow out the transformer down the street was what people actually did and it's not that hard. Hell, one of the points of RAID was to enable companies trying to save a buck on such setups to exist in the face of very expensive enterprise class hardware disk options.
(edit) and this is exactly what they did https://news.ycombinator.com/item?id=7155165
To save myself chastising yet another HN'er about this my last comment
- Redundant fiber connections to multiple independent ISPs
- Battery backup and generator failover
- Redundant HVAC
- Waterless fire suppression
- 24x7 staff presence
- Security systems and personnel
These are all economies of scale. If you're just running a couple of racks you're either throwing away money by paying for all this or making yourself irresponsibly vulnerable to things that can and will go wrong.
> If you're just running a couple of racks you're either throwing away money by paying for all this..
You're paying for all of it anyways. Especially if you colocate, and then you're paying for their costs plus whatever they charge on top of that. Money you pay into somebody else's profits, that you can self-service is literally throwing away money.
It sounds like the OP built their own hardware, but colos it all in a datacenter. https://news.ycombinator.com/item?id=7155165
Colocation is a great solution (in fact, the solution) to the scale issue.
However, on Ubuntu server at least there are literally about two commands to run for upgrading the OS.
