Google Cloud maybe is superior in the pricing of compute, but it is actually more expensive on network egress traffic, object storage and block storage.

I recently created a simple tool (http://theprice.cloud/) to compare egress traffic, object storage, and block storage cost among AWS, Google Cloud and Azure. It seems like Googel Cloud is the most expensive one in egress traffic and object storage.

[nodesocket]

Except that Google Cloud cross zone and cross region (US) prices are much less than AWS.

    Ingress	                                Free  
    Egress inner-zone	                        Free  
    Egress cross-zone in the same region	$0.01  
    Egress cross-region within the US	        $0.01  

See: https://blog.elasticbyte.net/comparing-bandwidth-prices-and-...

[rpedela]

They seem pretty comparable to me? Cross-region is $0.02, inner-zone is free, and cross-zone is free or $0.01.

I could have sworn AWS prices cross-zone used to be higher maybe this changed recently. Or... I was just wrong. :-)

Don't feel bad, I'd forgotten this one: "Using a public or Elastic IPv4 address => $0.01 per GB". I'm sad we still don't have a proper split horizon DNS to encourage internal IP usage, but I can't imagine charging for it in the same zone.

[ahazred8ta]

TL;DR: Starting at - $3.69/GB/mo (US), US$4.11/GB/mo (Ireland),

assuming reserved instances with 1yr All Upfront pricing, not counting the really huge xlarge+SSD instances.

[jacquesm]

Which is its own form of complexity.

All these cloud offerings are priced so complex you can pretty much expect some nasty gotcha unless you spend an inordinate amount of time modeling your workload and traffic patterns.

And if something changes you can do it all over again.

[boulos]

Our egress pricing (from all sources) is certainly higher because we operate a private backbone rather than just dumping your packets straight onto the internet.

Your site seems to be hugged to death (so I can't see it), but there are lots of gotchas with S3 pricing (like rounding up file sizes with Infrequent Access and Glacier) that in our experience means our customers come out ahead. Glacier and Coldline also aren't really comparable in the sense that GCS always responds within milliseconds. We only economics to discourage frequent access from Coldline, not delays. As above, our egress is more expensive because it's better (we hear you though if your response is "I don't care! Give me cheaper instead, then!").

Disclosure: I work on Google Cloud.

[zjfroot]

Yes, I totally agree S3 pricing can be complicated with IA, Glacier, RRS, etc.

And it also gets complicated when comparing network egress, when region to region and egress to different parts of the world are taken into consideration. And GCP is actually more complex in the sense because it charges different prices for different egress destinations and AWS in comparison is one price for all of the world.

The most challenging part of making this tool is instead of displaying tons of options and dropdowns, I try to simply enough so that people get a general idea of the cost comparison of three major cloud providers, but not too simple to distort the reality.

AWS also has their own backbone. Starting at about 7 min: https://www.youtube.com/watch?v=bqPfQgatMko

[vgt]

Google's backbone is a little bit different. Google Cloud shares this backbone with Youtube, Maps, and the rest. Not only are there DC-to-DC cables, our backbone extends to a vast number of Edge POPS (more than AWS and Azure combined), detailed at [0]. Our DC-to-DC network is pretty great too, allowing things like Spanner to exist (minimizing P in CAP etc) at [1].

Here's what it means for you in practice:

- Google's Load Balancer supports a single global anycast endpoint.

- When your packet tries to hit Google network, it hits the nearest POP, which acts as an on-ramp to the network and traverses only Google network, not touching public.

- Similarly, when data is en route to a customer, Google network will take it all the way to the nearest DC or POP on its private backbone.

- Google by default gives you a global software-defined VPC. No need to create VPN tunnels between zones/regions/etc.

I work at AWS and I think there's definitely some similarities and differences. We do share our backbone with CloudFront, and hence our video traffic, of which there's quite a lot these days. We also advertise our network ranges broadly, it's our mission to carry the traffic as much as possible ourselves. So those aspects are very similar.

But a genuine difference is that we don't try to operate a global "seamless" network. The reason is that we optimize for the "A" in CAP. Our experience is that at the low-ish level of a network, it can be too easy for outages and availability issues to spread quickly. For example, with global networking then a misconfiguration or error can more easily propagate globally and bring everything down.

Instead, we have autonomous uncoupled regions and it's one of our core principles that faults and errors stay within these regions (or better yet, availability zones). That does mean that partitions can happen, but find that most customers use active-standby configurations (where it makes no real difference) for key data, and we also build the tools that work with partitionable networks at a higher level. For example Route 53 supports multi-region routing and failover, and does it measurably better than simple anycast routing can achieve.

Over time, we're offering more and more multi-region services, such as cross-region replication for data, but the coordination is done at higher levels where we can achieve higher levels of availability in simpler ways, built on top of a more solid foundation.

[boulos]

Yeah, at least one outage in the last year for us included the paraphrased "anycast is hard". There's definitely an advantage to limited-blast-radius services, but I wouldn't trade GCS's multiregional buckets for S3 CRR (the same applies to Datastore, etc.). We have strict reliability requirements for global services; our perspective is that some customers want regional control for regulatory reasons, and we're happy to meet those requirements. But composing a global or even multi-regional service on an untrusted, lossy network is "crazy".

Again, Disclosure: I work on Google Cloud (and this network existed when I got here!)

>For example, with global networking then a misconfiguration or error can more easily propagate globally and bring everything down.

This sounds like Nassim Taleb's antifragile meme [1].

If I was running IT for some large enterprise (which I'm not!) then I might replicate services on both AWS and Google Cloud. A bit like Apple try to have more than one supplier for their hardware components.

[delhanty]

You don't always need to have enterprise $$$ to take an antifragile approach though.

I'm mirroring my private Git repositories between Gitlab.com and Bitbucket, which can be done for $0.

I might even end up paying for the bottom end Github.com ($7 per month) and Gitlab ($4 per month) accounts and have three way redundancy.

[pbarnes_1]

Just in case you can forward this on... AWS EC2 eu-west-2 (London) to GCP Network Loader Balancer is about 12ms round trip for some reason. Most other anycast services located in London are 0.5-2ms round trip.

Just something I noticed recently. :)

[valarauca1]

During/After the dot com crash Google purchased a lot of backbone fiber at dirt cheap prices.

The DC-to-DC interconnects google has are extremely robust.

[vosper]

Though Glacier is hooked to S3 (for obvious reasons) I don't think it's relevant to a discussion of bandwidth egress costs. If you're frequently pulling things out of Glacier then you're using it wrong.

[boulos]

I agree! Most conversations that somehow talk about GCS being more expensive usually are "oh actually, AWS just charges less for egress" (which isn't a non sequitur but is effectively orthogonal). Again, I'd respond directly if the site weren't hugged to death :).
